and in the Gayoe territory. The males come to roads and to sandy 

 river banks ; the females are very rare, and Dr. Martin obtained three 

 only. 



613. Papilio (Paranticopsis) megarus, Westwood. 



Hagen. Very rare in our area, perhaps less scarce on the western 

 boundary, four specimens only obtained from January to March at 

 Kepras and Bohorok. Dr. Hagen obtained a single example from the 

 outer hills. 



614. Leptocircus curius, Fabricius. 



Grose Smith. Snellen. Hagen. Staudinger. Distant. 



615. Leptocircus meges, Zinken-Sommer. 



Hagen. Staudinger as virescens. Both species of Leptocircus occur 

 throughout the year in the plains and on the outer hills ; they are fond 

 of running water, and fly very low over open grassy places on river 

 banks ; they often settle on wet sand, but never on the grass. When 

 flying they make constantly a strange vibrating motion with the hind- 

 wings, which adds to their strong likeness to dragonflies. The females 

 are rare. 



Family HESPERIID^. 



In the family Hesperiidee we have followed the order given in 

 Captain E. T. Watson's paper in the Journal of the Bombay Natui-al 

 History Society, vol. ix, p. 411 (1895), entitled "A key to the Asiatic 

 Genera of the JLesperiidoe^ which considerably changes the sequence 

 of the genera in Captain Watson's previous paper in the Proceedings of 

 the Zoological Society of London, 1893, p. 3, " A proposed Classifica- 

 tion of the Hesperiidee, with a Revision of the Genera." 



616. Orthoph(etus phan^jus, Hewitson. 



Grose Smith as plianeus [sic]. Occurs rarely in forest near Selesseh 

 and on the outer hills, only two male specimens obtained, one in April, 

 the other in August. 



617. Charmion ficdlnea, Hewitson. 



C. ficulnea, de Niceville, Journ. A. S. B., vol. Ixiii, pt. 2, p. 49, n. 1 (1S94). 



Grose Smith. On the outer hills and near Bekantschan throughout 

 the year not very commonly.
