aberrant in having in the onter groove of the proximal joints as vrell as on the dorsal 

 snrface of the not-scaled apical joints a great nnmber of erect fine hairs ; in this 

 character T. chri/xoyone differs obviously not only from the other species of the 

 genns, but from all other Safyi-inaf, so far as I know. The apex of the last joint 

 has in many Satyrinae a rather large nnmber of long bristles, while in other species 

 these bristles are short and few in number. 



(2) The second type is represented by Sinchuhi. (f. 57). The grooves are liere 

 reduced to somewhat rounded dimples which stand widely apart. The median 

 carina, though feeble, is nevertheless developed. The fine sense-hairs are restricted 

 to the grooves. Two short bristles near the inner edges of the patch of sense-hairs 

 corres})ond to the ventro-basal pair of bristles of the first type. The lateral pair of 

 bristles is well developed. 



(3) The third type is met with in Ipthima-asterope (f. .58). Here the grooves 

 are still more restricted than in the second type, and stand near the apex of the 

 joint; they bear fine sense-hairs, while the rest of the ventral surface i.s densely beset 

 with setiferous punctures. Tiie lateral pair of bristles is subapical ; the ventro-basal 

 pair is obsolete. The median carina is not developed. Other species of Tpthimn 

 have the antennae of the first type. 



(4) The fourth and most simplified t3-pe occurs in Triplii/sa {rlnlmii, f. 59), 

 peculiar insects found in Central Asia. The grooves as well as the carinae are 

 absent: but the fine sense-hairs, which are few in number, stand in two patches 

 corresponding in position to the grooves of other Nymphalid Butterflies. At the 

 inner border of each patch a short bristle is visible, which is homologous to the 

 ventro-basal pair of other Satijrinae ; the lateral pair is also developed, but 

 the bristles are short. 



ri. BRASSOLINAE. 



The antenna is either scaled dorsally from the base to the apex {Nerope), or 

 is not scaled except at base {('aliyo, Brassolis). The three ventral carinae are de- 

 velojied, and in all species finely but obviously serrate. In respect to the structure 

 of the joints the two principal types are represented by Brassolis and Caliqn. 



In Brassolis (f. 61) the joints have the three carinae strongly developed on the 

 stalk; the grooves between them are deep for their entire length (the apical edge 

 only of the joint not being impressed); on the club, however, the carinae are very 

 feebly raised, and the impressions between them are so shallow that one can 

 scarcely speak of grooves. The grooves on the stalk bear only a very few sense- 

 hairs, situated near the base of the joint. Of the ventro-basal pair of sense-bristles 

 only one is visil)le and that is more obvious only on the joints of the club, while 

 the lateral pair of bristles of other Nymphalids is also in Brassolis plainly visible. 

 The joints bear dorso-laterally very few setiferous punctures, and are of a very 

 smooth appearance. 



In Caligo (f 02) the carinae are as high on the joints of the club as on those of 

 the stalk, and the grooves between thom are deep both on club and stalk. As the 

 grooves extend to the very edges of the joints, and the carinae are high throughont 

 their length, the apical margin of each joint is deeply bisinuate. The grooves bear 

 sense-hairs from the base to the apex, but the hairs are more densely set at the base 

 of the joint. Dorso-laterally the joints are rough with setiferous j)nnctures. A pair 

 of short ventro-basal bristles, and a lateral pair, situated between base and middle on 

 the joints of the stalk, are present.
