distinct, black lined, making a long narrow loop from base almost to the 

 middle of the wing. Tbe orbicular is reduced to a dusky or blackish in- 

 definite elonj'.ate streak. Tbe reniform is replaced by a blackish lunule 

 at the end of the cell, around which is a variably diffuse and indefined 

 shading. The veins are black marked, and with narrow accompanying 

 whitish shades, which are most prominent on veins three, four, six, and 

 seven, A whitish subcostal shading and a paler more yellowish shade 

 from the end of the claviform to near the anal angle. Secondaries 

 whitish fuscous, darker in the female. Beneath whitish, primaries 

 with disk dusky, both wings with a discal lunule. Expands 37-39'""', 

 1.50-1.55 inches. 



Habitat. — Colorado. 



Four specimens, S and 9 , are before me, all of them collected by 

 Mr. Bruce — one ot them from Mr. Angelman, the others from the col- 

 lection U. S. NatioTial Museum. All are very much alike, ditfering 

 only in the relative brightness of the maculation. 



The genus Porosagrotis is proposed for a series of species of which 

 mitrcvnula is type, agreeing with Carneades Grt. in structure save as to 

 the $ genitalia, the clasper in Carneades being lengthily bifurcate, 

 while in the new genus it is always a single curved corneous more or 

 less hook-like process. The present species is allied to orthogonia and 

 dollii in the shortly i^ectinated antenn;TB, having the wing form of the 

 latter species. The strigate maculation and the narrow loop-like clavi- 

 form easily distinguish it from all its allies. The body is very robust, 

 and the thoracic vestiture thick, giving the species a very jilump ap- 

 pearance. 



Carneades neomexicana sp. nov. 



Ground color of head, thorax, and primaries a somewhat yellowish 

 brick-red. Head inferiorly whitish. Collar inferiorly bright pale gray 

 and tipped with the same color. Patagiiic marked discally with bright 

 blue-gray, the thoracic tuftings, which are evident, marked by the same 

 shade. Costal region of primaries bluish-gray, this shade sometimes 

 extending also along internal margin, along the apical venules, and al- 

 ways along the median vein, branching on veins four and five and in- 

 denting the terminal space. Basal line indicated below median vein, 

 geminate, paler, defining lines blackish. T. a. line distinct only below 

 costal region, paler, outer defining line black, inner concolorous. T. j). 

 line pale, geminate, the defining lines scarcely darker, usually indistinct 

 below veins three and four, and sometimes the line is obsolete below 

 the cell. S. t. line concolorous, marked by the dark terminal space and 

 a dusky preceding shade, indented usually about half way across the 

 terminal space on veins three and four. A series of fine terminal dots. 

 Claviform small, black margined. Orbicular oblong, oblique, usually 

 open to costa, black winged, then with a whitish annulus, center of 

 palest shade of ground color. Reniform upright, moderate in size, normal 

 in form, with a very narrow black and slightly paler annulus, centre uui-
