structure but less developed is seen in B luridtts). The flattened 

 space on the middle of the metasterjiuin is somewhat trapezoidal, 

 having its narrowest end directed backwai'ds, but not at all 

 passing the front margin of the hind coxae, and bearing a large 

 fovea in the centre. The basal third part of the lower face of 

 the four posterior and (obsoletely of the anterior) femora (as in B. 

 luridus) is nearly black and is opaque, densely and very finely 

 punctulate, and minutely pubescent. My three specimens are of 

 the same sex, apparently female ; the 5th ventral segment is 

 widely and somewhat squarely emarginate at the apex, each side 

 of the emargination forming a strong spine ; the 6th segment is 

 barely discernible, projecting from the crenulated base of the 

 emargination. 



Probably allied to B. ovi2}enniSj Fairm., (from Queensland), but 

 much larger, without elevated or impressed lines on the head, 

 with elytral interstices not flat, &c., &c.

In my type of this insect the prothorax is yellowish testaceous, 

 while the color of the elytra inclines to pale fuscous. The spot 

 on the prothorax is transverse, and occupies the middle third part 

 of the surface being about half as long as the whole segment, and 

 placed jusfc in front of (but not touching) the base. On each 

 elytron there is an elongate fuscous spot on the first interstice at 

 about a quarter of its length from the base, a larger and blacker
