metatlioracic tuft tinged slightly with metallic blue, thus approaching 

 delecta Walk. The anterior wings are perceptibly narrower than in 

 epastroides, having the basal space and the subcostal part of the median 

 space white; a black dot at the base; dark spots, sometimes connected 

 together by bluish-gray shades, mark the inception of the median 

 lines on the costa; the interior line is usually continuous below, bound- 

 ing the dark outer portion of the wings, but in one specimen the 

 dark part only extends to the median shade ; in all the specimens 

 we have there is a distinct black spot on the median nervure in addi- 

 tion to a black dot which appears in the place of the orbicular spot ; 

 the reniform spot is situated on the border of the dark space, is 

 concolorous and surrounded by a dark annulus ; the median shade is 

 ill-defined, interrupted by the costal white space, and followed by a 

 bluish-gray shade, which extends to the indistinct exterior line; the 

 subterminal line whitish, irregular, preceded by more or less distinct 

 black spots ; the subterminal and terminal spaces are dark brown ; 

 there are also some traces of this color after the interior line. A 

 series of black points at the base of the fringe ; the latter is white, 

 shaded with bluish-gray. The posterior wings whitish, translucent, 

 with a suffused terminal blackish border. Beneath, the anterior 

 wings are blackish, with the basal and part of the median space 

 ochreous ; the posteriors are whitish with the costa ochreous, and 

 with a dark terminal border as above. 



Hab. Waco, Texas. 



The smallest species known to us. From candefacta it can be sep- 

 arated by the color and the form of the markings, and from erastroi- 

 des by the shape of the wings.

This species has hitherto been unidentified by American authors ; 

 the Texan specimens agree very well with M. Guenee's description. 

 Our specimens from Nebraska, Missouri and Texas, show but slight 

 variation except in size, the smallest specimens being about 29 mm., 

 and the largest 35 mm. 



Mr. Grote' s fratella, expanding 30 mm., came from the same local- 

 ity as our Texan specimens ; we think it merely a redescription of

This form differs materially from M. Guenee's description, but the 

 species is so variable and so widely spread that we do not dare to
