THE ORCHID REVIEW. 149 
be traced to importations of Cattleya labiata, but the earlier ones appeared 
before the re-discovery of this species. Then C. Triane is sometimes in- 
fected, and probably before the plants come home ; and either this or some 
other fly has been sent with Lelia purpurata. It is hardly necessary to 
point out that all Saccolabiums are from the Eastern tropics. In short, it 
would be interesting to know precisely where the fly comes from, how to 
combat the pest when found, and also whether we have more than one 
species to deal with. It would also be useful to know whether the fly 
comes out at other seasons of the year beside the spring. Information on 
any of these points, and particularly the methods used by those who have 
succeeded in exterminating it, would be very acceptable.

LAELIO-CATTLEYA x DORIS VAR. VITELLINA. 
WE have received through Messrs. James Veitch & Sons the two-flowered 
inflorescence of a beautiful hybrid from the rich collection of Baron Sir H. 
Schréder, The Dell, Egham, which was described about three years ago by 
Mr. J. O’Brien, under the name of Lelia X vitellina (Gard. Chron., 1893, 
Xiii., p. 365, fig. 53). It was originally remarked that the parentage not 
having been recorded could only be guessed at, though the supposition was 
that L. harpophylla was one of the agents in its production, and Lelia 
Perrinii probably the other, most likely the seed bearer. The author, how- 
ever, added, ‘I have not yet had the opportunity of examining the pollinia 
of the new hybrid, and therefore cannot say how they stand with relation 
to true Lalia.” This point we can now set at rest. On examining the 
pollinia we find them precisely as in Lzlio-cattleya, that is, with four large 
pollinia and four much smaller ones at the other end of the caudicles. 
Lelia harpophylla was evidently one parent, as is evident from the very 
characteristic shape of the lip, together with the colour of the flower, but it 
is equally certain that some Cattleya of the labiata group was the other, as 
might originally have been inferred from the shape of the petals. There is 
no perceptible approach to the very characteristic lip of Laelia Perrinii or to 
any of the hybrids from it—the deflexed apex of the lip mentioned by the 
author comes from L. harpophylla, as is evident enough on comparison— 
besides which it may safely be prophesied that any hybrid between L. har- 
pophylla and L. Perrinii will have narrow petals. After consideration of 
all the facts we believe that the second parent was a light form of Cattleya 
Trianz, which would make it a variety of ee x Doris (supra, 
II., pp. 79, 111), to which it bears a kabl i chiefly differ- 
ing in having only a trace of purple on the front lobe of the lip. The 
agreement in the flowering period of the species now suggested as parents 
is also a point not to be overlooked. The flowers of the present variety are
