Genus XX. — Pamphila, Fubriclns. 



Palpi short, compressed, very densely clothed with scales and short rigid hairs, 

 or expanded and densely covered with scales only, the tciTninal joint slightly 

 projecting beyond the hirsuties: antenna: not very long, with an abrupt fusi- 

 form club, varying slightly in form, and terminated generally in a hook : 

 head rather large : anterior wings nearly triangular, slightly elongate, posterior 

 rather ovate-triangular, with an obsolete emargination on the hinder margin, 

 and sometimes a rudiment of a tail at the anal angle. Larva pubescent. 

 Chrysalis with the front acuminated. 



Fabricius having restricted his genus Hesperia, in the Systema 

 Glossatornm, to a very different group of this family, I have adopted 

 the name that he has there applied to the indigenous species, in 

 preference to that of Hesperia, which is more generally employed 

 in this country. The species may be known from those of the genus 

 Thymele by the incrassated straight club to tlie antenna*, the 

 superior robustness of the thorax and abdomen, the more acute 

 anterior wings, and by the rather obsolete rudimentary tail at the an;d 

 angle of the posterior wings : their colours are tawny brown, with 

 spots of a paler hue. There is considerable diversity of structure

 chester."— il/r. Haworffi, in page 334 of the P^ntoniological Transactions: 

 according to whom the insects in question are identical with a species he pos- 

 sesses from Georgia,. in America: but may not the reputed indigenous speci- 

 mens, which I have not seen, be rather identical with the Pa. Fritillum,
