beyond the tip of Ri+s; prefurca of the media nearly as long 

 as the first section of the radial sector. Mexico, Teapa in 

 Tabasco. 



In Williston's figure the palpi appear incurved, this, how- 

 ever, may be the engraver's error. I have a specimen from 

 Pottstown, Pa. (collected by C. W. Johnson) in which the face 

 and palpi are yellow ; the coalesced part of the media is but lit- 

 tle more than half as long as the petiole ; and each claw has a 

 tooth near the base.
