Type.— Csit. No. 13422, U.S.N.M. 



Resembles the Indian S . fumipennis Smith in most respects, but the 

 wings are more broadly pale at base, and the abdomen shows more 

 black. S. oriundus Vachal, from Japan, differs by the proportions of 

 the antennal joints and the lighter wings. There is much resem- 

 blance to the European 8. gihhus. The antennae are quite of the 

 gihhus type, but the fourth joint is considerably shorter. 



SPHECODES MONTANUS Smith. 



Bingham (Fauna of British India) states that the wings are hya- 

 line, but I have examined Smith's type and find them pale fuscous.

 lower part of cheeks with a large beard of white hair; dark hair of 

 thorax above scanty; clypeus with a great triangular shining black 

 excavation, strongly keeled down the middle, and bounded on each
