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, HamiUon, 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 veiy 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

Scoria dealhata; 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^ppearamce of Tephrosia cr^puscularia. — This species made its appearance 

 in the wild state on February 5th, this year ; but in ordinary seasons it does not 

 occur before March ; the earliest 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 Sth, 1869. 



Late apTpea/ra/nce of Hybemia defoliaria. — In contrast with the precocity of P. 

 pilosaria (see p. 224), H. defoliaria (J was found on the 10th inst., apparently fresh 

 from the puparium.— W, Heed, Perth, January 18</i, 1869. 



Hotes respecting the 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.
