and Fuerteventura, the two eastern islands of the Canarian Group, 

 where it was taken both by Mr. Gray and myself. It is found 

 under stones at intermediate elevations, making its appearance after 

 the winter-rains.

A single specimen of this Canarian insect is all that I have yet 

 seen. It was captured by Dr. Crotch " in Teneriffe," during the 

 spring of 1862.

Habitat Canarienses (Lanz., Fuert., Can., Ten. ?), sub lapidibus hinc

An insect widely spread over Mediterranean latitudes, assuming 

 several slight (and very unimportant) local modifications which have 

 been described as species. It occurs abundantly in the eastern part 

 of the Canarian Group, but seems gradually to disappear as we ap- 

 proach even the central islands. Thus in Lanzarote and Fuerte- 

 ventura it is exceedingly common, and moreover quite universal; 

 whilst in Grand Canary it appears to be confined to a few sandy 

 places along the coast. Whether it exists at all in Teneriffe I have 

 not been able completely to satisfy myself ; but I think perhaps that 

 it may just make its appearance in one or two spots. At any rate 

 I have received examples professing to be Teneriffan both from the 

 Baron Paiva and M. Hartung ; but as I have never met with it in 

 that island, and since I have so often found the material transmitted 

 to me from those two sources to be remarkable for its inaccuracy, I 

 cannot but feel that the Teneriffan habitat of the species requires at 

 least further corroboration.
