SYNOPSIS OF NORTH AMERICAN BUTTERFLIES. 
51 
NOTES. 
In preparing the Synopsis manuscript names have been omitted and names 
of species that have been erroneously credited to the North American fauna. As 
respects the genera, I have aimed at giving those with which our lepidopterists have 
now for several years been familiar. An exception was necessary in case of the 
Hesperidse, a family hitherto greatly neglected and in which material had accumu- 
lated to a vast extent, rendering revision imperative. Mr. Scudder has for some 
years been engaged in this work, and his recently published results I have large- 
ly followed. 
Pages 1 to 6, 10, 11 and 19, have been reprinted with corrections since their 
original issue. 
Papilio Aliaska. — I have substituted this name for Machaon , considering the 
American insect to be sufficiently distinct from the European to entitle it to a spe- 
cific name, as pointed out by Mr. Scudder. 
Papilio Calverleyii. — The individual described by Mr. Grote was a male 
and seemed to be a variety of Asterias, rather because of its similarity of shape, 
and from its having been taken where Asterias was a common species, and from 
the fact that in so well worked a district as Western Long Island nothing ap- 
proaching it had before been seen. It was regarded as one of those extreme vari- 
ations occasionally seen among the butterflies. I have examined the fine female 
taken by Mr. Mead, high up the St. John’s River, Florida, and certainly cannot 
undertake to pronounce it a variety. It is as distinct in all respects except in shape 
from Asterias as is Turnus. If it is a mere variety, no better illustration of the 
origin of a species is needed. It is not improbable that this butterfly is common 
enough in southern Florida, which is a terra incognita to lepidopterists. That an 
individual should have been found on Long Island is less remarkable when we 
consider how many strictly southern insects and birds have been found there 
while unknown upon the adjoining main land. 
Thecla Liparops. — By reference to the original unpublished drawings of 
Abbot, in the British Museum, Mr. Scudder has ascertained that this species was 
intended by Boisduval and Leconte to represent the butterfly described by Harris 
as Strigosa. How utterly unlike the latter as delineated in this Volume a glance 
will show.- On comparing the description in Boisduval and Leconte with the 
insect, and then with fheir plate, it is evident that the description was not drawn 
from the former, but from the 'plate, which is so wretched an attempt at copying
