CORYNODES ANGULICOLLIS. 23 



joints slightly shining, metallic greenish, the rest black, 

 opaque. Thorax broader than long, the disk very convex, 

 all the angles produced into a short tooth , the sides 

 straight from the base to the middle, above the latter 

 obliquely narrowed towards the apex , forming a distinct 

 angle at the lateral margin; surface closely covered with 

 very deep oblong punctures , which are more distantly 

 placed towards the base; an obsolete oblique depression is 

 visible at each side near the posterior margin. Scutellura 

 small, oblong. Elytra parallel, robust, distinctly depressed 

 below the base, with a narrow margin from the shoulder 

 to the apex , metallic green , with a purplish reflection 

 towards the sides; surface finely geminate punctate-striate 

 near the suture, rather coarsely and irregularly punctured 

 near the sides, where the interstices, especially near the 

 shoulders, are somewhat rugose; punctuation towards the 

 apex more finely impressed. Underside purplish-blue , thinly 

 covered with fulvous hairs. Tibiae entire. Claws appendi- 

 culate. 



A single specimen from Doesoen Tengah (Sumatra-Ex- 

 pedition). 



Amongst those species , in which the epistome is conti- 

 guous with the front, the present one is at once separated 

 by the angulate sides of the thorax , its coarse punctuation 

 and the gradually thickened antennae.

 striate, with an obsolete tubercle below the shoulder. — •
