BITING MIDGES — WIRTH AND BLANTON 379 



Blanton, light trap. Paratypes, 1 male. 7 females, same data except 

 dates November and December 1952. 



Discussion: This species is very closely related to mojingaensis 

 Wirth and Blanton, but can readily be distinguished by the sub- 

 median mesonotal spots being bluish instead of bright yellowish, vein 

 M2 not extensively pale margined distallj^, the distal pale spot in 

 cell Ml nearly meeting the wing margin, the apex of the male aedeagus 

 stouter, and the tips of the parameres much slenderer.

Culicoides mojingaensis Wirth and Blanton, 1953, Journ. Parasit., vol. 39, p. 232 

 (male [sic], female; wing, mesonotum, palpus, spermathecae, male genitalia [sic]). 



Female: Length of wing 0.96 (0.89-1.02, n = 5) mm. 



Head. — Eyes contiguous, bare. Antenna with flagellar segments 

 in proportion of 16:10:11:12:13:14:14:15:22:23:25:27:43, antennal 

 ratio 1.32 (1.31-1.33, n = 2), distal sensory tufts present on segments 

 III, viii-x, rarely present on vii. Palpal segments in proportion of 

 9:16:24:9:9, third segment moderately swollen, 2.1 (1.8-2.3, n = 5) 

 times as long as broad, with a broad, shallow, sensory pit. Mandible 

 with 14 (n=4) teeth. 



Thorax. — Mesonotum with a conspicuous 4-colored pattern; a 

 median anterior marginal spot blackish ; a pair of elongate submedian 

 anterior spots yellowish; irregular lateral spots and prescutellar area 

 bluish gray pollinose; and a pair of angular, sublateral bands, broad- 

 est at the lateral suture, deep brown. Scutellum brownish in middle, 

 yellowish on the sides; postscutellum and pleuron dark brown. Legs 

 dark brown, all femora with subapical, tibiae with subbasal and hind 

 tibia with apical, narrow pale rings; hind tibial comb with four (n = 7) 

 spines, the one nearest the spur longest. 



Wing. — Pattern as figured ; second radial cell very dark ; r-m cross- 

 vein in a very large pale spot extending from costal margin to half 

 of distance across cell M2; cell R5 with two pale spots, a narrow, 

 U-shaped, poststigmatic area which isolates a small, round, dark spot 

 behind end of second radial cell, the distal pale spot in cell Rs large 

 and diamond-shaped, broadly meeting wing margin anterodistad and 

 the posterior corner joined with pale line bordering vein Mi; two 

 pale spots in cell Mi, each fusing with the pale line bordering vein Mi 

 which extends distad from the proximal pale spot in cell Mi, distal 

 pale spot in cell Mi located more than its own length from wing 

 margin; distal third of vein M2 pale-margined; cell M2 with two pale 

 spots in distal part, the distal one small and round and not quite 

 meeting wing margin; apex of vein M3+4 with a pale spot at wing 

 margin; cell M4 with a large round pale spot in middle of cell, barely
