Found in some numbers by myself in the “tierra caliente” of Chiriqui. In both 
sexes of this species the connexival segments are angularly dilated at their outer apical 
angles, the fifth being widened into a triangular plate. The males have the abdomen 
much narrower than the females and subparallel, with the apex abruptly truncate, the 
fifth segment dilated laterally into a very prominent triangular plate. The type ( @ ) 
has been communicated by Dr. Aurivillius.

‘I'wo males and two females from Chiriqui are referred to this species, the type ( ¢ ) 
of which is before me. The males have the abdomen subparallel, with the outer 
apical angles of each segment angularly dilated, the fifth widened into a triangular 
laterally projecting plate, the sixth also triangular and projecting posteriorly. In the 
females the abdomen is broader and rounded at the sides, with the fourth segment 
wider than the fifth. ‘The basal joint of the antenne is about as long as the head, and 
a little longer than tne third joint. The type is dirty and somewhat abraded, our 
specimens showing the coarse, short, curled hairs much more distinctly above and 
beneath.
