Easily distinguished by its strongly oval shape, the thorax 

 being hardly contracted at the base, and no doubt belonging to 

 a different subgenus from the preceding and the following. The 

 head is exactly that of B. Klugii. The antennae have the 2nd 

 joint hardly shorter than the 3rd, and this and the following 

 subequal ; joints 1-4 are of a light yellowish, the rest of a brown 

 colour ; joint 3 of the maxillary palpi is of a dark, the remaining 

 ones and the labial palpi of a pale yellowish colour. The labrum 

 is square, entire, and, with the rest of the mouth, brown. The 

 mandibles are furnished with 3-4 small teeth below the middle. 

 The ligula is broader than in any of the other species. The 

 thorax, besides in shape, is distinguished by having the fovese 

 removed from the basal angles towards the centre. The elytra 

 are impressed with seven distinct striae on either side, the first 

 of which runs down to the apex, where it falls in with the infra- 

 marginal one ; the rest decrease in length towards the margin, 

 and in depth towards the apex ; beyond the 7th another is just 

 traceable, and beyond this there is a deep inframarginal one. The 

 apex is impressed with the semicircular figure which distinguishes 

 all the species here enumerated, with the exception of B. opu- 

 lentum and truncatum. The colour of the insect is a dark, bright 

 metallic green, variegated with four large yellow spots on the 

 elytra ; two of these are near the shoulder and of oval shape, 

 the other two near the apex and oblique ; the apex is of a dirty 

 yellowish colour. The lower part of the insect is of a pitch-colour, 

 lighter towards the apex ; the legs are yellowish, darker towards 

 the base.
