B. niger, angustulus, pedibus tenuibus fusco-testaceis ; oculis for- 

 titer prominulis ; prothorace elongate, elytris angastiore, subtili- 

 ter sat crebre punctato, subtiliter pubescente ; elytris fere opacis, 

 leviter striatis, sed striis perspicue punctatis, brevissime pube- 

 scentibus ; antennis articulo tertio quam secundus fere minora.

The black colour, slender legs, and peculiar form of the 

 thorax are quite sufficient characters to distinguish this little

This insect was sent from Auckland by Mr. Lawson ; and 

 I have recently received an individual taken at Tairua, and 

 with No. 40 attached, from Captain Broun.

B. colore variabilis, rufescens, plus minusve infuscatus, elytris indis- 

 tincte fusco-vittatis, abdomine nigricante, antennis fuscis, basi 

 testacea ; angustulus, minus nitidus, evidenter pubescens ; thorace, 

 crebre minus subtiliter punctato, augulis posterioribus elongatis, 

 acutis, bene divergentibus ; elytris sat profunde striatis ; antennis 

 articulis secundo et tertio vix abbreviatis. Long. 4| m. m. 



This little species has much the appearance of a small 

 Betarmon piciijes, the sculpture, pubescence, general form, and 

 colour being all somewhat similar.
