Palpi short to long, slender to heavy, })orrect or drooping ; front 

 not strongly tufted ; antcnnie filiform, ciliate in both se.xos ; thorax 

 untufted. Alxlonien witli tuft on each segment dorsallv ; fore tibiie 

 unarmed, hind tibiie with all s[)urs; fore wings 12 veins, two acces- 

 .-^ory cells ; hind wings 8 with cell to beyond middle, (> and 7 separate 

 or stemmed. 



A large genus as defined, consisting mostly of small sj)ecies. The 

 .species so gradually merge into one another in structure, and are .so 

 largely midway between the extremes that I have not attempted any 

 closer limitations, and so do not give a more exact generic diagnosis.
