Head small, oval ; eyes small, oval, placed close together ; 
antennae long and slender with about 35 segments, the two 
basal ones several times as long as broad, the others about 
twice as long as broad ; thorax broad ; prothorax long, nar- 
row, mesothorax short, metathorax about twice as long 
as the mesothorax; legs short and stout; femur and tibia 
nearly equal in length; 3 tarsal joints, the last bearing a 
pair of small claws; the last tarsal segment of front legs 
only a little longer than the others, the last tarsal joint 
of the middle legs about twice as long as the others ; hind 
legs and basal segments of abdomen unknown; terminal 
four abdominal segments about twice as broad as long; 
last segment rounded posteriorly, bearing two very long, 
slender cerci, consisting of at least 52 segments (probably 
more), each segment with a pair of divergent hairs. 
Wings moderately slender, nearly subpetiolate, apex well 
rounded; Rs divides into R2 + 3 and R3 + 4 about half way 
between its origin and termination; R2 + 3 terminates at 
the very apex ; cross-veins constant in number, but variable 
in position. 
Genotype: Doter minor Sellards.

optera in the genus Asthenohymen. Apparently the mem- 
bers of this genus rested with their wings back over the
