in fig. 215. In fact the insect is now, as it were, resting on a bed of cottony 
down, its head downward to the twig. The ovisac, in its upper portion, is 
divided by regular grooves; the under side is flat, having several short 
cottony processes radiating from its edge. It is now full of eggs, and these, 
rapidly hatching, produce the young insects which emerge through the 
cotton and go to seek their fortunes on the plant. I think the ovisac usually 
contains from 60 to 70 young insects. The extreme length, from the head 
of the female to the extremity of the ovisac, is sometimes nearly } of an 
inch, the height being about } inch. 
I have not been able to find a male insect of this, which is certainly the 
most curious species of the Coccide with which I am acquainted. The 
male of Icer; ya sacchari is also, I believe, unknown. 
I have now completed the description of the species Coccide proper, and 
in fact of all the insects which I am as yet able to relegate to well-defined 
genera. I have still to describe one species whose position I cannot deter- 
mine with certainty. Itis by no means the least beautiful of the family. 
My specimens have come from Pittosporum engenioides and Discaria toumatou. 
I am constrained to form from it a new genus, which I dedicate to my 
friend Dr. Powell who was the first to find it. 
PowELLi, gen. nov. 
The genus is certainly not one of the Diaspide ; it does not belong to 
the Lecanide, for it has not the abdominal cleft and lobes and the mentum 
is tri-articulate, nor to the Coccide proper, for there are no anal tubercles, 
and the feet are clearly different. In some of its characters it bears a 
resemblance to an Aphidian insect which is very common here upon the 
young leaves of very young Eucalypti, although I do not think that Powellia 
belongs to the Aphides. Is it not possible that it may be a link between 
the two families Aphis and Coccus ?

Plate VIII, fig. 22. 
The female insect is shown in fig. 220. Itis at once apparent that, in 
some respects, it has the characters of the Lecanio-diaspide; there is the 
test covering the body and there is the fringe. But further examination 
shows that it differs a good deal from that group. First, there is an evident 
division between the test over the thorax and the test over the abdomen; 
the fringe of the latter is seen to overlap that of the former. Moreover, the 
eyes are faceted, which is not the case in the Lecanide. ^ Again, there is 
no abdominal cleft, 
"The first peculiarity of the species is that it seems to have four well 
defined wings. If this were really the case, as the insect is undoubtedly a 
female (for it has a mouth), it could not belong to the Coccide, But I am
