During the last week of my holidays at Biddeford, Maine, this summer, Colias philodice was abundant and in fine condition, and a great many were taken, in the hope that among them there might be some C. interior, but none of this species were found.

1. Field Observations on the Habits of the Species, by R. Weith.

Nannothemis bella, Uhl., is one of the smallest of dragon-flies. Of its life-history we have had no knowledge up to the present time. Until the publicetion of Williamson's Catalogue of the Dragon-flies of Indiana, last year, it was recorded only from our north-east Atlantic seaboard. I have frequently met with it in Elkhart and St. Joe Counties, the two northermost counties in Indiana; but, what has been most perplexing to me, only in a few very restricted areas, these areas not exceeding 50 yards in length by 25 yards in width from margin of lake. The only places I have met with it are at Simonton Lake, a distance of four and one-half miles from the City of Elkhart, Indiana, and Indiana and Baldwin Lakes, thirteen miles north-east of Elkhart, on the boundary line that divides Indiana from Michigan. In the latter place, on a smaller area than at Simonton Lake, the imago is very numerous. Frequent endeavors to find the species at other places where similar conditions prevail proved unsuccessful.

In September, 1899, I found this species fairly plentiful on sand dunes, in Rondeau Provincial Park, Kent Co., on the shore of Lake Erie. The sand dunes occupy a considerable area there, and in some places near the lake shore are thinly wooded with red cedar (Juniperus virginianus).

While connected with expeditions sent out by the Department of Entomology and Ornithology, University of Nebraska, it has been the writer's good fortune to spend a portion of the summers of 1900 and 1901 in the extreme north-western corner of Nebraska in collecting the insects, birds and mammals of the region. Naturally the butterflies, the study of which has been something of a “hobby” with him for some years past, came in for no little share of attention.

The larvæ of Phlyctœnia ferrugalis, Hbn., have been since 1897 the cause of some loss to roses in the large houses of Mr J. H. Dunlop, Toronto. References to this occurrence will be found in the Reports of the Entomologist and Botanist to the Dominion Experimental Farms for 1899 and 1900.

On the 12th November, 1900, a visit was paid to the above houses by Mr. Gibson, and specimens of the mature larvæ found feeding both on violets and chrysanthemums were secured, as also some larvæ in other stages of development. These all changed to pupæ and in due course the moths appeared, the pupal state lasting from 17 to 20 days.

At the time of writing my article on the “Red Wing” species of Catocalæ I was in doubt about a few forms, as there were some I had not seen. Since writing that, Mr. O. C. Poling, of Quincy, Ill., kindly sent me for examination some of these, and many others from his large collection; besides enriching my cabinet with several species it did not before contain. To bring the “Red wings” into what seems to be their proper relationship my last article needs a revision, which I will here make before taking up the “Yellow Wing” forms.

Marmorata should probably precede Concumbeus, where it may be found in this series. Mr. poling's new species, Frenchii, should follow Californica and its varieties. Mr. Heury Edwards described both Jessica and Portia as related to Californica. These, with Mr. Poling's species, Hippolyta and Luciana, it seems ro me should constitute what might be called the Californica group.

The following list of the Coccidæ found to inhabit Canada is complete, so far as the published records show, together with some other information derived from corresponding with Prof. Cockerell, Dr. Fletcher, and Mr. John Dearness. Much, however, has been obtained from material sent to me for identification. In reviewing the list it will be seen that Ontario has 25 species of Coccids credited to her; while Ottawa has 18; Toronto, 6; Quebec, 3; Prince Edward Island, 3; Nova Scotia, 4; New Brunswick, 2; and British Columbia, 6. One has been found in an ants' nest, 8 in greenhouses, and there have been 8 new species described from Canada. There are 46 species, 27 of which are native to North America, 14 are introduced, and 4 whose home is unknown, but which were probably introduced. The large majority of the species have been found by Dr. Fletcher, or at least have passed through his hands. Much credit, however, is due Mr. John Dearness, who has taken great interest in looking for these very injurious insects, and has sent me several very interesting species.

The past two seasons in Kansas have proved fairly profitable to the collector of Coleoptera. To the plains collector the “open” season for successful collecting extends from April 1st to October 15th. If he is so fortunate as to reside beside or near a wooded stream, his “open” season covers the cycle of the months, as winter sifting proves almost as profitable as collecting during the summer months, especially if he looks after the small things, and he is not possessed of the genuine collector's spirit if he does not look carefully after the minute things in insect life.

Andrena krigiana, n. sp.

♀.—Black; mandibles rufous at tips, toothed near the apex; basal process of labrum short, subquadrate, emarginate; clypeus somewhat shining towards apex, where it is rather distinctly punctured, elsewhere opaque and reticulated; face before ocelli longitudinally striate; facial foveæ quite short, not descending below insertion of antennæ, filled with a fine pubescence which appears black; antennæ short, joint 3 as long as the next three together, or nearly so, apical joints dull testaceous beneath; thorax throughout opaque and finely reticulated; enclosure of metathorax poorly defined, but rather strongly rugose; pubescence of head and thorax rather thin and dull fulvous; wings subhyaline, nervures and stigma honey-yellow, second cubital cell about one-third as long as the third, oblique, receiving the first recurrent nervure at, or a little before, or a little beyond, the middle; abdomen shining, rather sparsely and rather evenly punctured, apical margins of segments pale testaceous, hardly subfasciate, fimbria fulvous; scopæ pale, the hairs of hind tibiæ rather strongly plumose. Length, 8 mm.

