17,2 _ Morrison: Philippine Nondiaspine Coccidx 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 (10243). The generic characters already given 
should be sufficient to place this species, although here again 
reference may be had to Green ** for an extended description and 
figures, 
Fic. 80. Ceroplastodes cajani (Mask.), adult 
female; a, anal plates, X 165; b, spiracular 
spine, X 885; c, marginal spines, X 335. 
Genus COCCUS Linnzeus 
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 Lecaniwm. Four spe- 
cies, one of which is believed to be confined to the Philippines, 
have been collected in the Islands.
