Indo- Chinese Hymenoptera. 485 
sparsely punctured, vertical area longer than its greatest 
breadth, slightly narrowed anteriorly; the head swollen 
behind” the eyes. Mesonotum obsoletely punctured, the 
median lobe divided from base to apex by a deep groove in 
which lies a low carina. Scutellum coarsely punctured, 
raised into a conical tubercle ; mesopleuree coarsely rugulose. 
Abdomen smooth. ‘The apical fuscous mark on the fore 
wing is paler than the median fascia and occupies almost the 
whole of the fourth cubital cell and the extreme apex of the 
radial cell. The median fascia crosses the wing from the 
basal half of the stigma and does not extend apically beyond 
the second transverse cubital nervure. ‘The discoidal nervure 
is separated from the base of the cubital nervure by a distance 
about equal to the length of the first transverse cubital 
nervure,

Differs very strongly in colour from C. stkkimensis, 
Konow, the only other known species of the genus, especially 
in the fasciate wings; but the neuration and structure do not 
differ appreciably.
