152 HYMENOPTERA FROM SARAWARK, 
the spiracles, the elongated areola, two oblique marks on the 
apex of the metanotum outside the posterior median area and 
the apices of all the abdominal segments (the line on the 2nd 
being broader than the others), pallid yellow. Mesonotum dis- 
tinctly and irregularly punctured, except at the apex; the scu- 
tellum is more strongly punctured, with a smooth line in the 
middle on the basal half. Metanctum strongly, deeply and 
irregularly punctured; the basal arez on the base and inner sides 
smooth; the areola has two elongated closely punctured spots in 
the centre; the posterior median area is stoutly, transversely 
striated, as is also the spiracular area beyond the spiracles. Pro- 
and mesopleure smooth; the meta- above the keel closely 
rugosely punctured. Petiole smooth and shining; the 2nd 
and the 3rd segments are closely punctured, the 2nd mort 
strongly than the 3rd; their base closely longitudinally striaded 
in the centre; the gastrocoeli smooth and shining. 
The colouration of the body is almost identical with that of 
C. robusta, Cam., but that species may be known from it by the 
four front legs being without black; andthe hinder femora are 
rufotestaceous, with the apical third black.
