LAKE WAKATIPU

on stony screes amidst a Flora that was truly Alpine. Mr. Howes 
is pretty confident that he saw * Erebiola butleri, Fereday, but a 
butterfly rushing swiftly over a scree has pretty well its own way. 
By industriously turning over stones Mr. Howes found an empty 
pupa-case of an Erebiola, together with several of the Arctiid, 
* Metacrias huttonis, Butl. He also found larvae of * Hyssia nullifera, 
Walk., in the stems of the “ Spear-grass/’ 1 A few of our old friends 
% Notoreas brephosata and *Arctesthes catapyrrha, completed the small 
company. It was indeed evident that it was quite too late in the 
season for day work at high altitudes, moreover the famous Alpine 
flowers were almost all over, a few belated specimens of the Shepherd’s 
Lily being almost the sole survivors. 
Another day we went about 1000 ft. up Mt. Alfred, a much lower 
mountain on the opposite side of the valley. Insects were more 
numerous but for the most part the same as occurred on the flat. 
The few exceptions were * Xerocopa cyameuta, Meyrk.; a Scoparm- 
like moth which would appear to be uncommon; the Ant, * Mono - 
moriam antarcticum, of the typical form ; two * Gicindela parryi, and 
another Beetle, a species of Odontria . 
In the wood at the highest point that we reached, Mr. Howes 
found under bark of Beech {Fagus ? fusca, Hook.) a number of the 
tiny Snail, *Laoma celia, Hutton, and several specimens of what Mr. 
Suter says is a new sub-species, to which he has given the name 
alboviridis. 
Mrs. Longstaff obtained by dredging in the Diamond Lake with 
impromptu instruments, besides * Diplodon menziesi, * Isodora lyrata, 
and abundance of Potamopyrgus badius and * Sphaerium novae-zea- 
landiae, a single specimen of Amphipepla ampulla. 
Land shells were not common, but one or other of the party 
picked up on the flat, chiefly under bark or logs:—several * Endo- 
donta ( Gharopa ) otagoensis, Suter, one E. sterkiana, Suter, one E. 
bianca, one E. ( Aeschrodomus ) barbatula , Beeve, two Flammulina 
pilsbryi, Suter, one of the very tiny F. feredayi , var. glacialis, Suter, 
one Thalassohelix traversi, E. A. Smith, and one * Laoma phrynia, 
Hutton. All these were small shells, and such as may be easily over¬ 
looked. We did not have the good fortune to enter the circumscribed 
area of distribution of the only large Hew Zealand land shells of 
the genera Placostylus and Pary pliant a. The poverty of the Hew 
Zealand land mollusca is indirectly shown by the rapidity with 
1 *Aciphylla sguarrosa , Forst., Nat. Ord. Umbelliferae ; the genus is confined to 
New Zealand. Not be confounded with the Spear-grass of India (see above, p. 70), 
which is a true grass.
