sparsely setose ; bluish black, the head nigro-feneous, the 

 basal joiuts of the aiiteinue obscurely rufesceiit, the pro- 

 thorax (au elongate black patch on the disc excepted) 

 rutu-testaceous. Head small, narrow, somewhat produced 

 anteriorly, the labruni concave, nearly as long as broad, 

 rounded at the sides ; eyes distant ; antennae short, slender 

 at the base, widened outwards, joints 8-10 serrate, 10 sub- 

 transverse, 11 concave within, barely as long as 9 and 10 

 united. Prothorax much wider than the head, about as long 

 as broad, uneven, polished on the disc, sparsely punctate 

 laterally. Elytra broad, long, widened to beyond the 

 middle, rounded at the tip ; densely, finely, rugulosely 

 punctate. Legs rather short. 



Length (excl. head) 10, breadth 4 mm. 



Hub. India, Manipur {Duherty). 



One specimen. This specii s resembles Prionocerus ccerulei- 

 pennis and P. bicolor in shape, but it has the antennse slender 

 at the base and joints 8-10 abruptly serrate ; the head is 

 small and narrow ; the prothorax is red, with a black, 

 anteriorly narrowed median vitta; and the elytra are broad, 

 dull, and bluish black in colour. I. submetallica, Pic (1911), 

 from Kandy, M'hich has the elytra red, except at the tip, 

 seems to be an allied form.

 Hills, alt. 1100 metres (^H. L. Andrewes). 



This species is easily recognizable by the very short fourth 

 joint to the antennae, the bluish-green head, elytra, under 

 surface, and legs, the testaceous prothorax, and the partly 

 testaceous basal joints of the antennae. The three females 

 from the Anamalai Hills in the Andrewes collection have 

 joints 5-10 of the antennae cyaneous, considerably widened, 

 and distinctly serrate, these joints, according to Bourgeois, 

 being broadly serrato-dilatate in the ^ ; his definition of 

 the ,? antenna as "subfiliform" is misleading. The sutural 

 angle of the elytra in ? is dentiform, as described by Pic.
