E. ERNEST GREEN, REMARKS ON COCCIDAE. 315 
close to the larval pellicle: sides more or less distinctly 
broadly radially fluted. Colour bright fulvous to castaneous, 
the larval pellicle reddish : semitranslucent. Diameter 2.5 mm. 
Male puparium (fig. 2) elongate, subeylindrical, slightly 
flattened dorsally, with median erenulate ridge (formed by the 
larval pellicle), the posterior extremity raised and operculate. 
Colour reddish castaneous. Length 1.5 mm. 
Nymphal test of female similar in form to the adult, but 
smaller, more flattened, and of a dark reddish colour. 
Adult female, removed from test (figs. 3, 4), distinctly tri- 
loben, the respiratory processes arising from the lateral clefts 
and the caudal process from the posterior cleft, Respiratory 
process terminating in a triangular densely chitinous plate 
(fig. 6) carrying two compact groups of grandular pores: each 
pore with a central lumen and 5 or 6 radiating lines, its 
margin crenulate (fig. 7). Dorsal spine (fig. 5) densely chitinous, 
with a broad circular base, surmounted ou a slender fleshy 
stalk. Anal ring consisting of 4 chitinous plates which have 
a tendency to coalesce in pairs (anterior and posterior): some- 
times the anterior plates are confluent and the posterior plates 
separate: each anterior plate gives rise to two, and each 
posterior plate to three stout hairs, making ten in all. Caudal 
process stout, short, densely chitinous: the extremity irregu- 
larly dentate. A submarginal series of from 16 to 18 clusters 
of small circular pores completely surrounds the body of the 
insect. Diameter 2 mm. 
Prof. Cockerell distinguishes his insect from 7. decorella 
by the absence of ‘ribbing’ on the test of the adult female. 
Many of my examples show a very distinct fluting on the 
sides of the test. This character may become obliterated when 
the tests are massed together. I consider that awrantiaca is 
very closely allied to decorella, from which species it may be 
separated by the very much larger chitinous perforate plates 
which are nearly three times as large as those of decorella ;
