antennae, which are plano-convex dorsally and slightly concave 

 ventrally, subequal in length, each about three times as long as 

 broad, and each furnished Avith two whorls of long hair. The 

 spur of middle tibia rather longer than the corresponding first 

 tarsal joint. 



Cameron's genus Aseiria, placed by this author in the Eupel- 

 mince (Biol. Centrali- Americana, Hymeuopt., i. p. 127, pi. vi. 

 fia:. 13), seems, both from description and figure, to be a synonym 

 of Oerchysius.
