ACIDALIA OCHRATA. 85 
the plants supplied. Still, bemg so small, the frass 
was hardly perceptible; as time went on it became 
more apparent that they ate only, or, at any rate 
principally, the withered flowers of the Galum. 
During the month of August, as long as this plant 
could be obtained in bloom, it was continued as food ; 
when this could no longer be obtained I had to seek 
some other food, and early in September I tried flowers 
of golden-rod. The larvee took to this readily enough, 
although evidently not a natural food, as the golden- 
rod did not grow in the district where the moths were 
taken. I simply tried it because I had it growing in 
my garden. Mystock of this plant failing, Mr. W. H. 
Grigg, of Bristol, kindly sent me a weekly supply of 
it by post until the middle of October, when flowers 
could no longer be obtained. By this time about ten 
of the larve had fed up much in advance of the rest of 
the brood, and almost gave me hope that, provided I 
could get them food, they might be induced to feed up 
this year. I pondered as to what food | could procure, 
when Crepis virens suggested itself to me, from the 
fact of recollecting that a species of Crepis was very 
plentiful in their habitat. Ovrepis virens being a late 
flowering plant and common on Blackheath, there was 
not much dithculty in getting flowers of it to try, and 
it proved a complete success. Some of these flowers 
were placed in a glass cylinder, with a few broken 
pieces of flower-pot, ight soil, and moss, which were 
kept moist, but not wet, having a free drainage. The 
cylinder was kept in a warm room, and the ten forward 
larvee now fed up rapidly, and by the 1st November 
the first one had spun up. I immediately dispatched 
one of the largest to Mr. Buckler, who has secured 
three drawings of this long-desired species. I may 
mention that at first I had tried the coast Crepis, but 
then only the leaves. They did not apparently care 
for them at all, or, in fact, for foliage of any kind. 
Flowers when withered appeared to be most to their 
taste.
