Table for Separating the Species of Trichogratnniatoidea. 



1. Fore win^s with the longest (distal) marginal cilia equal in length, 



or nearly, to the longest (caudal) marginal cilia of the hind 

 wings, the former being about a third as long as the great- 

 est width of the fore wing. Fumated area of the fore wing, 

 extending distad to the distal end of the stigmal vein, its 

 distal margin straight ; stigmal knob rounded ; club of 

 female antenna stouter, not more than two and one-half 

 times longer than wide liana Zehntner. 



2. Fore wings with the longest (distal) marginal cilia distinctly 



shorter than the longest (caudal) marginal cilia of the 

 hind wings, the former not more than a fifth as long as the 

 greatest width of the fore wing. Fumated area of fore 

 wing extending distad only as far as the middle of the 

 marginal vein, its distal margin oblique ; stigmal knob 

 ovate ; female antennal club slenderer, about three and 

 one-fourth times longer than wide llltea Girault. 



4. USCANA genus novum. 



Normal position. 



Female. — Head rounded, normal, the eyes ovate, the antennae 

 inserted slightly ventrad of the middle of the face, 6-jointed, 

 short and moderately stout, consisting of a scape, pedicel, 

 very minute ring-joint and a 3-jointed club ; funicle absent. 

 Body short and compact, the abdomen cylindrical but short, 

 not any longer than the head and thorax together, the ovi- 

 positor not exserted, the abdomen barely longer than the 

 thorax, usually abruptly obliquely truncate ventrad. Fore 

 wings fumated proximad, moderately short and moderately 

 broad, oblately nearly flatly rounded at the apex somewhat 

 as in Chaetostricha Haliday but not nearly so broadly or flatly
