CURCULIONID^:. 281 



A more critical examination of the type on which, the A. cylindri- 

 collis of my ' Ins. Mad.' was founded, has satisfied me that it is only 

 a largely developed specimen of the A. Wollastoni.

Acalles seticollis, Woll, Cat. Can. Col. 291 (1864). 

 Habitat Canarienses (Ten., Hierro), in herbidis intermediis rarissimus. 



The representative at the Canaries of the Madeiran A. Wollastoni, 

 and found in much the same land of places. It has been taken 

 (very sparingly) by myself in Hierro, and by the Messrs. Crotch in 

 Teneriffe. It bears so strong a primd facie resemblance to the 

 A. Wollastoni that it is difficult to believe that it can be more than 

 a geographical modification of that insect ; and yet, when carefully 

 inspected, it will be seen to have a few very constant characters of 

 its own. Thus, it is altogether more setose than its Madeiran ally, 

 and its prothorax when denuded of its scales is much more coarsely 

 and densely punctured, whilst its elytra have the punctures of their 

 striae less developed and their interstices more rugulose. 



778. Acalles globulipennis. 



Acalles globulipennis, WolL, Ins. Mad. 339 (1854). 

 1 Id., Cat. Mad. Col. 110 (1857). 



Habitat Maderenses (Mad.), praecipue sub cortice laxo necnon inter 

 lichenes ad truncos arborum vetustos crescentes in lauretis 

 humidis editioribus occurrens. 



This comparatively rounded little species, which is more on the 

 pattern of the ordinary Acalles of more northern latitudes, is widely 

 diffused over the damp sylvan districts of Madeira proper where it 

 occurs principally beneath the loosened bark, and amongst lichen 

 growing upon the trunks, of the old laurels. 



779. Acalles pilula. 

 Acalles pilula, WoU. t Cat. Can. Col. 292 (1864). 



Habitat Canarienses (Ten., Gom., Palma, Hierro), in locis similibus 

 ac praecedens et forsan ejus varietas geographica. 



Whether this Acalles be anything more than a Canarian modifica- 

 tion of the last one, I will not undertake to decide ; but it certainly 

 bears as great a resemblance to it, at first sight, as the A. seticollis 

 does to the Madeiran A. Wollastoni. Yet (as in the case of that
