1.28 THE CANADIAN ENTOMOLOGIST. 



segments. Legs with white pile, the color of the tarsi less dark. Wings 

 nearly hyaline, the stigma luteous. 



One specimen, Arizona, (Prof. Comstock). 



Cyphomyia, n. sp. 



Five male specimens from Jamaica differ from the described species, 

 except perhaps varipes Gerst., the description of which I do not have 

 access to. The base of the third joint of the antennse, and the scutellum, 

 are red, and all the metatarsi, except the tip, light yellow. Otherwise 

 steel-blue black. The eyes pilose. 



Nemotelus tmicolor, Loew. 



Two specimens from Pennsylvania. In one of them the two basal 

 joints of the antennae are yellowish. Another from Arizona (Prof Com- 

 stock, No. 52) I cannot distinguish. 



Nemotelus crassus Loew. 



Three specimens from Western Kansas agree with the description of 

 this species, but are somewhat smaller. 



Pachygaster pulchris Loew. 



Two females from Montana differ but little from eastern specimens. 

 The femora have only a blackish ring in their middle.

Odontomyia flava Day. Proc. Acad. Nat. Sc, 1882, 76. 



The type specimen in my collection is partly destroyed by Anthreni, 

 I give as complete a description as it will permit.

 yellowish spots below, clothed with light colored pile. Dorsum of thorax

 narrow yellow margin and with two slender, broadly interrupted, yellow, 

 posterior cross-bands (on the second and third segments), venter yellow. 

 Legs yellow ; femora at their base, and the distal part of the tarsi brown, 

 the tibiae in their middle with a brownish ring. Wing hyaline. Veins
