J. HOPKINSON—SCALE-INSECTS. 
enemies of the Coccidae which they may have to rely upon to keep 
down their number. 
I have to-day received from the author several specimens to 
exhibit, and also mounted specimens of one species ( Lecanium 
bituberculatum on Cratcegus oxyacantha from King’s Langley) for 
the Herts County Museum. The other species are Parlatoria 
pergandii on orange and lemon, P. zizyphi on lemon, Mytilaspis 
pomorum on apple, Apterococcus fraxini on ash, and Cryptococcus 
fagi on beech. On one orange there is a quantity of soot-fungus 
set up by honey-dew secreted by the coccid Dactylopius citri. In 
an accompanying letter Mr. Kewstead says that he would be 
delighted to name any coccids which our members may send to 
him at any time, and would also willingly mount them for the 
Museum. The specimens should be addressed to him at the 
Grosvenor Museum, Chester. 
P.S.—Since this paper was read I have been informed by 
Mr. Kewstead that he has received from the Editor of the ‘ Gardener’s 
Chronicle ’ specimens of Lichtensia viburni (female) which were 
found at Poles Park, Ware, on 10th July, 1903, on ivy “ growing 
on poles in the open.”
