of wings the subcosta is connected to the costa by three or four cross-veins, and 
in all wings there is a strong, oblique cross-vein beyond the end of the subcosta, 
which with the other veins near by tends to form an X, not however as distinct 
as in Nemotira; in the fore-wings the cubitus at end of series of cross-veins curves 
upward toward the branch of median vein, thus forming a very large cell. Type 
— 7! analis 
This genus combines the characters of Ne?noiira and TiEu aplcryx, especially 
that section of I'aniopteryx called RhahiRoptcryx by Klapalek. It differs from 
all 7'ieniopteryx groups by the s trong cross-vein beyond the subcosta, a character 
of Nevioura: from Nemoura it is well separated by the long second tarsal joint, 
and the costal cross-veins, the latter character found also in Rhaluliopteryx. The 
subgenital plate of the male is much like that of the European CFniopteryx locwii 
Alb., but still larger.
