In May, of the present year, at Coalburgh, I bred a large number of larvæ from eggs laid by tharos, var. marcia; also several from eggs laid by ajax, var. Walshii; and from eggs laid by Lyc. pseudargiolus; and all of the chrysalids of tharos, and part of those of the other two species, were placed in small tin boxes as they formed, and at different intervals thereafter, 10, 20, 60 minutes up to some hours, and one and two days, were laid in the ice box on top of the ice. The box was supplied with ice once a day.

In the early spring, from the middle to the end of April, Prof. Lintner and Mr. Hill have taken near Albany a rather small and inconspicuously colored moth, remarkable for its diurnal activity. At first sight I did not recognize it as belonging to the Tortricidæ, but on examination it shows the family characters and seems to be allied to the European genus Cheimatophila. But it is not vein 4, but vein 5 that is wanting on the hind wings, and the other characters sufficiently separate our species.

I have had upwards of 500 examples of the species before me in making these comparisons, most of them bred, but many taken in the field during several years past, since my attention has been attracted to the variation manifested. Many others I have brought together from localities as far apart as those mentioned. And I can well corroborate the words of Drury, applied to tharos, now more than an hundred years ago: “In short, Nature forms such a variety of this species that it is difficult to set bounds, or to know all that belongs to it.”

Last spring, while collecting beetles under the bark of decayed logs, I met with numbers of the larvæ of Arctia isabella (hairs brown in the middle, black at each end of larva,) about to spin up. Not knowing their hybernating habits, they had always baffled me, and under the impression that they would require another season to mature, had been turned loose. I collected some twenty, put them into a box with cotton and paper scrap, and they at once spun up, all but four. These wandered up and down for a week, having some want, and wasting away.

I received, 25th June, from Mr. C. P. Whitney, New Milford, N. H.,a cluster of about 50 eggs of this species, laid on the under side of a leaf of Diplopappus umbellatus, date of deposition not stated. The larvæ hatched 28th June. The food plant not being obtainable by me, I gave them leaves of Chelone glabra, on which phaeton feeds, but so long as the least bit of the dry leaf of Diplopappus on which they hatched remained, the larvæ declined the Chelone, and then after starving many hours they attacked it vigorously. But, meantime, for want of proper food, several died.

I have received both sexes of this species from Prof. Feraud, of Orona, Maine. It is a prettier species than A. bella Cham., with the fascia much more distinct. Zeller describes only the ♂. It has the head and palpi dark brown, with a very faint purplish tinge; the antennæ with annulations of dark purple and silvery white ; the body and legs dark purple, the legs annulate with white ; hind wings pale purplish with darker ciliæ ; thorax and fore wings rich deep purple, appearing in some lights to be thickly dusted with brightly scintillating golden scales.

Upper side blackish-brown ; primaries have the costal margin to cell and nearly to apex densely covered with fulvous ; the basal area and the inner margin sprinkled with fulvous scales; and the cell wholly deep fulvous except towards the outer end, where through the middle runs an oar-shaped blackish stripe; midway between cell and apex an elongated yellow-white spot, cut into three by the sub-costal nervules, the one of these spots nearest costa nearly lost in the fulvous ground ; across the disk an oblique band of yellow-white spots, the upper one small and in the upper discoidal interspace, placed a little outside the costal spot, the lower one in the submedian interspace, the spots widening as they proceed towards inner margin, and the 3rd and 4th deeply excavated on the outer side.

The collection which forms the subject of this Paper was kindly presented to the Ent. Soc. Ont. by Mr. D'Urban, and the specimens are kept for reference in the form in which they were given, because they were determined by Mr. Walker, the labels all being in his handwriting and many of the insects being types of his species. Many of the species were collected in the valley of the River Rouge, and some of them are mentioned in two papers in the Canadian Naturalist and Geologist, vol. 5, pages 91-6, and vol. 6, pages 36–41.

The “species” of the black-winged group (Mormonia of Hübner)comprised in the genus Catocala have been largely augmented as the collections are increased throughout the country. Without doubt, when we shall be thoroughly conversant with the immature stages, our knowledge of the species will be more perfect.

About the last of March my friend, Mr. Allen Curtiss, a botanist, brought me some Orange twigs infested with the Orange Scale Insect (Aspidiotus Gloverii). On examining them with my pocket lens, I was surprised to see numerons smail black mites running in and out of the scales, and which no doubt prey upon the eggs of the Scale Insect, and probably prevents their increase. Since then I have been enabled to examine them with a more powerful microscope,and I think they are entirely new to science.

In “The Bulletin of the Geo. Survey,” v. 3, p. 134, I have referred to two species or varieties of Batrachedra found by me in Colorado. Some of these specimens found at Colorado Springs I referred doubtfully to the European species B. præangusta. others found higher up the mountains I named B. Clemensella, stating, however, the doubt whether the two forms were really distinct. After the grerter portion of that paper was in the hands of the publisher, I received from Mr. Stainton two specimens of præangusta, by which I was enabled to recognise my B. Clemensella as a variety simply of that species, and to increase my doubts whether the supposed species were really distinct

For the purpose of further testing conclusions stated on p. 174 regarding Homopteras lunata, edusa and Saundersii, I have secured all observed at my sugar since the former writing.

There are 38 “lunata,” 23 “Saundersii” and 18 “edusa.” Having opportunity to examine these while fresh, I observed the anatomy of the sex organs in each specimen as captured. The result verified the view previously advanced–the lunatæ were all females, the Saundersii and edusæ all males.

Fore wings pale carneous brown shaded with dusky; terminal space more blackish. Median lines fine, black, approximate, angulate. A curved sub-basal shade on internal margin. Reniform narrow, outwardly curved or oblique, white and contrasting, set in a dark suffusion of the disc. Subterminal line even, with a costal angulation. A fine dark terminal line at base of concolorous fringes. Hind wings pale, shining with traces of median shades and the fringes slightly carneous ; abdomen concolorous with hind wings.

In the Editor's “Notes on Cantharides,” published in the December No. of the Entomologist, there are some particulars in reference to Meloe angusticollis which differ somewhat from my own observations on this species, extending over a period of seven years. According to my experience, Meloes make their appearance in the perfect state about the end of August or beginning of September, when they feed greedily on Ranunculus acris. Later in the season, when the abdomens of the females are much enlarged, they pair, and later still–sometimes after the first frost–they deposit their eggs and invariably die that season.

In the collection before me are the following species referred to Polia, but in the absence of a series of the European forms I am not clear that they are finally to be lelt in this genus. I have separated under the name of Pachypolia atricornis a stout and shaggy species, taken by my friend, Mr. Westcott, which has strongly pectinated antennæ, a character not accorded by Lederer to the European species, but one which is only doubtfully of generic value. To distinguish these species from Hadena is certainly difficult.

The type ♀ specimen of Samia Gloveri having been presented by Mr. Strecker to the collection in the museum of which I have charge, I have most carefully compared it with the type ♀ specimen of S. columbia. I am bound to state that I cannot find any difference except the rosy color of Gloveri, and there are no charactcrs which I consider of value to separate the two species. I freely admit that the examination, however carefully made, of only two specimens, both of which are old and in poor condition, is scarcely sufficient to determine this point, but I wish to draw the attention of students who may have a larger amount of material for comparison, to the facts states, with the hope that the true relationship of these insects may be determined.
