no. 3626 CULICOIDES — WIRTH AND LEE 21 



flagellar segments in proportion of 17-14-16-17-17-17-17-17-19-19- 

 21-22-31, antennal ratio 0.85; distal sensory tufts present on segments 

 in, xi-xiv, 4 sensoria on xiv. Palpal segments (fig. Qg) with lengths 

 in proportion of 7-19-22-8-6; third segment short and swollen, 2.0 

 times as long as greatest breadth, with a small, deep sensory pit. 

 Proboscis short, p/h ratio only 0.75; mandible with 11 teeth. 



Thorax: Brown; scutum with moderately distinct pattern, which in 

 slide-mounted specimen appears to include many small brown punc- 

 tures around the seta bases; scutellum yellowish on slides. Legs pale 

 brown; blackish knee spots present on all legs; fore- and midfemora 

 with narrow subapical pale rings, all tibiae with narrow sub-basal 

 pale rings and hind tibia with apex pale; hind tibial comb with 4 

 spines, the one nearest the spur longest. 



Wing (pi. 1: fig. 10): Pattern as figured; second radial cell dark to 

 apex; with moderately distinct pale spots as follows: a moderately 

 large pale area just distad of basal arculus; a somewhat transverse 

 pale spot centered on r-m crossvein and extending from costa to 

 media; a single oblique poststigmatic pale spot extending posteriorly 

 only three-quarters the breadth of cell R5; a transverse subapical 

 pale spot in cell R5 reaching neither anterior nor posterior cell margins; 

 2 small pale spots in cell Ml, the distal one much distant from wing 

 tip; cell M2 with a distinct double pale area lying between medial 

 and mediocubital forks, a distinct, small, round pale spot near wing 

 margin in tip of cell, but no spot between these pale spots; cell M4 

 with round pale spot near apex; anal cell with single transverse pale 

 spot extending from near mediocubital fork to posterior wing margin. 

 Macrotrichia very sparse on distal half of wing, none extending 

 proximad of level of end of costa; costa extending to 0.61 of distance 

 to wing tip; radial cells with distinct lumens, the second moderately 

 broad. Halter not visible in slide-mounted specimen examined. 



Abdomen: Dark brown. Spermathecae (fig. Qh) 2, subequal, moder- 

 ately large, ovoid with long, slender, sclerotized necks; rudimentary 

 spermatheca and elongate sclerotized ring present. 



Type. — Holotype female: Finca Carpenteria, El Tambo, Cauca, 

 Colombia, 2500 m, July 9, 1964, V. H. Lee, light trap, USNM type 

 no. 69404. 



Remarks. — A male specimen (from the Paramo de Purace, 28.4 

 km east of PuracS, Cauca, Feb. 18, 1965, V. H. Lee, at light) is thought 

 to be the male of C. tamboensis, because of the following similarities : 

 Eyes hairy; wing 1.20 mm long, pattern (pi. 1 : fig. 9) as figured, very 

 similar to the female but with the poststigmatic pale spot broader 

 and not as oblique, the pale spot lying immediately in front of medio- 

 cubital fork not distinct, the distal pale spot in anal cell extending 

 quite broadly to wing margin. The scutum is darker than in the female
