THE CANADIAN ENTOMOLOGIST. 213 



Third submargiiial cell along the radius as long as the second, along 

 the cubitus only half its length, the third transverse cubitus 

 strongly curving outward and then upward ; marginal cell broadly 

 truncate at apex, so that with the long appendage it appears 

 almost two-celled ; hind wings with two discal cells, the second 

 only about half the length of the first ; claws cleft. (^ with only 

 three submarginal cells, the transverse cubitus entirely wanting, 



antennpe furcate Neoptilia, Ashm., n. g. 



(Type N. viexicana, Ashm.) 



Subfamily II. — Hylotomin^.. 



This group closely resembles the former, but the presence of a short 

 transverse nervure in the costal cell readily distinguishes it. It is a char- 

 acter common in the families which are to follow, and its position and 

 shape or direction appears to be of great taxonomic value. 



The genera recognized may be separated as follows : 



Table of Genera. 



Marginal cell appendiculate 3. 



Marginal cell not appendiculate 2. 



2. Front wings with three submarginal cells, the first and second each 



receiving a recurrent nervure ; middle and hind tibiae without a 

 lateral spur; third antennal joint in $ [u.rca.te. ..Micrarge, Ashm., n. g, 



(Type A. ruficollis, Nat.) 



3. Cubitus originating from the apex of the basal nervure or in the angle 



formed by it and the subcostal vein 4. 



Cubitus originating from the subcostal vein more or less remote from 

 the apex of the basal nervure. 



Front wings with four submarginal cells, the second and third 



each receiving a recurrent nervure Hylotovia, Latreille. 



(Section I.) 



4. Front wings with four submarginal cells, the second and third each 



receiving a recurrent nervure. 



Hind wings with a lanceolate cell ; middle and hind tibia; with 



a lateral spur Hylotoma, Latreille. 



(Section II.) 

 Hind wings without a lanceolate cell ; middle and hind tibis 



without a lateral spur Gymniopterus, Ashm., n. g. 



(Type G. sifigularis, Ashm.)
