 Fore tarsi as long as their tibiae, the last four joints of equal length. Wings infuscated along the veins ; 

 costa with just a suspicion of an enlargement ; last section of the fourth vein nearly forming a right angle 

 at its middle, the tip almost exactly parallel with the third for some distance. 

 Length 4*3 millim. 



Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith).
