as far caiidad as the second abdominal segment. The metathorax al- 

 ways has a median elevation, which sometimes forms a prominent 

 angle. The circular ridge surrounding the anal opening is not strongly 

 elevated but the tubercles are prominent on each side of the genital 

 opening on the ninth segment. The genera of this subfamily may be 

 separated by the following table : 



a. Cremaster broader than long, with hooked setae present on the ventral 

 surface ; genital opening never with a tubercle on each side. 



Cissia Doubleday. 

 aa. Cremaster longer than broad, the hooks always inserted at the dis- 

 tal end, never on the ventral surface ; genital opening always with 

 a distinct tubercle on each side, 

 b. Mesothoracic elevation rounded ; cremaster concave at tip with 

 the hooked setae inserted in the hollow; body surface with fine 



indeterminate striations Cercyonis Speyer. 



bb. Mesothoracic elevation with a distinct angle ; cremaster not con- 

 cave at tip ; body surface smooth Saiyrodes Scudder. 



The following species were examined : 

 Cissia eurytus Fabricius 

 Cercyonis alope Fabricius 

 Satyrodes canthus Linnaeus 



Subfamily Ocneinae 



The genus Oeneis has none of the distinguishing characters of the 

 subfamily Satyrina^ and therefore is not here included with the mem- 

 bers of that group. The body has the general shape of a lycaenid, and 

 the segments seem as devoid of motion (Fig. 80). In other respects 

 it is a typical nymphalid. The antennae do not quite reach the caudal 

 margin of the wings, and overlie the maxillae at their distal end, so 

 that the antennae are adjacent on the meson. Their proximal ends 

 are very near the meson on the dorsal surface of the head. There is 

 no distinct ridge surrounding the anal opening, nor are any tubercles 

 present caudad of the genital openings. There is no cremaster, nor 

 hooked setae at the caudal end of the body. 



Only one species was examined : 

 Oeneis seniidca Say. 



Specialized pupae without pilifers 



This division includes the remaining superfamilies of Lepidoptera. 

 The seventh abdominal segment is fixed in both sexes in all the fami- 

 lies except the Epermeniidae, in which this segment is fixed in the
