THe eggs of this insect were found on a small branch of golden willow in Beverly, Mass., March 14, 1900, in a nursery, close to fruit stock of various kinds. The mass, consisting of 220 eggs, was kept at the temperature of the laboratory, which was considerably higher than that outside. Notwithstanding this fact, none of the eggs hatched till April 23, within forty-eight hours of which time, however, all the larvæ had emerged.

Egg (Plate 4, Figs. 1 and 3).—Eggs placed close together in regular rows, forming a compact mass, in this case about twice as long as broad and in one layer. Egg about .6 mm, long and .45 mm, broad at top, which is nearly flat. Just inside the rounded edge of the top a brown ring encloses an area bright steely gray in colour, and containing a small brown depression in its centre; lateral surface of egg and rounded edge steely gray.

Prof. Smith's remarks in the May Canadian Entomologist contain two separate counts. He implies that I might be led by personal views to an improper treatment of the collection in my charge. This implication I indignantly repudiate, and leave Prof. Smith to explain his breach of etiquette as best he may. While Prof. Smith's lack of humour has led him to misunderstand my views, he has no right to imply that with any personal views whatever I would not properly conserve the National Collection. This collection, rapidly becoming the finest in the country, will continue to be conserved with the greatest care. As to the synonymy of the Acronyctas, Prof. Smith makes two assumptions. First, that the specimens now in the British Museum labeled as Guendée's types are still as labeled and described by him; second, that if so, they are properly types. As to the first assumption, I am not in a position at present to dispute it, though I think that some admixture or confusion might have easily arisen in transference, and considering the length of time that has passed. As to the second assumption, I regard it as debatable in the cases where Guenée described larvæ.

Lycœna amyntula, var. Herrii, n. var.— ♀ expanse, 1.25 in.; differs from typical amyntula by the replacement of the dark area of the primaries by a narrow black band about 1 mm. wide, and on the secondaries by only two red crescents instead of five as in typical amyntula. On the under side the markings are all much heavier.

♂ expanse, 1.00 in.; differs from ♂ of typical amyntula in having a black margin about 1 mm. wide, whereas there is none in typical amyntula, or, if any, a very slight trace. On the under side the markings are much more heavy. The male of this variety is also much smaller than the male of typical amyntula, and the tails seem more distinct in this variety.

Ripersia, Sign.

Ripersia lasii, Ckll, 1896. (Native.) Originally described from ant-nests in Mass.; was found in an ants' nest (Lasius Americanus, Em.) at Toronto, Canada, in 1897, by Mr. R. J. Crew. It has been found infesting the roots of China asters in Mass.

Bib.—Can. Ent., xxxi. (1899), 110.

Dactylopius, Costa.

Dactylopius longispinus, Targ. (Introduced.) The greenhouse Mealy bug, fouud throughout the civilized world, occurs in Canada in all the Provinces where greenhouse plants are grown; it is recorded from South Quebec.

In the summer of 1897 I devoted several weeks to a rapid Orthopterological reconnaissance of the Pacific Coast, collecting material at various points from Yuma to Victoria, B. C., and the following paper is based upon the specimens secured at that time. At the request of Mr. Scudder, to whose collection and mine the types belong, I have studied the material, with the results given below.

So far as I am aware, no species of this group has hitherto been recorded from west of the Rocky Monntains, although it is exceedingly improbable that specimens are not to be found in entomological collections from that region. In the following paper, four well-defined species are noted, one of them extending entirely across the continent. Two others are of especial interest, from the great variation presented by them according to locality, and students of the group will do well to collect material in considerable series.

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.

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.

Orthezia lasiorum, n. sp.—♀. About 2 millim, long; pale orange; ovisac (in specimens seen) not very long; two very long median white caudal lamellœ, about two-thirds length of body, curving over ovisac, but not attached to it. Dorsum covered with waxy secretion, but it is so easily deciduous that I have never found an adult with it sufficiently in place to describe. Middle leg with femur + trochanter 300 μ, tibia 240, tarsus (without claw) 180. Antennæ 7-jointed, the last joint with a terminal spine; joints measuring in μ: (1.)75–90. (2.)72–75.(3.)84–95. (4.)60. (5.)48.(6.)45.(7.)120–129. I have never found one with 8 joints, though I should expect such to occur.
