cilia alternately black and white. Forewing witli a large somewhat 

 square spot at the end of the cell, a little larger rhomboidal one below it 

 in the first median interspace, and a much smaller square one at the 

 middle of the second median interspace, three small conjoined round 

 subapical dots, of which the upper one is the largest, the middle one the 

 smallest, all translucent white ; an opaque dot touching the submedian 

 nervure in the middle of the submedian interspace. Hindwing with 

 three translucent white spots forming an equilateral triangle, of which 

 the two at the base are the largest and equal, and the apical one is a mere 

 dot. Underside, /o?'ez(7i/zgr with a broad costal streak occupying the upper 

 half of the discoidal cell and reaching to just beyond the middle of the 

 wing, and an apical patch, bright chrome-yellow, between which streak 

 and patch the ground-colour is castaneoas, the rest of the wings black ; 

 the translucent white spots as on the upperside, but with two additional 

 small black spots between the lowest of the subapical series and the spot 

 in the second median interspace. Hindwing with the basal half of the 

 wing chrome-yellow, the outer half castaneous ; a small round castane- 

 ous spot near the base of the wing, the three discal translucent spots as on 

 the upperside, but with two additional opaque round spots, one near the 

 costa at the inner edge of the castaneous portion of the wing, the other 

 in the middle of the submedian interspace, all five spots surrounded by 

 a fine black line ; there are traces of a series of blackish spots between 

 the veins near the margin. Head, thorax, and ahdometi black above, 

 beneath, legs, and pal2)i clirome-yellow. 



Very near to, but quite distinct from, Hesperia cephala, Hewitson,* 

 a fairly common Sikkim species, from which it differs in its larger size, 

 and in the following particulars : — the subapical series of spots on the 

 forewing has the middle spot the smallest and the upper one the largest, 

 while in JET. cephala the series is an increasing one ; in H. cephala the spot 

 below these is in the lower discoidal interspace, in H. cephaloides it is in 

 the second median interspace ; on the hindwing, in H. cephaloides there 

 are three small spots, in H". cephala there are two only, both large, the 

 outer one very large ; on the underside in R. cephala the costal yellow 

 streak extends uninterruptedly from the base to the apex, in H. cephaloides 

 it is interrupted by a large castaneous patch ; in H. cephala the hindwinoe 

 is entirely yellow, in H". cephaloides the basal half only is yellow, the 

 outer half being castaneous ; the spots too are very different and in 

 greater number and occupy different positions. 



I am indebted to Mr. B. Noble, the Curator of the Phayre 

 Museum, Rangoon, for the opportunity of describing this interesting 

 species, of which he has obtained two s[)ociniens. They were captured
