Forested region North of Lake Superior, Canada. 

 White Eiver, Ontario, June 35, 1907 (F. Knab). 

 We possess only a single specimen of this distinct species.

Obioinal Descbiption of Culex pullatus: 



?. — ^Near punctor and impiger, but the bristles of the scutellum are chiefly black 

 instead of yellow, etc. Black, the halteres and femora largely yellowish. Scales of 

 palpi black, those on the occiput pale yellow, the upright ones in the middle yellow; 

 those on the sides and the bristles black. Scales of the mesonotum golden yellow, 

 the sides with a few lighter colored ones, the bristles and those of the scutellum 

 chiefly black. Scales of abdomen black and with a tinge of violet, a crossband of 

 whitish ones at base of each segment, dilated at each end, scales of venter whitish, 

 a few black ones in hind angles of the segments. Scales of coxae and on lower part 

 of anterior, and posterior sides of the femora yellowish white, on upper part of 

 femora and toward their apices chiefly black; scales of tibiae blackish and mixed 

 with a few yellowish ones, those on the tarsi blackish; all tarsal claws toothed. 

 Wings hyaline, the scales brown, lateral scales of the veins narrow and almost 

 linear, petiole of first submarginal cell nearly as long as this cell, hind cross-vein 

 about its length from the small. Length 4.5 mm. 



c?. — ^Palpi slender, the scales and hairs black, the latter, like those of the antennae, 

 appear whitish in certain lights; proboscis reaching slightly beyond apex of palpi. 

 Mesonotum with a pair of subdorsal bare vittae on its anterior two-thirds. Abdomen 

 with a cross-band on the apices of ventral segments 3 to 7. Petiole of the first sub- 

 marginal cell longer than the cell. Otherwise as in the female. 



Kaslo, British Columbia. One female and ten males bred from the larvae, June 

 8 to 16, by Dr. H. G. Dyar; also ninety females and thirty -three males bred from the 

 pupae, or captured, by Dr. Dyar. 



Type. — No. 8030, U. S. National Museum. 



Although so similar to punctor and impiger in the adult state, the larva is very 

 different, as Dr. Dyar has pointed out to me. 



Descbiption of Female, Male, and Laeva of Aedes pullatus : 



Female. — Proboscis rather long and slender, subeylindrical, uniform ; labellae 

 conically tapered; vestiture brown; setse minute, curved, black, those on the 

 labellse more prominently outstanding. Palpi short, about one-fifth as long as 

 proboscis; vestiture black; setse moderate, bristly, black. Antennae with the 

 joints subequal, rugose, pilose, black, the second somewhat enlarged ; tori small, 

 subspherical, with a cup-shaped apical excavation, ferruginous, with a patch of 

 small white scales on inner side; hairs of whorls rather short, sparse, black. 

 Clypeus short, roundedly triangular, nude, black. Eyes black. Occiput black, 

 broadly clothed with narrow, curved, dull ochreous scales on vertex, broad flat 

 paler ones on the sides, without black lateral patch, many erect, forked, pale 

 yellowish scales on the nape ; setas along margins of eyes black, those projecting 

 forward at the vertex pale. 



Prothoracic lobes elliptical, remote dorsally, black, clothed with broad, curved, 

 whitish scales and black bristles. Mesonotum black, clothed with narrow, curved, 

 pale ochreous-brown scales shading paler towards sides and about antescutellar 

 space, a pair of ill-defined, submedian, narrow, darker longitudinal stripes, a
