collection as the type male of C. hhnaculata, but does not correspond to- 

 the description. A male of another species, marked C himaculata type, is 

 doubtless the true tj^pe.

c5' . Niger : clypeo, fronte, pronoto, scutello macula utrincjue, segmento 

 dorsali secundo basi, tertio fascia lata apicali, tibiis tarsisque anticis- 

 ferrugineis ; alis f tisco-hyalinis, stigmata testaceo ; clypeo convexo, apice 

 truncato ; mesopleuris subtviberculatis ; segmento abdominali primo fere

 segmento mediano area basali punctata. 



Long. 9 mm. 



c? . CljqDeus convex, truncate at the apex, a little longer than the great- 

 est breadth ; antennas inserted at least half as far again from the anterior 

 ocellus as from the base clypeus ; second joint of the flagellum nearly 

 half as long again as the third, apical joint scarcely as long as the pen- 

 ultimate and slightly curved. Eyes parallel ; the posterior ocelli more than 

 half as far again from the eyes and from each other. Mesopleurce sub- 

 tuberculate ; first abdominal segment about half as long again as broad ; 

 second ventral segment without a raised area at the base ; pygidial area 

 nearly twice as long as broad, the sides parallel. Head and thorax,, 

 including the enclosed area at the base of the median segment, very finely 

 and closely punctured ; abdomen rather more coarsely punctured ; meso- 

 pleurtB rugose. First recurrent nervure received at onethird from the 

 base of the second cubital cell. 



Habitat — Khasi Hills (Coll. Pot/mei/.) 



This species is distinguished from nebulosa, Cam., by the longer petiole. 

 The type of canaiiculata is without the two fulvo-ferruginous spots on the 

 scutellum, but I cannot see that it differs otherwise, nor does Cameron 

 give any other difference in the unfortunate paper in which both are 

 described. He is capable of far better work, as is shown by his paper on 

 the same genus in the memoirs of the Manchester Society for 1890.
