 hardly longer than the recurrent; nervellus indistinctly inter-

Type 5 in the Indian Museum. 



This species is certainly most closely allied to C. perditor, 

 Forst., from which its smaller size and basally white hind tibiae 

 will distinguish it. 



The cf from Shillong probably constitutes the alternate sex, 

 since it differs only in its stramineous mandibles and tegulae, and 

 the entirely rufescent anus.

2 . A black species, with the abdomen narrowly in the centre, 

 and the anterior legs more broadly, red. Head black, closely 

 punctate, the face and clypeus with dense white pubescence; 

 palpi infuscate, and the mandibles centrally broadly red ; frons 

 sparsely and superficially punctate, centrally distinctly carinate. 

 Antennce immaculate. Thorax black; metanotum broadly but 

 superficially impressed centrally, more strongly punctate than the 

 mesonotum and closely trans -striate, but more sparcely so 

 apically ; basal area small and quadrate, emitting short oblique 

 carinae from its apical angles; propleurao nitidulous and irregularly 

 striate below ; metapleurae apically strongly and obliquely striate 

 above the unusually stout lateral cariuse ; metasternal carinae 

 stoat and distinct. Scutelhim convex and with sparse pale 

 pubescence, obscurely striate laterally. Abdomen black, with the 

 third segment almost entirely, and the second laterally, red. Legs 

 with the anterior tibiae and the apices of their femora dull 

 testaceous; hind legs black, with the apices of the tibiae dull 

 testaceous. Wings hyaline and iridescent, with the stigma and 

 nervures blackish ; areolet shortly petiolate, emitting the recurrent 

 nervure beyond its centre.
