June 1907.| NOTE ON OPHRYS HYBRIDA, POKORNY. 283 
I am indebted to my friend Mr. W. H. Hammond of 
Canterbury for the following notes made from the living 
plant when first found in this country and whose photograph 
has been reproduced in the “Orchid Review,” as cited above :— 
Sepals resembling O. muscifera, lateral ones rather broader 
at the base. Petals—the lower or labellum emarginate, lobed 
as in the fly, but broader. This petal altogether larger and 
broader than that of the fly. Markings as in the spider. 
Eyes smaller, not so conspicuous as in spider. Two upper 
petals like those of the spider, not serrated, and nearly the 
same width their whole length (not like antenne, as in the fly). 
No beak to anther, resembling the tly, cells and pollimia also 
resembling the fly. Rostellum, bracts, and ovary as in fly. 
Stigma as in spider. Habit of growth that of the fly, with a 
slender stem a foot or more in height. 
Dr. A. W. BortHwick exhibited a specimen of Nectria 
ditisssma in fine fruit; also <Aecidiwm strobilinwm trom 
Aberdeenshire. 
Dr. R. Stewart MacDouGati showed the tunnels and 
cells of the leaf-cutter bee (Megachile centuncularis). The 
female hollows out a burrow, and cuts oval pieces of leaf from 
rose (common) and from other plants, including forest trees. 
These oval pieces are fitted into a cell in which the bee 
places a store of food material, and then lays an ege; after- 
wards she covers all up with a series of lids made of circular 
pieces of cut leaves. The first-laid eggs develop into females, 
and these take a longer time to develop, so that the upper 
cells have given out their inmates before the lower. 
Mr. kh. L. Harrow showed the following plants in flower 
from the Royal Botanic Garden :—Aphyllanthes monspeliensis, 
Aquilegia truncata, Campanula Allionii var. hirsuta, Car- 
michachia Enysii, Corydalis sp. from China, Erigeron trifidus, 
Erodium trichomanefolium, Leucopogon Fraseri, Phyteuma 
anthericoides, Trientalis americana, Veronica catarracte var. 
compacta, Viola Zoysit. 
Mr. D. M‘GuLasHEN showed Erysimum orientale as a 
casual.
