Xylomiges dolosa, n. s. 



Professor C. H. Fernald has sent me a fresh female specimen which 

 evidently belongs to an undescribed species of Xylomiges, and for which 

 I propose the specific name dolosa. The species is black and grayish 

 white, the black dull and lustreless. Eyes hairy, abdomen a little flat- 

 tened, the tufts are not discernible. Size of Mamestra adjuncta. Thorax 

 black, with gray shading on collar and tegulae ; abdomen blackish. Pri- 

 maries with the ordinary spot grayish white, of the usual size, reniform 

 upright. Posterior line even, double, followed by venular points. Sub- 

 terminal line even, whitish, preceded by black cuneiform marks. Terminal 

 space gray, veins marked with black. Fringes black, neatly marked with 

 gray. Hind wings whitish, powdered with fuscous, without marks, beneath 

 with a distinct dark discal spot. The species is remarkable for the even- 

 ness of the subterminal line, which wants the usual indentations. The 

 wings are rather long and the somewhat depressed body gives it a resem- 

 blance to LitJwphane. It may be ultimately referred to Mamestra, but the 

 thorax and abdomen are untufted, the hind wings rather long and with 

 well marked exterior sinus. 



Mamestra defessa, n. s. 



Also allied to trifolii, but with the subterminal line irregular and 

 dusky ; reniform concolorous with an inferior black stain. The fore wings 

 are pale ochrey clay color, the lines double, faint, stigmata concolorous, 

 with dark defining lines. Thorax concolorous with primaries ; no lines 

 on the collar. Hind wings whitish at base with discal lunule and broad 

 exterior fuscous band. Beneath there is a discal cloud and common extra 

 mesial dotted line, which is joined to the discal spot on primaries by
