and the middle joints may show a tendency towards fuscous 

 coloration. In size there is some variation. 



Ammophila nigripes, Smith. 

 A specimen from Barrackpore 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, SviitJi. 

 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 seg- 

 ments 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 middle. The
