to the straight paired filaments that alternate with the inner series of curved 
filaments on the test) ; a ventro-marginal series of small simple circular pores. 
Disc of dorsum with conspicuous groups of 8-shaped pores (/ig. 3) correspond- 
ing with the tufts of short filaments on the disc of the test, viz., a median 
series, arranged more or less in short transverse lines ; a curved lateral series 
of five rosette-shaped groups on each side, situated internally with regard to 
the position of the spiracles; a small rosette immediately behind the position 
of each antenna; and a rosette on each side immediately exterior to the 
position of the anterior spiracles. On the ventral surface of the abdomen there 
are four or five transverse series of simple circular pores, and an irregular series 
of similar (but smaller) pores connects each spiracle with the margin. Colour 
of living insect greenish yellow, changing after death to dark reddish brown. 
Length of extended insect 0'75 toi mm. Breadth 05 too’'75 mm. 
Male unknown. 
On various orchids, e.g., Ophiopogon jaburan, Angroecum sesquipedale, 
and Cypripedium hamaldianum, in plant-houses, Peradeniya; on Calathea 
and Onczdium, West Indies; on Akeadza and various plants in plant-houses 
in Europe. 
A remarkably ornamental species ; easily distinguishable from its allies by 
the separation of the fringe into symmetrical bundles of filaments.
