exposed. When there is a large batch in the one tree 
they often eat into the sapwood of the tree a little, form- 
ing shallow tracks in it. 
After wet weather, very often there is a manna-like 
exudation from the wounded part, which is sweet, and 
has a strong smell. This proves a great attraction, and 
a wholesome food for many other insects. 
Mr. Gallard also exhibited another moth (Ptilomacra 
senax), which is classified as a Liparid; but he was in- 
clined to think it should be in the Cossidae, as it appear- 
ed to be very closely allied to Culama rubiginosa, and 
was very often taken in the same locality. So far he had 
not been able to breed one of these, and he would be glad 
to hear if any other member had. This moth is from 2 
to 8 inches across the wings, is dark grey in colour, and 
has an abnormally wide combed antennae. 
NOTES ON THE BENT-WINGED SWIFT MOTH, 
LETO STACEYI. 
By L. Gallard. 
The adult is one of our largest moths, sometimes hav- 
ing a wing expanse of 91% inches. Although it has a great 
wing expanse, the wings are not nearly so wide trans- 
versely as those of the Zenzera, or wattle moths. The tex- 
ture of the wings is lighter, and the scales are not so 
thick, and are easily rubbed, off. _The front pair are cury- 
ed on the hind margin towards the end (hence the term 
bent-winged). The two front nervures are very strong, 
and the space between them has a mottled velvety appear- 
ance. The remainder of this pair varies from light brown 
to orange, and the hind part has a lovely water-waved ap- 
pearance, showing a light bluish sheen when the light is 
thrown upon it. They also have a pair of peculiar large 
eye-marks. The hind pair are a plain orange colour, and 
jn the male particularly are covered near the body with 
long hair, which gives them a lovely appearance. In this 
section there is also a triangular shaped band of dark 
brown in the front wing, but the remainder is of a lighter 
colour, which makes it look brighter. The body also is 
much lighter than that of the wattle moth. The head is 
narrow, antenne fine. The two front pairs of legs are 
very long and highly pubescent. The hind pair are much
