in these niattci-s of insect deterrence — might be used with ashes, or 

 possibly be wortli experimenting with dilute as a steep. 



I also suggested, besides, the manifest means of destroying all rubbish 

 containing or attracting Calandra, or larvae generally, that some pits of 

 water with a few putrid canes in tliem, such as are described as at once 

 biinging tliem on exposure, might serve as traps on a large scale, with only 

 the expense of a boy to watcli and destroy the weevils as they accumulated. 

 The beetles appear easy of attraction, and in the case of our English 

 Calandra, I have trapped them by myriads in this way. As some fear 

 was expressed by one of the managers that in destroymg the infested canes 

 they would do harm by also destroying the ants on the plant, I suggested 

 that probably this amount of loss would be quite immaterial, and that it 

 was of the greatest importance to destroy the borer larvae wherever 

 attainable; but it appears to me that destruction should be by burning, 

 not simply crushing, as — so far as I understand the operation — the eggs 

 and smaller larvae would be very likely to escape. 



Other points have, of course, been entered on ; but, as far as I am able, 

 1 have endeavoured to give those that appear of most importance, and any 

 suggestions that may be kindly offered will be most gratefully received.

Exhibitions, dc. 



Mr. Philip B. Mason exhibited specimens of Harpalus ohlongiuscuhis, 

 Dej., taken in August, 1879, at Portland. One specimen had been 

 captured there last year by Mr. Harris; but at least a score had now been 

 taken in this locality, thus confirming the claim of this species to a place 

 in the British list. Mr. Mason also exhibited, on behalf of Mr. Gameys, 

 of Repton, specimens oi Euplectus ambiguus, Reich., showing the difference 

 between thir; and the var. " duplo minor'" described by Thomson. The 

 variety exhibited, which has not been before recorded in Great Britain, was 

 taken at Repton in flood refuse during the late spring.
