anteriorly with an arched stria, and the edge of tliis plate is 

 feebly bowed in outline ; from the base to beyond the middle 

 is a median cuneiform depression (e. g. A. sulcipetine) , or the 

 limit of the depression is indicated by two strife (e. g. A. 

 tihiale) ; the legs are slender, and in two species the tarsi 

 alone give a sexual character. 



Ascaphium sulcipenne^ sp. n. 



Angustato-ovatum, nigrum, nitidum ; ore, antennis pedibusque rufis ; 



elytris striis profundis et punctato-striatis. 

 L. 6| miU. 



Narrowly ovate, black, shining ; epistoma, mouth-organs, 

 and antennae reddish ; the head irregularly punctulate between 

 the eyes, neck smooth ; the thorax tinely and sparsely punc- 

 tulate on the disk, nearly smooth behind the transverse 

 punctures ; the elytra — stria3 seven, very deep, with a single 

 row of punctures along each, the sutural stria continues in 

 the form of punctures along the base, two strise next to the 

 sutural are a little abbreviated apically, the sutural margin is 

 a little elevated ; the legs are without any conspicuous differ- 

 ences in the male, but the tarsi are slightly wider and serve 

 to distinguish the sexes. 



Hah. Nikko and Miyanoshita. Scarce, six examples only. 



Ascaphium. tihiale^ sp. n. 



Angustato-ovatum, nigrum, nitidum ; elytris punctato-striatis ; tarsis 



rufis, c? tibiis anticis lougioribus. 

 L. 5-5| mill. 



Elliptical, black, shining, mouth-organs and tarsi reddish ; 

 the head distinctly but not densely punctured between the 

 eyes, neck nearly smooth ; the thorax punctured like the 

 head, but less densely ; the elytra punctate-striate, but much 

 less deeply than in A. sulcipenne, the outer stria punctiform 

 and evanescent ; the sutural continues along the base, the 

 two stria3 next the sutural are of equal length and shortened 

 before the base ; the pygidium rufous at apex ; the legs in 

 the male are elongate and swollen rather nearer the tarsi 

 than the middle. The five apical joints of the antennae are 

 black, the others pitchy red. 



Distinguished from A. sulcipenne by the smaller size, 

 black legs, elytral stride much less deep, and by the mascu- 

 line character in the tibise. 



Hab. Miyanoshita, Subashiri, Nikko, and Oyayaraa. Not 

 uncommon.
