'cane-borers' (in this case the Calandra pali)-iarnm) to the suffar-canes of 

 Demerara. 



" One piece shows the commencement of the attack, ' tlie preparatory 

 holes made for it to insert its eggs' (as stated in observations from tlie 

 colony); tlie second shows the complete destruction of the inside fibre of 

 the cane, and in the third piece the cane is completely hollowed out. 



" These specimens were accompanied by two living larvfe of the cane- 

 weevil, which formed their cocoons whilst on the way, and which it will be 

 noticed have availed themselves for the purpose, of the packing material ; 

 the inside of the cocoon which I have opened being, as usual, of fine cane- 

 fibres, but the outside consisting, in one case almost entirely and in the other 

 partially, of the straw or grass (still witli a few empty ears on it) in which 

 the cane was packed. The difference in material is rather interesting, as it 

 gives means of tracing the method of plaiting and arranging longitudinally 

 as well as merely twisting the fibres. The pupa was found to be dead 

 shortly after the specimens were placed in my hands, and is now shown 

 with the cocoon from wliich I removed it. 



" A single specimen of lepidopterous pupa vyas also sent over, lying in 

 the central gallery it had hollowed in a small cane-shoot little more than a 

 quarter of an inch in diameter. This pupa was singularly active when 

 I received it, moving at will for about an inch along its gallery; but 

 though placed in an evenly warm and moderately damp atmosphere, and 

 left undisturbed, excepting occasional examination for certainty that all was 

 iu order, I fear it is dead. 



" May I be permitted now to mention that after the last meeting 

 I communicated the results of the discussion on the borers to the Secretary 

 of the Colonial Company, who expressed his thanks for the attention that 

 had been kindly given to the sulject, as well as his hopes of further 

 valuable information from Mr. Distant and others of our Members. Such 

 suggestions as were then made he was about to forward to the colonj-, and 

 at the same time he stated he would direct specimens of the lepidopterous 

 borers in proper condition to be sent for examination. 



"I have since received' copies of reports from Mr. Im-Thurm, the 

 Curator of the British Guiana Museum, in George Town, giving some 

 information in addition to what was then sent. This consists chiefly of 

 further details of the working of the Froceras (or what are conjectured to be 

 Proceras) larvoe on piercing into the canes ; a short note of the quality of 

 the cane-tops cleared in cutting out grubs being sufficiently good for the 

 products to pay all expenses, which is a very material point in a remedy; 

 a sketch of the injury done by the various borers ; and also, what I wish 

 most particularly to call attention to, as it seems possibly to account for the 

 unusual amount of attack of all the species of borers at once. I gather 

 from a few words that the practice of burning off the remains of the standing
