female agrees in coloration, punctuation, and clothing with 

 the male. 



Differs from A. nigripes in being longer, in having the 

 hair on the thorax less dense and shorter, the clypeus more 

 rounded at the apex, the mesonotum with the central furrow 

 less distinct, the wings darker, and with black nervures. 



Barrackpore — common. 



B. mesoiwtum punctured. 



Ammophila Vischu, j/. nov. 



Nigra, nitida, punctata; apice petioli, abdouiinisque 

 segmentis i — 2, nifis ; alls fuscis. Long. 22 — 24 mm. 



Antennae stout, microscopically pilose. Face and 

 clypeus covered with a silvery white pubescence ; the front 

 and vertex bear long fuscous hair. Clypeus broad, flat, the 

 apex margined, truncated ; sparsely punctured. Front 

 depressed ; a distinct furrow down the centre ; rather 

 strongly punctured ; the vertex with the punctures more 

 widely separated. Thorax strongly punctured, the pleura; 

 and metanotum rugose ; scutellum with the punctures 

 larger and closer than on the mesonotum ; post-scutellum 

 rugose. Mesonotum with a distinct furrow, which becomes 

 wider towards the apex, where it is nearly filled up by a 

 keel. The pubescence is long and cinereous, long and dense 

 on the pleurse ; sparser above. The tubercles, an oblique 

 stripe on the pleura; and the middle segment laterally, 

 densely covered with silvery pubescence. Second segment 

 of petiole stout ; the extreme base black. Second segment 

 above wider than the space bounded by the first recurrent 

 and first transverse cubital nervures ; the third cellule much 

 narrowed at the top, usually there not one-fourth of the 

 length of the bottom. Tegulae black. 



The male has the clypeus produced and rounded at the 

 apex, and is, as well as the face, densely covered with 

 silvery pubescence.
