Habitat.— Nebraska ; Texas. 



A very peculiar and easily recognized species, bearing no close re- 

 semblance or relation to any other in the genus, and therefore elevated 

 togronj) raidv. The long black basal streak, the small white ordinary 

 spots, and obsolete median lines are characteristic. 



A single specimen from the 13elt'rage material (C. V. R.), marked 

 June 8, is in the Museum collection. The species resembles somewhat 

 Ayrotis plecta \\\ size, form, and color. The harpes of the male are very 

 slender at base, then suddenly and broadly enlarged at tip and greatly 

 produced interiorly. The inner side of the tip is fringed with a row of 

 spinules as usual. The clasper is a small, curved, acute hook. It is 

 perhaps the last preceding group to which this structure most allies 

 the species. 



Group INNEXA. 



The wing form, which has been already described, distinguishes this 

 group, which also is best described in the characterization of its single 

 species.

Reddish fuscous, with blue-gray irroration, all the veins marked with 

 gray scales. Median lines single, narrow, gray. Basal line present. 

 T. a. line upright, with a slight inward tooth on median vein. T. p. 

 line very even, almost rigidly oblique from costa to inner margin. S. 

 t. line very distinct, yellowish, rather close to outer margin, its course 

 slightly sinuate. Orbicular round, pale- margined, rather darker than 

 ground color. Reniform moderate in size, pale linel, interiorly dusky. 

 Claviform wanting. Secondaries of male whitish, with narrow, dark 

 outer margin; of female, dusky, paler at base. Beneath, powdery 

 gray, with an outer line and discal dot. Head and thorax coucolorous 

 with primaries. 



Ex{)ands 28 to 30""" (1.12 to 1.20 inches). 



Habitat. — Texas. 



Six specimens are in the Mu.seum collection (Meske and C. V. R.), 

 two of them labeled by ^Ir. (rrote, one as ririfittiplui, the other as 

 Maiiicsfru iinic.va. The specimens from the Riley collection are of the 

 Belfrage material, and are dated March 29, April 29 and 30. 



The species is distinct and easily recognizable. The depressed costa, 

 acute apices, and oblique outer margin are distinctive. The ba.sal 

 thoracic tuft and dorsal tufts of abdomen are well marked. The harj)es
