CERAMBICID^E. 



the latter circumstances I have taken it abundantly in Porto Santo 

 and on the two northern Desertas, of the Madeiran archipelago ; 

 whilst Palma (where, however, we may he quite sure that it exists) is 

 the only one of the seven Canarian islands in which it does not happen 

 to have been captured. Its detection in Gomera is due to the recent 

 researches of the Messrs. Crotch. 



In my last published Catalogue I regarded the Canarian ex- 

 amples of this Bruchus as specifically distinct from the Madeiran 

 ones ; but a careful inspection of fresh material has since convinced 

 me that the very small differential characters on which my diagnosis 

 was made to depend are quite insufficient to indicate more than a 

 most trifling geographical phasis of the insect some of them indeed 

 being perhaps sexual, rather than specific. But most of the Bruclii 

 are so eminently variable, both in size and general development, 

 that the only thing to be surprised at is that there should not be a 

 greater amount of discrepancy than is really the case between the 

 representatives of the B. lichenicola in the two Groups.

This singularly long-horned Bruchus appears to be confined (so 

 far as I have observed hitherto) to the higher altitudes of the Cana- 

 rian Group, where it occurs sparingly in the regions occupied by the 

 Pinals ; though whether it is positively attached to the fir trees I 

 have not sufficient evidence to decide. At any rate, I have taken it 

 in Grand Canary, Teneriffe, and Palma, in every instance, either 

 amongst or near the Pinus canariensis.
