Reports to various Correspondents. 29 
Another species, 0. leguminicola, feeds in the flower heads and 
also lives at the roots during the winter. 
The adult fly of Cecidomyia trifolii is a small brown midge with 
a reddish brown abdomen ringed with black, the two wings are 
yellow at the base and covered with brown hairs and are somewhat 
iridescent. 
Little is definitely known concerning this pest. 
There is no remedy, but a good dressing of artificial manure often 
carries the plant over the damage. As such pests may continue 
from year to year, I should feed off the clover and plough deeply 
with a skim coulter, so as to bury the larvae and pupae in the soil, 
so that when the flies hatch out they cannot come above ground. 
Of course this is only advised if the crop is severely damaged. Such 
pests when once they become plentiful may cause endless harm 
unless drastic measures are taken against them. 
Some doubt has been expressed by Miss Ormerod of these red 
maggots doing damage, but I cannot agree on that point, as I have 
seen acres of clover ruined by them. There were no other insects 
present, no sign of eelworm, and not enough fungi to account for the 
harm done in any of the specimens sent this year. 
ANIMALS INJURIOUS TO FRUIT AND FRUIT TREES. 
Big-bud Mite in Black Currants. 
A number of enquiries have been received concerning the Big 
Bud Mite. Diseased plants have been sent from various parts of 
Kent, from Harpenden, and from Guildford. 
Doubts have been expressed that any clean black currant stock 
can be obtained. As far as Kent is concerned there is very little, 
but in other districts a few enquiries soon revealed that such con- 
ditions do not appear everywhere. Mr. Wm. Bear, of Magham 
Down, Hailsham, writes that his Lee’s Prolific are quite clean ; some 
infested Baldwins he obtained were eventually destroyed and the 
disease reduced to a minimum. This stock of Lee’s Prolific came 
from Preston. I applied to the grower and his answer was that he 
had stock of Lee’s Prolific and Carter’s Champion quite clean. 
These two kinds he had grown for years and had kept free from 
mites ; but Black Baldwins he had given up growing, having found 
two or three bushes, purchased three or four years ago, with a few
