Phyciodes mylitta. Edw.

Egg.—Not observed; but laid about 50 together.

Frist Stage.—Head shining black; width .25mm. Body cylindrical; cervical shield and anal plate black; fine black hairs, slightly curving forward, arise from minute black elevated spots.

Second Stage.—Head black and shiny; width .40mm. The body is covered with rows of conical elongated tubercles, each with many bristly hairs, arranged as in the mature larva. Sordid greenish, shaded with black dorsally, the cervical shield, anal plate and tubercles black.

Eggs.—Laid in a mass, probably under the bark of the food-plant, for which purpose the long ovipositor of the ♀ moth seems fitted; the winter is probably passed in this state. Spherical, but some what misshapen from being closely pressed together; smooth, slightly shiny, under the microscope appearing irregularly indented; colour, yellow, becoming later reddish; diameter, .5mm.

Meigenia websteri, n. sp.

Female.—Head a little wider than thorax and abdomen. Eyes brown, very sparsely hairy; front and face not quite one half the width of head; front a little prominent; frontal vitta about one-fourth the width of front, brown, lighter behind where it splits on each side of the ocelli; frontal bristles in a single row, descending a little below base of third antennal joint, some fine hairs on sides of front outside them; two orbital bristles; sides of front with a slightly brassy tinge; sides of face moderately wide; a little less than one-half the width of the facial depression, silvery, bare; face slightly receding, facial depression silvery, facial ridges cliliate to a little below base of third antennal joint; cheeks moderately wide, cinereous, hairy, with bristles on lower border; vibrissæ inserted at a little distance above the oral margin; antennæ not as long as the face, blackish, third joint slightly reddish at base; second joint not elongate, bristly; third joint not widened, more than three times as long as the second; arista black, microscpically pubescent, thickened more than half its length, three-jointed, the second joint hardly elongate; proboscis, brown, fleshy, not so long as height of head, labella well developed, palpi well developed flavous club-shaped, thickened and curved at the tip, black bristly; occiput cinereous, gray hairy below, with fringe of black hairs on orbital margins.

The Dysderidœ is a small family of spiders occupying in a certain respect an intermediate postion between the Tetrapneumones and the Dipneumones; the openings to the tracheæ are just behind the lung-slits, so that they may appear to have four lungs. The eyes are six in all of our forms. The mandibles are not small, in Dysdera quite large. The male palpi are quite simple in structure.

The Entomological Club has reason to congratulate itself upon the favourable conditions under which it meets. We are here in our national capital, a city in which every American feels a pride, and the beauty of which can but favour our enjoyment. We are in the centre of entomological activity for the United States—and I am tempted to say for the world, for I believe we should have to make diligent search to find any community where so many skilfull entomologists are devoting their entire time to entomological problems.
