182 NEW NORTH AMERICAN ANTHOMYIIDAE (dIPTERa) 



two or three posterior bristles; hind femur with a series of bristles on antero- 

 ventral surface and another of shorter bristles on basal half of postero-ventral ; 

 hind tibia with one antero-vcntral, three antero-dorsal and two postero- 

 dorsal bristles. Costal thorn very small; wing slightly pointed; third and 

 fourth veins slightly convergent apically, the former ending almost in wing- 

 tip; outer cross-vein curved. Lower calyptra protruded. 



Female.— Biffers from the male in being opaque, densely gray pruinescent, 

 and in having the interfrontalia, parafacuals and the cheeks largely rufous, 

 the thorax very indistinctly brown vittate, the abdomen with the dorso- 

 central vitta very faint, and all tibiae rufous. 



Interfrontalia without cruciate bristles; orbits well defined, each al^out 

 one-half as wide as interfrontalia. Fore tibia with an antero-dorsal bristle 

 beyond middle; antero-dorsal mid tibial bristle very much stronger than in 

 male; hind femur with fewer bristles on antero-ventral and postero-ventral 

 surfaces. Costal thorn larger than in male. 



Length, 5 mm. 



Type.— c^; Swarthmore, Pennsylvania, May 5, 1907, [A. N. 

 S. P., Type no. 6231]. Allotype — 9 ; topotypical. Paratypes.— 

 One male, topotypical; two males and one female, Augerville 

 Grove, Urbana, Illinois, April 18, 1919; one male, Savoy, Illinois, 

 May 4, 1916, on apple blossoms, (J. R. Malloch) ; one male, 

 Falls Church, Virginia, April 27, 1915, (C. T. Greene). 



This species superficially resem})les Hyletuyia trmttata Stein, 

 but the abdomen has a broader dorsal vitta, and is not con- 

 spicuously narrowed in the male at apex, nor is the fourth tergitc 

 conspicuously elongated in the female, and the bristling of Ihe 

 hind tibia is dift'erent.

Male and f('iN<il('.—B\ack, slightly shining. Orbits, fac(\ and chocks witli 

 whiti.sh pruinescence, anterior margin of interfrf)ntalia in l)oth sexes usually 

 reddish; .second antennal joint rufous. Wings slightly infuscated; iiuier 

 cross-vein clouded. Calyptrae white. Halteres yellowish, the kn()l)s brown- 

 ish yellow. 



Male. — Eyes separated by a little more than the width across post(>rior 

 o(!elli; orbits with hair-like bristles to beyond middle; second antennal joint 

 without pruinescence on inner surface, the basal half granulose, ai)ical hall 

 with some rather large irregular punctures, the apical margin dislinclly 

 angulated; third joint rounded at apex, minutely pilose; 'arista microscopically 

 pubescent; vibrissa long, a scries of six or seven long bristles ventrad of it. 

 and a grouj) of about a dozen short stout bristles at its base; i)arafacial widci'
