Of this pretty nondescript species, which is nearly allied to 

 P. thoracicus, I have seen only a single specimen contained in 

 the cabinet of the British Museum, and which, solely in con- 

 sequence of the wish expressed by me to describe and figure 

 the new unnamed species of Paussus contained in that cabinet, 

 was immediately designated by the manuscript name which I 

 have adopted above, although I regret to state, that the species 

 belonging to the neighbouring, and indeed I might add, to the 

 majority of the genera of insects contained in that national 

 repository, still for the most part remain unnamed and in con- 

 fusion.
