Material insuffieient and also unsuitable for diagnostic purposes. The examples 
consisted of a few females and one male. 
Pulvinaria psidii Maskell.

Prof. Zimmermann 9. (Nr. 8). 
Several adult females. The females of this species closely resemble those of 
Pulvinaria floceifera, Westwood; but they are distinguishable from the latter by the 
divided and serrated marginal spines and also by the much shorter ovisac. 
Ceroplastes subsphaericus n. sp. (Newstead). 
Test of old adult females thin, divided into large lateral plates with nuclear 
centres; dorsum forming a large hemisphaerical or dome-shaped mass, at the sides 
of which the wax is so thin that the dark colour of the inseet shows through. 
Length 6, height 5 mm. 
Adult female denuded of the test. subspheroid with a faint submedian con- 
strietion; caudal process rudimentary, conical. Integument horny; dark, shining, 
castaneous; sides irregularly punctate. Outline of Venter more or less eircular. 
Antennae of 7 segments; a paraitized example has only 5 segments. Stigmatic clefts 
with a group of large pointed spines, sorrounded by numerous conical ones. Legs 
normal. Derm cells small eireular, outline not clearly defined, and in the centre of 
nearly all of them is seated a minute spine. 
Length 4,75, height 4,50 mm.

The tests of all the individuals were more or less imperfect; but the marginal 
plates were well marked in several individuals, There was no trace of colour in 
any of them, and if present in fershly collected specimens it had been removed by 
the alcohol in which they were preserved. In its external form it somewhat resembles 
Ueroplastes eistudiformis (Townsend MSS) Oockerell, but the test is much more rounded 
dorsally and laterally. The adult female when denuded of the wax is distinguishable 
by its sub-spheroid form, its heigh being nearly equal to its diameter; the base of 
attachment is also eondiderably less than the greatest diameter of the body. Nearly 
all the examples had been attacked by the larva of a chaleidid parasite: measuring 
l mm in length.
