30 Psyche [March-June 
remainder of that segment shining black. The pile upon the 
abdomen seems to be practically absent on the third and fourth 
segments, though whether this is due to denudation I cannot 
ascertain. The sparse lateral pile of the second segment is pale. 
Legs: almost wholly pale brownish-yellow; the narrow apices of 
the hind tibiae and the hind femora, a more obscure subbasal 
hind tibial band and the last two or three tarsal joints of all of 
the legs dark brown. Wings: very lightly tinged with brown; 
whole stigmal cell brown and the apical margin of the wing to 
just past the end of the third vein marginate with brown giving 
the impression of an elongate brown spot. 
Holotype: No. 23785, one male. Cuba, Wright, and one para- 
type. 
Baccha cubana n. sp. 
Related distantly to the lineata group; distinguished by the 
anchor-shaped abdominal pattern. 
Female. Length 7.5 mm.; wing 7 mm. Head: hemispherical, 
much wider than the thorax, the eyes large, bare, their posterior 
margins only slightly excavated. The occiput, except at the ex- 
treme ventral part, the vertex to just before the ocelli, obscurely 
shining black; vertical triangle quite narrow, lateral ocellus prac- 
tically touching eye margin, the ocelli set fairly well forward. 
Front, long widening to four times its width across ocelli with a 
conspicuous round black spot just above antennae; front except 
for this spot, and the face obscurely shining deep yellow, a little 
paler on the sides. Face with a low tubercle, almost straight and 
vertical front tubercle to antennae, but below the tubercle it re- 
treats rapidly the short distance from the oral margin ; there is a 
shallow concavity between epistoma and tubercle. Cheeks small 
and wholly yellow. Antennae short, third joint a little longer than 
wide, the first joint almost hidden; color of the antennae light 
orange, the third joint narrowly brownish above; arista blackish, 
basally thickened. Thorax: mesonotum broadly shining black; 
the shining yellow of the wide lateral margin of the thorax nar- 
rowly follows the suture inwardly on either side for a short dis- 
tance. Pleurae and scutellum wholly light brownish-yellow, the 
latter with a pair of black, short, apical bristles and just a few 
short black hairs on the disc. I can discern one or two tiny black 
hairs that may constitute a ventral fringe. Fringe may be absent. 
Squamae light yellow halteres yellowish with a brownish knob.
