170 MOSQUITOES OF NORTH AMERICA 



sparsely plumose, and black. Proboscis very long and slender, curved. Palpi 

 about two-thirds as long as proboscis, slender, unif oim, the last two and apex of 

 the long joints with a few short, coarse, outstanding setae. Coloration as in the 

 female. Abdomen laterally expanded at tip, the last segment and genitalia en- 

 tirely blue-black scaled below; separation of color on sides less sharply angular 

 than in the female. Claw formula, 0.0-0.0-0.0. 



Length : Body about 4.5 mm. ; wing 4.5 mm. 



Grenitalia (plate 7, fig. 48) : Side-pieces over twice as long as wide, strongly 

 tapered to a small tip ; three long setae on inner margin; basal lobes very large, 

 rounded, setose. Clasp-filament long, slender, with a short terminal claw. 

 Harpes prominent, with thickened margin and spinose tip. Harpagones and 

 unci forming basal cones, the harpagones prominently exserted. Basal append- 

 ages moderate, bearing very long setae. 



Larva, Stage IV (plate 94, fig. 306) . — Head well rounded, broader than long, 

 without prominent angles ; antennae moderately long, but very slender, weak and 

 flexuous near the base; maxiUae strongly projecting, fringed with evenly-spaced 

 hairs on inner side, a long terminal tooth projecting inward at right angles, 

 second tooth small and concealed from dorsal view; mandibles not visible from 

 above; all head-hairs single. Lateral abdominal hairs multiple on first two 

 segments, single on fourth to sixth. Lateral comb of eighth segment of four 

 teeth somewhat irregularly placed. Air-tube long, flared at base, slender out- 

 wardly and slightly curved forward, about five times as long as basal width, eight 

 times as long as diameter at basal fourth; evenly covered with small, stout 

 spines ; three fine hairs on dorsal aspect near the tip ; a row of densely placed 

 tufts along ventral line of three or four long, very fine hairs each, running from 

 base to tip, in all about thirty tufts. Anal segment longer than wide, with a 

 large dorsal plate; dorsal tuft of a group of three and another of five long hairs 

 on each side; lateral hair long, single, arising from angle of plate; subventral 

 tufts multiple, long, detached. Anal gills about five times as long as the seg- 

 ment, large and stout, gradually tapering to their tips, equal in length. 



The larvae are predaceous, feeding upon the larvae of species of Wyeomyia 

 living in the fluid in the flower-sheaths of plants of the genus Heliconia; they 

 occur singly. The adults are rare ; we have no information about their habits.

One of the type specimens of Lesticocampa rapax (Patulue, Guatemala) we 

 find belongs to this species (L. culicivora) .
