A specimen from Barrackp... more »ore agrees with Smith's description so far as it goes. It is fully one line longer ; the hair on the thorax is longish and tolerably thick ; the clypeus is broadly transverse at the apex, the sides being angled ; the mesonotum is furrowed in the centre ; the legs are thickly pruinose; the second cubital cellule at the top is about one-fourth shorter than the third, and about equal in length to the space bounded by the second recurrent and second transverse cubital nervures ; the third cubital cellule is almost equal in length at top and bottom, and the third transverse cubital nervure is sharply elbowed a little below the middle. Ammophila Atripes, Smith. The Barrackpore specimens of this species, as named by Smith, are uniform in coloration—black, the second joint of petiole is red beneath, the first joint black, the other segments steel-blue; the wings more or less fuscous, the nervures black. Face and clypeus densely covered with silvery white pile; apex of clypeus transverse, the sides rounded ; vertex and front with scattered punctures, shining. Pro- and mesonotum strongly transversely striolated; meta- notum more closely and not so strongly; scutellum and post scutellum longitudinally striolated ; pleurae rugose. The pubescence on the thorax is short and cinereous; the abdomen is thickly pruinose. At the top the second cubital cellule is about one-half the length of the third, and a little more than the space bounded by the second recurrent and second transverse cubital nervures ; the third cubital cellule is nearly equal in length at top and bottom ; the third transverse cubital nervure is elbowed near the mid...« less
