190 Mr. G. Lewis on 



scutellum somewhat acuminate behind, without an anterior 

 fovea ; the elytra punctate-striate, interstices evenly and finely 

 punctured ; the antennse and legs black, claws pale. Two 

 examples have an seneous tint on the elytra. 



Belongs to the same section as 0. sequens, Cand., but the 

 large size and the absence of the scutellar fovea will distin- 

 guish it at once. 



llab. Hakodate. Six examples in my collection and one 

 in the British Museum. 



Cardiojykorus niponicus^ sp. n. 



Elongatus, niger, nitidus, griseo-pubescens ; scutello postico parum 



producto, subacuminato ; autennis pedibusquc nigris. 

 L. ^ mill. 



Elongate, black, shining, pubescence grey; the head 

 rather small, finely and rather closely punctulate, frontal 

 carina semicircular ; the thorax gradually narrows from the 

 anterior angles to the middle, punctuation extremely fine, 

 hind angles obtuse, scarcely turning outwards ; the scutellum 

 impressed, not foveolate in front, posterior tip a little pro- 

 longed and pointed ; the elytra punctate-striate, interstices 

 convex and obscurely punctulate ; the antennte black, third 

 joint much longer than the second ; the legs black, with the 

 knees, ends of tarsal joints, and claws palish, last thickened 

 at base, not dentate. 



The shape of the scutellum and the relatively long third 

 joint of the antennaj are characters not seen in any other 

 species of this series. 



Hah. Nishimura. One example. 



Section II. Scutelku- fovea more or loss conspicuous. 



Cardiophorus opacus, sj). n. 



Niger, opacus, griseo-pubescens ; fronte carina iitrinque augulata ; 



elytris interstitiis dense nigosis ; antennis pedibusquc nigris. 

 L. O'miU. 



Elongate, black, very opaque, with short grey pubescence ; 

 the head closely punctured, punctures not very fine, frontal 

 carina angulate before the eyes ; the thorax punctured like 

 the head, widest behind the middle, hind angles blunt, not 

 turning outwards; the scutellum somewhat acuminate behind, 

 anterior fovea very distinct ; the elytra punctate-striate, 

 interstices very markedly rugose, giving an appearance of 

 complete opacity ; the antenna and legs black, claws pale, 

 not dentate.
