CARABID^l. 15 



Occurs in the damp sylvan regions of Madeira proper, where it is 

 extremely scarce and ascends to a rather high altitude.

Found sparingly in Teneriffe by the Messrs. Crotch, during their 

 late Canarian campaign, I believe, under leaves and refuse, at 

 Ycod el Alto.

Inhabits the sylvan regions of a rather high elevation in Teneriffe, 

 where it occurs sparingly beneath the loosened bark of the laurels in 

 damp spots.

Found both in the Madeiran and Canarian Groups, though perhaps 

 (on the average) at a rather lower elevation than the D. sigma, and 

 more frequently (though by no means always) within the sylvan 

 districts than elsewhere. I believe it to be truly distinct from the 

 sigma, and I may add that it was so regarded by Schaum ; never- 

 theless occasional specimens approach the latter very closely. It is 

 apparently as inconstant as that insect, both in the exact shape and 

 colour of its prothorax and in the depth of its fascia. Nevertheless 

 the latter is nearly always more developed than is the case in the 

 sigma, its elytra are more elliptical (or rounded off at the shoulders) 

 and have their scutellary region generally a little infuscated, and its 

 surface is frequently subopake *. In the Teneriffan examples (which
