rectangle, nearly straight from the angle to the apex; outer 
margin slightly convex, and sinuous, or elongate-sigmoidal to 
the extremity of submedian branch (but unfortunately this 
part of the wing is chipped away); costal vein arched, with well- 
defined pre-costal veinlet projecting into the lobate sub-basal 
angle ; sub-costal branches and radial emitted at equal distances, 
their points of emission forming an unbroken oblique line with 
the lower disco-cellular veinlet, which is about four times the 
length of the upper ; second and third median branches emitted 
slightly nearer together than the first ana second. Type—D.

LARV: OF N.Z. GEOMETRINA, &c. 
—— > -—— 
BY ALEX. PURDIE, M.A. 
—-— <> 
Mr. Meyrick, at the close of his Monograph of the N.Z. Geo- 
metrina, just published in the Transactions of the N.Z. Institute, 
gives descriptions of the larvee of some N.4. Geometrina as given 
by Professor Hutton, at the same time questioning whether the 
species had in all cases been certainly identified. Having been 
working at this branch of the subject for some years now, I have 
thought it well to publish here the results of my own observa- 
tions on the different stages of our Geometrina. I also take this 
opportunity to express my personal indebtedness to Mr. Meyrick 
for the valuable work he has done among our Lepidoptera. 
After being so long harrassed by the incompetence of previous 
workers, and the consequent accumulation of synonymy, it is a 
relief to find the investigation of our Lepidoptera in the hands 
of one so equal to the task as Mr. Meyrick has proved himself to 
be, and it is to be hoped that he will speedily turn his attention 
to the other groups yet untouched, as, for instance, the Noctuina, 
a group wherein revision is sorely needed. In this paper there 
will sometimes be occasion to refer to descriptions of larvee pre- 
viously published by me in this journal, and, to avoid repeating 
the descriptions in such cases, a reference to the number and 
page of the journal containing them will be given.
