46 CANARIAN COLEOPTEEA. 



The single example from whicli the above description is drawn-out 

 was captured in Teneriife by Dr. Crotch, during the spring of 1862 ; 

 but he has, unfortunately, no note as to the precise locality. It may 

 at once be recognized from the P. alticola by its very much smaller 

 size and less elongate outline ; by its head being darker, whilst the 

 rest of the surface is, on the contrary, still paler or more rufescent ; 

 by its prothorax being more quadrate, though rather rounder at the 

 sides and more narrowed behind (and therefore with the posterior 

 angles more obtuse), as well as convexer on the fore disk and less 

 sinuated along the basal edge ; and by its elytra being much more 

 finely alutaceous, more delicately striated, less acutely porrected at 

 the shoulders, and with the raised line between either humeral angle 

 and the scutellum both less elevated and less curved.

Habitat Lanzarotam et Fuerteventuram, in locis intermediis, rarior. 



The P. crenatus, which is recorded in Portugal and Sicily (indeed 

 I possess it from the former), is foimd, though somewhat rarely, in 

 Lanzarote and Fuerteventura, — in both of which islands it was taken 

 by Mr. Gray and myself, during January 1858. It seems to make 

 its appearance after the winter-rains, and to occur at intermediate 

 elevations. My Lanzarotan specimens were all collected from be- 

 neath stones, in the open, cultivated fields on the mountains imme- 

 diately to the south of Haria.
