Description made from (?) adspersa, H-S. 
Proboscis absent ; palpi till just beyond frons, ascending ; first joint 
almost circular, and with long hair underneath ; second joint about 3 times 
first joint in length, and with long hair in front and above ; third joint 
indistinctly marked off, as long as first joint, bluntly pointed, and with 
long hair in front and above ; eye nearly round, large, of width of frons ; 
antennae bipectinate ; shaft J length of costa, somewhat curved ; in the 
branches are about 8 times the shaft, getting shorter towards base and 
apex, so as to form a straight line, each ending in 2 bristles and most 
branches with a similar bristle pointing forwards at J to § of the branches ;* 
in the 2 the shaft is only J of the costa, less curved, and the branches are 
only 2 times the shaft, but they have the terminal as well as the median 
bristles ; vertex, frons, and thorax covered with long hair ; abdomen 
in $ a little longer, in $ a little shorter, than the hind wing, and covered 
with moderate long hair ; fore tibia with an abruptly pointed process, 
nearly as long as the tibia ; in $ without a process ; mid tibia with end 
spurs ; hind tibia with 4 spurs ; tarsae with short depressed hairs. 
Fore wing of $ triangular ; costa somewhat rounded ; termen straight 
and rounded at 16 to vein 4 ; inner margin arched ; apex and tornus well 
rounded ; vein lb simple at base ; 1c faintly represented ; 2 from § lower 
median ; 3 from before f vein 2 to 4 ; 4 from the angle ; 5 from well 
above the angle ; discocellular faint and curved at middle ; cell over J of 
wing ; 6 from well below upper angle ; 7 and 8 on a stalk of J 7, and 
from upper angle ; 9 and 10 on a stalk of nearly f of 10 and from upper 
median at beyond f ; 9 anastomosing with 8 shortly after it gets free 
and just as 7 comes out of 8, for \ the length of 8, so as to form a rather 
long areole (in one $ specimen the left wing has 7 free from upper angle 
and 8, 9, 10 stalked, the other wing has 7 coming from the areole 
and not typically from end of areole ; in one $ 7 comes from the stalk 
of 8, 9, 10, and 10 comes from the end of the areole ; in six $$ no areole 
is formed at all, but 7 and 8, 9 and 10 are stalked ; 8 and 9 are more or 
less approximate to each other, but never anastomosing to form the 
areole ; this is thus a most interesting example of atavism) ; 11 from 
* Such bristles I have not found in any other genus of this family.
