Termitophilous Sta2ohyl'inidcB. 387 



between the bases of the antennge; surface throughout shining, almost 

 glabrous and impunctate; antennae about as long as the head, prothorax 

 and elytra combined. Prothorax slightly wider than long; base and 

 apex subequal, subtruncate; sides nearly parallel, broadly, feebly ar- 

 cuate, sinuate at apical two-fifths when viewed laterally; surface mod- 

 erately convex, shining, excessively finely and feebly subreticulate, and 

 covered sparsely with extremely short fine setee, having three feeble im- 

 pressions arranged transversely near the middle of the disk, the lateral 

 prolonged slightly behind; surface also feebly impressed toward the 

 middle in front of the basal margin; disk with a few coarse erect setae. 

 Scutellum large, prominent, elevated above the elytra, rough, finely 

 setose. Elytra connate, slightly narrower than the prothorax; sides 

 nearly straight, very slightly divergent from base to apex; the latter 

 broadly, roundly emarginate throughout the width; disk three-fourths 

 as long the prothorax, flat, polished, glabrous, impunctate, convex at 

 the sides, slightly setose and rough on the basal slope, also roughened on 

 the vertical flanks which are not beaded beneath. Abdomen nearly 

 three times as wide as the elytra, widest in the middle; sides strongly 

 arcuate; chitinous surfaces coarsely reticulate, shining, sparsely and 

 coarsely setose. Under surface sparsely setose. Length 2.7 mm. (con- 

 tracted). 



Colombia (Panama 1). 



The abdomen consists of the normal number of segments — 

 six, besides the small terminal segment. The labrum is sep- 

 arated from the anterior margin of the front by a short bond 

 of membrane. 



The sexual characters cannot be determined from the single 

 specimen above described, which is probably a female. There 

 are four specimens known,, one of which is in the Museum of 

 Comparative Zoology at Cambridge, Mass,, and two still in tha 

 possession of Mr. Dudley.
