flabelliformis—Ed. G.N.), and the Pallid Cuckoo (Ouculus pallidus) 
and a plant bug (Cuspicona sp.), but as these only attack the larvae, 
the chances are in favour of the continued existence of this pest. 
This species completes its metamorphosis three and sometimes 
four times during the summer season, hence the necessity for 
vignerous and others for keeping it in check.

Vine Mora. 
Order— Lepidoptera. Section—Heterocera. Family—Sphingide. 
This is one of the most beautiful species in the Section, 
Unlike the former species (Agarista glycine) this moth is strictly 
nocturnal in its habits, and may be recognised by the peculiar 
whirring noise produced by the rapid movements of its wings when 
in flight. The larvæ are of a brownish green colour, averaging 2% 
in length, being quite smooth on the back and adorned upon the 
upper side of the posterior segment with a curved horn-like 
process, similar to that possessed by the familiar Silkworm. 
The pup: are encased in an oval shaped cocoon composed of a 
fine web, rendered very strong by aglutinous substance; the cocoon 
however is easily broken open by the moth when maturity reminds 
it that it has a mission to fulfil. Last year I found a caterpillar of 
this species, and noticing that it was preparing to spin, put it away 
carefully with the date duly recorded, and found that it emerged 
one evening after being 26 days in the chrysalis stage. The moth 
notified its existence by the sound already mentioned. 
Although the larvæ of this moth are more destructive than those 
of Agarista glycine, they are not so numerous, nor are the re- 
productive faculties of this species so marked as in Agarista glycine. 
It is therefore not to be feared to the same extent, but being of 
nocturnal habits, we frequently find that many leaves of a vine 
disappear mysteriously during the night, so that both the moth and 
i caterpillar may be captured after nightfall by the aid of a 
antern. j 
NOTES ON A TRIP TO CAPE OTWAY. 
Bx Mr. J. Dennant, F.G-S., &c. 
. A visrr to the Cape Otway district was planned a year ago and I 
was fortunately enabled to secure Professor Tate as a travelling 
companion. We started from Melbourne on the 9th of February, 
and endeavoured on reaching Geelong to induce Mr J. Mulder to 
join:us, but to his great regret previous engagements did not allow
