long slender scales on the vertex, extending forward as a long tuft; antenne brown, 
verticels and pubescence white, basal joint brown but not so dark as the cephalic 
scales; palpi dark brown the ultimate joint white, except, a very narrow brown 
basal band extending as a tiny brown band on the apex of the penultimate, a broad 
white band on the base of the penultimate and the apex of the following joint, the 
remainder of the organ dark brown, except a very narrow white band, at the pre- 
ceding joint, very heavily scaled at the base; proboscis light scaled on the apical 
half, often not noticeable from the dorsal aspect, and always more marked on the 
ventral side, the proximal half dark brown, very heavily scaled at the base; clypeus 
dark brown; eyes dark brown. 
Thorax: prothoracic lobes dark, with brown cheetz; mesonotum has the median 
third of a light brown, sometimes almost yellowish, covered with the fine tomentum 
so often found on Anophelines, and sparsely with golden brown hair-like scales, a 
well marked dark median line broadening so as to cover the “bare space,”’ and in

third, also extending on the first is well interior to a line through the base of the 
fork of the fifth long vein, and the last is a tiny spot between this and the root of 
the wing. The wing field has many small spots the third long vein is mostly light,
