CANARIAN COLEOPTERA. 



porting to have been taken at the Agua Garcia, has been communi- 

 cated by the Barao do Castello de Paiva. 



The Canarian examples have the tubercles on either side of their 

 prothorax a trifle more developed than is the case in specimens which 

 I have examined from the south of Europe, and the posterior edge of 

 their pronotum is somewhat less thickened and more sinuated ; but 

 I can detect no diff'erence about them of sufficient importance to war- 

 rant the suspicion that they are specifically distinct. 



591. Criocephalus pinetorum. 



Criocephalus pinetorum, JVoU., Journ. of Ent. ii. 103 (18G3). 



Habitat Palmam, in trunco vetusto Pini canariensis, in pineto 

 quodam antique elevato crescentis, Junio ineunte a.d. 1858 repertus. 



The example from which this Criocephalus was described was cap- 

 tured by myself, in the pupa state, from the dead stump of a Finns 

 canariensis, in the old Pinal of the island of Palma between the 

 plains of Los Llanos (of the Banda) and the great Caldeira. Un- 

 fortunately it is scarcely mature ; but I beheve that it is truly the 

 exponent of a separate species, and cannot be regarded as a depau- 

 perated individual of the C. rusticus. Nevertheless, until further 

 specimens have been obtained, I can hardly consider that its differ- 

 ential characters have been satisfactorily defined. 



Assuming, however, the example above alluded to to be typical, I 

 may add that the C. pmetorum would appear to be smaller and paler 

 than the rusticus — being of a reddish-brown, with the Umbs bright 

 rufo-ferruginous; its forehead is more triangularly-impressed between 

 the eyes, but less deeply foveolated in the centre ; its prothorax, on 

 which the lateral tubercles are fewer, has its anterior and posterior 

 margins straighter (or less sinuated) ; and its elytra are rather more 

 abbreviated behind, and have their longitiulinal costaj less evident. 



"Whether distinct or not from the C. rusticus, the present Criocephalus 

 is decidedly common in the Pinal of Palma already referred to (and 

 perhaps, therefore, throughout the Pinals generally) ; but as my visit 

 there happened to be at the wrong season of the year for the perfect 

 insect, I could only obtain larvae and pupae — both of which, however, 

 were abundant in the decaying trimks of the pine-trees.
