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. My stock 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 larva 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 I 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. Crepis virens being 
a late-flowering plant and common on Blackheath, there was not 
much difficulty 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, light soil, and 
moss, which were kept moist, but not wet, having a free drainage. 
This 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 despatched 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. The full-fed larva may be 
briefly described, being almost without ornamentation and of an 
almost uniform warm stone-colour; it is about three-quarters of 
an inch long, moderately stout for an Acidalia, slightly thickest 
in the middle, and tapering gradually to the head, which is rather 
flat and small. The dorsal and subdorsal lines are obscurely 
indicated. When viewed through a glass of low power the dorsal 
line is seen to be composed of two fine parallel lines of faint grey; 
the subdorsal lines by a broken and indistinct row of grey dots, 
most distinct on the 10th, 11th, and 12th segments. The whole 
dorsal area is seen to be a series of fine transverse wrinkles, 
which, with a higher power, appear very like the ridges of 
corduroy, such as used for workmen’s trousers. ‘lhe spiracular 
line is closely marked by a produced and wrinkled skin-fold,
