420 MOSQUITOES OF NORTH AMERICA 



Wings moderate ; hyaline ; petiole of second marginal cell about one-third as 

 long as its cell, that of second posterior cell shorter than its ceU ; basal cross-vein 

 abont twice its own length from anterior cross-vein ; scales of veins brown, with 

 a bluish reflection on costa, outstanding ones linear, somewhat denser on forks 

 of second vein and apical portion of third vein. Halteres whitish, with brownish 

 knobs. 



Legs moderately slender; vestiture of black scales with a bronzy and blue 

 luster, femora broadly white beneath to tips ; knees and tips of tibise whitish ; 

 tibiae and tarsi with a brassy luster on imder side, the bases of the tarsal Joints 

 slightly paler. Claw formula, 0.0-0.0-0.0. 



Length : Body about 3 mm. ; wing 3 mm. 



Male. — Proboscis straight, gradually enlarged towards apex, black scaled 

 above, a broad pale diffuse ring near middle; imder surface psder scaled, the 

 ring more distinctly white. Palpi exceeding tiie proboscis by nearly the length 

 of the last joint, slender, the apical portion somewhat enlarged; vestiture black, 

 without rings ; long, abundant black hairs on end of long joint and on last two 

 joints. Antennae plumose; last two joints long and slender, rugose, pilose, 

 black, the others short, whitish, with thick black rings at insertions of hair- 

 whorls; hairs long, dense, brown; tori entirely brown. Coloration similar to 

 the female. Abdomen elongate, depressed, slightly expanded towards apex; 

 dorsal white bands slightly broader, laterally expanded on seventh segment; 

 lateral ciliation long, fine, abundant, yellowish. Wings narrower than in the 

 female, the stems of the fork-cells longer, vestiture less abundant, outstanding 

 scales on apical portion of wing somewhat broader. Claw formula, 1.1-1.1-0.0. 



Length : Body about 3.5 mm. ; wing 2.7 mm. 



Genitalia (plate 14, fig. 103) : Side-pieces over twice as long as wide, rather 

 slender, tips conieally rounded; inner process stout, quadrate, situated weU 

 above middle bearing four rods, a leaf-like appendage and two setae ; clasp-fila- 

 ment tapering outwardly, with a small terminal claw. Harpes with inner Umb 

 stout tufted at tip, outer long, curved; harpagones divided into a number of 

 intricate plates, forming a series of projecting points and teeth ; basal append- 

 ages rounded, setose. 



Larva, Stage TV (plate 98, fig. 323). — ^Head rounded, widest through eyes, 

 wider than long; antennae long, stout, a large tuft at outer third, tiie part 

 beyond more slender, shaft spinose; both pairs of dorsal head-hairs in threes; 

 ante-antennal tufts multiple. Body glabrous; lateral hairs of abdomen in 

 sixes on first segment, fours on second, twos on third to fifth, single on sixth. 

 Lateral comb of eighth segment of many spines in a large triangular patch. 

 Air-tube about three times as long as wide, outwardly tapering; pecten reach- 

 ing to three-fourths of length of tube, the teeth becoming long outwardly; three 

 hair-tufts within pecten of two hairs each, a smaller lateral tuft before the last; 

 terminal hooks minute. Anal segment about as long as wide, spicular pos- 

 teriorly; dorsal tuft of three hairs on each side; lateral hair small, single; 

 ventral brush well developed, confined by the chitinous ring. Anal gUls twice 

 as long as the segment, equal, their tips pointed. 



The larvae live in ground-pools and artificial receptacles. Mr. Busck got them 

 in a stagnant pool and in a rain-barrel; Mr. Jennings got them in a tree-hole.

Tabernilla, Canal Zone, April 26, 1907 (A. Busck) ; Ancon, Canal Zone, 

 November 21, December 5 and August 9, 1908 (A. H. Jennings) ; Taboga Island 

 (A. H. Jennings). 



Culex reflector is allied to the more northerly distributed CuUx interrogator, 

 with which we at first identified it, and which identification was published by 

 Mr. Busck. We find, however, certain differences which we consider to be of a 

 specific character, as shown in the tables.
