this as probable. Indeed practically it would be most rash to act 

 upon the latter hypothesis ; for the topographical evidence would 

 rather tend perhaps to uphold their specific distinctness, seeing that 

 the Canarian insect occurs unchanged in no less than five separate 

 islands of the archipelago, and the Madeiran one in two each of 

 them retaining its peculiar features unaltered by surrounding in- 

 fluences and the most opposite local conditions. 



The B. subcallosum is universal in all the islands of the Canarian 

 Group except the two eastern ones, Lanzarote and Fuerteventura 

 (in which it has not yet been observed), abounding at the edges of 

 the streams, and in damp places generally, at most elevations.

Occurs (though somewhat rarely) at the edges of the streams, and 

 about wet rocks, in Madeira proper and Porto Santo. It is closely 

 allied to the European B. callosum, and about equally so to the sub- 

 callosum of the Canaries ; nevertheless, as already stated, I believe 

 the three forms to be specifically distinct.
