230 THE ORCHID REVIEW. 
handsome Disa X Veitchii, Dendrobium X rhodostoma, Cypripedium 
x T. B. Haywood, and various others. 
Many of the species from which Messrs. Veitch’s remarkable hybrids 
have been derived are also there as a matter of course, and among 
those noted in flower were Lelia crispa, the rare Masdevallia Barleana, M. 
amabilis, M. Veitchiana, Selenipedium Schlimii, Miltonia Roezlii, Epi- 
dendrum radicans, etc., and of those from which, so far as we know, hybrids 
have not appeared, were the handsome Odontoglossum Harryanum, 
Dendrobium glomeratum, Coelogyne speciosa, andthe remarkable Chondro- 
rhyncha fimbriata. A list of those in fruit could easily be compiled, for Mr. 
Seden continues his experiments in the old systematic way, but we will only 
mention capsules of Epidendrum vitellinum, remarkable for their glaucous 
character, and a batch of Sophronitis grandiflora, which will probably be 
heard of later on. It has been remarked that as seedlings from this species 
are usually slow growers it would be better to use it as the pollen parent. 
But there is the compensating advantage that it crosses very freely, and 
many of the reverse crosses which have been tried by Mr. Seden have 
refused to set. LEpidendrum radicans, for example, has been crossed with 
all kinds of things, and has always refused to set a single pod, though as 
pollen parent it has been used with great success. Mr. Seden should try to 
fertilise it with its own pollen, just as an experiment, for we know that 
capsules are produced in a wild state. It can scarcely be that there is a 
constitutional weakness about the particular individual growth at Langley, 
and it would be interesting to have the experience ofothers with this species. 
Many more interesting details could be written, but the facts will doubtless 
come out in due time, as the numerous seedlings reach the flowering stage. 
THE DENDROBIUM BEETLE. 
SoME information respecting the Dendrobium Beetle was given at pages 
136 and 164 of our last volume, and it would appear that more than one 
species has been introduced. into our collections. A very interesting article 
is given by Mr. R. Stewart MacDougall, M.A., B.Sc., in the Gardeners’ 
Chronicle for July 24th (pp. 48, 49, figs. 11-16), whence the following notes 
are condensed. 
In December, 1896, the author was asked to visit the Orchid house ofa 
large grower in Midlothian, where the Orchids were being ruined by some 
agency or other, and on examination many of the pseudobulbs were found 
to be tunnelled by the larve of a longicorn beetle. Later on the beetles 
were bred out from these larve at the Royal Botanic Garden, Edinburgh, 
and proved to be, as suspected, Diaxenes dendrobii (Gahan). The life 
history of the pest is now being worked out there, and as the experiments
