PHYTOPHAGOUS COLEOPTERA FROM BURMA 917 



deflexed, the sides strongly rounded and widened towards the 

 base, the surface subremotely impressed with small and still 

 finer punctures, the sides nearly impunctate ; scutellum broader 

 than long, impunctate; elytra subcylindrical , the base convex, 

 with a deep transverse depression , the entire surface closely 

 and strongly punctured, the punctures arranged in semi-regular 

 close rows, shoulders very prominent ; legs rugosely punctured 



Garin Gheba, February, March. 



Principally distinguished by the shape of the thorax, which 

 looks strongly narrowed in front when viewed from above, and 

 by the close and strong punctuation of the elytra. 



64 Ooryiiod.es Tbinnanicias, n. sp. 



Dark violaceous blue, the head strongly punctured, antennae 

 with the apical joints longer than broad; thorax transverse, 

 sparingly punctured, elytra without basal depression, closely and 

 strongly punctate-striate, claws appendiculate. 



Length 3 lines. 



Head strongly swollen at the vertex, the latter very strongly 

 but not very closely punctured , the front divided by a deep 

 longitudinal groove , the episteme also separated from the face 

 by a transverse groove, antennae extending rather beyond half 

 the length of the elytra, metallic blue, the terminal five joints 

 dilated, but longer than broad; thorax nearly twice as broad 

 as long , the anterior margin straight , the sides but slightly 

 rounded, the surface rather sparingly punctured at the disc, the 

 sides nearly impunctate ; elytra subcylindrical , not impressed 

 below the base or with a scarcely perceptible depression, strongly 

 and very closely punctate-striate; claws appendiculate. 



Garin Gheba. 



Amongst the smaller species of this genus, C. birmanicus may 

 be principally known by the rather long antennae, the want 

 of an elytral depression, their close and strong punctuation and 

 appendiculate claws.
