1924] New and Unrecorded A?nerican Species of Phoridce 161 
first section barely longer than the other two together; third 
fully one third as long as the second and as long as the second 
vein; fourth vein feebly curved on basal half, straight beyond; 
fifth weakly sinuous on basal half, straight beyond, without a 
sharp bend before the middle, sixth and seventh nearly straight, 
the latter faint. 
Type from Grenada, B. W. I. (Brues), 1910. 
This species is at once distinguished from A. magnipalpis 
Aldrich from the same island, by the much more slender legs, 
opaque velvety black abdomen, normally curved fifth vein and 
by the complete absence of any cilia on the middle tibiae. The 
palpi although similarly enlarged in the male, are more slender 
than in magnipalpis. 
A. opaciventris does not closely resemble any European or 
North American species. Any of these which might be other 
wise confused with it have the fore tarsi enlarged. 
Aphiochaeta giraudii Egger. 
This European species has already been reported from 
North America by Mrs. Slosson on the basis of specimens de- 
termined by Coquillett. It appears that this identification was 
incorrect, however, and Malloch removed the species from the 
North American list in 1912.^ 
I have a male, however, collected by Mr. C. W. Johnson at 
Fort Kent, Maine which is undoubtedly this species. The only 
difference that I can detect is the shorter basal section of the 
costa which equals but is no longer than the second and third 
together. The specimen is rather large and has the second row 
of setulse on the hind tibia well developed.
