2. Bothromus gibbus, new species 



Front wing 5.0 to 5.5 mm. long; first tergite in profile strongly 

 convex, about 2.0 as long as high, the area between its lateral longi- 

 tudinal carina and ventral edge of uniform width beyond spiracle, 

 subapically about 1.1 as wide as the width of middle tibia; second 

 tergite rather strongly convex, with close rather coarse punctures, its 

 median pair of carinae extending 0.75 its length in male, extending 

 0.4 to 0.55 its length in female; seventh tergite moderately retracted. 



Black. Palpi of male, spot on under side of scape of male, tegula, 

 subtegular ridge, and spurs of middle and hind tibiae whitish; fla- 

 gellum blackish brown, paler beneath (especially in male); palpi of
