XVIT—THE 
where it is sometimes very abundant, especially early in 
the season. When at rest the wings are held flat and 
slightly extended from the body, with the tips divergent. 
The antennae are placed backwards on the top of the 
wings. The insect stands on its fore- and hind-legs, the 
latter bemg drawn forwards with the thickened hairy 
tibiae projecting beyond the costal margin. This quite 
breaks up the margin and gives the insect an unnatural 
‘appearance, with a possible resemblance to a small blackish 
lichen. The tarsi are irregularly placed and the palpi are 
curved inwards, their extremities almost touching in front 
of the head. 
The specific name is very appropriate, having refer- 
ence to the striking superficial resemblance of the hind- 
legs to those of a grasshopper. 
Mr. Philpott points out that this insect appears to be 
attached to Polystichum vestitum. 
THYLACOSCELES RADIANS. 
(Thylacosceles radians, Philp., Trans. N.Z. Inst., 1., 129.) 
(Plate XXXVIII., fig. 16 4, 17 3.) 
This very interesting species was discovered by Mr. 
Philpott at Seaward Bush, near Invercargill. 
The expansion of the wings is about % inch. Very like 
T. acridomima, of which it appears to be the southern represen- 
tative but the fore-wings, in both sexes, are nuch narrower. 
The fore-wings of the male are grey, finely speckled and streaked 
with darker grey, and with two very obscure paler marks on 
the outer half of the dorsum. The hind-wings and cilia are 
grey. In the female the fore-wings are pale brownish-ochreous, 
with grey blotches in the middle of the dorsum and at the apex. 
The hind-wings and cilia are very pale greyish-ochreous. In 
both sexes the thickened tufts at the end of the hind tibiae are 
black. 
The perfect insect appears in December and is fairly 
common in forest. Mr. Philpott considers that the food- 
plant of this species may be Polypodium dwersifolium.

Sub-family 7—CosMOPTERYGIDES. 
Head-smooth. Labial palpi long, recurved, acute. Maxil- 
lary palpi very short, appressed. Fore-wings with vein 10 fur- 
cate, 2 from near angle, 7 and 8 stalked, 7 to costa. Hind-wings 
lanceolate, 2-4 remote, parallel, 6 and 7 basally approximated or 
stalked. (Plate F., figs. 31-36.)

sparsely represented in New Zealand by the seven follow-

Labial palpi very long, slender, terminal joint longer than

There are three New Zealand species, all of which are

PYRODERCES APPARITELLA.

apparitella, Meyr., Trans. N.Z. Inst. xxi., 174.) 
(Plate XXVIIL., fig. 22.) 
y beautiful, but fragile-looking insect has 
occurred at Kaeo, Auckland, and Wellington. It is prob- 
ably fairly common and generally distributed throughout 
the North Island. 
The expansion of the wings is about 4 inch. The fore- 
wings, which are elongate and very narrow with vein 5 separate 
and 6 present, are bright golden brown with very distinct clear 
white markings finely edged with black; there is a very fine line 
in the middle of the wing from the base to 4; a rather broad 
line on the dorsum from the base, ending in a large white-edged 
yellowish patch, which is also connected with the costa by a 
winding black-edged white line; there are two other conspicuous 
very winding transverse lines, one before and one beyond the 
middle; another pale yellow mark on the dorsum beyond the 
middle; a small black-edged white mark is situated on the costa 
before the apex and a heavier mark at the apex. The hind- 
wings and all the cilia are grey with very faint pinkish reflec- 
tions; veins 6 and 7 are stalked. The top of the head and the 
palpi are white; the antennae are also white with sharp black 
rings; the eyes are brilliant crimson. 
The perfect insect appears in December and January, 
and frequents forests. It is also found in gardens and 
occasionally indoors. When at rest the wings are wrapped 
closely around the body, coming to a very sharp point. 
The antennae are curved outwards on each side; the palpi 
placed backwards over the head, the terminal joint reach- 
ing to the thorax. The insect stands on the tips of the 
tarsi of the fore- and intermediate legs, which are extended 
from the body, one hind tarsus also usually touches the 
ground, the other being elevated to the level of the wing. 
When the fore-wings are thus closed, the yellow dorsal 
markings of each join together and form one round and 
one elongate pale yellow spot on the back of the insect.

PYRODERCES AELLOTRICHA., 
(Proterocosma aéllotricha, Meyr., Trans. N.Z. Inst., xxi 175.) 
This species was discovered by Mr. Meyrick at Ham- 
ilton. 
The expansion of the wings is about 4 inch. The fore- 
wings are elongate, very narrow, long pointed; vein 5 separate, 
6 present; reddish-ochreous, tending to become whitish-ochreous 
round markings and towards base of dorsum; markings ochre- 
ous-white, closely irrorated with black; an irregular oblique fas- 
cia from 3} of costa not reaching dorsum, emitting a short streak 
from posterior edge above middle; an irregular somewhat 8- 
shaped spot in middle of disc, from upper part of which pro- 
ceeds an irregular streak to costa before apex; an irregular 
ochreous-whitish streak along termen from apex to tornus; a 
black apical dot; cilia light ochreous-greyish, round apex red- 
dish-ochreous, with a blackish basal line and two blackish apical 
hooks. Hind-wings with veins 6 and 7 stalked; grey; cilia pale- 
grey ochreous-tinged. 
The perfect insect appears in January.
