We have received no specimens of Anopheles hellator since the original types 

 It is probably more widely spread, but, as it is not taken unless bred and occurs 

 in such unusual situations, it is seldom collected. It represents in northern 

 South America the widely distributed Anoplieles holivieibsis Theobald.

 subspherical, with a cup-shaped apical excavation, deep brown, pruinose. Clyp- 

 eus prominent, subtriangular, blackish, nude. Eyes black. Occiput densely

 tween eyes, a row of long black hairs along margins of eyes. 



Prothoracic lobes small, lateral. Mesonotum narrow, elongate, gray pruinose,
