 C. paUersoni, sp. n., and C. {Eusemion) corniger. Walk., all exhibit the same type 

 of wing pattern, but they can be separated very easily by antennal and other 

 characters.

 (except for a pale postero-median edging to the pronotnm, including the scutellum), 

 refringent, metallic deep-green, with a slight play of colour, a little blue on the axillae 

 and sides of the scutellum. Flattened portion of the face above the toruli dull 

 cupreous or purplish ; clypeus, genae and lower angles of the frons, and the mid line 

 between the toruli shining metallic blue or violet-black ; antennae black with 

 violaceous reflections. Thoracic sternum, propodeon, abdomen and ovipositor
