Tibet : Gyangtse (13,000 feet), June 1904 {H.J. Walton). 

 Collected on the Tibet Expedition, 1903-4-. 5 ? ? . 



The host of this species is probably Colletes sanctus, Ckll., 

 a long series of which was caught in the same locality at the 

 same time. 



The species may be readily recognized, by the unbroken 

 abdominal fasciae and the entire labrum. It would other- 

 wise seem to resemble E. transitorius, Eversm., var. serax- 

 ensis, Rad., from Transcaspia, and E. fallax, Mor, from 

 Algeria. In addition to the characters mentioned above, it 

 dirfers from the former in having the scutellum and tegulae 

 black.
