This is the largest of the three Xyloperihce here enumerated ; it 

 is also more brightly coloured (its dark and pale parts, at any rate 

 on the elytra, being more rigidly defined), and likewise less clothed 

 with a decumbent yellowish pubescence, its central region, namely 

 the hinder half of the prothorax (which is even still more minutely 

 punctulated) and the anterior half of the elytra, being glabrous. 

 But, apart from these and other distinctions, the X. ficicola may 

 readily be known from its Atlantic allies by the retuse apical portion 

 of its elytra, which is much more abrupt and obliquely flattened 

 (and therefore better defined), having its lateral rim gradually raised 

 to within a short distance of the apex (which is itself acuminated, 

 divaricate, and recurved), and there suddenly terminated. 



The discovery of the X.ficicola is due to the researches of the 

 Messrs. Crotch, who detected it in Gomera, during their late expe- 

 dition to the Canaries, where I am informed by Mr. G. R. Crotch 

 that a considerable series of it, which are now before me, were bred 

 by them from the decayed wood of an old fig-tree.

X. prsecedenti similis, sed brevior, grossius pubescens (etiam in medio 

 parce sericeo-vestita) et colore omnino obscuriore (etiam partibus 

 pallidioribus magis suffusis infuscatis) ; vertice densius penicillato ; 

 prothorace postice paulo minus polito et ibidem densius ac multo 

 evidentius asperato-punctato (quasi fere granulate) ; elytroram 

 parte retusa multo minus abrupta minusque deplanata, in elytris 

 singulis nodulo parvo obscuro costiformi laterali ante medium 

 terminata (sed margine laterali haud elevato), apice vix producto, 

 vix bipartite, vix recurvo ; tarsis (saltern intermediis) etiam sub-
