naturalized from more northern latitudes. I have taken it sparingly, 

 in and about houses, in Lanzarote and TenerifFe.

The C. maculosa, which I described fully in my Paper on ' Ma- 

 deiran Additions ' cited above, may be said without hesitation to be 

 universal throughout the archipelago ; for although I do not happen 

 to have met with it hitherto in Grand Canary, there cannot be any 

 doubt that it must exist there, no less than in the remaining six 

 islands of the Group, — in all of which I have captured it, more or less 

 abundantly. It occurs in various situations, but is more common, I 

 think, beneath the dry outer fibre of the dead Euphorbias than else- 

 where. In such positions I have observed it frequently at Haria, in 

 the north of Lanzarote ; as also on the mountains above S'" Cruz of 

 TenerifFe, and even on the little isle of Lobos, off the extreme north 

 of Fuerteventui-a. In Fuerteventura itself, however, I brushed it, 

 in considerable numbers, on the 28th of January 1858, from off an 

 old bush of the common Rosemary {Rosmarinus officinalis, L.), at 

 Agua Bueyes ; and I have taken it out of the crevices of wood (used 

 for a gate) in the Barranco above San Sebastian, of Gomera. It 

 would seem likewise to be independent of elevation ; for in TenerifFe 

 I have found it from almost the sea-level (at 8*=* Cruz and Puerto 

 Orotava) to the slopes above Taganana, the Agua Mansa, and even 

 to the lofty Cumbre adjoining the Cauadas, — at an altitude of more 

 than 8000 feet*. In TenerifFe and Gomera it was met with also by 

 Dr. Crotch. 



The pale hue and dark (though often very obscure, and generally 

 interrupted) postmedial fascia of this Corticaria will at once readily 

 distinguish it. Examples, however, in which the elytral patch is quite 

 obsolete (and such are by no means uncommon, particularly where 

 the insect is immature) might almost be conio\m([e(\., prima facie, with 

 those of the C. fulva ; nevertheless they may always be known from 

 the latter by their pubescence being shorter and less coarse, by their 

 prothoracic fovea being somewhat shallower, by their elytra bein"- 



* The single example which I detected at this great elevation has its pubescence 

 a trifle longer and coarser than is tlie case in the ordinary ones ; but I can see 

 nothing about it to warrant the suspicion that it is specifically distinct.
