80 Mr. G. R. Wateihouse's Notes, Sfc. 



but may at once be known by the two large acutely conical tuber- 

 cles which are situated on the elytra, at tlie part at which they are 

 somewhat suddenly deflexed behind. The granules on the thorax 

 are larger, and there are some small conical tubercles on this 

 part; viz. two near the middle of the posterior margin, another 

 at the posterior angle, and one again on the side of the thorax, 

 rather in front of the middle. I do not anticipate these will be 

 constant in all specimens of the species. On the elytra the minute 

 tubercles, commonly distinguished by the term granules, gra- 

 dually increase in size, so as at last to assume the form of small 

 pointed tubercles, and these latter are most distinct towards the 

 hinder part of the elytra, on the alternate interstices : again, in the 

 region of the shoulders, are some of the small tubercles.* The 

 abdomen has some very fine scattered punctures, and some, 

 equally scattered, scales beneath. 



I have a specimen of this insect from Swan River, and there are 

 two specimens evidently of the same species in the Collection of 

 the British Museum, but which differ from each other and from the 

 specimen described in certain particulars ; one forms the variety 

 B., already noticed, and the other has the two tubercles situated 

 towards the apex of the elytra, and belonging to the second inter- 

 stice, very little more developed than the tubercles which precede 

 them. 



I have named this species in honour of the accomplished Pre- 

 sident of the Entomological Society of Stettin.
