Habitat Maderenses (Mad.), in sylvaticis humidis editioribus lignum

Peculiar (so far as observed hitherto) to Madeira proper, where i 

 occurs sparingly beneath the bark of trees and in rotten wood at in- 

 termediate and lofty elevations.

Occurs in ants' nests (particularly those of (Ecophtliora pusllla, 

 Heer), in warm, sunny spots in the south of Madeira proper where 

 it is occasionally far from uncommon. And I have also captured it 

 (though much more sparingly), in similar situations, in Teneriffe and 

 Gomera of the Canarian Group. It is an insect of very difficult lo- 

 cation in a natural system of arrangement, and is merely placed here 

 on account of its according better in some of its structural peculiarities 

 with the Colydiadce (though far removed from them in other respects) 

 than perhaps with any Coleopterous family hitherto enunciated.
