 Vermont (C. AV. Johnson) ; Newton, North Adams, Riverside, Auburndale, 

 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); tj'-pe 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. S. 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; vibrissse 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 tibia? ; 

 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 orhitalis 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. vittiger, 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. See, 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; mesopleursB 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 sUghtly 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).
