Cameron, On some undescribed Indian Bees. 51 



Front and vertex closely, but not nearly so strongly punctured 

 as the clypeus ; there is a distinct furrow below the anterior 

 ocellus. Metanotum closely, strongly aciculated , the base with 

 some moderately large , clearly separated punctures. Abdomen 

 opaque , impunctate ; the pygidium bare. Apical joints of tarsi 

 rufo-testaceous ; the calcaria white. 



Tetr alonia claripennis sp. nov. 



Black, a triangulär mark, the apex above, longer than it is 

 wide below , in the middle of clypeus , commencing above the 

 middle and extending to the apex and the labrum pale yellow, 

 the apical 4 joints of the tarsi rufous ; wings clear hyaline, the 

 nervures blackish, the 2"^"^ abscissa of radius as long as the 1^*, 

 and about one fourth shorter than the 3'''^; both the recurrent 

 nervures are received shortly before the transverse cubitals. Cly- 

 peus closely, strongly punctured, almost Square, the apex furrowed, 

 transverse. Labrum closely covered with long white hair. Meta- 

 notal area clearly defined , closely, somewhat strongly punctured, 

 except down the centre and along the apex and sides. Punctu- 

 ration of mesothorax weak , the sides more closely than the 

 notum. Puncturation of abdomen close, distinct, not very strong. 

 Pygidium longer than wide , densely covered with pale fulvous 

 pile, closely longitudinally striated ; the apex distinctly narrowed, 

 rounded at the end. d'. 



Length 10 mm. 



Ferozepore. March (N u r s e). 



The antennae are fully longer than the body; the pubescence 

 on the thorax appears to be longer and not quite so dense as 

 usual. Characteristic is the distinctly narrowed apex of the 

 pygidium and the triangulär mark on the clypeus. 



Tetr alonia duv ancelii Lep. 



Both sexes of this species have been taken by Col. N u r s e 

 at Ferozepore in March and April. The ? has not been de- 

 scribed. It has the lower two-thirds of the clypeus, the labrum 

 and the base of the mandibles yellow ; the apices of the ab- 

 dominal Segments are also yellow. The 1** and 2"^*^ abscissae of 

 the radius are equal in length and shorter than the 3'''^. The 

 underside of the flagellum is dark rufous. In the only cf I have 

 seen the pygidium has the apex narrowed. 



Megachile obtusata sp. nov. 

 Black , the hair on the head , thorax and legs white , that 

 on the underside of the metatarsus rufous, the apices of the ab-
