/'. MORPHINAE. 



Ill most genera the antenuae are bare of ncnles, while in some (Disrop/wia) the 

 dorsal surface, with the exception of the chili or part of it, is covered with scaling. 

 Ventrally there are three carinae, which are not serrate as in BrassoUnae; the 

 carinae are his:h on stalk and clnb, but in some forms (some species of Tenaris) they 

 are not well marked on the distal joints. The grooves between tliem extend from 

 the base to the apex of the joint. The fine sense-hairs are either nearly eqnally dis- 

 tribnted over the groove (f. 63, Tcmiiig bioculntus), or are rather sparse, forming 

 generally two patches, a basal and a snbapical one, in each groove (f. 64, Discopkora). 

 The bristles are mostly rather conspicuous; in Tenvris, Hi/anlis, and allies they are 

 mostly very long. Besides the ventro-basal pair there is sometimes a second pair 

 in the grooves of the stalk, standing in or beyond the middle of the joint. The 

 lateral bristles of the stalk are snbbasal, on the last joints of the club they are more 

 median, and in certain Tenaris even apical. Sides of antenna coarsely pnnctnred. 



i. XYMPHALINAE. 



This group, containing the greater number of species of Nvmphalid Butterflies, 

 offers great diversity in minor points. The iintennae can be grouped according to 

 the development of the scaling as follows : (1) Scaling dense; tlie ventral surface 

 of the club, and, besides, the dorsal surface of the last two joints, not scaled {Cher- 

 sonesia, Phi/ciode.H). (2) Scaling as extended as before, but the distal joints of the 

 stalk have each a bare basal space, reminding one of the not-scaled spaces found 

 in certain Lycaenidae, Eri/cinidae, and Pieridar (f. 05, Araschnia). (3) Scaling re- 

 stricted to the dorsal surface ; last two or more joints (at the highest about half the 

 clnb) not scaled dorsally. Here belongs the bulk of tlie subfamily. (4) Scaling 

 absent (the most basal joints excepted): a rare type (Prot/ioi'}. 



The scales are generally rather broad, two- or three-toothed, but in some cases 

 (Ckaraxes) they are short and narrow. 



There are always three carinae marked on the ventral side, varying in height 

 considerably in the different forma of Xymphalinac. In Euresia, which has only 

 the ventral side of the club not scaled, the carinae are feebly developed. The 

 grooves between the carinae extend from the base to the apex of the joint in those 

 forms where the ventral side of the joint has no scaling, but are on the club some- 

 times very shallow and often broader than long. The tine sense-hairs are either 

 evenly distributed over the groove (f. 66, Pfirtkenos ; Dione), or are gathered together 

 in sm elongate or rounded patch ( 17; wc.s-.w, f. 67). Normally there are jiresent a 

 ventro-basal j)air of liristles, as well as a lat<'ral pair which is subbasal or median, 

 but on the club sometimes subapical or apical {Romalaeosoma). The sides of the 

 antennae are densely jmncturcd. 



k. NEOTROPINAE. 



The squamiform structure of the skeleton of the joints is in tiiis group generally 

 finer than in most other Si/mphfilidae. In the shape of the joints there is a rather 

 great diversity among the Xcofro/ihirif. 



The scales are rather loose and fall off easily. The scaling is restricted to the 

 dorsal surface; it reaches in many forms to the middle of the clnb, but in others 

 it is confined to the basal half of the stalk.
