occurs in the same faunal region. It differs materially, however, in 

 the clearly written maculation and in the entire absence of the color 

 characters of Mr. G rote's species. 



Mamestra basiplaga, new species. 



Dull fuscous biown, powdered and suffused with blackish. Head and collar 

 paler, more reddish; head with a median cross line, collar with a black band at 

 about middle, above which it is often of the darkest thoracic shade. Disc of thorax 

 varies from a brown mottling to a blackish purple. Primaries with the upper half of 

 basal space and the s. t. space generally, shaded or suffused with reddish brown in 

 the male, this verging toward lilacinous toward the inner margin. Basal line gemi- 

 nate, obscure, usually traceable to a black longitudinal streak which extends almost 

 to the t. a. line and is obvious in most specimens. Another black streak along inner 

 margin at base, seems to be less constant. T. a. line geminate, inner line obscure, 

 outer blackish, as a whole very irregular in course, nearly upright. T. p. line 

 geminate, obscure through the brown area beyond the reniform, distinctly though not 

 strongly incurved in the s. m. interspace. S. t. line irregular, broken, whitish, 

 partly defined by the dark terminal space and in part by the preceding smoky 

 blotches. A black line at base of fringes, which are cut with yellowish-brown. 

 Claviform broad, rather short, triangular, concolorous, defined by a black outline, a 

 black line generally extending from it to the t. p. line. Orbicular round or oval, 

 usually pale ringed; but this varies greatly as does also the filling. Reniform 

 small, oval, narrow, oblique, outer portion always white lined, usually edged with 

 black scales, so that the outer margin stands out by contrast. Secondaries in the $ 

 whitish at base, becoming dusky toward outer margin at apex ; in the 9 smoky 

 fuscous throughout except at extreme base. Beneath, primaries smoky, darkest in 

 the 9 ; secondaries whitish, powdery along the costal area, with a discal spot. 



Expands : 1.12-1.16 inches = 28-29 mm. 



Habitat. — Huachuca Mts., and Southern Arizona, Poling. 



Three males and six females, all from Dr. Barnes. No two are 

 alike, and yet all have a similarity of habitus that brings them to- 

 gether. The general reference is to the vidua series, which the male 

 genitalia seem to bear out from such examination as I could make of 

 the specimens. 



Mamestra imbuna, new species. 



Dark ashen gray, head and lower half of collar often with a reddish tint, 

 primaries with usually a reddish flush beyond the reniform. A distinct black line 

 below the apex of collar. Patagia more or less obviously submarined with black. 

 Primaries with a short curved black streak at base, above which the wing is usually 

 a little lighter. T. a. line rather well removed from base; geminate, even, the outer 

 line best marked, included space gray, as a whole with an oblique outcurve. T. p. 

 line geminate, slender, the inner portion blackish, included space narrowly gray, 

 outer portion often lost ; as a whole even, with a wide bend over cell and a marked 

 constriction in the submedian interspace. S. t. line irregular, broken, preceded by
