ing day I met with thirteen more : on my route home I observed a couple near Brigh- 

 ton, one of which I captured, making in all fifty-one specimens, sixteen of which were 

 females : nearly all the specimens in splendid condition. They are not generally ea- 

 sily taken, as they mostly fly with considerable rapidity, and rarely settle except for a 

 moment ; the females are by far the easiest caught. It appeared to me strange that I 

 did not see or take a single specimen of C. Edusa. — Samuel Stevens ; 38, King St.,

Dear Sir, — I beg leave to inform you that a few specimens of Colias Hyale have 

 been taken within the last few days. The first specimen was taken on the 14th inst. ; 

 my brother also captured one on the 16th, since then five others have been taken ; the 

 last of them we have taken this afternoon, it is a female, being the only one taken as 

 yet. They were all, with the exception of two, taken in an extensive field of clover, 

 containing between four and five hundred acres, called " Heslington Field,'' about two 

 miles from York. They appeared to fly leisurely over the clover, some of them alight- 

 ing upon the flowers from which they were taken. The situation is rather high for 

 the Vale of York, and is a dry gravelly soil. I have no doubt they have been bred in 

 the field, as they were all in beautiful condition, and appear to have flown very little. 

 We took Col. Edusa in the same locality eight years ago, but C. Hyale has not, to my 

 knowledge, been taken in this neighbourhood since 1826. — Robert Cook; 30, Collier 

 Gate, York, August 2^, 1842. 



My dear Sir, — On Monday last, the 22nd of August, I captured at Chalk, near 

 Gravesend, ten specimens of Colias Hyale (seven males and three females) from the 

 flowers of Medicago sativa (lucerne). I did not observe it on the flowers of clover, or 

 any other plant, indeed it appeared to me to give an entire preference to the lucerne.

Dear Sir, — I have the pleasure to infonn you that I have captured two specimens 

 of Colias Hyale in this neighbourhood. The first, a small male, expanding only 1 inch 

 8 lines, on the 24th instant, at 11, A.M., in a very heavy clay pasture at Cockfield, in 

 the county of Sufi'olk, about three miles from Lavenham and seven from Bury St. Ed- 

 mund's ; it was on the wing when I first saw it, but settled twice on a flower of the 

 autumnal hawkbit (Apargia autumnalis). The other specimen, a very fine female, ex- 

 pands 2 inches 2 lines, was taken this morning (the 27th), about half a mile from 

 Lavenham on the Long Melford road ; it was very busy feeding on the hawkbit, and 

 visited several blossoms of it while I was screwing on my net, on one of which it re- 

 mained some time, within a yard of my feet : the soil here is also a heavy clay. I ac- 

 knowledge myself wholly indebted to you for this valuable addition to my cabinet, as, 

 from its resemblance on the wing, at a short distance, to a worn specimen of Pontia 

 Rapae, it would most likely, but for your note, have been unnoticed. — W. Gaze ; La- 

 venham, August 27, 1842. 



Second Note from Mr. Stevens. — Whilst walking after church yesterday, by 

 a clover field within a short distance of my own residence, I was not a little sur- 

 prised to see fly up a male specimen of the Col. Hyale ; and in another minute I 

 observed another, which proved to be the other sex. Not being at the time provided 

 with a net I did not attempt to catch them, but walked home and returned with the 

 necessary apparatus, and in a short time took three specimens. How many more I
