The above description is based mainly on a study of P. robiniella 

 Clem, bred specimens of P. lespedezaefoUella not being available. 

 Clemens in his original description gives 8 as arising out of 7 

 near its base. 



The genus as given above is more narrowly restricted than as 

 given by Meyrick, whose definition would include Micrurapyteryx 

 Spuler, given below. 



Micrurapteryx Spuler. 



Type: Micrurapteryx Kollariella Zeller. 



Head smooth, erectile tufts of scales at either side of crown. An- 

 tennae 1, basal joint moderately enlarged. Labial palpi smooth, por- 

 rected or drooping. Maxillary palpi filiform, small. Hind tibiae smooth. 

 Forewings elongate lanceolate, acuminate; 12 veins, 11 from near base,. 

 6 and 7 stalked, 2 and 3 stalked and weak. Hind wings i nearly linear, 

 8 veins, 4 very weak, 5 and 6 stalked. 



This genus is probably an older form from which Parectopa 

 Clemens, may have been derived. It is apparently more nearly 

 related to Gracilaria than is the case with Parectopa. 



Parornix Spuler. 



Type: Parornix anglicella Stainton. 



Head rough haired, face smooth. Antennae about 1, basal joint mod- 

 erate. Labial palpi moderately long, slightly curved, porrected or sub- 

 ascending, smooth scaled, terminal joint shorter than second, pointed. 

 Maxillary palpi moderately long, filiform, porrected. Posterior tibiae 

 smooth scaled. Forewings lanceolate or elongate lanceolate; 11 veins, 

 one dorsal vein absent (2 or 3, possibly), 6 and 7 stalked, 11 from about | 

 of cell from base. Hindwings, , narrow lanceolate; 4 usually absent, a 

 branch to costa from cell between 7 and 8. 



This genus corresponds to Ornix as given by recent authors. 

 The latter name must unfortunately be ruled out of existence. 

 For a recapitulation of the reasons for the change of name see 

 Walsingham, Biol. Centr. Amer. IV^p. 341, 1909-1915. This 

 genus may be separated from Gracilaria by means of its rough 

 head. 



It may be that the group of species related to guttea Haw. may 

 have to be removed from this genus. Spuler places them under 

 Ornix Tr., and separates them from his genus Parornix. If, 

 however, the name Ornix is to fall it will necessitate the substi- 

 tution of a new name for Ornix Tr., to include the species related 

 to guttea Haw. having a complete venation in the hindwing.
