On reviewing these two plans of distribution of tlie Hesperidse, it will be evident, that whilst certain groups are adopted by both 

 Hiibner and Latreille, they have respectively carried their subdivisions much too far ; raising, in fact, characters which are merely 

 specific into sectional ones. In the following pages I have endeavoured to seize upon the more evident groups. A great number of 

 species, however, which I have not had an opportunity of examining, and which it is impossible, from the too slight characters given of 

 them by their describers, to refer to their natural position, I have been compelled to arrange together at the end of the genus 

 Hesperia. 



Genus I. PYRRHOPYGA. 



Pyrrhopyga, Mimoniades, and Peoteides p. Hiibner. 

 Tamyeis Swainson. 



Body very robust ; wings small in comparison with the body ; head and tail often clothed with scarlet or orange 



hairs. 

 Head large, with the labial palpi convex, closely pressed against the face, with the terminal joint extremely minute 

 and sliglitly deflexed. 

 Antennce rather short, thick, not ringed ; terminated by a curved elongate robust club, obtuse at the tip ; being 

 more attenuated and slender in the females. 

 Wings when at rest, extended outwardly in a horizontal position. 



Fore Wings elongate-triangular, with the apical margin entire, convex towards the apex. Discoidal cell much 

 elongated. The lower disco-cellular vein very obUque, and uniting with the third median branch at a con- 

 siderable distance from its base. 

 Hind Wings small, subtriangular, entire ; the anal angle more or less produced and rounded. 

 Fore Legs with short tibise, armed with a central spur. 

 Hind Legs with the tibia) armed with two subcentral, and two apical, spurs.
