THE CANADIAN ENTOMOLOGIST. 55 



Appearance of the larva fresh, from the egg. — Length one twelfth of an 

 inch. Head black with a few short whitish hairs, some of them rather thick 

 and fleshy looking. Body dull yellowish brown, with longitudinal rows of 

 hairs, similar to those on the head ; those on the second segment and imme- 

 diately behind the head, longer than the others. Hairs on body very short, 

 whitish, semi-transparent, thick, some of them more like short tubercles than 

 hairs. The descriptions of larvaî of this age, as well as of the eggs, were all 

 taken under a magnifying power of forty-five diameters. 



Appearance when more than half grown. — Length five eighths of an inch. 

 Head dark green, slightly downy with minute hairs. Body of the same 

 color, with the same downy look, occasioned by a great number of thickly 

 set short hairs. The body is also dotted with points of a slightly paler hue. 

 A yellowish white stripe on each side close to under surface. Beneath 

 slightly paler than above, feet and prolegs of the same color. 



The full grown larva difi"ers from the foregoing only in size, being about 

 one inch long, and in having an irregular streak of bright red, running 

 through the whitish stripe close to under surface. 



My specimens were fed on clover. I have since found this larva feeding 

 on the wild lupin (JjU])inus perennis) and also on the cultivated pea. It is 

 not unlike a sawfly larva in form and action, feeding on the upper surface of 

 the leaves and twisting its body into a coil when disturbed. 



Pupa. — Length seven tenths of an inch, girt with a silken thread across 

 the middle ; greatest diameter about the sixth segment. Head case pointed, 

 with a purplish red line on each side, running to the tip and margined behind 

 with yellow. Body pale green, with a yellowish tinge and a ventral line of 

 a darker shade, formed by a succession of minute yellowish dots — a yellowish 

 stripe along the sides of the five hinder segments. Beneath on the seventh, 

 eighth and ninth segments, is a blackish brown line on each side, deepening 

 in color about the middle of each segment, and a dorsal line of dark green 

 about the same length. 



On the eighth day the color of the wings began to show underneath, the 

 pink fringe prominent and the discal dots visible, and on the ninth and tenth 

 days the imago appeared. 



Argijnni& myrina. — A female specimen, somewhat beaten, was captured 

 on the 20th of June,.and confined in a large pill box. One egg was deposited 

 on the 22nd or 23rd, and five more on the 24th, all attached to the sides 

 and bottom of the box. The eggs were pale green, elongated, in shape some- 

 thing like an acorn, base smooth and convex, circumference striated longi- 

 tudinally, with about fourteen raised striae, which were linear and smooth, 

 spaces between, about three times wider than the striae — depressed, concave 

 in the middle, and ribbed by a number of cross lines, fifteen to twenty be-
