Leonardos placing of this species in the genus Paleococcus is 
followed here without critical consideration. 
This species has been identified from a comparison of speci- 
mens received from Mr. E. E. Green collected on Michelia 
champaca at the Botanic Gardens, Singapore, April 8, 1916, by 
Burkill, and on Rhopaloblasta palm, Singapore, February, 1917, 
by Burkill, with a translation of Leonardos original description. 
This description, while not so detailed in some respects as is 
desirable, seems quite sufficient to establish the identity of the 
Singapore specimens. Mr. Green had tentatively placed these 
two lots of material under the manuscript names Icerya ordinata 
and /. pahnarum, respectively, but as careful a comparison of the 
structural characters of the two lots of specimens as is possible 
from the limited number of each present fails to disclose any 
differentiating characters, while the only difference indicated in 
Mr. Green’s notes is in the color of the secretionary covering, 
the surface coating of that of ordinata being lemon yellow, while 
palmarum is supposed to have a pure white coating. 
This species is briefly redescribed herewith, with particular 
emphasis on the structure of the derm pores and the setse. 
Adult female. — Ovate, broadened behind, somewhat convex; 
maximum length of specimens examined, 6.5 millimeters ; width, 
4.25; dorsally with a dense coating of white secretion usually 
strongly tinged superficially with lemon yellow, broken up into 
distinct plates, these broadly transverse in the center of the 
dorsum, bordered by a double row of square to oblong plates 
running clear around the body, with the outer, or marginal, row