The first attempt at an arrangement of the N. Am. Lepidoptera, including a reform in the nomenclature, which I published in 1896, calls for some corrections. In the present list I have endeavoured to supply these, but, doubtless, there are others which have escaped me. Since 1896, Lord Walsingham and Mr. Durrant have fixed the types of the genera Tortrix, Tinea, Alucita and Pterophorus, in the two former confirming my doubtful determination of 1895 and correcting the type of the last named genus to monodactyla. I have followed Dyar, in Can. Ent., in using Hipocritidæ instead of Arctiidæ. I cannot find the sure type of Geometra or Noctua. I reject, however, the latter name, since it was differently used by Klein in 1753, and the assumption of 1758 as the basis of nomenclature is arbitrary. The present arrangement is based on that of the Syst. Lep. Hild., 1895. The views of Dyar with regard to the value of the larval tubercles are adopted. The superfamilies are regarded as parallel growths. It seems probable that the Hesperiades, Sphingides, Saturniades and Bombycides (Agrotides) are separate developments from the Tineid phylum. The subfamilies mark breaks in the sequence. This latter is arbitrary, but no scientific reason has been adduced for changing the general Linnæan plan, which is practically the most convenient. With regard to the family names, the oldest term, employed in a collective form and not preoccupied, is retained. At a time when new Catalogues are preparing, the publication of systems will be useful. The diurnals are arranged according to the diphyletic classification of 1897, the sequence and value of the groups are given by me in April, 1900. With regard to the origin of the Lepidoptera, the Micropterygides show hymenopteriform and trichopteriform, the Hepialides neuropteriform characteristics.

Head narrower, eyes nearer together than in Salda, ocelli approximate, frontal ridge weak, becoming obsolete at base of tylus, bucculæ enlarged; antennæ with the two distal joints incrassate, rostrum as in Salda, basal joints very thick, second elongate, terminal very slender. Prothorax bearing two very prominent conical tubercles on anterior lobe, which is narrow, cylindrical, not carinate anteriorly; posterior lobe short, carinate laterally, widening rapidly to humeri.

Form and general appearance of pulchella; colour pattern of scaber, but with extra markings, and different colours on pronotum and elytra. Length, 5.5 mm.; width, 1.75 mm.

Vertex slightly angularly rounded, transversely depressed before the apex; front as in scaber, the margin between front and vertex more strongly produced. Pronotum slightly angularly rounding anteriorly, much more so than in scaber; lateral angles scarcely apparent, rounding from eye; pronotum and scutellum convex, elevated.

About ten years ago, in sifting swamp mosses for Coleoptera, I met with certain active little insects which, despite their wingless form and almost microscopic size, were recognized as members of the order Hymenoptera. Some of the individuals so captured were afterwards described by Ashmead, in his Monograph of North American Proctotrypidæ, as Bœus minutus and B. piceus. Subsequently, B. americanus, Howard, and B. niger, Ashmead, were also discovered at Ottawa. My solitary example of the former species was found sluggishly crawling on the under surface of a stone in the chilly temperature of early spring, and one example of B. niger was taken with a sweeping-net at the end of September. With these two exceptions, all my specimens of the genus were taken from moss collected at the beginning of winter. All were females, as might be expected, for it is the females oniy of bees and wasps, and probably of all hymenoptera hibernating in the imago condition, that survive the winter in these northern lands.

In his note on p. 191, Dr. Dyar raises an interesting question, concerning which I would like a general expression of opinion for my own guidance.

Among the material received for study by M. Guenée from the British Museum, perhaps also from other sources, was a considerable number of specimens and drawings collected, bred or drawn by John Abbott, of Georgia.

Not all of the Abbott drawings went to the British Museum, for I saw some in Paris ten years ago, and not all the Abbott drawings have been identified, for I saw in the British Museum many pictures representing insects thet have not been taken since, so far as I know, while I identified a few recently described, among these century-old drawings.

There is a great lack of uniformity in labeling insects; owing to which it is often impossible to distinguish the name of the locality from that of the collector; and with reference to the date of capture, it is impossible to discover what is meant (when the day of capture is less than the 13th), on account of some collectors placing the day of the month first, and others the month.

For instance, a specimen taken on May 10, 1901, would by some be labeled 10, 5, 1901, and by others (chiefly amongst Americans) 5, 10, 1901. On passing from one collection to another, the recipient would be undecided as to whether the figures referred to May 10 or Oct. 5.

Again, now that exchange abroad is much more common than formerly, it is insufficient to give simply the village or wood in which the insect is taken.

♀.—Length slightly over 3 mm.; antennæ pale brown, 2 + 15 jointed, the first two joints darkened; eyes united on vertex; thorax reddishbrown, dorsally shining, naked, with four very thin longitudinal bands of hairs; femora pale brown, tibiæ and tarsi darker; wings well fringed with hairs; abdomen nearly naked, bright red, ovipositor and a dorsal apical patch white; ovipositor moderately long.

Pulvinaria Hunteri, n. sp.—Old, dried and wrinkled female scales, cream-colour, more or less mottled with patches of red-brown, and the outer margin practically red-brown. Ovisac clear white, texture as in innumerabilis, and not so large. The size of the scale, cleared and spread under cover class, practically hemispherical, is from 6 to 7 mm, in diameter. The texture of the scale is quite thin and requires little boiling in caustic potash to make it very clear and colourless.
