CULEX RESTUANS 333 



white spots indistinct; bristles at ends of segments coarser, brown; no lateral 

 ciliation. Claw formula, 1.1-1.1-0.0. 



Length : Body about 3.5 mm. ; wing 3 mm. 



Genitalia (plate 9, fig. 62) : Side-pieces about three times as long as wide, 

 conically tapered; lateral process beyond outer third, divided, both portions 

 quadrate, the outer bearing three rods, the inner two rods ; clasp-filament rather 

 stout, uniform, ynth a small, stout, terminal claw. Harpes divided, inner limb 

 slender, long, with crown of five or six spines, outer limb reduced to a small 

 angle. Harpagones lamelliform, small. Basal lobes rounded, rather remote, 

 setose. 



Larva, Stage IV (plate 110, fig. 369). Head rounded, widest through eyes, 

 somewhat narrowed in front; antennae long and stout, tuft almost at outer 

 fourth, part beyond more slender ; upper pair of head-hairs long, in threes ; lower 

 very long and single. Body with skin glabrous ; lateral abdominal hairs in twos 

 or threes on third to fifth segments, single on sixth ; lateral comb of eighth seg- 

 ment of many spines in a large triangular patch. Air-tube long and slender, a 

 little flaring at base, then straight, about eleven times as long as wide; pecten of 

 short teeth on basal fifth, followed by five short single hairs along posterior 

 aspect. Anal segment twice as long as wide, ringed by the plate; dorsal tuft 

 of two long hairs on each side ; lateral hairs a small multiple tuft ; ventral brush 

 well developed, confined by the chitinous ring. Anal gills shorter than the seg- 

 ment, slender, equal, their tips rounded. 



The larvae live in tree-holes. Mr. Knab found them in a small hole in a tree 

 in a ravine. Later he found them in a large hole in a mango tree, about 3 feet 

 from the ground; the tree was on a hill-side in a coffee orchard. The water in 

 the hole was very dark, containing much rubbish and dead leaves, and larv^ of 

 Aedcs osivaldi, another tree-hole inhabiting species, were associated. No adults 

 were obtained from the larvae upon which Culex restrictor was founded. While 

 the larvas from Cordoba do not agree exactly with those obtained at Almoloya, 

 our material from the latter place is so unsatisfactory that we think it ad^^sable 

 to consider them conspecific, the agreement in habits making this probable.
