Female Pupce of Bombijx Qnercus attractive to Males. — 

 The latter end of last month I had two pupoe of Boinbyx 

 Quercus, which I placed near an open window. I was very 

 surprised a day or two afterwards to see a male oak eggar 

 hovering over the pupa-case. I have often caught them 

 with the perfect insect, but never knew they were attracted by 

 the pupa. The two pupaj have since emerged, and are two 

 very fine female specimens. Can you give me any enlighten- 

 ment on the case? — Charles G. Vicary ; Knowles, Newton

Eiithemonia russula reared from the Egg. — At the latter 

 end of June and beginning of July I captured four female 

 Euthemonia russula. They produced me about sixty eggs, 

 which were hatched in the third week in July. I fed the 

 larvae on dandelion and narrow-leaved plantain ; the favourite 

 being dandelion. About the beginning of August, observing 

 that sixteen or eighteen were progressing much faster than 

 the rest, I removed them to a larger cage, in which they 

 remained until the beginning of September, and retired from 

 sight. On the 15th of that month, seeing no sign of them, I 

 thought to clear the cage of any refuse they had left, and was 

 surprised to see six perfect insects, all females. Since then 

 they have been appearing daily; and I have now sixteen, 

 twelve being females and four males; one female I am sorry 

 to say is a cripple. I have not forced them in any way. The 

 larvae, when small, were kept in a tumbler covered with 

 muslin : as they increased they were removed to a glass 

 cylinder; and the eighteen were removed to a larger cage, 

 and kept in the coolest place I could think of to be handy, — 

 that was the grate in the bed-room, — never exposed to the 

 sun, but subject to the draught of the chimney, and the windows 

 of the room being open day and night. The rest of the larvae, 

 about forty, are lively and apparently healthy, and varying in 

 length from about half an inch to an inch : indeed, so active 

 and peculiar is their movement that I am highly amused and 

 fully employed (when changing their food) to prevent their 

 escaping from a sheet of newspaper. Their invariable prac- 

 tice is to roll in a ring ; when after a time they will uncurl, 

 and "run-a-muck" with an incredible wriggle across the
