380 DIPTERA. 
Rhopalomera, not belonging to any of the genera which Williston has separated from 
it; it has the legs densely haired, the hind tibie enlarged, and the wings without 
distinct markings. 
RHINOTORA. 
Rhinotora, Schiner, Reise der Novara, Dipt. p. 233 (1868). 
1. Rhinotora, sp. (Tab. X. figg. 4, head from in front; 4a, head in profile.) 
Hab. Costa Rica, Volcan de Irazu 6000 feet (Logers). 
A single male specimen. It does not fully agree with &. pluricellata, Schiner (l. c.), 
nor with ZR. diversa, Gig].-Tos (Mem. R. Accad. Sci. di Torino, ser. 2, xlv. sep. p. 43), but 
as it is somewhat badly preserved, I must abstain from describing it. 
STICTOMYIA. 
Stictomyia, Bigot, Bull. Soc. Ent. Fr. 1885, p. clxvi. 
1. Stictomyia longicornis. (Tab. X. figg.5; 5a, head from in front; 5}, head 
in profile; 5¢, wing seen against a dark ground.) 
Stictomyia longicornis, Bigot, loc. cit.’. 
._ Hab. Mexico !. 
Several years ago the late M. Bigot gave me one of his specimens (a female) of this 
species, and at that time I prepared some drawings of it, but neglected to make 
further notes. The insect is unfortunately in a bad state of preservation, and I 
therefore content myself with reproducing the figures, which will give a fair idea of 
the insect. I may note that the abdomen is not longer than the thorax, and much 
flattened. . 
STENOPTERINA. 
Stenopterina, Macquart, Suites 4 Buffon, ii. p. 453 (Senopterina) (1885).
