and lower frons silvery white, between the two colors a velvet black 
spot. The wings have a dark brown crossband. 
Type localities—Oaxaca, Mexico; Brazil. 
Type.—In the Hofmuseum, Vienna. 
EPOMYIA, new genus. 
Nearly related to Psilocephala and Furcifera, four of the species 
having been taken from the former genus. No specimens of Furcifera 
were available for comparison, but from Kréber’s description it is 
clear that the genus is close to Hpomyia; both genera have enlarged 
metatarsi and a velvet black spot in the center of the frons and the 
antennae are evidently allied in structure. All of the known species 
of Epomyia have rather long, slender antennae, the third joint longer 
than the first and of a peculiar shape, the tip broad and hollowed out 
on the outside, the small style fitting in the excision. (See figs. 30, 31, 
32, 36, and 37.) The bristles on the first and second joints are very 
short and hairlike. There isa more or less elongated velvet black spot 
on each shoulder inside the humeral callosity. The scutellar bristles 
are very short and in some species variable in number. The wings 
are banded and are proportionately small, especially in the females, 
which have rather long slender abdomens. The venation is like that 
of Psilocephala, cell M—3, however, being closed in all the species and 
petiolate like the cell first A (anal cell). 
Genotype.—Psilocephala pictipennis Wiedemann.
