The European P. notatus is rather common in the pine-woods of 

 intermediate elevations in Madeira proper, and it exists likewise in 

 a small patch of firs which have been planted within a comparatively 

 recent period on the summit of the Deserta Grande. Inasmuch 

 therefore as it is clearly a mere introduction into the latter island, I 

 am inclined to suspect that it may perhaps originally have been 

 Imported even into Madeira along with the pines, which have now 

 become large trees, and which clothe a considerable portion of the 

 mountain-slopes in certain districts. It has not yet been detected 

 in the Canaries.

feature and one which is equally indicated, according to the sex, in the picipes, 

 Sf event, and granulicollis\, and the thorax granulated." This last, of course, 

 has to be duly considered ; but I believe that the supposed difference in sculpture 

 is more apparent than real ; for even the picipes has each of its large punctures 

 furnished internally with a little prominence, or tubercle (out of which arises a 

 short hair), and when the punctures are very closely packed together (as is the 

 case in the smaller individuals) these inner tubercles become a trifle more deve- 

 loped, and give the surface rather more the appearance perhaps of being granu- 

 lated than punctured. But I am exceedingly dubious as to the value of such a 

 character, which will probably be found to merge gradatim into the other.
