TOMICID^E. 237 



Tomicus villosus, Woll, Ins. Mad.-2W (1854). 

 , Id., Cat. Mad. Col. 96 (1857). 



Habitat Maderenses (Mad.}, sub cortice laxo emortuo praesertim in 

 castanetis parce occurrens. 



The European T. villosus occurs sparingly in Madeira proper, 

 principally beneath the bark of Spanish chestnut- trees within the 

 cultivated districts. Possibly it may have been naturalized, acci- 

 dentally, from higher latitudes. 



668. Tomicus Saxeseni. 



Bostrichus Saxesenii, Ratz., die Forst- Insect, i. 167 (1837). 

 Tomicus Dohrnii, Woll, Ins. Mad. 290 (1854). 



, Id., Cat. Mad. Col. 96 (1857). 



Saxesenii, Id., Cat. Can. Col. 255 (1864). 



Habitat Maderenses (Mad.} et Canarienses (Ten., Gom., Palma), 

 vel in lauretis vel in pinetis degens. 



Likewise a European insect, and one which is very widely spread 

 over these Atlantic islands where it has adapted itself to various 

 kinds of trees. Of the Madeiran Group I have observed it only in 

 Madeira proper, where however it abounds at lofty elevations within 

 the sylvan districts attacking, almost exclusively, the native 

 laurels. At the Canaries, on the other hand, it is comparatively 

 scarce, and seems to prefer pine trees. At any rate the few exam- 

 ples which I have myself met with were taken from under the bark 

 of the Pinus canariensis in Teneriffe and Palma in the former of 

 which islands it was also found by the Messrs. Crotch, in the Final 

 above Ycod el Alto. I have likewise examined a series which was 

 obtained by the Messrs. Crotch in Gomera according to a note now 

 before me, " out of poles," though whether the poles were of fir 

 or laurel I am unable to say. 



669. Tomicus perforans. 



Bostrichus ferrugineus?, Fab., Syst. Eleu. ii. 388 (1801). 

 Tomicus perforans, Woll, Cat. Can. Col. 96 (1857). 



Habitat Maderenses (Mad.), obturamenta doliorum in cellis vinariis 

 Funchalensibus destruens ; forsan ex alienis introductus. 



Although, from information which I have received, there can be 

 little doubt that this Tomicus is occasionally very destructive in the 

 wine-cellars of Madeira proper (where it feeds on the corks used as 

 bungs for the casks), nevertheless it is somewhat remarkable that I 

 have been unable to obtain hitherto more than a single example of
