This genus was established by Harris 

 on two species of which one {curtipen- 

 nis) belongs to Stenobothrns (Fischer, 

 1853), the other {conspei-sn) must 

 receive this name. Chrysochraon 

 (Fischer, 1S53) is closely related, es- 

 pecially Ch. dispar of Europe, but if 

 but one name can be retained that must 

 be Chloealtis which has twelve years 

 prioritv. In Brunner's Revision this 

 generic title is evidently applied to the 

 species hitherto known as Ch. viridis; 

 here treateti under the title of Dichro- 

 711 or p ha.

Stenobothrus melanopleitrjis. Scud- 

 der, 456. 



This species is readily recognized 

 by the absence of foveolae, the shining 

 black sides of the pronotum of the 

 male, and the peculiar form of the 

 ovipositor of the female. The male 

 differs so much in size and appearance 

 fi'om the female that it was described 

 as a Stenobothrus (iiielanopleurus) by 

 Scudder. The ^ varies from pale 

 straw to dark brown, but b usually 

 light brown above, and the tegmina 

 immaculate, sometimes with verv faint 

 dusky spots; the hind tibiae are either 

 red or yellowish. The ? varies from 

 straw to very dark fuscous brown, and 

 usually has the tegmina more or less 

 spotted with dusky, though they are 

 sometimes immaculate. The name 

 abortiva Harris does not seem worthy 

 of retention, far the larger number of 

 specimens being intermediate in mark- 

 ings. 



About 350 specimens, nearly' one- 

 half of which are females, give the 

 following measurements:

The wings in the male are Lisually 

 one-third to one-half, in the female one- 

 half to two-thirds, as long as the teg- 

 i.iina. In the female the abdomen
