Inhabits Madeira proper, occurring in the moist sylvan di- 

 stricts of intermediate altitudes ; detected by myself at the base 

 of the lofty perpendicular rocks near the upper extremity of the 

 Kibeira de S'^ Luzia, during July 1855. It is a truly indigenous 

 Ftirficit/a, and of a very remarkable type,^ — its apterous body, much 

 abbreviated (apically-enuuginate) elytra, and sub-opake, greatly 

 tlattened surface, in conjunction with the total freedom of even 

 its 7nale forceps from internal teeth, giving it a character which 

 it is impossible to mistake.

Inhabits Madeira proper, occurring principally beneath the 

 loose outer tibre of the gigantic Heath-trees, on the upper limits 

 of the sylvan districts, — from about 4500 to 5000 feet above the 

 sea. It has been examined by Dr. Fischer of Friburg, who 

 regards it as new, though allied to the B. marginata of Southern 

 Europe.
