covered above and below with coarse punctures, except on the posterior edge, 

 while the wing covers, head and thorax above are impressed with irregular 

 strife. 



" On the 29th of August several larvae were found in the Depart- 

 ment grounds on the locust (Roblnia pseudacacia), drawing the leaves 

 together, the side of one to that of the other. The larvas transformed 

 to pupse between the 5th and 8th of September, and emerged in the 

 following May. The pupa was spun up in a tough silken cocoon on 

 the surface of the ground, to which earth and fragments of dried 

 leaves and grass were adhering." 



Mr. Beutenmiiller has also raised the larva on locust, and from 

 him I have obtained the following description, which gives some 

 additional items : 



" Head jet-black, shining, cervical shield black shining ; body pale green, with 

 about four or five long stripes darker than the ground color. At the side there 

 are rows of minute piliferous spots each bearing a light browu hair; underside 

 of body as iibove ; the first segment dull black. Length 15 mm. Larva taken 

 June 15th, imago emerged July 8th. The segments of the body gradually de- 

 crease in size towards the posterior part of the body. 



" Prof. Forbes, of Illinois, writes me he has taken the insect at 

 Urbana, Ohio, from May 10-23 at electric light ; August 3d at 

 ' sugar,' and that he bred the insect from Wistaria, the larva being 

 taken July 13th, the imago emerging August 5th."
