Feornined from Trinidad. Mr. T. D. A. Cockerell has also found a 
specimen of it in Barbados cane ; and writes (25) :— 
Thus it appears that the sugar-cane pest now causing injury in 
Barbados is not the Xyleborus, and not even the P adem but the 
Sphenophorus, or weevil. This is, of course, so far as one can tell from 
_ the specimens r received ; but it is likely siti that the iiw moth also 
in Barbados, and is reponsible for a part of the damage. It is 
Minden that the vend follows the depredations of the weevil 
~ This s statement, hoas very likely true, is P rather positive, 
considering the small am jount of material he appears to bave examined. 
My jim from Tegar showed previous ie vot the Sphenophorus, 
but in the face o er evidence from the island I cannot possibly say 
on ‘the testa “of zi " canes, that dia insect is the necessary 
sed the Sphenophorus)." 
«Fr rom these opinions, however, the Committee are compelled, by the 
x cet of their observations, to differ, at any rate so far as Trinidad is 
cerned. In the course of their researches the committee have found
