single nervure, are oval, and estend far beyond the extremity of the 
abdomen. The abdominal spike, which has a tubular sheath of larger size 
and length than in Aspidiotus, is double and long, but does not reach the 
tip of the wings. 
The legs are hairy; femora and tibiæ about the same length, but the 
former thicker than the latter; tarsi thick and spindle-shaped, ending in 
the usual single claw. The great distance between the first and second 
pair of legs gives the insect a peculiar bg uas: 
2. Diaspis rose, San dberg. 
Plate VI., fig. 9c. 
This also is European. It occurs here on rose trees at Governor's Bay, 
in Mr. Potts's garden. The puparium is flat and white, and the discarded 
pellicles on one side. The adult female is of a deep red colour, elongated 
in form, distinguishable from all other species by the size of the cephalic 
region and the deep corrugations of the body. Its appearance is more 
striking than that of any other species of the Diaspide, and the contrast 
of the blood-red head and thorax with the bright yellow abdominal region 
is curious. 
The cephalic region, mushroom-shaped, is quite smooth. There is no 
appearance of rudimentary antenna. The body has four large corruga- 
tions, nearly equal in size, and on the last two are a few spiny hairs. The 
abdomen, broken by serrations, ends in two lobes with a depression between 
them. The pygidium has five groups of spinnerets, but the side groups are 
almost continuous. The upper group has about 20 openings, the side ones 
50 or 60; there are no single spinnerets but on each side 8 or 4 rows of 
large oval openings forming arches. 
The young insect is brown, oval, with the head a little flattened 
anteriorly ; the legs and antenne and abdominal hairs as in other species. 
The cocoon of the male is white, cylindrical. I have not yet a specimen 
of the perfect insect. 
3. Diaspis gigas, sp. nov. 
Plate VI., fig. 10. 
I found this species on Atherosperma nove-zealandie, a North Island tree, 
of which Mr. Armstrong gave me a branch some months ago. I believe it 
best, as a rule, to use the name of the tree on which a scale-insect lives as 
its specific name, but as I have already used this particular name in the 
case of an Aspidiotus, I prefer, in order to avoid confusion, to call the 
present species by a descriptive title. I have lately found it in abundance 
on a species of Astelia, in Riecarton Bush. It is the largest of the Diaspidw 
which has yet come under my notice ; the puparium of the female is some- 
times more than } inch long and pẹ inch wide; the female reaches yy inch - 
in length, : i |
