25 Aue. 1880.—The following letter, dated 
Coalburgh, W. Va., 22 Aug. 1880, from Mr. W: 
H: Edwards to Mr. S: H. Scudder was read: 
“ _.. If you like, you may say to the lepidopter- 
ists of the Association, when they meet, that I 
have raised a brood of Apatura flora from egg to 
imago, and the species is distinct from A. elyton. 
I described flora as a possible variety of clyton, 
you remember. I shall give a plate to flora. 
Also that I have raised a brood of Apatura alicia 
from egg to imago, and this is distinct from A. 
celtis, with which you and Riley and some other 
lepidopterists had united it as a variety. I will 
figure the larva of alicia also. 
“T have taken this summer a bi-formed Ly- 
caena neglecta, one side %, the other 9. 
“T had a Papilio ajax marcellus come from 
chrysalis perfect, except that there was no trace 
whatever of one hind wing. 
“ Thave two chrysalids of Limenitis disippus 
which have been on ice 30 days, and which should 
give imagos in 2 or 3 days. I hope to find these 
last changed in some direction by the cold. 
“JT have made some important observations on 
PSYCHE. 
L. disippus and its supposed varieties, but am not 
ready to publish them yet. The species is three 
brooded here — that I have ascertained,— and it 
makes its perch not by means of its excrement, 
but with bits of leaf chewed up in the mouth. The 
object of the packet of bits of leaf is not yet 
certain. 
“TT. L. Mead has been in Newfoundland the 
last six weeks, and sent me specimens of Coe- 
nonympha inornata Edw., taken there by him ;— 
a butterfly that I do not think has been re 
ported as living within a thousand miles of that 
island. 
“From Florida I have received examples of 
Pieris ilaire, C. agarithe, and a new Pamphila, size 
of P. dion, which I call P. byssus; also the 
sphinges Oenosanda noctuiformis, and Anceryx 
scyzon, not before attributed to North America. 
“ Hope you will have a good time, and wish I 
could be of the party.” 
Mr. A: R. Grote said that Mr. Edwards had 
also received Didasys belae and Dahana atripen- 
nis, two rare zygaenidae, from Florida. 
30 Ave. 1880.—The following letter, dated 
Carbondale, Ill., 18 Aug. 1880, from Prof. Cyrus 
Thomas to Mr. S: H. Scudder, was read: “... My 
investigations, during the past and present year, 
in reference to the migrations of Caloptenus spre- 
tus, have brought to light facts which indicate 
that, after all, the opinion you and I formerly 
held in regard to their movements is not so far 
wrong as has been supposed. While it is proba- 
ble that in some instances swarms sweep down 
from British America and Montana in a single 
season to Nebraska and Kansas, a careful study 
of their history in Dakota indicates that they 
usually move by successive waves (generations). 
This theory is also the only one that will conform 
to the meteorological conditions in 1866, 1874, 
and 1876. I am also of the opinion now that 
Minnesota may ultimately be freed from them, 
if the Coteau of the Prairies can be clothed with 
trees, and the lakes are preserved so that the 
water surface remains the same asitisnow. I 
cannot give my reasons for this opinion in a let- 
ter, but have written them out rather briefly for 
Governor Pillsbury of Minnesota. They will also 
be given in our Third Report... .”
