ON THE EARLIER STAGES OF COLIAS EDUSA, 
By F. W. Fronaws, F.E.S. 
On the 7th of June last I had the pleasure of receiving two 
live females of C. edusa, which Mr. S. G. C. Russell had taken in 
the Polegate district fhe previous day. He very kindly presented 
both to me, knowing I was anxious to rear this species from the 
ego, A few notes thereon may be of interest, as we are now in 
the height of an edusa season, after a lapse of fifteen years. 
Upon becoming possessor of these lively females, I imme- 
diately went in search of a couple of suitable plants of clover for 
their reception, and in less than two hundred yards from my 
house I hit upon the very plants, which I soon had potted ready 
for them; curiously enough the plants I dug up had already been 
visited by C. edusa, as I found an egg upon each, which had, from 
their appearance, been deposited a day or two before, being then 
of lilac colour, and the following day they became light red. 
These two eggs I kept carefully under observation, and upon 
these further notes will be made later on. 
I placed a female C. edusa on each plant, and enclosed them 
under a gauze covering. Upon the gauze I spread a little sugar 
and water, and placed them in the sun. At mid-day I found one 
female had deposited a few eggs, and towards evening I was 
pleased to see several more, about two dozen, had been laid by 
the same female; the other had also deposited a few ova. The 
female first referred to died the following day ; the other appeared 
also to be in a dying condition, so I removed her from the plant, 
uncoiled her tongue and immersed it in treacle, which she im- 
mediately began to unbibe, and continued for fifteen or twenty 
minutes. Thinking she had taken enough I again put her upon 
the plant, and found her quite revived; she quickly deposited 
more eggs. The following day I treated her the same, and she 
recommenced laying and spent herself. On the 11th I was able 
to count at least three dozen eggs laid by her; in all, I counted
