SCIENTIFIC COMMITTEE, 
CaTTLEyYA Friy.—Mr. Sanders reported that the shoots of the Orchids 
shown by Mr. Bowles were undoubtedly infested by the so-called Cattleya 
Fly (Isosoma Orchidearum), a hymenopterous insect belonging to the 
family Chalcididez, the members of which are parasitic on other insects as 
arule. This family is nearly allied to the Cynipidee, or true gall makers. 
He could not recommend any remedy but the very obvious one of burning, 
or in some other way destroying the infected shoots, and the present would 
be a very good time for this, as most of the insects are in the pupal stage, 
just ready to emerge. 
OnciIDIUM WALUEWA.—Dr. Masters reported that he had examined ¢his 
plant, and could find nothing sufficiently remarkable in its structure or 
history to entitle it to a Botanical Certificate (see note at page 20). 
PLEUROTHALLIs sp.—Mr. Rolfe reported that he had not yet succeeded 
in identifying the species exhibited at the last meeting. 
‘MALFORMED OrcHIDs.—Dr. Masters showed, on behalf of Mr. McBean, 
of Cooksbridge, a specimen of Odontoglossum crispum in which all the 
parts of the column which are usually confluent were developed in the form 
of free petals, resulting in the formation of a double flower. Mr. Bennett- 
Poé showed a Cypripedium in which the dorsal sepal was doubled, on 
which Dr. Masters will report. 
HYBRID ORCHID.—Mr. Douglas showed flowers of an Orchid obtained 
from seed of Lelia harpophylla crossed with pollen of L. purpurata, in 
which the only trace of the latter in colour was a small purple spot in the 
front of the lip. Dr. Masters will report on it.
