cler blackish, in some specimens with less reddish. Wings inluscate 

 on outer part, yellowish toward the base. Length 5-.5|""". 



Eight specimens from California (O. T. Baron) and one, which 

 appears to be the same, from North l*ark, Colorado, (G. B, Grinnell).

Oncomyia loraria Loew, Ceutur., vii, 74. 



Translation: "(J ?. Black, lightly whitish pollinose, antenme 

 black, below red, legs in large part black, second joint of the pro- 

 boscis exceeding the first a little in length. Long. corp. lf-2^ lines; 

 of wings l^^-lf lines." 



" Black, lightly whitish pollinose, moderately shining. Head di- 

 lutely yellowish, face with a white lustre. Front sordid reddish, near 

 the vertex black-fuscous or black. Antenna? black, reddish below 

 except the tip (' hiteribus adversis praoter marginem superum et prae- 

 ter apicem, aversis in margine infero rnfis'). Second joint of proboscis 

 a little longer than the first. Occiput black. On the dorsum of the 

 thorax three lines denuded of pollen are indistinctly visible. Legs 

 black, knees and base of posterior femora always, anterior coxa?, base 

 of front and middle femora, and base of all the tibije and front joints 

 of all the tarsi frequently testaceous. Wings cinereous, or dilutely 

 infuscate, base narrowly lutescent. (New Hampshire)." 



A single specimen from Connecticut I would identify with this, 

 except that the second joint of the proboscis is considerably shorter 

 than the first, a character, however, that seems to be of little value ; 

 the smaller size, Ci-4^'"'", would seem to prove its distinctness 

 from 0. Baroni.
