[Vol. 93 
mesopleural carina; forewing (fig. 5) with long slender stigma + Rl, 
RS extended by evenly curved streak, medial vein arises before cu-a; 
metanotum 0.9X as long as scutellum, medial enclosure punctate, 
differently sculptured from lateral area; propodeum with short dor- 
sal surface, abruptly declivous posteriorly, lateral angles short and 
blunt; hindcoxa with dorsobasal carina; terga sharp-edged laterally, 
covered with dense small punctures; tarsal claw with large perpen- 
dicular submedial tooth. 
Type: Bupon pasohanus Kimsey. 
Etymology. Bu - great, pons - bridge (Latin, masculine). 
Discussion. The most unusual diagnostic feature of Bupon is 
the strongly projecting transverse frontal carina. The only other 
amisegine genus with any indication of such a carina is Perissosega 
where it is faint by comparison. In other respects Bupon more 
closely resembles Cladobethylus, based on the lack of most of the 
derived characteristics found in the Amiseginae. Two derived char- 
acteristics that are found in Bupon and will immediately distinguish 
this group are the transverse facial carina and the short, relatively 
broad male flagellum.
