BRACHYGLUTINI 165 



hirsute, flattened dorso-ventrally when seen from the side, and with a distinct 

 sinuation on the internal face at apical third. 



Pronotum with neither subbasal lateral, nor basal median foveae. 



Each elytron with an obtusely elevated humerus, an entire sutural stria, 

 no trace of a dorsal stria, flank simple, base transversely carinate with four 

 minute basal foveal points just posteriad of the basal transverse carina. 



Abdomen with five visible tergites, only the first two being fully visible 

 from above, the next two more or less vertical and the last ventral in position. 

 Lateral margins narrow, but well-developed on the first three segments. First 

 tergite twice as long as second, with a pair of straight, parallel basal carinae 

 almost half as long as the segment and separated by one-fourth the segmental 

 width. Second a little longer than third; third and fourth subequal in length. 

 Fifth tergite twice as long as fourth, nearly semicircular, tumid, rather coarsely 

 punctate. 



Abdomen with five stemites visible medianly ; first long, one-fourth longer 

 than the next three united, the latter short, subequal in length. First visible with 

 a lateral fovea on each side immediately posterior to the mesial angle of the 

 posterior coxae, and with its orifice directed toward the lateral margin. Fifth 

 visible (last) sternite one-half the length of the first visible sternite, trans- 

 versely tumid, rather coarsely punctate and closely in contact with the apical 

 margin of the fifth tergite. 



Mesosternum very transversely elevated at middle into an angulated cari- 

 noid wing above each middle coxa; mesosternum broadly introduced between 

 the middle coxae as a truncate plate ; middle coxae distant. 



Metasternum slightly longer than first visible ventral, simple, not concave ; 

 produced medianly into a broad, truncate plate between the very distant pos- 

 terior coxae. 



Legs simple. 



Described from a single female specimen, the type, collected by the author 

 on Barro Colorado Island, Gatun Lake, Panama Canal Zone, at a light at night, 

 on July 7, 1936.
