L. 7-8 mill. 



The type of this species has an a3neou3 tinge, but in a 

 series of eighteen specimens I do not observe another with 

 this colour. There is one example also with the antennae 

 wholly red. 



Hah. Yokohama, Kii, Miyanoshita, Oyama, Oyayama, 

 and ITagi [Hiller). 



Corymhites gratus^ sp. n. 



Angustatus, parallelus, obscure aeneus, opacus ; thorace creberrime 

 ocellato-puuctato, canaliculato, angulis posticis haud carinatis ; 

 elytris densissime rugoso-punctatis ; antennis nigris ; pedibus rufis, 

 tarsis infuscatis. 



L. 11-12 mill. 



Narrow, parallel at sides, obscurely seneous, opaque ; the 

 head densely punctate, punctures ocellate, frontal carina 

 smooth ; the thorax punctured like the head, with broad 

 median channel, posterior angles turned outwards, somewhat 

 acute in male, rather obtuse in female ; the scutellum densely 

 punctured like the elytral interstices ; the elytra punctate- 

 striate, striae finely cut, interstices densely punctured and 

 transversely rugose ; the antennae serrate, joints longest in 

 male, otherwise dift'ering little in the sexes, black ; the legs, 

 thighs, and tibiaj clear red, tarsi dusky. 



This and the five following species are narrow and form a 

 section in the genus distinct from the others from Japan.

 Junsai.
