reach the definite conclusion that it is not Pseudococcus glaucus , as 
originally described by Maskell, from the Maskell material of which 
the preadult female was obtained. The writer has not been suc¬ 
cessful in associating these specimens with any of the species de¬ 
scribed by Maskell or others, and although reluctant to describe it 
from the limited material available for study, he believes that it 
can be readily recognized from the description whenever it may be 
found in the future, owing to the apparently unusual and dis¬ 
tinctive cerarian characters, and that its association with the species 
complex discussed in this paper makes its characterization prac¬ 
tically necessary. 
Fm. 1 Pseudococcus arnbiguus, adult female: A, apex of abdomen, X96; B, posterior coxa, X96: C, pre- 
apical cerarius, X424; D, apical cerarius, X424; E, apex of head, X96 
Although no definite distribution or host data are available, it is 
assumably a New Zealand species. 
The types are in the United States National collection of Coccidae.

Adult female. —External appearance well described by Fullaway (5), and 
others, and not treated here; size of body, as mounted, varying considerably; 
well-developed individuals about 4.5 mm. long by 2.5 mm. wide; derm entirely 
membranous; antennae normally 8-segmented, the average lengths of the seg¬ 
ments of several individuals in microns as follows: I, 67; II, 68; III, 43; IV, 31.5; 
V, 41; VI, 34; VII, 41; VIII, 98 ; legs not uriusual, hind coxae with a varying number
