17,2 Morrison: Philippine Noncliaspine Coccidse 189 
Genus CEROPLASTODES Cockerell 
The species of this genus are characterized by the presence of 
a glassy test which retains its stout oval shape while the adult 
female shrinks and shrivels into the anterior end as she deposits 
her eggs. This test is variously ornamented externally accord- 
ing to the species, and is usually extremely brittle, at least in 
dried specimens. Only a single species has been collected in 
the Philippines so far. 
Ceroplastodes cajani (Mask.). 
Eriochiton cajani Maskell, Ind. Mus. Notes 2 (1891) 61. 
Specimens which are apparently this species, although in very 
poor condition, are in Mr. Geo. Compere’s collections from Ma- 
nila, the first lot from guava (1221), the second on an unnamed 
host plant (102 A3) . The generic characters already given 
should be sufficient to place this species, although here again 
reference may be had to Green 12 for an extended description and 
figures.

Genus COCCUS Linnaeus 
This genus, as used here, agrees with the use in the Fernald 
Catalogue and consequently takes in a number of the species 
described by English entomologists under Lecanium. Four spe- 
cies, one of which is believed to be confined to the Philippines, 
have been collected in the Islands. 
Key to the Philippine species of Coccus.

lateral; body more or less distinctly triangular. 
F. Marginal spines distinctly shorter than smallest spiracular spines; 
anal plates extremely elongate; with a fringe of ovisac in adult 
female Protopulvinaria longivalvata Green.
