line visible behind the disk, hind angles nearly rectangular ; 

 the elytra finely but very evenly striate ; the antennae black, 

 first joint enlarged, others much smaller; the legs pale, or 

 pale with infuscate tibise and tliighs. 



This little species, the smallest of this series, is to be placed 

 next to C. albipilis, Cand. 



Hab. Torii-toge (alt, 4016 feet). Three examples. 



Cryptohypnus carinicoUis, sp. n. 



Parum latus, niger, Bitidus, griseo-pubescens ; thorace angulis 

 posticis divaricatis, carina marginem anticum attingente ; elytris 

 obsolete striatis ; antennis pedibusque nigris,

Black, shining, with greyish pubescence; the head finely 

 punctulate, frontal carina angulate anteriorly ; the thorax 

 rather more finely punctured than the head, angles scarcely 

 acute, but turning outwards, lateral carina strong and com- 

 plete ; tlie scutellum rather wide, acuminate behind ; the 

 elytra, in certain lights only are stria3 visible, interstices very 

 finely punctulate ; the antenna and legs are black, tlie former 

 being much more robust than in any of the minute species of 

 this series. 



This species and C. enipticu.<i, Cand., are the only two 

 known from Japan in wliicli the thoracic carina is continued 

 from the base to the anterior edge. In C. carmicollis it is 

 much more elevated than in C. elUpticiis and the antennje are 

 more robust. There is a specimen from Nikko with the 

 frontal carina semicircular ; it is possibly a closely allied 

 species.

 common.

 Cryptohypnus minutissimiis, Germ. ; Cand. M^m. Liege, 1873, p. 14. 



This species has been determined by Dr. Cand^ze ; it does 

 not appear in Heyden's Catalogue of Siberian species, and it 

 is the only European species said to be foimd in Japan.
