I have here erected a new genus for their reception under the 

 n a m e Eupa chylo mma. 



The three genera may be separated as follows : 

 First joint of hind tarsi twice as long as the four follow 

 ing joints united 2 



First joint of hind tarsi scarcely one-third longer than 

 the four following joints united, or of an equal length. 

 Second submarginal cell longly petiolated, the radius 



divided into three divisions Pachylomma Breb. 



Second submarginal cell sessile, at the most subsessile, 



the radius divided into two divisions Eupachylomma Ashm., g. n. 



2. Second submarginal cell sessile, the radius divided 



into two divisions Eurypterna Forst.

EUPACHYLOMMA Ashm., gen. nov. 

 (Type Wesmaclia rileyi Ashm.) 



Differs from Pachylomma De Breb. principally in the vena 

 tion of anterior wings, the radius having but two branches, the 

 cubitus being interstitial with the apex of the first branch of 

 radius and strongly curved outwardly from the base, while the 

 second abdominal segment is much longer than the first (the 

 petiole) and the spurs of hind tibia3 are also longer. 



Two species are known to me, separated as follows : 

 Head and thorax black, abdomen piceous, nearly black; 

 clypeus, trophi, two basal joints of antennae, and four 



anterior legs whitish; hind legs yellowish E. rileyi Ashm. 



Head black; thorax, sutuivs of abdomen, and base of 

 fourth segment luteous; rest of abdomen, three stripes 

 on mesonotum, small spot on scutellum, and the meta- 



thorax brown E. flavocincta, sp. n.
