has the antennae longer, and with longer 2nd joint, the 

 basal portion of the thorax more elongate, and the 

 raised lines on the 1st dorsal segment more elongate. It 

 is smaller and more slender than B. dissimilis, and has 

 the 2nd joint of the antennae longer and stouter than the 

 3rd, instead of the two being subequal, as is the case in 

 B. dissimilis, and the head is quite without the two large 

 transverse depressions that are so conspicuous in the 

 latter species. 



Three specimens were found at Kashiwagi on the 

 18th June, 1881. 



Batrisus fragilis, n. s. 



Eufescens, nitidus, evidenter pubescens, antennis 

 pedibus palpisque testaceis ; cajjite anterius fortiter 

 punctato, 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, 

 abdomino segmento secundo dorsali in medio paulo 

 quam ad latera longiore, tertio ad basin linea transversa 

 depressa ; segmento ultimo ventrali sat elongato, in 

 medio utrinque obscure carinulato, carinulis setulosis, 

 inter eas depresso. 



Antennae slender; basal joint short; 2nd longer than 

 the 3rd ; 7th rather longer than those adjacent to it ; 

 club slender, rather strongly pubescent ; the 9th joint 

 longer than broad ; 10th also slender in the female, 

 rather broader in the male ; terminal joint acuminate. 

 Head with a slight transverse channel marking off the 

 clypeus, which is coarsely punctate, the vertex very 

 little punctate. Thorax rather elongate, slender. Ely- 

 tra quite without angle at the shoulder ; the discoidal 

 stria deep and elongate, but not quite reaching the 

 extremity. 



Of this species Mr. Lewis found fourteen specimens, 

 seven of each sex.
