(Mono, Culicid. I., p. 250, 1901.) 
Additional characters :— 
6. The mid last tarsal joint has a dense tuft of Black scales, 
and the ungues are unequal, the larger being thick and blunt, of 
peculiar, form as in remipes. 
Head with also silvery scales laterally and some peacock 
green ones, deep violet in some lights. Proboscis distinctly 
swollen at the apex. 
The base of the first sub-marginal cell a little the nearer of 
the fork-cells to the base of the wing; posterior and mid cross- 
veins apparently nearly in a str cht, Hee 
@?. The ? resembles the ¢. Head dark, with deep blue 
and violet scales; palpi, proboscis and antennae deep brown ; 
proboscis a little longer than in the ¢ ; basal joint of antennae 
silvery grey. Thorax black, with deep metallic blue scales, 
becoming almost green in front of the wings, those on the 
scutellum brilliant blue ; pleurae bright silvery. 
Abdomen deep blue, venter silvery white ; in some lights the 
dorsal and lateral areas are purple and coppery red. 
Legs as in the g, but the ungues all equal and simple and 
the last mid tarsus does not seem to be densely scaled. 
Wings with the fork-cells long, the first sub-marginal con- 
siderably longer than the second posterior, its base much. nearer 
the base of the wing, its stem a little less than one-third the 
length of the cell ; the posterior cross-vein about the same length 
as the mid and slightly nearer the apex of the wing. At the 
base of the wing, posteriorly situated, are some reddish golden 
bristles. Halteres tawny at the base, fuscous apically and on 
the stem. 
Length.—7 rm. 
Additional localities.—Haitaba, Lower Amazon, and Para. 
Time of capture.—April (Para). 
Observations._-Several 9’s have been sent by Professor 
Goeldi, as well as a single g@. The g resembles very closely 
the 9, but the strangely formed mid ungues easily separate the 
sexes. There is some slight variation in the white markings on 
the legs, but never on the paddles as far as I have observed.
