NOTES ON SOME OF OUR VICTORIAN MOTHS. 
By J. F. MULDER. 
Read before the Geelong Field Naturalists’ Club. 
Order—Lepidoptera. Section— Heterocera. 
Family— Sphingide. i 
Tur first moth I shall notice is one belonging to the aboye- 
family. In January, 1897, a large caterpillar was brought to 
me from Highton, near Geelong; it was about two inches long, 
ofa brown colour, with two lemon coloured stripes along the- 
sides, also eight blotches on the back and the same number of 
short bands connecting the two side stripes together, all of the 
same colour, each stripe being at an angle of about 45 degrees. 
The horn on the end of the posterior of the caterpillar being: 
red. The insect was very restless and would not feed; thinking 
it might want to change, L put some earth in the bottle with it, 
it buried itself at once in the earth, and on looking at the 
caterpillar on the 4th of February, it had changed into a. 
chrysalis; this was ofa reddish brown colour, about 14 inches 
long, and it had a trunk or proboscis about i of an inch, 
partly curled up. The perfect insect emerged on the 28th of 
February, being, roughly Speaking, about a month in the 
chrysalis state. The moth is about 22 inches across the wings, 
with beautiful brown blotches, its body being banded with 
black and red stripes, one of the bands behind the thorax 
being white, which gave it a very pretty effect, the proboscis 
being also long and red. This moth is called Protopace (Burm), 
Convolvuli (Linn), or the Convolvus Moth.* 
The commonest Hawk Moth we have here is the suffused. 
Hawk Moth, Cherocampa Scrofa (Bdv.), this is often captured 
about Geelong in the month of January. The fore wings are 
a rich brown, hind wings, crimson with black border. Cater-

Convoluli) of Europe, I find although the perfect insects appear tho same, 
neither the caterpillar or the chryealis are alike, the marking on the 
caterpillar of the European species being different, and the chrysalis being 
without the long trunk of our species, consequently our moth must be 
- f the same family. I secured a second specimen 
an undescribed species 0 \ 
of this moth a few days after, which was probably the female, as it was. 
not so brightly coloured as the first one described.
