A common and variable species difficult to characterize except by a 

 description of individuals. Common to all forms is the pale somewhat 

 discolorous reniform, the inferior portion dusky ; the general difl'erence 

 in shade of s. t. and terminal space is also constant, as is the slighter 

 difference in shade in the median space itself. About every other char- 

 acter varies. The extreme pale form is generally larger, the lines 

 obsolete, and a tendency to a pale longitudinal shade through the mid- 

 dle of the wing; this I consider the Typical pityclirous form. The other 

 extreme is smaller, the colors dark, the differences in shade decided, 

 transverse lines complete; this is the personata of Mr. Morrison, the 

 type of which is before me. Intergrades of all shades and sizes occur, 

 and usually in these intermediate forms the costa is distinctly gray. 

 As a rule the S is paler and the secondaries are dirty white, darker out- 

 wardly. The thoracic vestitnre is very strongly intermixed with scales. 

 This species has been taken by me iu some numbers on golden-rod in 

 September, usually late in the afternoon — from 3 to 6 p. m. I do not 

 remember taking it at Sugar. 



Carueades infracta Morr. 



1875. Morr., Proc. Bost. Soc. Nat. Hist., xviii, 11.5, Agrotis. 



Fusco-luteous, median and terminal spaces darker. Median lines 

 geminate, distinct. T. a. line upright, but little curved between veins ; 

 t. p. line with a wide outward angulation over cell; incurved beneath. 

 An evenly marked exterior shade from apex to inner margin just inside 

 the s.t.line; thelatterpale, narrow, and unusually irregularand strongly 

 sinuate, its course mostly through the dark terminal shade. Ordinary 

 spots concolorous with pale portions of wing, well defined ; orbicular 

 large, round; reniform moderate, outer side strongly incurved at mid- 

 dle. Claviform outlined, small. Secondaries uniform pale yellowish 

 fuscous. Beneath pale, powdery, with common dark line and discal 

 spot. Head and thorax concolorous. 



Expands 28""" ; 1.12 inches. 



Habitat. — Colorado, Texas. 



A small species with narrow primaries ; not unlike some forms of 

 pitychroun ; but the very irregular s. t. line will serve to separate this 

 form. 



Carneade-s luteola Sniitb. 



1887. Siuitli, Proc. U. S. Nut. Mus., x, 457, Ayrotin. 

 Luteous, with a reddish shade, and somewhat irrorate with black ; a 

 darker shading to outer portion of median space; entire terminal space 

 dark. Transverse lines geminate. Basal line evident. T. a. line 

 slightly oblique outwardly and hardly wavy. T. p. line with outer parts 

 distinct near costa only ; inner portion distinct, fine, evenly crenulate. 

 S. t. line concolorous, preceded by a dusky shade, its course very even ; 

 the line itself narrow, and somewhat remote from outer margin. Clavi-
