And Coquebert's figure exhibits, " sufficiently to swear by," the pecu- 

 liar clouding of its wings. Of this species I have seen three specimens, 

 all females, and each agreeing with the above description and figure. 

 They are in the respective cabinets of Mr. Haworth, Mr. Stephens, (taken 

 near Hertford,) and Mr. Bainbridge, who swept his specimen into a net 

 from clover, at Darent, at the latter end of May, 1827. The size varies 

 a little in these three specimens ; it is represented in the plate by the 

 crossed lines under the insect. The following are more ample specific 

 characters. 



Diplolepis depressa, Fabr., Coq., $ . 

 Tab. II. fig. 1. $ . 



Head and thorax rich coppery-aureous and thickly punctured; eyes and 

 ocelli dark brown ; basal joint of the antennae fuscous, the remaining 

 joints ferruginous, except the last, which is dark brown; postscutel shin- 

 ing, impunctate ; the fore legs and intermediate femora ferruginous, the 

 posterior legs and intermediate tibise and tarsi fuscous. The first five 

 segments of the abdomen are of a dark, shining, cyaneous green, the re- 

 maining three tinged with dark coppery green. Wings pale hyaline, the 

 posterior half of the upper pair stained with brown, growing paler to the 

 tips, having a large white spot at the anterior margin, and a whitish fascia 

 in the pale fuscous cloud, near to and running nearly parallel with the tip 

 of the wing. Th^e under side of the thorax and of the posterior thighs 

 is golden green. 



From this species, therefore, we must now draw our generic characters; 

 but before I do so it will be necessary to state that I am unacquainted 

 with its male. It is also necessary to state that I have not included 

 amongst the generic characters any account of the Trophi. This I 

 have avoided for three reasons; 1st. my want of specimens for dis- 

 section ; 2d. the difficulty of the examination of the Trophi, arising from 

 their minuteness, and the consequent superiority of external characters; 

 and 3rdly. from a conviction that as the perfect insects throughout the 

 different groups in the family appear to make but little use of their
