tional; and it seems far from unlikely therefore that the wreck 

 of an American vessel upon those dangerous rocks may have been 

 the occasion of timbers being cast on shore which were infested by a 

 wood-borer so eminently likely to attack recently-sawn planks. At 

 least some such solution as this, of a problem otherwise difficult, ap- 

 pears to me to be by no means impossible.

The European G. pygmcea is widely spread over these Atlantic 

 Groups, where in all probability it has become established from 

 higher latitudes. It occurs for the most part about houses, or in 

 their immediate neighbourhood, and seems to be attached principally 

 to different kinds of wicker- or basket-work on the dry sticks, and 

 wood, of which it feeds. It has been found sparingly, around 

 Punchal, in Madeira proper, and, more commonly, in Fuerteven- 

 tura, Gomera, and Palma, of the Canaries. During my sojourn in 

 the last-mentioned island, I took it (at the Souces) emerging from 

 its perforations in the sides of some light open trays in which silk- 

 worms were being fed.

This fine Longicorn has been detected hitherto only on the extreme 

 summits of the two southern Desertas, in the Madeiran Group, where 

 it is truly indigenous and of excessive rarity. I have taken it in
