tubercles ; inflexed margins irregularly punctured. Legs with dense 

 grey scaling, variegated with brown spots and with short sparse 

 setae ; tarsi comparatively short and broad, posterior pair with joint 1 

 evidently longer than 2, joint 2 of intermediate pair distinctly 

 transverse.

Type in the British Museum. 



Nearly allied to B. quadrata, Wied., from which it may be dis- 

 tinguished by its tarsal structure. The 3 examples which I have 

 associated with the type differ from it in having the thorax longer, 

 the shoulders narrower, and the elytra more carinafce. It seems 

 very probable that these characters are sexual, and they are here 

 provisionally treated as such.

Long. 4J-71 ; lat. 2i-3f mm. 



Colour usually dark brown above, with the declivity and inflexed 

 margins paler ; along the suture is a broad stripe composed of 

 alternate dark and pale patches, the median dark patch being deeply 

 emarginate posteriorly ; but these markings are liable to become 

 more or less obsolete. 



Head uneven, with large confluent punctures, but without distinct 

 carinae. Bostrum shallowly punctured, the dorsal margins sub- 

 costate and with a low central carina. Prothorax dorsally as long 

 as broad in the ^ , slightly transverse in the $ , the sides scarcely 

 rounded but gently sinuate near apex, the ocular lobes not dilated ; 

 upper surface with large confluent punctures and with a broad 

 central furrow, which is usually bounded by two low carinse, the 

 anterior impression trifoveate, and the sides deeply punctured. 

 Elytra oblongo-ovate, the shoulders narrow and oblique, sides 

 moderately ampliated, broadest at middle, the apical declivity 

 rounded dorsally ; punctuation more or less irregular, deeper at 

 the lateral inflexion (which is without sulci), but becoming more 

 obsolete toward the extreme margin ; interval 6 with a row of small 

 tubercles, often very much reduced ; the tubercles on interval 4 com- 

 mencing about middle and gradually increasing posteriorly, that on 

 the top of the declivity being distinctly larger than all the others ; 

 interval 2 with only two or three small tubercles at the declivity, and
