96 HAUSTELLATA. — LKPIDOPTERA. 



A very local species, and hitherto supposed to be peculiar to 

 Scotland, but it has lately been taken in the north of England ; it 

 frequents meadows and grassy places, like its congeners, appearing 

 first about the middle of June, and secondly in August, and is most 

 abundant at the foot of Arthur's-seat, near Edinburgh. " Salisbury- 

 craigs, King's-park, and near Duddingstone-loch, Pentland-hills, 

 Lord Roseberry's park near Queensferry and Rosslyn castle, 

 Scotland." — J. C. Dale, Esq. " Jardine-hall, Dinwoodie-green 

 near Lockerby, Dumfrieshire." — Si?- W. Jardine, Bart. " Seaham- 

 dean near Sunderland." — W. C. Heivitson, Esq. " A few specimens 

 taken on the coast of Durham near Sunderland." — G. Wailes, Esq. 

 " I once observed it on Dartmoor, 23d August, 1823." — Dr. Leach. 



Family lV.--HESPERIIDiE, Szvamson. 



AntcnncB with a distinct fusiform club, generally furnished at its extremity with 

 a hook: abdomen robust: legs in both sexes perfect, all formed for walking ; 

 hinder tihicc with two pair of spurs, one pair placed at the apex, the other 

 towards the middle, as in the Crepuscularia and Nocturna Latr. : da ws minute, 

 bifid : posterior iv{?igs with a groove to receive the abdomen. Larva pubes- 

 cent or naked, fusiform, with a large head : pupa short, smooth, enclosed in 

 a web, with a slender transverse thread. 



The Hesperiidse are distinguished from the other Diurna by 

 having two pairs of spurs to their posterior tibise, and a hook at 

 the extremity of their antennae. They are small insects, but their 

 body is very robust, and they fly with rapidity and strength, fre- 

 quently resting on leaves and branches, and elevating their posterior 

 wings above during their repose, the anterior being kept horizon- 

 tally displayed. Their flight is very short, and performed with 

 frequent jerks; whence they have obtained the appellation of Skip- 

 pers. The prevalent colour is brown or dusky, with pale whitish, 

 yellow, or transparent spots.

 thus discriminated :

* Pa. Bucephalus apparently belongs to a cU fFer en t genus ; but my objection 

 to multiply genera without powerful reasons has induced me to consider it as 

 belonging to a section of the genus Pamphila.
