17,2 Morrison: Philippine Nondiaspine Coccidse 181 
Young ( embryonic ) larva . — Elongate oval, about 346 y long 
by 150 j a wide, antennae 6-segmented, the third and sixth longest, 
legs small, tarsal claw with denticle, all digitules long and slen- 
der; with a notch opposite the anterior spiracle, bordered in 
front by two and behind by one spear-shaped spine and with a 
single row of relatively large pores leading to spiracle; anal 
ring surrounded by a chitinized area, with six or eight setse. 
This species has been described from several females mounted 
on slides and some additional unmounted material, all collected 
on Mangifera indica at Isabela, Basilan, December, 1918 ( S . A. 
Reyes), and forwarded by Professor Baker under No. 10102. 
The types are in the United States National collection of 
Coccidse. 
This is the smallest species of this genus known to me. In 
its morphological characters it seems quite close to Tachardia 
aurantiaca Ckll., from which it differs in size, in having circular 
apices to the spiracular processes, with only a few spines and 
pores, instead of having a large triangular cap with a cluster 
of spines at one end and of pores at the other, and in other 
characters. 
COCCIN^E 
Members of this subfamily should be readily recognizable from 
the characters given in the subfamily key, since all the species 
have the pair of anal plates well developed, and all but Cero- 
plastes and Vinsonia show the anal cleft distinctly, while the 
heavy coating of solid wax covering the species of these genera 
is sufficient to distinguish them from any other Philippine coc- 
cids, with the possible exception of Tachardia. Species repre- 
senting nine genera of the subfamily, as they are at present 
recognized, have been collected in the Philippines. 
Key to the Philippine genera of the Coccinse. t 
a\ Marginal spines slender, linear, at most somewhat dilated and frayed 
at apices. 
b 1 . Body of female covered with and adherent to a thick coating of waxy 
or glassy secretion; spiracular spines usually numerous, stout, 
conical or bullet-shaped, clustered or spread out along the margin 
of the body. 
c 1 . Cephalic apex of body separated from remainder by a distinct su- 
ture; covering secretion of body extended into fingerlike pro- 
longations, the whole giving the appearance of a 7-rayed star 
with hemispherical center.. Vinsonia Sign. 
c\ Without a separated cephalic lobe; waxy covering of body not pro- 
truding as in the preceding Ceroplastes Gray.
