16 BEET CARRION BEETLE. 
Dates of attack in the notes before me range during the earlier part 
of June up to about June 19th, when many of the grubs were nearly 
full grown. When full-fed, they go down into the ground to a depth 
of about three to four inches to change to chrysalis state, from which 
the beetles appear in about three weeks. The beetles are to be found 
in winter or spring under stones, clods, or in moss or rotten wood, 
and ‘‘ are common in April in dead animals.” 
This last item seems to me to be very possibly an important point 
to notice relatively to the carrion-infesting part of their habits. The 
attack has been found both where bone manure has been used and 
where it has not been used, so this gives us no clue; but the fact 
mentioned by Mr. F. N. Budd (p. 15), of the infestation having ap- 
peared where farm manure was carried from Batworthy, points to a 
method of transmission which the attraction of garbage, putrid animal 
matter, and the like, would make very likely. 
The suggestion of Mr. Sym Scott, in the observations previously 
referred to, that he purposed knocking ‘about the Mangolds a few 
wild pigeons, rooks, hawks, or similar vermin, which we generally 
shoot in spring, and trying what effect’’ this would have, is worth 
consideration. In many insect attacks ‘‘ trapping,” that is, attracting 
the insects to some food, which can with no more than reasonable 
trouble be presently destroyed with the contained pests, answers well, 
at small cost; but we much need further information as to how to 
‘‘ stamp out” the infestation, and as the kinds of crops or weeds liable 
to suffer under attack are gradually found to be more numerous than 
we were aware of, I have this year placed the above short observation 
under the double name of the insect rather than under any one of the 
crops which it injures or ravages to complete destruction.
