referred to Cyaniris of Dalman ; Scudderii and Comyntas respec- 
tively to the Hiibnerian genera of Lycsides and Everes; for 
Pembina the new genus of Glaucopsyche is established having 
Iygdamus for its type. The genus Lycena, after various limita- 
tions and some misapplications, and the last restriction in 1832 
by Swainson to species of the European Phileas type, is retained 
for Americana and Epixanthe, leaving Thoe for the genus Chryso- 
phanus under the specific name of Hyllus by which it was first 
described by Cramer. 
The family of PAPILIONIDES comprises the Danar and 
Equires of Linnæus, and the Pieride of later systematists. In 
it, fourteen genera are enumerated in the present paper. 
The reference of Eubule to Catopsila of Hübner instead of 
Callidryas Boisd., is in accordance with Kirby’s recent arrange- 
ment. Coliasisretained for Philodice, Eurytheme and Keewaydin ; 
rape and oleracea are removed to the genus Ganoris of Dalman ; 
protodice and vernalis to Synchle of Hübner. 
The dismemberment of Papilio reaches its greatest possible 
extent in the assignment of our five species to as many genera, 
established by Scopoli, Dalman and Hübner. Under their new 
homenclatare they present themselves as Laertias Philenor, 
terourus Troilus, Euphoades Glaucus, Iphiclides Ajax and Ama- 
Tyssus Polywenes (= Asterias). 
So long ago as in 1859, it was announced that Mr. Scudder was 
engaged upon a monograph of our Hesperide. The result of his 
study in this direction is given in part, in the systematic arrange- 
ment now before us of the heterogeneous material which had been 
Previously referred to the genera Eudamus, Nisoniades, Pamphila 
"a Hesperia— the latter serving as a convenient receptacle for 
Whatever species might not properly be located elsewhere. For 
tie order evoked from so great confusion, we owe the author a 
_ debt of gratitude. 
Under the Linnean name of URBICOLÆ, our American Hes- 
Peride: (including all the United States species together with a
