lofty Cumbre adjoining the Canadas, had its elytra as pale as the 

 Gomeran ones. And it is possible therefore, unless indeed that 

 particular individual happened to be immature (and, so, unnaturally 

 pale), that the specimens from the very elevated regions of Teneriffe 

 may perhaps resemble the Gomeran ones in hue, and that merely 

 those from the Pinal have their elytra more or less darkened.

Occurs sparingly in the sylvan districts of Madeira proper, at in- 

 termediate and rather lofty elevations, where it is found beneath 

 logs of wood and under the moist putrid bark of trees. The cha- 

 racters which separate it from the M. pronus, of which I formerly 

 regarded it as a mere depauperated state, have been fully alluded to 

 in the Appendix.

Habitat Maderenses (Mad.), in locis similibus ac prsecedens. 



The European M. pronus (for I cannot detect any real difference 

 between the Madeiran examples and those from more northern 

 countries) is found in exactly the same kind of places as the last 

 species, within the wooded districts of Madeira proper. It appears 

 to be exceedingly rare, and has not yet been observed in any of the 

 other islands. 



1330. Mycetoporus rufus. 



Mycetoporus rufus, Woll., Cat. Can. Col. 558 (1864). 



Habitat Canarienses (Ten., 6rom.), in inferioribus iutermediisque 

 rarior. 



This large and beautiful Mycetoporus has been captured hitherto 

 only in Teneriffe and Gomera, of the Canarian Group, where it 

 occurs very sparingly at low and intermediate altitudes.
