I also received specimens of the Spotted Snake Millepede from 
near Bradford as a pest very destructive to vegetation. In this case 
specimens of the present and last season were sent.

Glenny further notes :—“ But the greatest loss has been from White 
Lice. They have descended in myriads upon Turnips, Savoys, and 
Cabbages. Some crops of the former have been annihilated, more 
particularly the autumn-sown pieces. No description of the Cabbage 
tribe has escaped. The produce now reaching the metropolitan 
markets from our district is damaged and reduced in value by these 
disgusting pests on the exterior covering. 
“ The leaves of the plant curl over the intruders in such a way that 
wind and rain hardly interfere with their devastating progress, and 
when the heart of the young and tender esculent is reached its doom 
is fixed, and the crop is settled.” 
The Cabbage Aphides probably take the name of “ White Lice” 
from the light colour of the young when first produced, and, like Hop 
Aphis, how to get rid of them on a large scale of cultivation needs yet 
to be made out. 
Something may be done in garden growing by cutting off the 
leaves which are infested as soon as ever patches of Lice are seen 
beneath them. The attack would then be prevented from spreading ; 
and likewise, in garden cultivation, a good drenching of soft-soap with
