368 THE ORCHID REVIEW. [DECEMBER, 1906. 
DIPLOMA AWARDS. 
The subjects of the special competition were Cypripedium Fairrieanum 
and its hybrids, and the following awards were made :— 
CYPRIPEDIUM FAIRRIEANUM.—First Diploma to C. Fairrieanum dark 
var., from Messrs. Sander & Sons. 
C. FAIRRIEANUM Hyprips.—First Diploma to C. X Germaine Opoix 
Westfield var.; Second Diploma to C. X Baron Schroder punctatum, both 
from Francis Wellesley, Esq. 
The Scientific Committee on this date had several Orchids before it :— 
BonaTgeA UGAND# (Rolfe).—This Orchid, to which at the last meeting 
a Botanical Certificate was recommended, was commented upon by Dr. 
Masters, who drew attention to the remarkable form and size of the 
rostellum, the length of the caudicles of the pollinia, which fitted into long 
Fig. 47. THe CaTTLeva FLy (nat. size and magnified). 
tubes at the sides of the rostellum, and the length of the ape, which 
reached to between 5 and 6 inches long. 
Uncommon Orcuips.—A species of Pleurothallis from R. I. Measures, 
Esq., and Oncidium Waluewa, Rolfe (Waluewa pulchella, Regel), from 
H.T. Pitt, Esq., of Stamford Hill, were shown at this meeting. Mr. Rolfe 
undertook to report on the former at the next meeting. 
CATTLEYA FLiy.—Mr. Bowles showed pseudobulbs of newly-imported 
Cattleyas, which were badly infested with the larve of the Cattleya fly, 
Isosoma sp., a pest too well known on Cattleyas. Mr. Bennett-Poé 
suggested that the only way of dealing with the trouble is to collect 
the affected pseudobulbs, which turn black, and burn them. [Fig 47 is 
a photomicrograph of this insect, the small figure on the right showing it 
natural size, the wings in this case being invisible.—Eb.].
