digitules are missing (probably broken oft ). Anal ring with six very long 
setae which are contained in an unnsually long anal tube (b). Valves of 
anal operculum of irregular form (c), the extremity produced ; two short 
spines on the apical half of the inner margin and a longish, stout seta 
immediately outside the apical point. Margin {</ ) with numerous stout, 
sharply pointed, conical spines arranged in small clusters with a single 
larger spine in each interval. The arrangement and relative proportions 
•of these spines can be seen more clearly on areas where theV have been 
displaced, leaving their sockets (/) exposed. No stigmatic clefts or 
specialized stigmatic spines. Overall dimensions 7 by 5 mm. Length of 
denuded insect 4'o mm. 
Described from a single example, on the undersurface of a leaf of Pteros-

At the time of publication (loc. cit.) I was in possession of a single 
example only, which I was reluctant to destroy. I was able, therefore, 
to describe the external characters alone. I have, since then, obtained 
further material, both from Ceylon and from India, from which the 
following details have now been drawn up. 
The denuded insect (a), after being boiled in potash, is of the form in- 
dicated on Plate GVII (of my Monograph), fig. 3, which shows a diagram- 
matic view of the area occupied by the body of the insect. The derm of 
the dorsum is densely chitinous ; that of the venter very thin and delicate. 
At the centre of the dorsum is a prominent erect, horn-like process. At 
about midway between this and the anterior extremity is a smaller, 
irregularly tricuspid prominence ; and, at about the same distance from the 
posterior extremity, is a similar process. The position of the waxy plates
