4.32 New species of Australian coleopterA, 



front with a small punctate space ; disc strongly elevated along 

 middle, and then abruptly cut away and irregular, the apex 

 strongly elevated; towards each side with a curved impression, 

 commencing near the base in a fovea, another fovea in the 

 middle connected with the lateral ones ; and several small 

 basal fovese ; without conical tubercles towards base. Elytra 

 rather short, with a fairly large impression between each side 

 and suture, from which a dorsal stria can be traced almost 

 to middle ; shoulders unarmed ; punctures sparse and racher 

 indistinct. Ahdonien on upper surface with feeble tubercles 

 somewhat obscuring the basal impressions ; lower surface feebly 

 flattened along middle. Legs rather long and apparently 

 unarmed. Length, 2mm. 



Hah. — N. S. Wales: Blue Mountains (E. W. Ferguson). 



The punctate latero-frontal spaces of the prothorax are 

 much as in B. ajjicicollis, but that segment, from the side, 

 appears to have two deep notches in front, the notches leaving 

 a strong, blunt, sublaminate projection in front, and an acute 

 projection between the front and middle (from certain direc- 

 tions, two acute projections can be seen). From directly in 

 front it appears to be triangularly elevated at apex, then with 

 two small acute elevations, and then with the middle strongly 

 raised and feebly notched. The prothorax of B. insignicolUs, 

 when viewed from the side, appears somewhat similar ; but 

 the notches are not so deep, it has no acute elevations, and 

 the frontal one is much smaller and less prominent; from 

 directly in front it appears very different. 



From some directions, the medio-lateral grooves of the 

 head appear to be regularly and deeply cut ; but, from others, 

 each appears foveate at its base, with a narrow groove opening 

 out in front. On the type, only six joints of each antenna are 

 left : they are rather thin, the second joint as long as the first 

 (but, from some directions, appearing decidedly longer), and 

 the fifth slightly longer than the fourth or sixth. I have 

 described the specimen, however, as the sculpture of the pro- 

 thorax is very peculiar.
