THE CANADIAN ENTOMOLOGIST. 137 



Valve of the male rather large, rounded. Plates long-triangular, 

 exceeding the pygofers, rounded at apex and armed with a few tawny- 

 marginal bristles. Last ventral segment of the female longer than the 

 penultimate, feebly concavely arcuated either side, the lateral angles quite 

 strongly produced, subacute ; pygofers short and thick, blunt at apex and 

 armed there with a kw feeble bristles, a little surpassed by the oviduct- 

 Iowa, Kansas and Colorado. Described from one female and two 

 male examples. The Kansan specimen was captured at Madison, by 

 M. C. Van Duzee. That from Iowa I owe to the kindness of Prof. 

 Herbert Osborn, and the example from Colorado is from Prof C P. 

 Gillette. Prof Osborn's specimen came labelled Conogonus gagates, 

 Ashm., and in the National Museum is an example labelled Scleroracus 

 anthracinus, Uhler. I have adopted Mr. Uhler's specific name as very 

 appropriate for this deep black little Jassid, but I can find no characters 

 to separate it generically from Athysanus. Its highly polished semi- 

 coriaceous elytra are peculiar, but hardly constitute a generic character. 

 This insect superficially resembles Goniagtiathus Falmeri, but they are 

 very distinct.
