132 THE CANADIAN ENTOMOLOGIST. 



Abdomen brown, covered with brown scales, and narrow white basal 

 bands on most of the segments, lacking on the first and last three segments, 

 which latter, however, have narrow lateral white spots, the continuation of 

 the ventral marking. The ventral marking is rather 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 antepenul- 

 timate, running sharply laterad and then caudad, 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, on the cephalic aspect; metatarsi and first tarsal joint basally light 

 banded, second, third and fourth joints 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, metatarsi and 

 ist tarsal joints have white basal bands, the rest of the tarsi 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 ; metatarsi and first and second tarsal joints with heavy basal white 

 bands, the last two joints pure white. The ungues on fore and mid legs, 

 though equal and simple, are much heavier than are usually found on any 

 mosquito of this size, the hind ones markedly smaller, but, having only one 

 specimen, I have not dissected it, so that while fairly sure that it belongs 

 to Anhocheleomyia, Theobald, it is impossible to state definitely the 

 peculiar shape of the ungues. It is, I think, quite certain, however, in 

 spite of the flat scales on head and scutellum, it is not a Stegomyia. 



Wings clear, brown scaled, the scales very large, and of the Taenio- 

 rliynchus type, but a little inclined to asymmetry ; cells short ; ist sub- 

 marginal cell nearly a half longer and a little narrower than the 2nd 

 .posterior, the stem of the former about a third shorter than that of the 

 latter; supernumerary and mid cross-veins equal and meet, posterior 

 cross-vein also about the same lengLJi, and distant from the mid a little 

 more than twice its own length ; halteres light stem, with dark knob. 



Length, 2.5 mm.
