166 MOSQUITOES OF NORTH AMERICA 



the coloration of the scutellum, which is brown, concolcrous with the mesonotnin 

 in lunata, but bright metallic green, contrasting with the brown mesonotum in 

 rapax. We therefore retain this name for the Triaidad form, which doubtless 

 represents a distinct species. We possess but a single specimen, a male. 



Lesticocampa rapax was described from 4 specimens. Of these we leave the 

 male from Trinidad to represent the species, referring the 2 females from Brazil 

 to Lesticocampa lunata Theobald, and the specimen from Guatemala to Lesti- 

 cocampa culicivora Dyar & Knab.

 setae; vestiture brownish black. Palpi short, one-sixth as long as proboscis, 

 bronzy black, with a few outstanding setae. Antennae slender, basal joint about 

 four times as long as wide, terminal ones increasingly somewhat longer, rugose, 

 coarsely pilose, especially on the last two joints, black; tori subspherical with a 

 cup-shaped apical excavation, luteous brown, darker within ; hair of the whorls 

 sparse, moderate, black. Clypeus elongate, rounded, blackish, nude, with a 

 slight pruinosity. Eyes black, contiguous at the vertex. Occiput smoothly 

 clothed with flat appressed scales, blackish, a large vertical patch with a metallic 

 reflection, silvery in some lights; a row of erect, forked black scales along pos-

Abdomen subcylindrical, blunt at tip, with a terminal tuft of bristles ; dorsal 

 vestiture black with a brown and bluish submetallic reflection; venter yellowish 

 silvery, colors separated on sides in a straight line. 



Wings moderate, hyaline ; petiole of second marginal cell two-thirds as long 

 as its cell, that of second posterior cell nearly as long as its cell ; basal cross-vein 

 distant less than its own length from anterior cross- vein; outstanding scales 

 of the veins rather narrowly elliptical, denser and broader on forks of second 

 vein and at tip of third vein, brown with a blue reflection. Halteres with brown 

 stems and black knobs. 



Legs long and slender, black, with a bronzy and blue reflection, slightly paler

Male. — Antennae sparsely plumose, with the last two joints long and slender, 

 rugose, black, with long pile, the other joints shorter, about five times as long as 

 wide, with a large whorl at base and a secondary hair-whorl at middle, brown,
