Morrison : Philippine Nondiaspine Coccidse

d \ Body usually with the posterior extremity cleft, anal opening at 
the anterior end of this cleft and covered by a pair of trian- 
gular plates; these characters more or less obscured in the 
species that are covered with wax, Coceinas. 
d \ Posterior extremity of body not cleft, sometimes more or less in- 
dented; without plates over anal opening; body usually covered 
with cottony or mealy secretion or inclosed in a sac, rarely 
naked - Daetylopiinae. 
a 2 . Abdomen terminating in a compound segment or pygidium; legs want- 
ing; body covered by a firm waxy scale readily separable from the 
insect and made up in part of larval exuviae Diaspinas. 5 
monophlebina: 
This subfamily is represented in the Philippines by species 
having the legs and antennae well developed, the latter 8- to 11- 
segmented in the adult female, the body more or less covered 
dorsally with waxy, powdery, or cottony secretion, the anal ring 
dorsal and without setae, the derm usually ^losely crowded with 
pores and hairs over practically the whole surface, and ab- 
dominal spiracles in all stages. 
Key to the Philippine genera of the Monophlebinse. 
a\ With not more than three pairs of abdominal spiracles; body hairs 
slender, tapering; adult female usually secreting a distinct elongated 
posterior ovisac (one exception) Icerya Sign. 
a 2 . With more than three pairs of abdominal spiracles; adult female with 
more or less waxy or mealy secretion, but without ovisac. 
b\ Dorsal body hairs stout, not tapering, bluntly rounded at apices; 
with seven pairs of abdominal spiracles Lophococcus Ckll. 
6 s . Dorsal body hairs slender, tapering, acute at apices; adult female 
naked or more or less covered with mealy secretion dorsally; with 
seven pairs of abdominal spiracles Drosicha Walker. 
In this subfamily a number of males, without females, have 
been described from the Philippines. Unfortunately it has 
not been possible to connect more than a single one of these 
with already described females, and as they are given in Miss 
Robinson’s paper no further mention is made of any but the 
one which has been placed in synonymy. 
Genus ICERYA Signoret 
The usual, but superficial, distinguishing character of this 
genus is the development of a posterior ovisac in the adult fe- 
' Not discussed in this paper.
