HESPERIOIDEA OF AMERICA 93 



mediate between 3 and base of cell. Stigma rudimentary, con- 

 sisting of a few modified scales faintly indicating the position 

 of the structure ; well developed in a few species, where it is sim- 

 ilar to that of Atrytone but more slender. Mid tibiae spiny. 

 Fig. 28. 



The absence of yellow-fulvous, frequent occurrence of gray 

 scales on the under surface of the wings, and the acute apices of 

 the primaries in the males of most of the species give this genus 

 a very distinctive habitus.

The dark brown ground color and the pure white, opaque spots on the 

 under surface of the secondaries separate loammi readily from the rest 

 of the genus.
