120 THE BLATTIDAE OF PANAMA 



marginal area bounding the sutural margin in the anal field, these 

 areas opaque, blackish. The insect is blackish, with caudal margin 

 of pronotum narrowly ochraceous-tawny, this expanding slightly 

 toward the latero-caudal angles. The cerci and a broad meso- 

 distal annulus on the antennae are ochraceous-buff.

Both females here recorded have fully developed tegmina, ex- 

 tending well beyond the apex of the abdomen. A small series be- 

 fore us shows that tegminal reduction occurs in this species in both 

 sexes, varying to the condition figured for the type, which shows the 

 tegmina failing to reach the apex of the abdomen by almost the 

 pronotal length. 



The present minute brown species has the sexes similar; eyes 

 very widely separated, the interocular width decidedly greater than 

 that between the antennal sockets, eyes reduced and narrower in 

 dorsal than in lateral portion; disk of pronotum flat, strongly trun- 

 catecaudad, with a transverse broadlyobtuse-angulate linear sulcus 

 meso-cephalad, from the angle of which extends caudad a medio- 

 longitudinal linear sulcus; tegmina with numerous, strongly oblique 

 discoidal sectors, and cephalic and caudal femora of male enlarged, 

 the cephalic femora with two large, heavy dentate projections on 

 their ventro-caudal margins. In both sexes the ventro-cephalic 

 margin of the cephalic femora is supplied with a fringe of micro- 

 scopic hairs, of which all but the more proximal are very short. 

 Both median and caudal femora are normally supplied with a 

 minute and very delicate dorsal genicular spine. ^^^ Pulvilli and 

 arolia absent. These features we consider of generic diagnostic 

 value.

^'" Two specimens, in the small scries before us, have one limb showing no trace of this 

 spine.
