gether in the genus Hesperia contain many natural genera, but 

 which the paucity of species generally found in cabinets prevents 

 us from discriminating. Having for a long time paid attention 

 to this family, and possessing near 300 species in my own cabi- 

 net, I have had the opportunity of attempting their elucidation ; 

 and the above generic character is applied to those insects only 

 which I propose considering genuine species of the genus Hes- 

 pei'ia, and which will comprise near 1 70 species. 



1 have named this new, undescribed and very rare insect, in 

 honour of my esteemed friend A. H. Haworth, Esq. F.L.S., &;c., 

 well known by the benefits his writings have conferred on the 

 sister sciences of entomology and botany. The only two insects 

 I ever saw of this species I captured in the southern part of 

 Brazil.
