SILVERIA HEXHEX Dyar 



Figure 45 



Silveria hexliex Dyar, Ins. Ins. Mens., vol. 13, 1925, p. 11. 



The male and female types are before us from the type locality; 

 no other specimens. The species is readily distinguishable from 

 chiriquitensis by the black irrorations lying along the veins. 



Expanse. — Male, 14 mm. ; female, 18 mm. 



In the female the genitalia are distinguished from those of chiri- 

 quitensis by their differently shaped (narrower and straighter) 

 ductus bursae. Unfortunately the abdomen of the type of hexhex 

 was damaged and the genitalia missing so no comparison could be 

 made with the male genitalia of chiriquitensis. 



Female genitalia figured from paratype. 



Life history unknown. 



Type. — In National Collection. 



Type locality. — Colima, Mexico.

 Hind wing with veins 4 and 5 approximate at origin but divergent ; 

 6 from apex of cell with 7, which anastomoses rather shortly with 8.
