Female.—Wing length 0.91 mm.

Head: Eyes (fig. 17, g) narrowly separated, bare. Antenna (fig. 17, a) with lengths of flagellar segments in proportion of 16–12–12–12–12–12– 12–12–20–22–24–25–35; AR 1.28; sensory pattern 3,7–10. Palpal segments (fig. 17, c and d) with lengths in proportion of 11–24–28–10–13; PR 2.4; third segment slightly swollen, with small, shallow sensory pit. Proboscis moderately short, P/H ratio 0.74; mandible (fig. 17, h) with 15 teeth.

Thorax: Dark brown; mesonotum pollinose grayish, with prominent pattern of numerous scattered punctiform brown dots at seta bases; scutellum brown in middle, grayish pruinose on sides. Legs (fig. 17, i, k, l) brown; knee spots blackish; femora pale at bases, femora with subapical, tibiae with subbasal, and hind tibia with apical, narrow pale rings; tibial comb (fig. 17, j) with four spines, the one nearest the spur longest. Wing (figs. 17, e, 30, g): Pattern as figured; 2RC blackish; pale spot over r-m crossvein large; cell R5 with three small, round, poststigmatic pale spots in a triangle, the two next to 2RC more or less fused, and a large, oblique, double spot broadly meeting wing margin in distal part of cell; cell M1 with three pale spots, the distal one located at the wing margin; vein M1 pale margined from apex nearly to its base, veins M2 and M3+4 pale margined

[ocr errors]

on distal portions; cell M2 with pale streak in basal portion and a wider spot behind medial fork, two pale spots lying past level of mediocubital fork; cell M4 with large pale spot; anal cell with pale area at base and two pale spots in distal portion. Macrotrichia moderately numerous on distal half of wing and in anal cell; CR 0.58. Halter pale. Abdomen: Dark brown. Spermathecae (fig. 17, m) two plus rudimentary third and sclerotized ring; ovoid with long slender necks; subequal, each measuring 0.057 by 0.037 IIlms). Male Genitalia (fig. 17, n) Ninth sternum with broad, deep, caudomedian excavation, ventral membrane not spiculate; ninth tergum short and tapering with unusually long, slender, divergent, pointed, apicolateral processes. Basistyle with “foot-shaped” ventral root, posterior heel short, anterior toe long, dorsal root slender; dististyle slender, slightly curved, with bent pointed tip. Aedeagus with broad, rounded basal arch extending to about half of total length; basal arms slender; distal portion relatively short and stout, the apex of two types—in one the very slender, median, distally striate tip flanked by a prominent pair of lateral points of about the same length; in the other type the lateral points apparently lacking and the striated median tip broader. Parameres (fig. 17, o) separate; each with large basal knob, stem moderately stout and curved, bearing an extremely large ventral lobe; distal portion tapering

to fine point and bearing about five strong, lateral, fringing spines. Distribution.—Atlantic and Gulf coasts of the United States from Massachusetts to Florida and Texas; Caribbean and Atlantic coasts of Mexico, Central America, and West Indies to Brazil; Pacific coast from Mexico to Ecuador (fig. 5). Types.—Existence of types of C. furens unknown; described from north coast of Cuba, probably Havana. Holotype female of Ceratopogon maculithorac, Saint Vincent (British Museum (Nat. Hist.), London).

Discussion.—A full discussion of the taxonomy and distribution of this species was presented by Wirth and Blanton (1956c.; 1959). The extensive West Indian literature on the species is listed in the synonymy given on the preceding pages. Larval Habitat.—Myers' (1935) account of the larval habitat of C. furens in the Bahamas was the first detailed study in the West Indies, and its accuracy and definition, borne out by more recent investigations, warrant repetition:
