A KEVISION OP THE OEIENTAL HESPERIID^E. 225 



pointed, term en straight, oblique; vein 5 nearer 4 than 6, vein 2 from the basal 

 fourth of lower edge of the cell. Upperside brown, with pale spots in cells 2, 3, 

 6, and 7, one or two near the apex of the cell on the fore wing, and sometimes one in 

 cells 4 and 5 ; the disc of the hind wing is more or less extensively yellow. Epiphysis 

 present ; hind tibiae fringed and bearing two pairs of spurs. 



There is some difference in the comparative length of the cell of the hind wing in the 

 different species ; it is longer in P. tessellata, Hew., than in the others. In P. callineura, 

 Feld., and its allies, the base of cell 5 in the fore wing is about one and a half times as 

 long as that of cell 4 ; in P. tessellata, noemi, &c., the bases of cells 4 and 5 in the fore 

 wing are subequal in length. 



The species known to us we distinguish as follows : — 



Males. 



1 (16). A hyaline spot in cell 4 of the fore wing. 



2 (11). Hind wing below with pale purple or bluish-white spots. 



2a {2b). Termen of the hind wing broadly and decreasingly yellow from the 



dorsum as far as vein 3 vermiculata, Hew. 



2b {2a). Termen of the hind wing not as above. 



3 (8). Shaft of antennae entirely pale beneath. 



4 (7) . Hyaline spots in cell of fore wing remote. Tegumen simple. 



5 (6). Hind wing below : veins rather broadly vermilion-red. Lower lobe 



of clasp produced into two strong teeth at apes callineura, Feld. 



6 (5). Hind wing below: veins yellow. Lower lobe of clasp produced at 



the apex into one strong tooth, the apical half of which is 



spiniform latoia, Hew. 



7 (4). Hyaline spots in cell of fore wing confluent. Tegumen with a short 



tooth on each side at the base margherita, Dohy. 



8 (3). Shaft of antennae entirely blackish, club pale beneath. 



9 (10). Fore wing above: basal three-fifths of cell 1 a filled up with yellow, 



the yellow colour spreading to the dorsum at the base. Hind 

 wing above : cell entirely pale, the disc of the wing yellow from 

 the dorsum as far as vein 6, the dorsum broadly yellow as far as 

 the termen helena, But], 



10 (9). Fore wing above: an elongate triangular yellow spot in the basal 



half of cell 1 a, its apex reaching the base of the wing on vein 1 a. 

 Hind wing above : upper half of the cell blackish, the yellow 

 discal patch not reaching the dorsum, the latter dark brown 

 with a yellow streak fruhstorferi, Mab. 



11 (2). No purple spots on hind wing below. 



12 (13) . Fore wing with the basal two-thirds of cell 2 hyaline. Hind wing 



below red-yellow, with irregular black dashes ; a broad black line 



in the basal two-thirds of cell 7 aurantiaca, n. sp.
