The larva when full grown is subcylindrical in form, abdominal seg- 

 ments 2 to 7 subequal in width, the others gradually narrowing toward the 

 extremities. (".round color either olive or green, variegated with red, 

 forming with a dark green mediodorsal and two submedial stripes, seven 

 longitudinal stripes of alternate green and red. Sometimes red and 

 sometimes green is the prevailing tint. Surface finely granulate, feebly 

 shinine. Aside from color the treneral characters are much the same as 

 in D. X a n t h o m e 1 ae n a Dalm. . . Each segment is produced into a 

 transverse row of lo papillae, each surmounted by a small black piliferous 

 wart, and terminating in a fine liristle. The first thoracic segment has an 

 additional row of papillae, and each spiracle is surrounded by a ring of black. 

 Head small, nearly circular, color shining l>lack or very dark brown, triangu- 

 lar space in middle antl cl)'peus brown. The |josterior end of the body termi- 

 nates in a proleg which is concoloroiis with the surrountling portions of the 

 terminal segment. This is surrounded with two rows of black bristles, one 

 above and the other below. Legs considerably darker than the neighboring 

 portions; sutures and some other portions marked with black, last joint 

 nearly black. Length lo mm, witlth 3 mm. 



From the variability in color of the larva we would expect a similar 



variation in the pupa. As with the larva there are two [jrevalent ground 



tints; in one, rose is the prevailing color; in the other, somewhat greenish 



orange. Probably these colors ■ represent the similar colors in the larva, 



rose corresponding to red and orange to olive and green. Aside from color 



the pupa of this species closely resembles that of D. x a n t h o m e 1 ae n a. 



The pink or rose-colored form of the pupa has [jearly antennae, elytra, and 



legs, while the orange type has orange-yellow as the color of the same 



parts. Length, 6-6.5 ni'ii, width, 3-3.2 mm.

 willow leaves. 



This species is closely allied to the striped cottonwood beetle, M e 1 a-
