462 A Monograph of Culicidae. 



pale; in the fore legs the apex of the femora and tibiae are 

 white, in the mid legs there is a basal white band to the first 

 tarsal, and the next two tarsals have very narrow bands ; in 

 the hind legs there is a broad band to all the segments, the 

 hind tarsal being nearly all white ; femora, tibiae and first 

 tarsals spinose ; ungues equal and simple ; the white apices of 

 the femora and tibiae are rather more densely scaled than the 

 rest, so look swollen. 



Wings with the first sub-marginal cell much longer, but very 

 little narrower than the second posterior cell, its base nearer the 

 base of the wing, its stem about one-third the length of the cell, 

 stem of the second posterior about two-thirds the length of the 

 cell ; posterior cross- vein longer than the mid, about one and 

 three-fourths its own length distant from it ; stem and lower 

 branch of the fifth long vein with a double row of rather long 

 median vein scales ; outer border of costa spinose. 



Length. — 2 mm. 



$ . Head as in ? , but with more forked scales ; palpi thin, 

 deep brown, with three white bands, one at the base of the 

 last two segments and a broader one on the ante-penultimate, 

 the last segment shorter than the penultimate, the apical one, 

 bluntly acuminate, ending with a few spines, no lateral hairs, a 

 few long hairs on the penultimate ; proboscis thin, much expanded 

 apically. Antennae plumose. Thorax as in J , but with longer 

 black bristles. The abdomen with basal white bands. Basal 

 segment of the genitalia, with a prominent lateral lobe, with thin 

 long chitinous flat bristles, becoming almost hair-like at the apex 

 and curved ; the claspers rather short and broad, with the lateral 

 terminal segment slightly clavate and passing beyond the apex of 

 the clasper. 



Fore and mid ungues unequal, both uniserrate, the larger 

 with a long curved basal lateral tooth ; hind equal and simple. 



Wings with the scales broader than in the 9 , especially on 

 the apical parts of the veins ; first sub-marginal cell much longer 

 and slightly narrower than the second posterior cell, its base 

 nearer the base of the wing than that of the second posterior cell, 

 its stem less than one-third the length of the cell ; stem of the 

 second posterior cell not quite as long as the cell ; posterior cross- 

 vein not quite twice its own length distant from the mid. 



Length. — 2*5 mm. 



Habitat. — Rio Janeiro (Professor Goeldi). 



Time of capture. — April.
