HESPERIOIDEA OF AMERICA 99 



toward base, a little nearer to 4 than to 6 ; secondaries rounded, 

 in most of the species longer through the cell than in the related 

 genera. Male stigma small, sometimes scarcely \'isible, composed 

 of a short, oblique dash above the base of vein 2 and a smaller 

 longitudinal dash below it. Middle tibiae spiny. Fig. 29. 



The checkered fringes of this genus are a convenient super- 

 ficial character, and indeed the only one by which nanno can 

 readily be placed. The other species are readily referred to the 

 genus by the long third joint of the palpi, taken with the api- 

 eulus of the antennae. "Whether nunnc should be left in AmbJy- 

 scirtes is a question which I have been unable to settle ; its sim- 

 ilar habitus would cause me to hesitate to remove it. 



Key to the species
