I have never seen this species Mr. Waterhouse says of it 

 that it may be distinguised from A. Bohemani and morosus, by 

 the thorax being distinctly ridged at the sides, and proportionally 

 smaller and less convex.

This insect also is unknown to me. It is evidently a Ciibl- 

 corhynchus, but very distinct from all of the genus which I have 

 seen, in having two large tubercles near the apex of the elytra. 

 Mr. Waterhouse makes mention of a variety of this species in 

 the British Museum, in vv^hich the tubercles in question are very 

 little more developed than those whicli pi-ecede them.
