Culex (Choeroporpa) bastagarius Dyar, Ins. Ins. Mens., vi, 105, 

 1918. 



Clasp-filament rather narrowly snout-shaped, the spine 

 widened and appendiculate. Outer division of lobe of side- 

 piece short, with a short stout inner arm, bearing a long filament 

 with hooked tip and a small filament ; middle filament broadly 

 blade-like; two outer filaments and a small oval leaf, the leaf 

 having a very large insertion, although small. Inner division 

 of lobe single, forming a broad common pedicel, one filament 

 inserted basally of the other, long, strong, with widened 

 pointed tips. Second uncal plate widely furcate, both limbs 

 short and pointed ; a stout horn with them, making a three- 

 pointed tip. First plate with a horn-like projection at insertion 

 of articulated plate. Articulated plate triangularly widened, 

 broadly emarginate at tip. Basal hooks very short, stout, 

 curved, with bluntly pointed tips. Basal appendages moderate, 

 elliptical, approximate, setose, with rather long hairs. 



From Trinidad. 



Culex (Choeroporpa) vapulans, new species. 



Genitalic characters indistinguishable from bastagarius, ex- 

 cept that the basal hooks are rather long, recurving to the 

 middle of stem of second plate, with strongly hooked tips. 



The adult does not differ from the description of bastagarius.
