black, except the knees. (Alaska.) (Agj-omysa.) .parvicella CoquiUett.''- 



Dorsocentrals weak, thorax somewhat subshining, the sides broadly yellow; 



head yellow except the occiput; anterior tibiae and tarsi yellowish. 



(Id.*) plagiata sp. nov. 



3. Posterior crossvein in front of the anterior crossvein ; ovipositor depressed ; 



opaque black species with fuscous head, pale knees, notopleural stripe 



and incisures of abdomen. (Eur., Id.,* Wash.) anomala Strobl. 



Posterior crossvein opposite the anterior crossvein ; ovipositor compressed ; 

 mostly cinereous black, the head yellowish. (Eur.;* N. H., 111., Mo., 

 Col.,* Alaska.) lateralis Fallen. 



Napomyza plagiata new species. 



Female. — Length 2.5 mm. Robust, opaque blackish, the front, face, cheeks, 

 lower occipital orbits, proboscis, broad sides of the mesonotum, parts of the 

 pleurae, narrow apical margins of the first, second and fifth abdominal seg- 

 ments, root of wings, calypteres, knees, anterior tibiae and the tarsi yellowish ; 

 knob of halteres whitish. Front broad, a little dusky towards the antennae, 

 four fronto-orbital bristles; antennas brown, the third joint round, with short 

 pubescence, arista blackish, two times as long as the third joint, minutely 

 pubescent. Cheeks at the middle one fifth as deep as the eye-height, the 

 vibrissae not larger than the oral hairs. Anterior dorsocentrals scarcely larger 

 than the adjacent setulae, acrostichals in four very irregular rows ; one sterno- 

 pleural and one mesopleural bristle. Last segment of the abdomen transverse 

 and polished, the ovipositor short, broad, depressed and deeply scabrous, 

 margin and fringe of calypteres dusky. Wings nearly hyaline, veins brown, 

 the fourth vein ending just beyond the wing tip, its sections about one to 

 twenty, the sections of the fifth vein proportioned about one to five, the anterior 

 crossvein at two thirds the length of the discal cell. 



One specimen, Avon, Idaho, July 26, 1912.

MISCELLANEOUS NOTES. 



Drosophila repleta Woll. — This strikingly colored fly, better known 

 in America as D. punctulata Loew, has an extended tropical and sub- 

 tropical distribution and has even been taken in New York City. 

 Specimens recently determined through the kindness of Professor J. 

 M. Aldrich, Moscow, Idaho, show that this species was taken in 

 Albany in September and October, 1908, and also reared the preceding 



1 Agromyza tritici Fitch is apparently closely related.
