130 THE ORCHID REVIEW, [May, 1923. 
sepals and petals yellowish, spotted with chestnut-brown; the lip white 
with some red spots in front of the yellow crest; the column wings usually 
dotted with red. In the variety flavens the sepals and petals are pale 
vellowish green spotted with yellow, and the lip wholly white. The variety 
phenanthum has reddish-brown sepals and petals.

Xxxlii., p. 149, Mr. T. D. Cockerell, of Boulder, Colorado, U.S.A., refers to 
the following Diaspine Coccidz, found on greenhouse Orchids; they are 
of interest on account of the locality, and, excepting the first, new host- 
plant records. Aonidia pseudaspidiotus was found by Mr. Knudson on the 
stems of Vanda teres in a greenhouse at Boulder, Colorado, and considered 
to be an oriental species. Mr. Cockerell says this species appears to be 
closely related to Aonidia crenulata, and in spite of its great resemblance to 
such species as Parlatoria pergandei thinks it is properly an Aonidia. 
Several years back A. pseudaspidiotus was found on an Orchid at quarantine 
at the port of San Francisco. Chrysomphalus dictyospermi was found on 
Coelogyne cristata, infecting the leaves, and Diaspis boisduvalii on 
Leliocattleya Victoria and Odontoglossum Rossii. 
NEOBENTHAMIA GRACILIS. 
HE peculiar habit of this species attracted attention at Kew directly it 
was received from Zanzibar, whence it had been sent by Sir John Kirk 
in 1884. In February, 1890, it flowered for the first time, when it proved 
to be anewtype. The distinct stripes and gland of the pollinia showed 
that it belonged to the Vandee, and to the sub-tribe Cymbidiz on account 
of the lip being adnate to the base of the column, and without a spur. 
N. gracilis is a vigorous grower, but somewhat loose and straggling in 
habit, for it grows naturally among bushes and avails itself of their support. 
The main stem is usually from 4 to 5 feet high. Secondary branches are 
produced at intervals, and as these develop aerial roots at the point of 
junction they form a ready means of propagation. The distichous leaves 
are drooping and about six inches in length. 
The flowers are produced on dense terminal racemes, fresh flowers being 
formed at the apex during a period of at least six weeks. The individual 
flowers are about ? inch across, white, except that the lip has a yellow 
median line and a row of purplish spots on either side. Well-cultivated 
plants will yield spikes with upwards of 30 flowers. N. gracilis is an 
endemic monotype, allied to the Asiatic genus Bromheadia, and should be 
cultivated in a warm house, selecting a fairly light position in order that 
the slender stems be satisfactorily ripened.
