Specimens examined. — I have seen 12 examples in Dr. Cameron's 

 collection and 15 collected by Chapin and Blackwelder in Februaiy 

 1937. 



Remarks. — This species was described as a variety of X. vilis 

 Sharp. The West Indian specimens identified as vUis in the British 

 Museum are quite distinct, but I have not compared specimens of 

 fuscipennis directly with the type of vilis. I believe, however, that it 

 w^ill prove to be a distinct species. Among West Indian species it is 

 distinguished by its elytral coloration and the impunctate antennal 

 grooves. 



Our examples were collected from dung and manure and flying 

 at dusk.

 punctures, especially near apex; ocular grooves absent; with large

 hind; with minute punctulae throughout but without ground
