802 Insects. 



Note on the occurrence of Colias Edusa at Lympstone. Colias Edusa has made its 

 appearance again this year in this neighbourhood, but by no means so plentifully 

 as during the preceding season : I have seen five or six males and one female. Its 

 appearance seems to have been general, as my brothers have seen it at Teignmouth, 

 and letters from entomological friends mention its occurrence in other parts of the king- 

 dom. — Robert C. R. Jordan; Lympstone, October 14, 1844. 



Note on the capture of Colias Edusa in the Isle of Wight. In answer to your 

 inquiries respecting the appearance, this year, of Colias Edusa and C. Hyale, I send 

 you the accompanying list, which gives you the number captured, and seen additionally 

 by me; and the respective dates. With the view of being as accurate as circumstances 

 permitted, I did not hunt the neighbourhood round, but confined my researches to a 

 particular spot ; which spot, of between five and six acres in extent, consists of a 

 depression in the form of a horse-shoe, open to the south, and reaching down to the 

 sea-shore. From its sheltered situation, and from its abounding in wild flowers, it is the 

 favourite resort of C. Edusa, Cynthia Cardui, and Melitaea Cinxia in its season ; and 

 from its immediate vicinity (for the northern edge is only sixty yards from my house) 

 it was admirably suited to my purpose, as I could easily run out a dozen times in the 

 course of the day, net in hand, and capture all that would allow me to approach them. 

 This spot, then, I determined to make the field of my observations, and to forward to 

 you the result. I accordingly captured every individual that was not too agile for me, 

 every day, and carried them off to such a distance as I thought would effectually pre- 

 clude their return, thereby ensuring myself against the repeated enumeration of the 

 same individuals.

One of the five recorded as captured on the 20th September was the variety Helice 

 of Haworth's ' British Lepidoptera.' 



Such are the facts of the case; and the inference I draw is that C. Edusa, though 

 not so numerous as it was last year, has been more abundant than in any preceding 

 year since 1839. In that year I first saw this very beautiful insect, and captured 

 several specimens : in 1840 I saw only one or two: in 1841 a few were captured ; but 

 in 1842 not one was seen. Last year I think I might have taken more than the 

 number recorded above on the same spot. — Chas. A. Bury ; Bonchurch, Isle of Wight,

Note on the capture of Colias Edusa, near Chelmsford. Since my last communica- 

 tion respecting Colias Edusa, I have found the insect rather more plentifully in the 

 neighbourhood of Chelmsford, having taken four specimens, and seen several others. 

 1 1 has also occurred sparingly near Hitchin, in Hertfordshire, where I have myself
