" Perhaps the commonest butterfly met with singly — here, there, 

 and everywhere." (M. G.)

All the specimens were " taken perching on a straw protruding 

 from the thatch of the house-roof (three of them) on a bright hot 

 day at noon." (R. C.)

On the upper surface this species exactly resembles P. ferox 

 (Wallgr.), but is slightly larger: on the under surface it differs in 

 the elbowed creamy subapical transverse stripe on the primaries 

 (which is straight m P. ferox) and in the less regular arched bands 

 on the secondaries, the central white band being broader and 

 abruptly drawn back at first median branch so as to impinge upon 

 the olive-brownish band behind it, and from that point narrowed 

 to half its width, the olive-brownish discal band being abruptly 

 widened into a sort of heel to fill the area thus left vacant ; the 

 submarginal white stripe is broken up into unequal spots, some of 

 which are almost obliterated. In addition to these important 

 differences, the white spots on both surfaces of the primaries are 

 much purer than in P. ferox. Expanse of wings 31 millim.

I hope Mr. Crawshay will send more examples of this pretty 

 little Skipper-butterfly.

The specimens forwarded by Mr. Crawshay have two defined 

 divergent white stripes on the under surface of the secondaries ; 

 but a male sent by Mr. Marshall shows a second (though less well- 

 defined) stripe, through the intern o-median area; thus forming a 

 transitional grade. Mr. Crawshay's male shows very little white 

 on the abdominal border of the secondaries, and has the discal 

 yellow spots characteristic of the female well-marked. In this 

 species the transparent spots which cross the middle of the pri- 

 maries vary from four to six in number ; both Mr. Crawshay's
