 rufo-testaceous, the tarsi paler ; the hinder coxae black 

 beneath; the fore femora slightly, the four hinder more 

 broadly, lined with black beneath. Wings hyaline; the 

 apex with a blackish cloud extending from the second 

 transverse cubital nervure to the apex ; dark in the radial 

 cellule, more obscure in the cubital ; the nervures blackish; 

 the stigma testaceous; darker along the upper border. 

 Petiole with a distinct, narrow neck, from which it becomes

 The only Indian species of Colletes may be separated 

 from the present as follows : — 



Vertex with "a few fine punctures": the median 



segment at base longitudinally rugose, the apex with the 



sides smooth. C. dudgeonii Bng. 



Vertex coarsely punctured, the median segment strongly 



reticulated; the sides of the apex transversely striated. 



C. dentata. 



Clypeus apparently closely and rather strongly 



punctured, but the surface cannot be properly observed 



from the matting of the hairs ; the front and vertex
