TENEBRIONID^S. 



Deserta (or Ilheo Chao), in the Madeiran Group from beneat 

 slabs, or blocks, of stone in the centre of that peculiar little island. 

 I am doubtful whether the genus is sufficiently distinct from Ccelo- 

 metopus, of Solier, found in Spain and Portugal, but of which I 

 possess no type for comparison.

I have not myself observed this common European insect in any 

 of these islands, though its near ally the T. obscurus is almost uni- 

 versal throughout the whole of them. But of the molitor the only 

 two Atlantic specimens which I have yet seen are from the small 

 collection of the late Dr. Heineken by whom they were captured,

 introduction, through the medium of commerce, from more northern 

 latitudes.

There can be little doubt that this Tenebrio, which is the scarcer 

 of the two species in central Europe, is universal throughout the 

 whole of these islands which are inhabited it having become per- 

 manently established, through the medium of commerce. In Madeira 

 proper it is locally abundant, and it has been obtained by the Barao 

 do Castello de Paiva from Porto Santo j whilst at the Canaries it has
