We have received no specimens of Anopheles bellator 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 Anopheles holiviensis Theobald.

Descbiption op Female and Larva of Anopheles neivai (Male Unknown) : 



Female. — Proboscis moderate, straight, slightly enlarged basally; labellae 

 long, lanceolate, with fine outstanding setae ; vestiture black. Palpi as long as 

 the proboscis, roughened by long erect spatulate black scales, a few whitish 

 scales at apices of last two joints. Antennae filiform, the joints subequal, rather 

 short, blackish, densely pilose ; hairs of whorls rather short, sparse, black ; tori 

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

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

 clothed with erect spatulate black scales and a few scattered white ones, densest 

 in front on the median line, a tuft of long white hairs projecting forward be- 

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



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

 with four longitudinal brownish-black stripes, two of them narrower and rather 

 closely approximated mesially terminate at antescutellar space, the others
