 Monogr. of Culicidae, 11:142 



Male. Length 4.5 to 5 mm. Uniformly fuscous. Palpi as. 

 in plate 44, figure 12. The thorax is apparently marked with 

 stripes; bases of the abdominal segments with yellow scales;, 

 bases of the femora and the tips of the tibiae yellow. Tarsal 

 claws of the fore and middle legs unequal, each with a tooth,, 

 hind claws simple. Male genitalia resemble those shown on 

 plate 43, figure 11; but the apex of the terminal cL'iw is sinuous, 

 and with a tiny hooked appendage. Wings hyaline, with fuscous 

 scales. Venation as in figure 9. Halteres pale. 



Female. Palpi as shown in figure 13, All tarsal claws simple. 

 Venation of the wing as in figure 10. In other respects like the 

 male. 



Described from alcoholic specimens obtained from Professor

Larva. Length 7 to 8mm. The head is round, widest at the 

 eyes, slightly wider than long, with six moderately long hair 

 tufts in a transverse row immediately back of the antennae; the 

 antennae slender, uniform, and brown in color but paler 

 at the base. On the shaft is a tuft of 10 to 12 

 long hairs, a little below the middle, and at the tip 

 are three slender and one stout spine and the stout apical- 

 joint. Rotatory fans normal. The mandibles have immediately 

 above the teeth a long, stout spine with a serrated inner margin. 

 The maxillae possess a pair of moderately long dorsal spines. 

 The cephalic margin of the labium is arcuate, with about 23 

 teeth, besides three on each lateral margin [pi. 44, fig.l]. The 

 epipharynx is of the usual shape, though its lateral spines are 

 somewhat longer than the median [fig.6]. The hypopharynx 

 has a toothed margin and eight spines, four on each side, two 

 lateral lobed processes each with six fingerlike projections and' 

 a median piece with a lobed margin [fig.5]. The labrum [fig.8] 

 is hairy as usual, the clypeus [fig.Se] with two stout spines on 

 its dorsal surface. On the gula arie two trifid hairs. The 

 thorax is rounded, and at the base of the larger j^ufts of hair 

 are spurlike processes with four or five teeth projecting ceph- 

 alad. The long, loosely feathered hair tufts of the thorax con- 

 sist of the usual anterior transverse row, and the two lateral 

 groups [fig.3]. The hairs of the abdomen are arranged in tufts 

 of about equal length, though there are fewer hairs in the pos- 

 terior ones; air tube brown, of moderate length, the row of 

 lateral epines on it each with from 15 to 20 spines; caudad 

 of which are a few long hairs. The lateral combs of the eightb
