Nomia foxii, D. T. 



Fox records this from Colorado, New Mexico, and S. Dakota. 

 Specimens are before me which were collected by Prof. C. H. T. 

 Townsend at Turkey Tanks, Arizona, July 17th and 18th. The 

 male, not known to Fox, differs little from Ashmead's description 

 of wickhamii. The hind femora are thickened ; the hind tibiae 

 triagonal, greatly enlarged distally, testaceous, with a black 

 blotch on each face, and the outer apical corner black ; the hind 

 tarsi with the basal joint testaceous and flattened. Flagellum 

 ferruginous beneath. 



Nomia bakeri, n. sp. 



$ . Length not quite 10 mm., black, strongly and closely 

 punctured ; pubescence short, dull white, tolerably dense on 

 face, pleura, and post-scutellum, forming narrow bands on the 

 apical margins of the abdominal segments. Flagellum with a 

 dark ferruginous tinge beneath. Wings dusky yellowish, apical 

 margin broadly smoky ; stigma ferruginous, nervures dark 

 brown ; tegulaa transparent amber-colour ; femora black, anterior 

 femur with a ferruginous stripe in front, hind femora incrassate, 

 the basal half dark ferruginous ; tibiae ferruginous, hind tibiae 

 broadened to apex, but not so much modified as in N. foxii ; 

 tarsi ferruginous, hind tarsi mostly black except at base. The 

 face is broader below than in N. foxii, and the punctures of the
