populi, Bairensprung, and others, but differs so much that I can refer it 
absolutely to none, and am forced to consider itas new. Still it may be 
only a variety. 
3rd Genus, Aspidiotus, Bouche. 
1. Aspidiotus aurantii, mihi. 
(Trans., vol. xi., p. 199). 
I learn from Mr. Comstock, entomologist to the Department of Agricul- 
ture, Washington, that this species abounds, and does very great damage, 
on orange and lemon trees in California and Florida. I do not gather from 
him, however, that any description of it was published previous to my paper 
of 1878, so that, I presume, my name for it will be retained. 
While in Melbourne last year, I observed this insect in great numbers on 
orange trees there. But the fruit which has been sold in the shops here 
during the last few months seems to have been comparatively free from it. 
Probably, as in other countries, the pest has cycles of maximum and mini- 
mum frequency. 
2. Aspidiotus nerii, Bouché. 
I have lately found, on Coprosma, in the North Island, this species, 
which is exceedingly common in Europe, but seems to have hitherto not 
spread in this country. Its favourite habitat is the Neriwm oleander, and in 
France and Northern Italy it does very great damage to that and several 
other plants. In Melbourne I noticed many plants terribly infested with it. 
The puparium is whitish, and, as in all Aspidioti, round and flat. The 
Species may be recognized by the four anal lobes of the young insect (of 
which two are somewhat prominent) and by the form of the scaly hairs at 
the anal extremity of the adult female: these hairs have, some a rectangular, 
Some a serrated tip. 
4th Genus, Fiorinia, Targioni. 
1. Fiorinia astelie, mihi. 
Trans., vol. xi., p. 201, under the name Diaspis gigas, corrected in vol. xii., p. 292. 
It is to be noted that the larval form of the male of this species, that is, 
the stage succeeding the young insect, resembles not a little an adult female 
of Mytilaspis drimydis, showing the four anal lobes extending some way into 
the body, as in pl. v., fig. 5a, Trans., vol. xi.: but it is somewhat more 
deeply Corrugated, and of a greyish yellow colour instead of red. The form 
sl the puparium, which is quite distinct in the two species, will prevent 
mistake. In F. astelia the puparium of the male is long, narrow, thin, and 
on the under side bi-carinated. The puparium of M. drimydis more nearly 
tesembles that of M. pomorum, and has no keels. 
Amongst the type slides of Coccide deposited by me with the Institute, is 
ee the male larva of Fiorinia in the act of changing into the pupa.
