FLIES OF THE TRIBE LESKIINI—JAMES 113 
scutellum, and uppermost parts of pleura deep yellow, almost golden, 
remaining pollen of pleura whitish with a slight yellow tinge; inner 
vitta of mesonotum as broad as diameter of a trichopore of a dorso- 
central bristle. Hairs of mesonotum (except notopleura), scutellum, 
and upper parts of humeri coarse, black; those of thorax otherwise fine, 
yellowish. Legs yellow, tarsi becoming brownish apically; coxae 
whitish pollinose, legs otherwise without pollen; coxae and posterior 
and posteroventral surfaces of femora chiefly whitish pilose, legs other- 
wise with black stiff hairs. Wings hyaline; R: with setulae uniformly 
spaced or but slightly more closely set in the stigmatal region. Squamae 
and halteres yellow. 
Abdomen yellow; second and third segments, sometimes also first, 
each with a median apical black spot dorsally; third, fourth, and some- 
times second, with a small apical spot on each side; the lateral spots, in 
particular, however, show a tendency to disappear. Abdomen dorsally 
shining, ventrally with inconspicuous whitish pollen visible in an 
oblique light. Hairs of first segment ventrally mostly pale; those of 
rest of abdomen black. First segment with weak though distinct 
median marginals. 
Types.—Holotype, male, Chain Bridge, Va., August 3, 1923 (J. M. 
Aldrich), U.S.N.M. No. 57292. Allotype, female, Plummers Island, 
Md., September 29, 1912 (P. R. Meyers). Paratypes: one female, 
Chain Bridge, Va., June 25, 1923 (J. M. Aldrich) ; one female, Plum- 
mers Island, Md., August 18, 1912 (J. R. Malloch); one female, 
Lafayette, Ind., September 9, 1916 (J. M. Aldrich) ; one female, At- 
lanta, Ga., June 30, 1930 (P. W. Fattig) ; one male, one female, Monti- 
cello, Fla., July 27, 1914 (A. I. Fabis), Quaintance No. 10573, “bred 
from 7’. subcanalis Walk.,” August 24 and 21, 1914 [all U.S.N.M.]; 
one female, Manhattan, Kans., October 1924; three females, Babylon, 
Long Island, N. Y., June 28, 1935, and July 2, 1936 (Blanton and 
Borders), and June 25, 1985 (F. S. Blanton) [H. J. Reinhard 
Collection]. 
This species has been reared from J'etralopha subcanalis (Walker). 
The best disposition of Deaia analis Say is to place it, as Smith ® 
suggested, among the unidentifiable species. Coquillett *° considered 
it a synonym of, and therefore holding priority over, his Myobia depile 
(=Leskiopalpus depilis (Coquillett)). Aldrich, however, disagreed 
with Coquillett’s interpretation of Dexia analis, apparently on the 
strength of Say’s statement that “the proboscis and palpi are much 
elongated.” 
I believe, however, that Coquillett was more probably right than 
Aldrich. Say’s description, in part, reads “proboscis black, yel- 
low at tip; thorax black, with a somewhat golden reflection; a dull
