428. Corticaria rotundicollis. 



Corticaria rotundicollis, WolL, Ins. Mad. 186 (1854). 

 1 M, Cat. Mad. Col 65 (1857). 



Habitat Maderenses (Mad.), in sylvaticis editioribus parce occurrens. 



Observed hitherto only in Madeira proper, where it occurs spa- 

 ringly within the sylvan districts of intermediate and rather lofty 

 elevations. 



429. Corticaria angulata. 



Corticaria angulata, WolL, Cat. Can. Col. 148 (1864). 

 Habitat Canarienses (Lanz., Fuert., Can.), hinc inde hand infreqnens. 



A Canarian species which I have detected hitherto only in Lan- 

 zarote, Fuerteventura, and Grand Canary, where, however, it is 

 locally far from uncommon. 



430. Corticaria curta. 



Corticaria truncatella ? (Mots.), Mann., in Germ. Zeitsch. v. 59 (1844). 



ciirta, WolL, Ins. Mad. 187 (1854). 



, Id. Cat. Mad, Col 65 (1857). 



, Id., Cat. Can. Col 149 (1864). 



Habitat Maderenses (in CMo sola non observata) et Canarienses (in 

 Hierro sola hand detecta), late sed vix copiose diffusa. 



Although nowhere very abundant, this seems to be the universal 

 Corticaria of these islands in the whole of which I have no doubt 

 that it will be found to occur. Already indeed it has been observed 

 in every one of the Madeiran islands except the Flat Deserta (or Ilheo 

 Chao), and in all the Canarian ones except Hierro ; so that we may 

 feel pretty sure that it is quite universal. 



It is a European species, and has lately been captured in England 

 by Mr. Brewer who considered it to be the truncatella, Mann. If 

 this should prove to be correct, of course the name of curta will have 

 to be suppressed ; but as I am informed by Mr. Rye that the British 

 examples do not by any means accord with Mannerheim's diagnosis, 

 I cannot alter the title under which I described the Atlantic insect 

 until this question has been properly decided. 



431. Corticaria tenella. 



Corticaria tenella, Woll, Cat. Can. Col 150 (1864). 

 Habitat Canarienses (Can., Ten., Grow., Palma, Hierro), passim.
