Genus Ficalbia. 577 



peculiar, the proximal segments being mostly white scaled, with only- 

 narrow brown apical bands, but the last three segments are largely brown 

 scaled, a narrow white line starting at the median line of the base of the 

 antepenultimate, running sharply lateral and then caudal, forming the 

 lateral white spots of the three last segments noted above ; apical brown 

 hairs, apparently much more numerous on the antepenultimate segment. 



Legs all brown, with more or less white at the bases; coxae and 

 trochanters testaceous with white scales ; fore femora dark brown, a 

 narrow white line on the ventral side extending from the base to near 

 the apex, where there is a white spot on ventral and lateral aspect, not 

 appearing on the dorsal aspect ; tibiae brown, a very narrow white band 

 a little proximal of the middle or the cephalic aspect; first and second 

 tarsal segments basally light banded, second, third and fourth segments 

 brown ; mid femora light at the base, a distinct white spot about midway, 

 and an indistinct white spot interior to this, both on the cephalic aspect, 

 also a brilliant white spot at the apex ; tibiae brown, with a white band 

 about midway, first and second tarsal segments have white basal bands, 

 rest of tarsals brown ; hind femora brown, white at base and nearly two- 

 thirds its length and apex white (femora therefore mostly white) ; 

 tibiae brown, with median white band; first, second and third tarsal 

 segments with heavy white basal bands, last two segments pure white. 

 Ungues on fore and mid legs, though equal and simple, are much heavier 

 than are usually found in any mosquito of this size, the hind ones 

 markedly smaller. 



Wings clear, brown scaled, scales very large, and of Taeniorhynchus 

 type, but a little inclined to asymmetry ; cells short ; first sub-marginal 

 cell nearly a half longer and a little narrower than the second posterior 

 cell, stem of the former about one-third shorter than that of the latter; 

 supernumerary and mid cross- veins also about the same length, and 

 distant from the mid a little more than twice its own length ; halteres 

 with light stem and dark knob. 



Length. — 2 ' 5 mm. 



Eahitat. — Camp Stotsenberg, Angeles (Miss Ludlow)."
