120 TURNIP. 
But at present we do not, I believe, know the exact appearance of 
the Strawberry beetle larve, or of the pup, nor where they lie, nor 
how long they take for their changes, and we are greatly needing 
more information to check the increasing prevalence of this destructive 
pest. 
TURNIP: 
Diamond-back Moth. Plutella cruciferarum, Zeller. 
PLUTELLA CRUCIFERARUM.—1, caterpillar; 2, eggs; 3, Diamond-back Moth (all 
natural size); 4, 5, Diamond-back Moth, at rest and flying (magnified). 
During the past year there has been once again some amount of 
mischief from infestation of caterpillars of the Diamond-back Moth on 
leafage of Turnips and Swedes; but this has been nothing to compare 
in magnitude with the attacks of 1891 and 1892, nor so widely preva- 
lent as that of 1894, which, though not of any great importance, was

the South of England to as far north as St. Andrew’s and Anstruther, 
Co. Fife, N.B., and to the neighbourhood of Aberdeen. 
But, as was the case with previous attacks, such small amount as 
there was last year was mostly on land in the neighbourhood of the 
sea-coast. The district of Ballachulish is on Loch Leven and Loch 
Linnhe (an inlet of the sea), in the West of Scotland; Seafield and 
Aberdeenshire generally, in which county the Diamond-backs did a 
good deal of injury to the Turnip crop, is nowhere far from the sea; 
and Arbroath (Co. Fife) is on the sea-coast in the East of Scotland. 
The only English observation sent was from near Scarborough on the 
sea-coast in Yorkshire. 
The first communication was sent me on July 14th by Mr. W. W. 
Anderson, from Ardsheil, Ballachulish, Argyleshire, N.B.:— 
‘‘ The enclosed is, I believe, a Diamond-back caterpillar. I found
