If Bingham's fig. 127 (/.r., p. 408) represents the labium of 

 C. dtidgeo7iii, then that of the species here described differs 

 from it in the labium being much wider than the mentum, 

 and more widely and deeply divided at the apex. The 

 same remark applies to Smith's figure {Cat. Hyin. Ins., i., 

 pi. I., f i). Bingham makes no mention of the fore wings 

 having an appendicular cellule, nor is one indicated in his 

 figure. In C. dentata the appendicular cellule is quite 

 distinct, but open at the apex. The head and thorax are 

 not very pubescent for a Colletes, but this may be through 

 wear and tear. The wings vary in tint. 



APID^. 



Halictus TORRIDUS, Sp. nov. 



Long. 5-6 mm. 



Hab. Poona ( Wroughton). 



In Bingham's table {I.e., p. 421) it comes in at '' C. 

 Enclosed space at base of median segment with longitu- 

 dinal striae, b^. Abdomen impunctate," which contains two 

 species; — H. timidus, which, differs in having the abdomen 

 and legs rufo-testaceous, and the Burmese H. gutturosus, 

 which differs in having the eyes only very slightly con- 

 vergent below; while here they are very distinctly conver- 

 gent below ; the pubescence on the head and thorax is 

 "thin;" here it is dense and long. 



Head closely and distinctly punctured in front ; the 

 clypeus thickly covered with depressed, white pubescence; 

 the front, vertex, and hinder parts with the hair longer, more 

 erect, and not quite so dense ; eyes distinctly converging 

 on the lower side, the space separating them there being 

 about half the length of the vertex ; they have a distinct 

 curve near the top on the inner side. The face, below the 

 antennae in the centre, projects ; the projection being wider 

 at the apex, where it is clearly separated from the clypeus, 

 which is as long as the space between its base and
