colour and size, cannot be easily overlooked. The 
havoe they make in the Parisian Rose gardens is 
fearful, compared with what we experience in 
Britain. Le Vere Blanc, as they are there called, 
is the greatest enemy the French Rose-growers have 
to contend with. Their habits in many respects 
resemble those of the Cockchafer. We know of no 
means more likely to reduce the numbers of these 
Rose-chafers than by capturing them in their beetle 
state, which, from their large size and conspicuous 
colours, is no difficult matter. 
The Antler Rose Sawfly (Cladius  difformis 
panza).—Several species of Cladius attack the 
Rose in their larva state, devouring not only the 
foliage, but often the pith also. Their attacks on 
the foliage are first observed in the shape of 
innumerable small perforations, which daily in- 
crease, portions of the margins being also devoured. 
The cause of this is only discovered by turning up 
the under-side of the leaf. In size they scarcely 
exceed half an inch, nearly cylindrical, tapering a 
little towards the tail. Their colour is bright green, 
covered with short, erect hairs, with a darkish line 
down the back, and one much darker on each side. 
The head is brownish and horny, with two small 
black dots on the sides. It is difficult to point out 
any remedy, except what has been so often recom- 
mended for caterpillars in general, viz., dusting the 
plants with powdered hellebore, or with snuff, 
watering with lime or soot water, shaking the 
branches suddenly and catching the enemy on a 
cloth spread below.
