A New Species of Coniceromyia from Cuba 
159 
directed macrochsetse; palpi with moderately short bristles. 
Third antennal joint pyriform, pointed at tip, three-fourths as 
long as the eye; arista terminal, as long as the antenna. Meso- 
notum shining; with one pair of dorsocentral macrochsetse. Scu- 
tellum nearly half as long as wide, with four marginal bristles; 
one bristle above and several below the prothoracic spiracle. 
Mesopleura entirely bare. Front tibiae simple, not notched, nor 
emarginate, with a series of three large bristles, one at the basal 
fifth, another at the second fifth and the third just beyond the 
middle; all tarsal joints widened, the first with a triangular ex- 
tension along the inner edge and a slender, projecting process at 
the tip (Fig. 1, h) as in C. anacleti Borgm. Middle tibia with a 
pair of very large bristles near the basal fourth on the posterior 
surface and another, not quite so large externally before the tip. 
Hind tibia with one large bristle- just before the middle behind, 
one externally at apical fourth and three terminal spurs. Ab- 
domen large, dull above, with' none of the segments lengthened. 
Costa half as long as the wing, (Fig. 1 , a) its bristles very short 
and closely placed, very slender at base gradually thickened 
beyond and very broad at apex; first vein thickened just before 
tip; third vein stout, of even thickness; fourth vein unusually 
close to the costal margin, slightly curved at base; fifth, sixth 
and seventh veins nearly straight. 
Female. Length 1.3 mm. Similar to the male, except that 
the antennae are small, oval, with dorsal arista and the fore tarsi 
are simple, with the second to fifth joints slightly broadened. 
Types from the San Juan Mts. near San Bias, Province of 
Santa Clara, Cuba, February 1927. 
The female is very much smaller than the male, but this un- 
doubtedly represents only individual variation as there are no 
morphological differences aside from the secondary sexual cha- 
racters of the antennae and front tarsi. 
As indicated in the preceding key, this species is distin- 
guishable from the three known South American species by the 
presence of a series of three large bristles on the anterior tibia; 
from C. anacleti and C. epicantha by its dark color, and from C . 
fusca and C. epicantha by the appendage of the first tarsal joint 
of the front leg. This peculiar structure is present in C. anacleti.
