By June 2ist the amatrix and concumbcns larvae were dy- 

 ing fast and not a single one of the larvae of either, handled by 

 the senior author ever pupated. The eggs of rclicta, amatrix, 

 and concumbcns hatched slowly, a few a day for weeks, it 

 seemed, and the larvae were just as slow to develop. All three 

 of these were fed on black willow. 



Another larva of amatrLv after fourth moult, was gray with 

 a faint reddish tint. Tubercles, red. True legs, flesh color, 

 also pro-legs. Head flat as in cara and with strong black 

 dashes from mouth to lobe above but not across the top. Head, 

 gray in front with pale reddish lobes above. A brownish band 

 crosses the 5th abdominal segment. The hun.p is small and pink- 

 ish but not including the lateral tubercles, in fact, the hump is 

 scarcely larger than a tubercle. Sho-t lateral fringe. Ventral 

 surface paler at^ front than above and with strong black spots 

 in brownish yeL^w. A handsome larva. 



A peculiarly banded larva of amatrLv found by the junior 

 author on the i6th of July on blue willow was two and a half 

 inches long, very light gray with four lateral, rather narrow 

 longitudinal dark, almost black bands, two to the side, the light 

 gray appearing as broader bands. Head concolorous with the 

 body and with a strong lateral black dash. Head, as in cara, 

 but with small gray spots or low tubercles at the upper lobes. 

 Body dots dark. Tubercles, white. The hump over the 5th 

 abdominal segment not otherwise than the body color. The 

 strong tubercles over the 8th abdominal segment, dark gray. 

 True legs and pro-legs, light gray as body. On the back half 

 of each body segment, the dark bands become black. Ventral 

 side of the body pinkish with black central spots. By compar- 

 ing this description with the one of the grown larva of Amatrix 

 in our last year's article, a great difference in color will be 

 found. Two of these striped larvae were found by the junior 

 author, but the one sent to the senior author had succumbed to 

 six fat, parasitic dipterous larvae, larger than the full grown 

 maggots of the common house fly. The other larva gave the 

 junior author a chrysalis and an amatri.r moth in due time. 

 We had hoped it might be something else. After all, there is 

 much variation in the larva of this species. It is somewhat
