The male terminalia of these specimens, however, were identical to 
A. specus (Aldrich), whereas the terminalia of European specimens 
of A. praecox Loew differ noticeably. 
Aecothea fidelis Curran 
Oecothea fidelis Curran, in Curran and Alexander, 1926, p. 290.—Czerny, 1928, 
p. 54. 
I have examined a female paratype of this species in the American 
Museum of Natural History. It appears very similar to the females 
of the preceding two species. The specimen was in poor condition 
and lacked the antennae (except bases), bristles of the head and 
thorax, and one wing. The remaining wing had a brownish tinge 
and the anterior crossvein was clouded. This clouded crossvein is the 
character used by Curran to separate this species from others in 
the genus.

Viatica Garrett, 1924, p. 32—Czerny, 1927b, p. 40, New synonymy. 
The presence of rows of bristles on the anterior surface of the mid- 
dle femur will aid in distinguishing Hccoptomera from related genera. 
When Garrett described the genus Viatica, the only species of 
Eeccoptomera known from North America was £. simplex Coquillett. 
Garrett’s Viatica differed from the latter in that the eye was much 
larger, two distinct fronto-orbital bristles were present, and the male 
hypandrium showed short, stout spines not found in E. simpler 
Coquillett. As more specimens have accumulated and new species been 
discovered, there appears to be an intergradation of characters which 
eliminates the distinction between Viatica and Eccoptomera. For
