down for hop-poles. These clearings abounded with Crataegi, Sibylla, 
W. album, and other species. The soil consists of a damp, tenacious 
clay, so as apparently to be quite unlit for the transformation of larva 
in it. This may account for the fact of my never having found any 
pupae in the neighbourhood of Chatham, although I tried to be persever¬ 
ing in the search for them. 
I shall now proceed to enumerate the species that I met with, 
omitting the very common species which occur everywhere. 
Rhopaloceea. 
Papilio machaon. —A specimen was taken by Mr. Channy on the top of a 
chalk hill. Towards the close of the summer I saw it, and it was 
in line condition. How could it have strayed so far from its 
haunts ? 
Gonepteryx rhamni. —Abundant. 
Colias edusa .—I had the pleasure of seeing, but did not capture, this 
insect. 
Colias hyale. —I took a fine pair in a clover field on the side of a preci¬ 
pitous chalk hill. 
Aporia cratcegi. —This fine insect is pretty abundant in the woods in the 
beginning of June, but from the strength and rapidity of their flight, 
they are difiicult to capture. (I took about twenty.) 
Leucophasia sinapis. —This insect I did not take myself, but have seen 
specimens captured in the neighbourhood. 
Arge galathea. —Very abundant, but local. 
Hippa/rchia semele. —One or two specimens in the same field as C. hyale. 
Limenitis Sibylla. —This beautiful species occurred in considerable 
numbers along the edges of a clearing, which was almost the only 
place I met with them. It is really delightful to watch their grace¬ 
ful easy flight, as they float about on the bright sunshine of a 
summer’s day. Hoes the larva ever feed on the sallow, as nearly 
all the specimens I captured were at rest on stunted bushes of that 
tree, and I could only find one small plant of honeysuckle in the 
immediate neighbourhood ? 
Apatura iris. —This magnificent species occurred in large numbers on the 
top of a hill, wooded with lofty oaks. I only succeeded in captur¬ 
ing three, as I did not possess an “ Emperor” net, and was not aware 
at the time of the efficacy of putrid animal remains as a bait for his 
majesty. To obtain the specimen I did, I had to extemporize a net 
by fastening the one I carried in my hand to the end of a long sap¬ 
ling. This, however, formed a very unwieldy weapon, as the result 
showed. 
Cynthia cardui. —Occurs generally. I did not meet with it. 
Vanessa polychloros. —Abundant; but very hard to capture. I met with 
hybernating specimens in the spring, much more frequently, however, 
than the insect fresh from the pupa, in the autumn.
