This species appears to agree in size, colour, and general 

 structure with the next, if indeed it be not specifically identical. 

 The chief apparent differences between its characters and the 

 description of P. ruber being, 1st, the formation of the head 

 and thorax of the two species, and which, as I have suggested 

 below, may not perhaps actually exist; and, 2ndly, the for- 

 mation of the terminal joint of the antennae, which must I 

 apprehend, on the other hand, be considered as indicative of 

 a distinct species. The circumstance of this species being pre- 

 served in the Linnean cabinet and actually attached to the 

 generic label in Linnaeus's hand-writing, — the original Linnean 

 species at the same time not being preserved in the cabinet, — 

 renders it necessary to state that this is not the P. microcephalus. 

 From Donovan's P. pilicornis it varies in colour, although when 

 the antennae are seen sideways, there appears to be some spe- 

 cific affinity.
