attracted it, and so the beetles would be found at the fruit quite 
independently of what manure might have been used for the special 
Strawberry-ground. 
Of the two kinds of I’terostichi, having only abortive wings, there 
would be hope of clearing the ground, or at least of their not spreading 
unless carried in soil. These (that is, the P. vulgaris) were beginning 
to pair on the 29th of July (the pairing of the H. rusicornis had occurred 
at least nine days earlier), therefore egg-laying might shortly be ex- 
pected; but though clusters of eggs were reported as seen, it seems 
open to doubt whether these could be of the Ground Beetles, which 
would be so small as to be difficult of observation. But later on the 
grubs would be hatching, which, like those of the Ground Beetles 
generally, might be expected to be long, parallel-sided, fleshy, and 
somewhat flat above; the head and first segment hard; the six legs 
horny; and the tail extremity with two horny or fleshy appendages, 
somewhat like fleshy bristles, on the upper surface, and beneath to be 
furnished with a caudal foot. 
Whilst these grubs are young and tender some dressing might kall 
them, but the only application which it appears to me would be likely 
to do this without injuring the Strawberry-plants would be Paris- 
green, used either in dry or fluid mixtures. A very careful series of 
experiments have shown that this was not absorbed into the plants 
experimented on; and there might, I think, be such good hope of 
it poisoning the young grubs, that it may be worth the trouble of 
trial. 
The only other preventives and remedies appear those of trapping 
mentioned at p. 85.
