Batrisus japonicus, n. s. 



Eufescens, nitidus, evidenter pubescens, antennis 

 pedibus palpisque testaceis ; capite anterius fortiter 

 punctato, vertice bifoveolato ; prothorace impunctato, 

 dorso canaliculate), lateribus longitudinaliter impressis ; 

 elytris ad basin quadrifoveolatis, stria discoidali elongata. 

 Long. 2 mm. 



Mas, tibiis intermediis apice interno mucronato, abdo- 

 mine segmento secundo dorsali margine posteriore la- 

 mina magna depressa, e setulis adpressis composita. 



This species almost exactly resembles B. fragilis, 

 except in the characters of the male, but these are so 

 different as to leave no doubt of specific distinction 

 between the two ; the dense scale-like patch of the 2nd 

 dorsal plate is very conspicuous in B. japonicus, and 

 probably covers a transverse depression on the following 

 segment, but this cannot be seen : the terminal ventral 

 segment is not elongate, and is nearly simple. 



Six males (but no female) were found of this species ; 

 an individual from Hakone (not found with the male 

 from there) may possibly be the female of B. japonicus, 

 although it presents scarcely any difference from the 

 corresponding sex of B. fragilis. 



Hakone and Miyanoshita ; also Nagasaki. 



Batrisus fallax, n. s. 



Rufescens, nitidus, evidenter pubescens, antennis pedi- 

 bus palpisque testaceis ; capite anterius fortiter punc- 

 tato, vertice bifoveolato ; prothorace impunctato, dorso 

 canaliculato, lateribus longitudinaliter impressis ; elytris 

 ad basin quadrifoveolatis, stria discoidali elongata. 

 Long. 2 mm. 



Mas, tibiis intermediis apice interno mucronato, abdo- 

 mine segmento tertio dorsali fovea transversa magna et 

 profunda, cujus margine posteriore curvato, in medio 

 vix elevato, segmento secundo margine posteriore in 

 medio utrinque setulis depressis sat elongatis ; segmento 

 ultimo ventrali haud elongato, in medio utrinque carinu- 

 lato, carinulis obscure setulosis, inter eas depresso. 



This species again is similar in all respects, except 

 the male characters, to B. fragilis and B. japonicus ; the 

 specimens are eight in number, and all are males,
