Distribution.—Cayman Islands, Costa Rica, Cuba, El Salvador, Guatemala, Jamaica, Mexico, Panama (fig. 4). Type.—Holotype, male, Barro Colorado Island, C.Z., from flowers of Heliconia mariae (USNM 54360). West Indian Records.CAYMAN ISLANDS: Grand Cayman, June 1970, J. E. Davies, 1 female. CUBA: Guantanamo Bay, 21 February 1962, E. R. Turner, light trap, 1 female.
JAMAICA: Askenish, near Dolphin Head, Hanover Parish, 20 June 1970, E. G. Farnworth, light trap, 1 female; Hardwar Gap, Inst. Jamaica cabin, Portland Parish, 20 February 1969, W. W. Wirth, light trap, 1 male, 7 females; 2 mi. w. Manchioneal, Green Hills, Portland Parish, 24 November 1968, R. E. Woodruff, light trap, 10 females. Discussion.—This species has a wing pattern similar to that of its relative, C. jamaicensis, but it has only one pale spot in the distal portion of the anal cell and the pale spot typically straddling the base of vein M1 has present only the portion lying on the anterior side of the vein; the retort-shaped spermathecae are quite distinctive. Larval Habitat. — Wirth and Blanton (1959) reported a rearing by J. Zetek in Panama from flowers of Heliconia mariae Hooker-F., the beefsteak Heliconia. Biting Habits.-Wirth (1955) reported this species feeding on horses and mules in Guatemala.

Culicoides undecimpunctatus Kieffer, 1917, p. 307 (female; Argentina).
Female.—Wing length 0.78 mm. Head: Eyes broadly separated, bare. Antenna (fig. 25, a) with lengths of flagellar segments in proportion of 15–11–12–14–14–14–14– 15–15–16–16–16–25; AR 0.77; sensory pattern 3,8–10. Palpal segments (fig. 25, f) with lengths in proportion of 8–17–20–7–10; PR 2.1; third segment slightly swollen with small, deep sensory pit.

except for the presence of the additional pale spots near the wing margin in the apices of cells R5 and M1, the pale spot present anterior to the mediocubital fork, and small differences in the proportions of the third palpal segment and the shape of the sensory pit. The two species share the tree hole habitat and much of the same geographic range. Larval Habitat.—Snow et al. (1957) and Smith (1965) found this species breeding in tree hole debris in Florida and Tennessee, Breeland (1960) reared it from tree hole debris in Panama, and Williams (1964) reared it from rotting cacao pods and a rotting calabash in Trinidad. Biting Habits.-This species was reported biting man in Panama (Woke, 1954; Wirth and Blanton, 1959), Guatemala (Wirth, 1955), Brazil (Lutz, 1913; Forattini, 1957), and Argentina (Romafia and Wygodzinsky, 1950). Snow et al. (1957, 1958) and Hair and Turner (1968) reported it as a troublesome, biting pest of man in the Southeastern United States. It is a forest species with daytime biting habits.
