Brookline, Chester, Bashbish Falls, Massachusetts (C. W. Johnson); 
Apponaug, Rhode Island (C. W. Johnson); Plattsburg (H. G. Dyar), 
Niagara Falls (C. W. Johnson), Staten’ Island, (F. Schrader), New York; 
Westville, Delaware Water Gap, Dover, Newark, Riverton, New Jersey 
(C. W. Johnson); type locality of humeralis (Loew coll.), Philadelphia 
(C. W. Johnson), North Mountain (C. W. Johnson), Pennsylvania; Plum- 
mer’s Island, Maryland (J. R. Malloch); District of Columbia (type of 
leucostoma); Scotts Run (H. 8S. Barber), Great Falls (Nathan Banks), 
Dead Run (R. C. Shannon), Virginia; La Fayette, Indiana (J. M. Aldrich) ; 
Chiric Mountains, Arizona (H. G. Hubbard). 
The species of this group have apparently not been bred. They are to 
be found in woods, and are stated to be attracted by perspiration and to 
hover near the eyes of people. 
Zaprionus Coquillett. 1902. Proc. U. S. Nat. Mus., 24, 31. 
Arista plumose; three orbitals, lower (proclinate) placed well below the other two 
(reclinate); postverticals large, convergent; ocellars present; vibrisse present; eyes 
densely pubescent; face and carina prominent; one presutural; two notopleurals; two 
supra-alars; two postalars; two dorsocentrals; prescutellars very small or absent; two 
pairs of scutellars; disk of scutellum bare; two sternopleurals; preapicals on second tibie; 
costa twice broken: auxiliary vein rudimentary; discal and second basal cells confluent; 
anal cell and anal vein present. The tubercles on the under side of the front femora stated 
by Coquillett to be present in the male of the type species occur in the female of that species 
also, but are absent in the other two species that I have seen. 
The type species is Z. vittiger Coquillett. It is recorded in the Ethiopian 
region from Rhodesia (Coquillett); Kamerun (Kahl); Senegal, Eritrea 
(Bezzi); Seychelles (Lamb). I have seen specimens from Liberia (R. P. 
Currie). Drosophila orbitalis Sturtevant, from Panama, belongs in this 
genus. I have seen, in the United States National Museum, specimens of 
an apparently undescribed species collected in India (Compere) and in 
Java (Bryant and Palmer). 
The type specimens of Z. vitiiger, collected by C. P. Lounsbury, are 
labeled “prickly pear.”’ This is the only hint as to the habits of the genus 
that I have found. 
Pseudophortica Sturtevant. 1918. Journ. N. Y. Ent. Soc., 26, 37. 
Arista plumose; three large orbitals, upper two reclinate, lower proclinate and situated 
above middle of front; postverticals small, widely separated, convergent; front covered 
with black hairs except at vertex; face with well-developed carina; one large vibrissa; 
eyes nearly bare; two dorsocentrals; one prescutellar; acrostichal hairs in more than ten 
irregular rows; one humeral; one presutural; two notopleurals; two supra-alars; two 
postalars; two pairs of scutellars, posterior ones crossed; one small propleural; two sterno- 
pleurals; mesopleure bare; several apical bristles on each tibia, those on the second pair 
larger; a few short, stout apical bristles on each of the four basal tarsal joints of the second 
and third pairs of legs; costa twice broken, reaches apex of fourth vein, but is very weak 
beyond the third; auxiliary vein rudimentary, but a shadow continues to the distal costal 
break; discal and second basal cells united; third and fourth veins slightly divergent at 
tips; wing tip rounded. 
The type and only recorded species is Pseudophortica obesa Loew (1872, 
Berlin ent. Zeit., 16, as Drosophila) = Phortica hirtifrons Johnson (1913, 
Bull. Amer. Mus. Nat. Hist., 32, 88). 
Specimens examined: Ocean View, Virginia (A. N. Caudell); Coal Creek, 
Tennessee (W. S. Adkins); Southern Georgia (Morrison: this specimen is 
headless); Lakeland (C. W. Metz), Crescent City (M. C. Van Duzee, type 
of hirtifrons), Florida; Kushla, Alabama (on persimmons); Texas (type 
material of obesa).
