Neurostrata nov. gen. 



Type: Neurostrota gunniella Busck. 



Head smooth. Antennae 1, basal joint slightly enlarged. Labial 

 palpi moderately long, porrected, smooth, end joint equal to second, 

 pointed, upcurved. Maxillary palpi moderate, filiform, porrected. Pos- 

 terior tibiae with row of bristly hairs above. Forewings lanceolate; 12 

 veins, all well separated, 2 weak at base, 11 from near base, not joined to 

 cell. Hindwings linear lanceolate, acuminate; 6 veins, 4 absent, 2 and 3 

 coincident (in some specimens a portion of 2 is faintly discernible), 5 and 

 6 stalked and connected with 7, base of 7 parallel to 8, in the c? a spiny 

 process at the termination of 8 on the costa. 



A genus related to the Acrocercops group but with 

 wings, complete venation and basal origin of 11, in the fore- 

 wings, and degraded neuration in the hindwings. 



Neurobathra nov. gen. 



Type: Neurobathra strigijlnitella Clemens. 



Head smooth. Antennae 1, basal joint somewhat enlarged, very faint 

 pecten of few hairs. Labial pulpi moderately long, porrected, end joint 

 equal in length to second, pointed up curved. Maxillary palpi moderate, 

 filiform, porrected. Posterior tibiae with row of bristly hairs above. 

 Forewings narrowly lanceolate; 12 veins, 11 from very near the base of 

 cell, 2 and 3 very weak, 3 out of the base of 4, 4 and o widely separated. 

 Hindwings linear-lanceolate; 7 veins, 4 absent. 5 and 6 stalked, 7 close to 

 8 near origin, approaching or connected with stalk of 5 and 6 near middle 

 of wing, costal fold in <f producing deformed neuration. 



This genus may be separated from others in the Acrocercops 

 group by the basal origin of vein 11 and the weakened condition 

 of both 2 and 3 in the forewing and the absence of vein 4 in the 

 hindwing. The venation resembles Micrurapteryx Spuler from 

 which genus it may be separated by the characters of the hind 

 tibiae. 



Parectopa Clemens. 



Type: Parectopa lespedezac faliclla Clem. 



Head with appresscd scales. Antennae 1, with slight pecten. Labial 

 palpi moderately long, curved upward, terminal joint equal second in 

 length, smooth or slightly roughened. Maxillary palpi moderate, filiform, 

 porrected. Middle and hind tibiae smooth scaled. Forewings elongate. 

 acuminate; 11 veins (or sometimes 10), 2 or 3 absent (or sometimes both 

 2. and 3), 6 and 7 often stalked. 11 from about | of cell from base. Hind 

 wings about i, linear lanceolate; 7 veins, 5 and 6 stalked, 4 absent.
