Frons slightly less than one-half the width of head, the sur- 

 face hairs short, though numerous, those on the lateral margins 

 not long, though setulose; triangle short and broad, not reaching 

 to middle of frons, and not half as broad as frons at vertex; an- 

 tenna with third joint as broad as cheek at middle, which is equal 

 to one-third the height of eye; cheeks with many soft hairs, which 

 are very short, the anterior hair distinguishable, but not vibrissa- 

 like; a distinct ridge traverses the cheek mid way between the eye 

 and the lower margin; eye slightly higher than long, pubescent. 

 Surface of mesonotum unpunctured, the space between the median 

 pair of vittae impressed ; surface hairs numerous, though short, and 

 regularly distributed; bristling normal; scutellum haired as meso- 

 notum, and with four marginal bristles, the basal pair very much 

 shorter than the apical pair, the latter not closely approximated, 

 cruciato; surface of scutellum convex, its outline rounded. Ab- 

 dornen ovate, as long as thorax. Legs normal. Wing with a distinct 

 break at apex of auxiliary vein, which vein is traceable; first costal 

 division subequal to second, third one half as long as latter; inner 

 cross-vein at a little before the end of first vein; the distance be- 

 tween its upper extremity and the inner cross-vein about three- 

 fourths the length of last section of fifth vein, and one-third as 

 long as last section of fourth; veins 3 and 4 subparallel. 



Length 2 mm. 



Type locality. — -Dubois, 111., April 24, 1914. Taken by sweep-

Paratype. — Same locality. Taken by sweeping. Related to 

 trigramma Loew, from which the difference in the thoracic mark-

Named in honour of Mr. A. A. Hinkley, the well-known 

 conchologist, on whose ground the species was taken, and to 

 whom we are indebted for much hospitality. 



Agromyza aristata, new species. 



Female. — Black; thorax very densely covered with pale gray 

 pollen, entirely opaque; abdomen less densely pollinose, slightly 

 shining. Head bright yellow, only the upper third of frons, includ-
