Mr. Gray pointed out that the deposit at Wainui, Akaroa Har- 
bour, was of some commercial value as polishing powder, or tri- 
poli. It was two feet in thickness, and only covered by a toot or 
two of surface soil.

dark brown, with transverse fulvous bands ; fore-wings with a sub- 
apical, white-pupilled, black occellus ; hind-wings with anal angle

Leucania, Ochs; Leucania purdu, n.sp.—Male; fore-wings dark 
pinkish cedar colour, with several dashes of bright ochreous yel- 
low, cilia pale. Hind-wings dark fuscous, paler at the base. Ex- 
panse of wings, 1” 10.”

(6) ‘‘ Occurrence of a species of Ophideres, Bois., new to New 
Zealand,” by R. W. Fereday. Female: body ochraceous and pale 
ferruginous grey mixed; fore-wings too dilapidated for descrip- 
tion, but indications of pale ferruginous grey clouded with ferru- 
ginous brown and purplish-grey markings; hind-wings luteous 
with broad black border abbreviated towards anal angle, and very 
broad curved and abbreviated black discal band. Expanse of 
wings 42.”

(7) ‘« Note on a peculiar neuration in the wings of some indi- 
viduals. of Pevcnodaimon pluto, a New Zealand Butterfly,” by R. W. 
Fereday. The peculiar neuration consists in the uniting of the 
costal nervure with the first sub-costal nervule before reaching the 
costa. Inthe ordinary specimens the costal nervure extends to 
the costa in the usual form, and the first sub-costal nervule is 
absent. Out of 55 specimens examined, there are 11 males and 
1 female having the peculiar neuration. 
The President called attention to the curious fact that such a 
usually constant structure as a main nerve of the wing should 
occur under two different forms in this one species.
