AMERICAN LEPIDOPTERA. 101 



^■eneral character it will be known by its evenly colored primaries, 

 destitute of prominent shades and lines, and tending to become of a 

 concolorous brown. 



Drasteria mundula, n. s. (Plate 4, fig. 35, 9 •) 



9 ■ Obscure olivaceous testaceous cinereous. Head and body parts, 

 concolorous, except that the color is a little deepened over the protho- 

 rax, and becomes paler, more testaceous, over the abdomen terminally 

 and beneath. Antennae, simple. Hind tibiae with a middle and ter- 

 ninal pair of spurs. 



Anterior wings with a faint brownish tinge, but generally concolor- 

 ous with the body ; the squamation is finely intermixed with darker 

 scales. The conformation of the median lines is like that in D. agri- 

 cola, but these are more distinct, dark, and edged externally and in- 

 completely with pa'e scales, which are tinged with testaceous. A 

 black antemedian discal dot. Median shade line evident, dark, run- 

 ning downwards from costaand apparently joining the upward (second) 

 sinus formed by the union of the median (transverse anterior and pos- 

 terior) lines, but in reality diverging inwardly and running over the 

 first sinus as in D. agricola. The serrate transverse posterior line is 

 succeeded by three or four black shaded points as in D. agricola. The 

 evenly dentate, subterminal line is inaugurated below costa subapically 

 by two super-posed, shaded black marks as in J), erichtea and D. 

 erichto, and is succeeded by a series of continued interspaceal black 

 marks or short dashes. Secondaries, paler, more testaceous than pri- 

 maries, their ornamentation is as in the before-mentioned species, but 

 the two median dark shade lines are farther apart; towards internal 

 margin this is especially noticeable, since here in D. erichtea and D. 

 erichto the lines converge, the median line projecting a more promi- 

 nent inflection downwards on the outer subterminal line, which latter 

 is usually somewhat retired to receive it. Under surface, pale, some- 

 what ochreous. Common blackish transverse lines cross the wings, 

 more widely separate than usual. 



Expanse^ $ , 1.85 inch. Length of body ^ 0.75 inch. 



Habitat. — Atlantic District. (Pennsylvania!) 



A larger species than D. erichtea, and differing by the absence of 

 the prominent dark shades accompanying the transverse lines, and the 

 faint purplish hue of the primaries above, which are never lost in that 

 species. From D. agricola, it differs by the color of the primaries 

 above and the greater distinctness of the ornamentation.
