C. labiata, Fnh. — A trifle larger than viterrupta, with 

 the puncturatiou rather larger, closer and less regular; 

 clypeus in the S obsoletely tridentate at the apex, that of 

 the ? with its central portion much raised, free nearly from 

 the base, not narrowed towards the front, and only slightly 

 emarginate at the apex ; in the S the abdomen beneath is 

 clothed with very long hairs, and the penultimate segment 

 bears a very dense pencil of rigid golden seta3 on each side 

 at the apex ; this last character distinguishes it at once 

 from small individuals of arenaria ; all the femora in the c? 

 with a large black spot above. ;

The style of the neuration of the wings associates this 

 genus with Crabro and its allies, but I am not at all satis- 

 tied with its position. Its methods of flight are so like 

 those of A^tatus, Tachijtes,&c., as to suggest some relation- 

 ship with them. I have, however, left it here, not knowing 

 where better to place it. It may be at once distinguished 

 by the neuration of the wings, the anterior pair having 

 only one submarginal cell, which is apparently confluent 

 with the first discoidal, it is, however, really divided from 

 it by a hyaline nervure, which can be seen on close 

 examination, another very indistinct hyaline nervure closes 

 the third discoidal at its apex ; besides these alar charac- 

 ters, the wing-like appcudagos of the scutcUum and the
