TRICHESTEMA, new genus 



Agrees with the above description of THchocryptus Thomson ex- 

 cept as follows : Malar space shorter than basal width of mandible ; 

 antennae in female only slightly thickened toward apex, first and 

 second flagellar joints equal in length; propodeal spiracle long, 

 slit-like; areolet with intercubiti strongly convergent above, radial 

 cell long; abdomen in female lanceolate, the apical segments long. 



Pig. 1. — Tkichestema helcostizoides Cushman. Dkawn feom type 



The long apical abdominal segments, and short, thick first tergite 

 give this genus a habitus strongly reminiscent of Hetcostizus 

 Foerster. 



The velvety pubescence probably indicates an association with 

 water. 



Geruotyfe.' — Trichestema helcostizoides Cushman, new species.

Femnl^. — Length 11 mm. ; antennae 4.5 mm. ; ovipositor 3 mm.
