Diptera of Middle America. 
335 
Legs brown, coxae and parts of the femora darker, bases of the 
tibiae somewhat paler. Abdomen generally black, second seg¬ 
ment narrow and elongate, on basal half with two transparent 
spots separated by a black interval, apex of the same segment 
with a narrow pale band, apex of the third segment with a narrow 
band of golden yellow pile, apex of the fourth segment and all 
of the fifth brownish. A male type taken at Los Amates, Guate¬ 
mala, in February, 1905. 
This species is related to Willistons’ bellula but differs from it 
in having entirely hyaline wings, and the coloration of the legs 
and abdomen is quite different. Also the elongation of the 
stump of a vein from the third longitudinal almost dividing the 
first posterior cell appears to be an important characteristic of 
claripennis. 
Baccha Fabricius. 
Baccha callida n. sp. Length about 10 mm. Front with a 
slight prominence for the insertion of the anenme, front, face and 
antennae yellow, a small geminate black spot on the middle of the 
front near the antennae. Thorax largely yellow with four black 
stripes separated by yellow on the dorsum, and an irregular greenish 
brown marking passes beneath the scutellum to the bases of the 
middle legs; wings narrowly at base and along the anterior border 
pale yellowish, otherwise clear hyaline; legs all yellow with the 
exception of the hind pair, each of which have a pale brown band 
around the apical third of the femur and a wider band of the same 
color on the basal half of the tibia. Abdomen black, brown and 
yellow, first segment yellow with a black marking beneath the 
scutellum and a clear brown band on the posterior margin, second 
segment brown on anterior half, this followed by an area of vel- 
lowish somewhat intermixed with brown and this by a black band 
occupying more than the apical fourth of the segment, third 
segment with a middorsal stripe slightly abbreviated before, an 
apical band and an oblique marking on each side connected with 
apical band black, fourth segment like the third, fifth segment 
with three black stripes, all the segments behind the second are 
yellowish where they are not black. 
The male type collected at Puerto Barrios, Guatemala, March 
5, 1905. 
This species is somewhat suggestive of lineata but is colored 
quite differently. 
Baccha capitata Loew. A female example of this fine species 
was taken at Holguin, Cuba, by H. S. Parish. The species has 
been reported from Cuba and Porto Rico by previous writers. 
Loew’s type is a male. From reading the original description and 
comparing my specimen with it I find the two sexes are very 
similar in coloration.
