NEW KECORDS OF BEES. 233 



Proteraner rhois, n. sp. 



(? . Length about 8 mm. ; like P. leptantld, but with a con- 

 siderably narrower, lighter-coloured abdomen, with the basal half of 

 the first segment black ; enclosure of metathorax typically irregularly 

 cancellate, not well defined (but in one Manitou specimen longitu- 

 dinally ridged) ; tegulfe with a distinct narrow whitish margin ; 

 abdomen well punctured throughout. 



Hah. Type from Kio Kuidoso, White Mts., New Mexico, at 

 flowers of Rhus glabra, July 21st (C. H. T. Townsend). Also 

 from Manitou, Colo., at flowers of Pdhes leptanthum, one April 

 28th and one May 10th (TF. P. CklL). Very distinct in appear- 

 ance, by the narrow, lighter red abdomen, but with no other 

 important character. The sculpture of the metathorax, distinct 

 enough in the type specimens of rhois and leptantJii, is quite 

 variable. The Rio Ruidoso locality has an altitude of about 

 6500 ft. ; Manitou about 6600 ft.
