310 Cerococcus. 
CEROCOCCUS ROSEUS, sf. nov. 
(PLATE CXVII.) 
Test of aduit female (7g. 2) with dorsum completely concealed beneath 
dense conical or rounded tufts of rosy pink fibrous secretion, arranged, 
apparently, in four series, and a marginal series of tapering rose-red fibrous 
processes. Owing to the crowded disposition of the insects, I have been unable 
to determine the exact number and arrangement of the dorsal and marginal 
secretionary processes. It has been found impossible to isolate a single - 
unbroken individual. The figure on Plate CXVII. is an attempt at a recon- 
struction, founded on many separate fragments. There is the usual elevated 
anal tube at the posterior extremity. Length (inclusive of processes) from 5 to 
8mm. Breadth, approximately, 5 mm. 
Male puparium unknown. 
Adult female insect broadly oval or approximately circular. Terminal 
abdominal segments abruptly narrowed ; anal lobes typical of the genus, the 
sete long and stout ; median plate dentate on its distal margin (jig. 3) ; anal 
ring with eight stout hairs. Dorsum crowded with 8-shaped glands of two 
sizes (fig. 4), disposed in more or less definite vortices. Many small paired 
glands on venter of abdominal segments. Antennz and limbs rudimentary, the 
latter in the form of stout curved claws. Cribriform plates (jig. 5) comparatively 
large, slightly concave; five or six on each side, usually in pairs, near base of 
abdomen. Length 2°5 to 3°5 mm. Breadth 2 to 3 nm. 
On small branches of undetermined trees. Trincomali. Collected by Major 
Yerbury. The insects are crowded in dense masses, completely encircling the 
twigs, in such a manner that the form of the individuals is quite obscured.
