avoid infection by separating and cleaning. One day, when the number of the 
worms was reduced to five, I found one diseased in close embrace with a healthy 
one ; I separated them at once, and the healthy one remained so, and spun July 
16th, and emerged subsequently." — (from Thos. Scott, Hamilton, Scotland.) 
" I had 12 eggs ; 8 worms hatched out early in May ; the eggs were kept in the 
quill in which they were sent, and kept in an envelope in a north room. About 
May 2nd the first larva hatched, and died, not being seen in time. The worms were fed 
on common oak, indoors ; the leaves were given three times a week, in a shallow 
box kept in the shade in an upper sitting-room, having a south-east aspect, 16 feet 
square ; doors and windows frequently open, as the weather was very warm. 
During an absence from home 3 worms died, and 2 escaped. I am afraid they were 
exposed to a hot sun. On my return 2 only were left ; they throve well, till one, 
after moulting, drank some water which was accidentally spilt : its head swelled 
up and became of a dirty brown colour, and it wasted away. The last worm I put 
on a branch of an oak inserted in a pot ; it soon began to spin, and emerged, a fine 
$ , August 30th," — (from Wm. Coti'On, Carogh Glebe House, Ireland.)

Scoria dsalha.ta; correction of an error. — In my communication respecting the 
habits of this species (p. 223), a mistake has occurred. Instead of " but fly 
reluctantly in the sunshine," should have been printed " but fly naturally in the 
sunshine." I particularly notice this as I had understood that the insect was generally 
disturbed from the long grass when walking amongst it ; and this I found was the case 
on dull days : but when I saw most of them it was in the forenoon, hot, and the sun 
shining brightly. They were then to be seen starting up on various parts of the 
hill-side, where there was nothing to disturb them ; so that it is most certainly a 
true day-flying insect. — W. R. Jeffrey, Safi"ron Walden, February 3rd, 1869. 
Early a^opearance of Tephrosia crepuscularia. — This species made its appearance 
in the wild state on February 5th, this year j but in ordinary seasons it does not 
occur before March ; the eai-liest specimen I have hitherto noted having been on 
February 15th, 1864, 
Last year I reared from the egg a good series of the dark smoky variety of 
this species, and should any of your readers wish for any, I shall be happy to give 
them away. — John T. D. Llewelyn, Ynisygerwn, Neath, February 8th, 1869. 
Late appearance of Eyhernia defoliaria. — In contrast with the precocity of P. 
pilosaria (see p. 224), If. defoliaria $ was found on the 10th inst., apparently fresh 
ii-om the puparium. — W. Herd, Perth, January ISi/i, 1869. 
Notes respecting fhe abundance of CoUas Hyale in 1868. — Having just read Mr. 
C. G. Barrett's interesting observations on the occurrence of C. Hyale in Britain, 
in the December number of the Entomologist's Monthly Magazine, I thought the 
following would be of use, as it occurred to me at a much later date than any men- 
tioned by Mr. Barrett.
