5052 THE ZooLocist—Aveust, 1876, 
Evhibitions, dc. 
Mr. Douglas exhibited the following Psyllidw, taken by himself near 
Lee, Kent, viz. :— 
Psylla ? On birch trees. . Possibly P. Betule, Linn., Flor. 
», spartifoliella, Férst. On broom bushes. 
Aphalara renosa, First. New to the British Fauna; now first identified 
as living on Achillea millefolium. 
Rhinocola aceris, Linn, On maple trees (Acer campestris). 
a erice, Curtis. On heather. 
The President showed some microscopic slides containing specimens of ~ 
Diptera, &c., prepared with extraordinary care by Mr. Enock. He also 
brought for exhibition twigs of horse-chestnut from Oxford, that had been 
attacked by some kind of larva, which had eaten away the inside of portions 
of the stem, causing the buds to drop off. He was in doubt whether the 
insect was Zeuzera Alsculi, or some other, but he would be glad to know if 
the destruction to the trees had been noticed elsewhere. He also exhibited 
two species of Coccus, one of them on Camellia leaves in his greenhouse, 
which he had previously described in the ‘ Gardener's Chronicle,’ under the 
name of C. Camellie, and which had afterwards been observed by Dr. Ver- 
loren in his greenhouse in Holland. The female, which is one line in 
length, discharges a white waxy matter, having the appearance of the 
excrement of a young bird. The other species had been sent to him by the 
Rev. T. A. Preston, of Marlborough, on a species of Euphorbia, obtained 
from Dr. Hooker, of Kew. The leaves were covered with small scales, 
which, on close examination, were observed to have two small spines 
attached, and these proved to be the caudal extremities of the males. 
These insects emerge from the pupa backwards, and in consequence they 
make their appearance with the wings drawn forwards over the head. 
Mr. Stevens exhibited varieties of some British Geometre, and what 
appeared to be a small variety of Lyceena Adonis, taken near Croydon.
