NO. 1203. NEW NOCTUID MOTHS— SMITH. 425 



Expanse, 35 to 40 mm. =1.40 to 1.60 inclies. 



Habitat. — Placer County, California, in September. 



Mne males and three females from the U. S. National Museum, col- 

 lected by Mr. A. Koebele. There is very little variation in the series, 

 save such as is caused by a staining in either a moist cyanide bottle, 

 or a softening" jar containing too much carbolic acid. 



The form of the orbicular is the only changeable feature, and this is 

 not alike in any two specimens. The species belongs to the pitychrous 

 series and has some resemblance to cogitans, lacking, however, the 

 black basal streak of the latter species. 



Type.— Ca,t. l^o. 4797, U.S.N.M. 



14. CARNEADES MEGASTIGMA, new species. 



Ground color dull luteous gray. Head, collar, and thorax immacu- 

 late. Thoracic vestiture thin and slightly flattened hair, neither pata- 

 gia nor tuftings well marked. Primaries rough with black powder- 

 ings, the maculation obscure. Basal line geminate, marked by 

 scattered scales only or obsolete. Transverse anterior line upright or 

 nearly so, outcurved in the interspaces, geminate, but the inner element 

 barely traceable. Tran verse j)osterior line geminate on the costa and 

 to the angle opposite middle of cell, thence single, broken, hardly lunu- 

 late, smoky, almost rigidly oblique to the margin. Subterminal line a 

 little paler, powdery, somewhat defined by a preceding powdery shade, 

 which may be absent. A very narrow, broken terminal line, followed 

 by a yellow line at the base of the fringes, l^o obvious median shade; 

 but in one specimen there is an indication that it might be expected 

 in a large series. Claviform indicated by smoky scales. Orbicular 

 very large, oblique, of the palest ground, defined at the sides only. 

 Eeniform large, broad, almost oblong or only feebly kidney-shai^ed, 

 space between the spots forming a smoky V. Secondaries smoky, 

 whitish toward base, with a discal lunule and veins dusky, fringes 

 white. Beneath, primaries even, dull gray, secondaries more whitish, 

 both with a vague discal spot. 



Expanse, 33 to 38 mm. = 1.32 to 1.52 inches. 



Sahitat. — Edge Calgary, August 24; Calgary, September 15, Can- 

 ada (Dod). 



Two females; one, the smaller, in good condition, the other lacking 

 one primary and an abdomen, lost in the mail, but otherwise good. 

 The smaller specimen is the more evidently marked and is quite pow- 

 dery; the other is more even and, the powdering being absent, the 

 markings are much less distinct. The species has the color of acornis, 

 and may for the present be placed in that series. 



Type.— Gat. No. 4811, U.S.K.M. 



15. CARNEADES STIGMATALIS, new species. 



Ground color a somewhat light reddish brown, shaded with blackish 

 scales along the veins and sometimes over the entire surface, so as to
