SYNOPSIS or THE GENERA* 



Section I. RHOPALOCERA.

 least the primaries, elevated in repose; iio hr\st\e or freimlum ; 

 no stemmata or simple eyes — flight diurnal. 



Fam. I. Papiliouiflae. 



Larva with two retractile tentacles on first segment. Eyes promi- 

 nent ; palpi short ; six feet adapted for walking ; wings wide, nerves 

 distinct, abdominal edge of the secondaries concave, discoidal cell 

 in both wings closed, hooks of the tarsi simple, abdomen free. 



A. Club of antennae arcuate ; 



Wings wide, secondaries with long tails or lobed. Papilio. 



B. Club straight ; 



Primaries transparent at the summit, two black ocelli in the 

 discoidal cellule, abdomen of the female with a corneous

* [The present synopsis is believed to be approximately correct and 

 generally agrees with the body of the book as far as the Rhopalocera are 

 concerned, but in the Heterocera the conformity is not so rigid, owing to 

 the indistinctness of some of our new American genera and an indisjiosi- 

 tion to create new families in which to place them. Further investigation 

 will be required to determine their proper place in the system. The sy- 

 nopsis, however, gives a tolerably fair exhibit of our Lepidopteral Fauna, 

 exclusive of the Noctuidx proper, which may, however, hereafter be some- 

 what improved. 



The Genus Pimela, p. 129, belongs to Bombjjcidu', inadvertently placed 

 where it now stands. — J. G. M.]
