obsolete ; antenn rather longer than the thorax, ciliated, tapering to the 
tips; abdomen not extending beyond the hind-wings ; fore-legs longer than 
the others, slender, almost bare; wings broad, diaphanous, thinly covered 
with hairs; fore-wings slightly concave along the costa, hardly oblique 
along the hind margin, rounded at the anal angle; discoidal cell closed by 
a transverse angular nervure, the angle of which projects inwards; median 
nervure emitting four branches, the first of which springs from an abrupt 
bend in the second at the junction of the transverse nervure, the second 
about a third further from the third than from the first. Between the 
median nervure and inner margin are two nervures which unite in the 
dise, and form one nervure from thence to the hind-margin. Of these two 
nervures the one farthest from the hind-margin is hardly visible towards 
the base. Hind-wings with discoidal cell closed by a transverse angular 
nervure, and divided by a vein springing from the angle of the transverse 
nervure ; median nervure emitting four branches, the first of which springs 
from the second at about a third of the length of the latter, which is 
abruptly angulated at its base; the second branch more than half further 
from the third than from the first. 
Female.—Apterous. 
Not finding its generic characters entirely agree with any of the 
descriptions in the British Museum catalogue, I have described a new genus 
for this insect as above. 
Orophora toumatou, n.s. 
[From the specifie name of the shrub upon which the cases are found.] 
Male.—Ochreous grey; the long hairs on the body and base of the 
wings tinged with pale ochreous. 
Expanse of wings—12-5 lines. 
Length of body—5 lines. 
Hab.—Canterbury plains. 
Fig. B. represents the male perfect insect. 
Larva.—t have never seen the larva when full-fed. Its case measures in 
length about sixteen lines ; the exterior covered with pieces of stems of grass, 
from a line to five lines in length, laid on longitudinally and in the manner 
of thatch ; the interior thickly lined with fine silk. The cases are found 
fixed to twigs of wild Irishman ( Discaria towmatou), but it may be inferred, 
from the covering of the cases, that it probably does not feed on the shrub 
but upon the tussock-grass generally growing where the shrub is found. 
It is some years since I found the cases on Discaria towmatou, growing in 
the river beds of the Rakaia and Waimakariri, on the Canterbury Plains, 
and I did not find any case in its earlier stage before the larva had fed up 
and uet to the pupa state.
