THE CANADIAN NATURALIST. 
secure as many specimens as you please. It is a wide- spread 
species^ extending from Newfoundland to the Gulf of Mexico, 
and perhaps farther : in the State of Alabama it is common 
Another species, the Black Swallowtail f Papilio Asterius ), is 
likewise found in Newfoundland and in the Southern States, 
in both of which I have found it numerous, and I have seen 
it mentioned in lists of New England insects, yet I have not 
met with it in this province. I should suppose, however, 
that it is a native, but probably, as in Newfoundland, only 
appears plentifully in particular seasons. 
C — The other butterflies were the Clouded Sulphur 
( Colzas Philodice ), and the Black Skipper ( Thymele 
Brizo ? J. 
JP. — The former is very abundant through the summer, 
and continues till late in autumn : it is a pretty butterfly ; 
the female, especially : her yellow-spotted black border, and 
pink fringe, is much more becoming than the plain black 
of the male. The extent of the black margin on the poste- 
rior wings differs much in individuals, and there is more vari- 
ation in size in this species tha.n, I think, in any that I am 
acquainted with. I once saw an individual which was so 
pale as to be nearly white : whether it was a distinct species, 
I don't know. The skipper is not numerous ; three or four 
specimens being as many as I have usually seen in a season. 
Its form and colour are not at all pleasing ; it has the habit 
of all the Hesperi(Ey of jumping up and down in its flight 
over the herbage ; whence these butterflies have derived the 
name of skippers. What other insects have you observed ? 
C. — I went out a day or two ago bush-beating among 
the willows, but the leaves were too young and small to 
afford me much success. I shook off a black Sawfly ( Ten- 
thredo), two green Waterflies (Perla Ct/dippe?), two Ci- 
mices ( Pentatoma P J, several Chrysomelidce, with soft 
horn-coloured elytra ( Crioceris P J, and another very
