the lobes scarcely darker than the median area; scutehum pallid;

erate in length, extending to about one-fourth the length of the 
sector; Rs elongate, somewhat arcuated at its origin; cross-vein 
r at the tip of Ri; basal deflection of 7?4+5 more than two times the 
length of the r-m cross-vein; cell 1st M2 elongated, the cell being 
longer than vein Cui beyond it, though shorter than vein M',+2 
beyond it; basal deflection of Cm, just before the fork of M.

Habitat. — Santo Domingo. 
Holotype, 9 , San Francisco Mountains, Santo Domingo, Septem- 
ber, 1905 (Aug. Busck). 
Type in the collection of the United States National Museum. 
This species is closely related to G. dnereinota in its short rostrum, 
conspicuous black thoracic stripe, uniform femora, etc. ; it is a smaller 
fly, with the head black and silvery, without the clear gray coloration 
of the praescutum, the stigma indistinct and the flagellar segments 
much shorter and more globular than in the corresponding sex of 
dnereinota. 
Geranomyia tibialis Loew. (Plate XXV. fig. 5.) 
Aporom tibialifi Loew; Linntea Entomologica, vol. 5, p. 397 (1851). 
A wide-ranging species throughout the Antilles and southward 
over a large portion of South and Central America. The following 
unrecorded stations are before me, representing the Loew collections 
in the Museum of Comparative Zoology, the American Museum and 
the United States National Museum: 
Cuba, part of the Loew collection in the M. C. Z., bearing the label 
"rufescens" in Osten Sacken's writing, but certainly not that species 
because of the black and enlarged apices of the anterior tibiae; a cf, 
Baracoa, September, 1901 (Aug. Busck). 
Sa7ito Domingo, several cf 9, Sanchez, June 7-12, 1915; cf, San 
Francisco Mountains, September, 1905 (Aug. Busck). 
Porto Rico, 9 , Aguadilla, January, 1899. 
Montserrat, a 9 , Plymouth (F. Driver). 
Ca7ial Zone, a 9 (A. H. Jennings). 
The species may be looked for in the Miami (Dade County) 
section of Florida.
