fringe yellowish. Abdomen shining, the surfaces of segments 2-4 

 granulose and less glossy than fifth; second and fifth segments elon- 

 gated. Legs black; covered with short hairs, the ventral surfaces of 

 femora bristled. Wings whitish, veins yellowish, costal setulae black, 

 carried, as usual, to end of second vein; venation almost identical 

 with that of Milicheilla lacteipennis , the third and fourth veins being 

 distinctly convergent at their apices.

Locality. — Harlingen, Texas, "reared from wild tuber," April, 1909

The female is similar in most respects to the male, but the frons is 

 distinctly broader and the halteres are generally pale yellow. In 

 all there are eight specimens before me which were labeled Agromyza 

 aeneiventris Fallen, and may have been recorded under that name. 



Genus PHOLEOMYIA Bilimek. 



Pholeomyia Bilimek, Verh. zool.-bot. Gea. Wien, 1867, p. 903. 

 Rynchomilichia Hendel, Wien. Ent. Zeitg., vol. 22, 1903, p. 250. 



Tlie species of this genus, which number 12 in Becker's paper 

 abeady mentioned, are recognizable from those in the genus Milichia 

 by the presence of bristles on the mesopleura, from ParamilicJiia by 

 the geniculated and elongated proboscis, and from Milichiella by the 

 absence of the incision in the posterior margin of the eye. 



I have seen three species belonging to this genus from North 

 America. Only one American species that I have seen can be 

 correctly referred to Milichia, though the genus has generall}^ appeared 

 in out lists as including most of those in Pholeomyia and Milichiella.
