318 THE ORCHID REVIEW. [OCTOBER, IgI0. 
The question is, canI kill the maggots without destroying the seedlings? » 
If so, how am I to proceed? I have only found it in the warmest houses, 
and only where I have sown the seed on sphagnum as stated, and that is 
where it appears to breed and do most harm. I have hundreds of seedlings 
raised this year, and had it not been for the ravages of this fly—that must — 
deposit its eggs in the moss—I might have had thousands. You will also 
see, I believe, a sort of dark-coloured eel worm, but I have not noticed any 
damage to developing seedlings by it, though I have often found them in the 
moss. Any information you can give me through the Orchid Review, will 
be thankfully received. H. A. INNESs. 
[We have several times had complaints about this maggot, and believe 
that no method of checking it has yet been discovered. The most hopeful 
method which we can suggest is to prevent the flies from laying their eggs 
in the compost, if it can be done, and this raises the question as to when 
the eggs are laid. If the fly is the one so commonly captured by the 
Pinguicula, there would seem to be a constant source of infection in our 
houses. We have submitted the specimens to an expert, in the hope of 
getting them identified, as a knowledge of the insect and its habits may 
disclose some method of dealing with it.—Ep.] 
THE HYBRIDIST, 
ONCIDIODA CHARLESWORTHII.—The flowering of a very interesting 
generic hybrid between Cochlioda Neetzliana ¢@ and Oncidium incurvum 
é in Messrs. Charlesworth’s establishment at Haywards Heath was 
mentioned at page 266, and the plant was exhibited at the R.H.S. Meeting 
held on August 30th. In habit and in the slender erect spike it recalls a 
much dwarfed edition of the Oncidium parent, but the flower is modified in 
Structure and colour. The flowers are on the whole most like the Oncidium 
in structure, but the sepals and petals are broader, and the lip shorter, 
while the colour may be almost described as carmine red. It will be 
interesting to see the plant when it becomes stronger. 
LE#LIOCATTLEYA x Timon.—A pretty little hybrid raised in the collec- 
tion of the Right Hon. J. Chamberlain, M.P., Highbury, Birminghan, it is 
said from Cattleya bicolor Grossii x Leliocattleya Ingramii. The flowers 
are most like those of the Cattleya parent in shape, and the sepals and petals 
are light purple in colour, while the lip is much deeper purple, with the 
white blotch on the isthmus so characteristic of the seed-bearer. Flowers 
from two plants are sent, one of which has small but distinct sides to the 
lip, the other is totally without side lobes, and the white blotch on the 
isthmus is narrow and less distinct. Very similar flowers from another 
plant were sent last year, when we suspected the parentage, but Mr. 
Mackay remarks, ‘“‘ we have not the least doubt about the parentage.’”’ The
