102 COLEOPTERA. 



ferruginous, instead of five as in aurata (as remarked by 

 Mr. Crotch. 



Mr. Crotch points out that the oedeagus in the male is not 

 emarginate ; but the difference in that respect between the 

 two species appears to be that in aurata the oedeagus is 

 arched, shghtly contracted in the middle, depressed in a 

 trifling degree at the apex, and obtusely rounded; whilst in 

 chloris it is arched, parallel, depressed at the apex, and 

 acutely angled. 



I find in my collection specimens answering to this de- 

 scription ; they are all, besides, more elongate and parallel 

 than C. aurata^ which peculiarity is also remarked by 

 Foudras ; aurata however appears also to be concolorous 

 sometimes. Mr. Waterhouse has long separated similar 

 examples in his collection as possibly distinct, but he informs 

 me they all came off poplars.
