species, while it will be observed from a comparison of the ~ 
original description of candida with those of seychellarum that 
there are no differences given with the exception of a few very 
slight ones in relative lengths of antennal segments and the dif- 
ferences in the color of the secretion covering the insect. Other 
writers have already noted the variation in the secretionary color 
Fic. 8. Icerya seychellarum (Westw.), adult female; a and }, different sorts of solid-center 
gland pores on body, X 640; ¢, leg, X 57.5; d, antenna, X 57.5; e, large open-center gland 
pore, secreting glassy threads, x 640. 
of seychellarum. The large gland pores with open centers and 
the presence of the numerous glassy threads in the secretion 
make this species easily recognizable. 
In addition to the collection records given by Miss Robinson 
for the two species, the following may be cited: 
LuzON, Manila, on Artocarpus integrifolia (coll. P. J. Wester), 
on Citrus decumana (coll. B. Arce 2594): Batangas Province, 
Tanauan, on Citrus nobilis (coll. Wester): Bulacan Province, 
Baliuag, on Artocarpus integrifolia (coll. Arce 2614) : Quingua, 
on Litsea glutinosa (coll. Arce 2616): Laguna Province, Los 
Bafios, on Psidium guajava (coll. Banks 18453), on Streblus 
asper (coll. Baker 10093). 
Icerya aegyptiaca (Dougl.). Plate 1, fig. 1.

This species does not appear to have been previously reported 
from the Philippine Islands, but the material sent by Mr. Mackie 
for determination gave the following records: Manila on Barleria 
cristata (coll. Arce 2606) and Morus alba (coll. Arce 2568). In 
addition it is known from Manila on Citrus (coll. Compere).
