the termination of the third median norvule ; a streak of chrome-yellow 

 placed in the submedian interspace springs from the base of the wing 

 and runs into the yellow anal area ; the abdominal margin and cilia 

 chrome-yellow. Underside, forewing fuscous ; the costa, discoidal cell, 

 apex and outer margin decreasingly to the anal angle streaked with 

 chrome-yellow ; the five semi-trausparent spots as above ; a broad, short, 

 chrome-yellow streak towards the base of the wing in the submedian 

 interspace ; a pale blue slightly iridescent sti*eak just beyond the end 

 of the cell in the upper discoidal interspace. Hindwing chrome-yellow, 

 with the following black markings : — The costa at the base . of the 

 wing, two subcostal streaks from the base to the apex of the wing, 

 the posterior of these interrupted towards its end ; a streak in the 

 subcostal interspace also outwardly interrupted ; a streak in the cell ; 

 a very broad one twice interrupted in the submedian interspace ; 

 a rather obscure streak in the internal interspace, extending from 

 the base to a little beyond the middle of the wing ; three small 

 spots on the disc between the veins : also with the following pale blue 

 slightly iridescent elongated spots : — Two in the discoidal cell, and a 

 series of eight others extending right round its outer end. Antennce 

 black, club prominently chrome-yellow above, the apex black. Palpi 

 black above, yellow beneath. Thorax above black clothed with long 

 yellow hairs. Abdomen black, ringed with yellow. Legs yellow. 



The nearest ally to P. vermiculata appears to be the " Hesperia " 

 flavescens of Felder (Reise Novara, Lep., vol. iii, p. 517, n. 905, pi. Ixxii, 

 figs. 7, male) 8, 9, female, 1867), from Celebes, from the female sex of 

 which the present species differs in several particulars on the upperside, 

 and conspicuously on the underside, in the presence of the pale blue 

 slightly iridescent spots, these being apparently entirely absent in 

 P. flavescens. 



This very lovely species is described fi-om an unique example in 

 Dr. Martin's collection taken at Bekantschan, at the foot of the Battak 

 Mountains, in N.-E. Sumatra, in July, 1893. Mr. Hewitson originally 

 obtained it from Sumatra also.
