MONOPHLEBIN A 
This subfamily is represented in the Philippines by species 
having the legs and antenne well developed, the latter 8- to 11- 
’ gegmented in the adult female, the body more or less covered 
dorsally with waxy, powdery, or cottony secretion, the anal ring 
dorsal and without sete, the derm usually closely crowded with 
pores and hairs over practically the whole surface, and ab- 
dominal spiracles in all stages. . 
Key to the Philippine genera of the Monophlebine.

slender, tapering; adult female usually secreting a distinct elongated

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-
