SMITH, NEW NOCTUIDM 123 



the latter a series of alternate brown and pale marks to the apex. The basal line 

 does not extend much below the costal spot. T.a. line single, narrow, broken, 

 irregular, inwardly obhque. T.p. line single, broken, very irregular, outwardly 

 bent over cell, and partly obsolete at that point. S.t. line pale, very irregular, 

 preceded by a dusky shading, which may be emphasized by still darker, more sagit- 

 tate spots. A series of black terminal lunules, beyond which the fringes are cut with 

 pale. There is no obvious orbicular. Reniform a narrow black line or lunule, which 

 may or may not be margined outwardly with whitish. Secondaries uniformly 

 smoky brown. Beneath, smoky, varying in tint; the primaries always darker, 

 with the white costal dots of upper side reproduced; the secondaries more whitish, 

 tending to a dusky outer margin.

Habitat: New Brighton, Pa., July 22-Aug. 11. 



Nine examples, all males and mostly in good condition. The species 

 at first sight resembles the deltoid species of Megachyta by the prominent 

 brown costal spots. There is little variation in the examples before me, 

 except in the amount of the dusky overlay. In the best examples this 

 extends from just beyond the base to the outer margin, becoming gradually 

 more intense, so that the pale s.t. line stands out clearly in contrast; in the 

 poorest examples the dusky tint remains over the terminal area only, and 

 the s.t. line loses in relative distinctness. The abdomen is smoothly scaled, 

 with a small dorsal scale-tuft at base in the better specimens. Beneath, 

 the legs are dusky and the tarsi narrowly pale-ringed. 



The species seems to be not uncommon at New Brighton, but I have 

 none at present from other sources. 



Erastria humerata no v. sp. 



Head and coUar chocolate-brown; thorax and ground-color of primaries gray 

 with an overlay of yellowish pale brown scales. Primaries with median space filled 

 by a blackish-brown shading and a sub-quadrate patch of the same color on costa 

 in s.t. space. Basal line brown, extending to median vein, and from it, to base of 

 wing, is a dark chocolate-brown spot, which looks like the extension of the collar. 

 T.a. line dark brown, irregular, a little inwardly obUque, outwardly diffuse, preceded 

 by a whitish line or shade. T.p. line blackish, broken, irregular, abruptly and 

 squarely exserted over the cell. This outward exsertion of the paler ground occurs 

 beyond the linear black reniform, so that at first sight the t.p. line seems to cross 

 the wing with only a slight outward curve. Outwardly the t.p. line is bordered by 

 pale scales. S.t. line pale, very irregular, forming a broad inward angle opposite 

 the cell, and an almost equal outward angle between veins 3 and 4. As a whole, the 

 s.t. space is a little smoky, darkening to the large brown costal patch. Terminal 

 space usually paler and a little more brown than the rest of the wing. A series of 

 distinct black terminal lunules, beyond which the dusky fringes are cut with yellow- 

 ish. Orbicular wanting. Reniform black, linear, upright. A series of three white 

 dots on costa between t.p. and s.t. lines. Secondaries uniform smoky. Beneath,
