TOMICID.E. 



indeed often in company with it. It abounds in the damp laurel- 

 woods of Madeira proper, at intermediate and lofty altitudes ; and I 

 have taken it in similar situations in Teneriffe and Falma, of the 

 Canarian Group, where however it is comparatively scarce. It was 

 also found by the Messrs. Crotch, during the summer of 1864, in 

 Gomera. 



Fam. 50. TOMICIIXflE. 



Genus 211. TOMICUS. 

 Latreille, Hist. Nat. des Ins. iii. 203 (1802). 



665. Tomicus nobilis. 



Tomicus nobilis, Woll, Ann. Nat. Hist. ix. 441 (1862). 

 1 Id., Cat. Can. Col. 254 (1864). 



Habitat Canarienses (Ten., Palma, Hierro), lignum antiquum in 

 pinetis editioribus destruens. 



Apparently peculiar to the Finals of the Canarian Group, where 

 it perforates the old trunks of the Pinus canariensis. I have taken 

 it in Teneriffe and Palma ; and it was captured by the Messrs. 

 Crotch in the remote, but elevated, Final in the south of Hierro. 



666. Tomicus erosus. 

 Tomicus erosus, WolL, Cat. Mad. Col. 95 (1857). 



Habitat Maderenses (Mad.), sub cortice in castanetis praecipue 

 degens. 



Closely allied to the Canarian T. nobilis, of which indeed it may 

 be regarded as the Madeiran representative. Hitherto it has been 

 found only in Madeira proper, where it occurs sparingly beneath the 

 bark of trees (principally, I believe, of the Spanish chestnut) on the 

 mountains above Funchal*. 



667. Tomicus villosus. 



Bostrichus villosus, Fab., Ent. Syst. i. ii. 367 (1792). 

 Tomicus villosus, Steph., III. Brit. Mit. iii. 356 (1830). 



* It is very possible that I may have overlooked characters which would addi- 

 tionally tend to separate the two species; but it seems to me that the T. erosus 

 differs from the Canarian T. nobilis, merely, in its uniformly smaller size and 

 narrower outline, in the punctures on the hinder region of its prothorax and elytral 

 interstices being a little smaller, and in the asperities which fringe the obliquely 

 truncated portion of its elytra being altogether less developed. Yet although so 

 nearly allied, I am quite satisfied that they are truly and specifically distinct.
