and in the Gayoe territory. The males come to roads and to sandy 
river hanks; 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. Scaudinger. Distant. 
615. Leptocircus meges, Zinken-Sommer. 
Hagen. Staudiuger 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 HESPERIHLE. 
In the family Hesperiidse we have followed the order given in 
Captain E. Y. Watson’s paper in the Journal of the Bombay Natural 
Historv Society, vol. ix, p. 411 (1895), entitled “A key to the Asiatic 
Genera of the PLesperiidaefl 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 j Kesperiidse, with a Revision of the Genera.” 
616. Orthoptketus phan^ius, Hewitson. 
Grose Smith as phaneus [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 ficglnea, Hewitson. 
C. ficulnea, de Niceville, Journ. A. S. B., vol. lxiii, pt. 2, p. 49, n. 1 (1894).

the year not very commonly.
