246 REVISION OF MAMESTRA SMITH. 



Secondaries fusco-luteous, darker outwardly. Beueath, powdery, with 

 darker outer Hue and discal spot. Head and thorax concolorous with 

 primaries, collar with a dark line. 



Expands 32-35""" (1.28 to 1.40 inches). 



Habitat. — Canada; Northern, Eastern, Middle, and Central States. 



Eight specimens are in the Museum collection : Maine (J. B. S., C. 

 V. li.); Lewis County, New York, July 4 (Meske). 



A modestly marked species, rather variable in the amount of dark 

 shading to the primaries. The type of Mr. Morrison's illabefacta is a 

 pale specimen, but not entitled to rank as a variety. The rather con- 

 trastingly dark terminal space and even s. t. line will serve to identify 

 this species. 



The harpes of male are bent toward tip, the angle somewhat pro- 

 duced and corneous, at tip enlarged into a concave lappet, which is 

 somewhat acutely produced at its upper edge. Inwardly it is friuged 

 and densely matted with spinules. At the angle there is a small beak- 

 like i^rocess. The clasper is single, rather short, and moderately stout.

Bluish or violet gray. Median space, terminal space, superior por- 

 tion of basal space, and a costal patch in s. t. space red-brown. Basal 

 line hardly traceable. A short, black longitudinal dash. T. a. line 

 outwardly oblique, somewhat curved, and slightly dentate on the veins, 

 obsoletely geminate. T. p. line parallel with outer margin, even. S. t. 

 line very even, yellowish, marked by the dark terminal space and a 

 preceding row of black spots. Apex pale. Claviform small, narrow, 

 concolorous. Orbicular pale, narrow-ovate, oblique. Reniform con- 

 stricted at middle, slightly oblique, with yellow annulus, else concolor- 

 ous. Secondaries yellowish at base, outwardly fuscous. A dark discal 

 lunule. Beneath yellowish, with darker discal dots and outer margin. 

 Head and thorax concolorous with primaries, collar with a dusky line. 



Expands 32""" (1.28 inches). 



Habitat.— Maine. 



A single specimen, without locality, is in the Museum collection (C. 

 V. E.). 



The species is easily recognized by the yellowish secondaries and the 

 very rigid, broad s. t. line. 



The harpes are bent near tip, where they are enlarged, as in legitimay 

 aud furnished at tip with a long, stout spine. Tip with only a iriuge 

 of si)inules. Clasper very simple, consisting of a slightly curved and 

 rather slender, corneous hook.
