Egg.—Conical, broadly truncated, the flat top covered with a low network of irregular meshes, very fine about the micropyle; the lower part rounded, almost hemispherical; the upper part of side and to about two thirds the distance to base ribbed vertically,—about forty low ribs, with fine transverse lines between them; below the ribs there is an irregular network; color yellow-green. Duration of this stage about 13 days.

1. Grapta Faunus, Edw.

2. Chrysophanus Florus, Edw. (or C. Helloides, Boisd.—uncertain.)

3. C. Epixanthe, Bd.–Lec.

4. Argynnis Atlantis, Edw.

5. Melitea Harrisii, Scud.

6. Phyciodes Tharos, Drury.

7. Colias Interior, Scud.

8. ib. var. Laurentina, Scud.

9. Cœnonympha Inornata, Edw.

On pages 121–122 the generic term Lepisesia is twice written wrongly, “Lipisesia.” To my statement with regard to the food plants of the Smerinthinœ, must be added that several unocellated genera feed on forest trees, such as poplar, linden, oak, etc. I have taken our geminatus on willow; my statement as to fruit trees (Rosaceœ, Caryœ) gives the general food of Cressonia, Calasymbolus, Smerinthus and Paonias. I would likewise add to my remarks as to the sequence of the groups that they seem to me to form two series; the first embracing the Macroglossinœ, Chœrocampinœ and Smerinthinœ; the second the Acherontinœ and Sphinginœ; the members of each series resembling each other more than the members of the opposed series. With regard to my List, p. 126 et seq., I would say that the manuscript was in the main long completed, perhaps nearly a year before I received Prof. Fernald's excellent paper. After receiving it I merely so far corrected and added to my MSS.

For three years past I have reared this species from eggs and young worms, and in no instance have they agreed with descriptions I have met with. Two years ago I had a brood of eight. Three of them had six spots—three on each side—two four spots, one two spots, and two without spots.

Last year I had nine, not one of which had the least semblance of a spot, and were lighter green than those of the year before. This year the brood consisted of seven, two of which were unspotted, one with four, three with two, and one with a single spot.

Lygus monachus, n. sp.

Long oval, pale green or testaceous, coarsely punctate above, sericeous pubescent. Face convex, highly polished, bald; base of vertex with a longitudinal impressed line, towards which a similar line runs obliquely forward each side from the inner corner of the eye; antennæ sparsely and minutely pubescent; basal joint thickest, a little longer than the head, tapering at base; second joint thrice as long as the basal, infuscated, and a little enlarged towards the tip; third and fourth setaceous, both together not as long as the second. Pronotum highly polished, convex, coarsely punctate in transverse wavy lines, each side with a dark brown vitta, or long spot; lateral margins smooth, callous at base, the humeral angles subacute; callosities prominent, convex, almost confluent on the middle; lateral flap of pronotum irregularly punctate. Pectoral pieces pale, impunctate. Legs pale green, feebly pubescent; apex of posterior femur usually with one or two fuscous bands, tip of tarsi and the nails black. Scutellum moderately convex, excavated at base, transversely obselete, punctate, more or less infuscated. Corium coarsely transversely vastrate-punctate, the clavus more or less infuscated, sometimes with all but the margins covered with dark brown; corium usually with a transverse dark brown arc next the posterior border; cuneus long and wide, the incised base fuscous and the inner margin brown; membrane pale testaceous, with two or more dark clouded spots, the inner submargin of the principal areole, a spot at its tip and the base next the cuneus all more or less fuscous. Ventor pale greenish.

This pernicious insect has been very abundant here for many years. As early as 1874 I found it in considerable numbers among moss on dry, grassy hill-sides at Lancaster, N. Y. This season (1886) it was remarkably abundant in a dry upland hay field near the same locality. I have also taken it at Ridgeway, Ont. Ordinarily the short winged form predominates, but in hot, dry summers, such as those of 1881 and 1886, they mostly acquire fully developed membranes. I find on comparison with a lot of perhaps one hundred fully developed examples from Kansas, that ours are quite uniformly larger and more robust, with longer hairs on the pronotum.

*Stylopyga orientalis, Linn. Common in houses; have also taken it under stones in a lane behind a bakery in summer.

Ischnoptera pennsylvanica, De Geer, Not common. I took a specimen under bark of a stump on Montreal Mountain some years since, and on June 4th, 1885, I took three specimens under bark of a stump at Abbotsford, P. Q.

Temnopteryx marginata. Rare. Two specimens taken under bark of a fallen tree on Montreal Mountain.

*Ectobia Germanica, Stephens. Common in houses in the city of Montreal. Has been so to my knowledge for the last fifteen years; how much longer I cannot say.

Again, the genera Citheronia and Eacles are a South American element in our fauna, while the typical Attacinæ, such as Actias, probably belong to the Old World element in our fauna, together with all our Platypteryginœ. Among the Hawk Moths the genera Philampelus and Phlegethontius are of probable South American extraction, though represented now by certain strictly North American species. Mr. Robert Bunker, writing from Rochester, N. Y., records the fact that Philampelus Pandorus, going into chrysaiis Augnst 1, came out Sept. 10 as a moth, showing that in a warmer climate the species would become doublebrooded. And this is undoubtedly the case with many species the farther we go South, where insect activities are not interrupted so long and so strictly by the cold of winter. Since the continuance of the pupal condition is influenced by cold, a diminishing seasonal temperature for ages may have originally affected, if not induced, the transformations of insects as a whole. Butterflies and Moths which are single brooded in the North become double brooded in the South.

Having recently, through the kindness of Mr. W. W. Hill, the well known Lepidopterist, been able to carefully compare my type of hospitalis with a series of Agrotis perconflua Gr., I believe we have to do with a variety of this latter species differing by the black marked t. a. line, the black edging on costal region of t. p. line, the more suffused and deeper color. The insects are structurally identical, and although variation in these points is not usual (I have not met with it), yet the perfect correspondences in other points carry the conviction that in hospitalis from Lewis Co., N. Y., we have only a form of perconflua.
