 middle of the hind margin ; the radial cross-vein present ; the free part of 

 Rg always present ; the radio-medial cross-vein usually present ; the 

 medio-cubital cross-vein and the free part of Mg^^ parallel ; the hind wings 

 with the free part of R^ and the transverse part of M2 present or wanting ; 

 the antennae with nine segments. 



CocKERELLONis, H. gen. — Front wings with the second abscissa of Cu 

 distinctly longer than the free part of M^ ; the free part of 2nd A perpen- 

 dicular ; the radial and the radio-medial cross-veins present ; the hind

 the transverse part of Mg present ; the posterior metatarsus shorter than

 great part, the femora narrowly at base and apex, more pronounced on 

 the anterior, the tibiae except fuscous marks on the outside of the middle 

 and posterior, the base of the tarsi, and the apex of the ventral abdominal
