Rhizagrotis perolivalis, new species. 



Hear], thorax and primaries gray, overlaid by a dark olive. Mead with white 

 scales intermixed and with the lower half whitish. Collar whitish below a median 

 black transverse line, and sometimes white tipped. An oblique -white line on the 

 patagia from the costal insertion of primaries to the anterior divided crest ; edges of 

 patagia also white in one specimen. Primaries with the costal region whitish to the 

 t. p. line and the s. t. space with whitish powderings. Basal line distinct, white, 

 with black scale edgings. T. a. line white filled, outwardly defined by a broad, 

 somewhat diffuse black line, inwardly by a smoky line ; in course almost upright to 

 the submedian vein, outcurved in the interspaces, with a long outward bend below 

 vein I. T. p. line almost parallel with the outer margin ; geminate, outer line 

 incomplete, narrow, even ; inner line narrow, a little crenulate, blackish, included 

 space more or less whitish. S. t. line of the pale ground or whitish, preceded by 

 black sagittate spots so arranged as to give the appearance of white rays on veins 3 

 and 4 and 6 and 7. A narrow black terminal line. There is a black edging below 

 the median vein in the basal space. A yellow bar extends from the end of the clavi- 

 form to the t. p. line. Claviform concolorous, narrow, rather elongate, edged with 

 black. Orbicular narrow, oblique. Mark-edged, white tilled. Ren i form kidney- 

 shaped, rather narrow, black-edged, whitish powdered. Secondaries pale smoky 

 yellowish, outwardly darker, the fringes white. Beneath gray, powdery, especially 

 toward the margins. 



Expands : 1. 36-1. 40 inches — 34-35 mm. 



Habitat. — Calgary, Alberta, head of Pine Creek, July 9, 10, 14. 



One male and three females, all in good condition from Mr. F. H. 

 VVolley Dod. The species has a close superficial resemblance to the 

 4-dentata series of Euxoa, and with only the female at hand I asso- 

 ciated it with olivalis. The receipt of the male and of additional 

 females makes it possible to determine the genus in which the species 

 has no close allies, superficially. It may be that terrealis which I 

 referred to Chorizagrotis will eventually be associated with this species 

 in Rhizagrotis or that because of the general agreement in type of 

 maculation, perolivalis will go to Chorizagrotis. 



Noctua acarnea, new species. 



Head and collar deep, almost purplish brown ; collar with a blackish transverse 

 line ; disc and thorax more reddish, patagia almost carneous, and much brighter 

 than any other part of the insect. Primaries very dark, almost blackish brown, with 

 a purplish tinge, with a reddish shade in the upper portion of median space, most 

 obvious in the reniform. Basal line geminate, broken, outer part of line blackish, 

 inner obscure, included space reddish ; as a whole, nearly upright. T. p. line ob- 

 scurely geminate, irregular, with an even and not very marked outcurve. Inner part 

 black-marked, emphasized by some reddish scales following. S. t. line somewhat 

 irregular, reddish, punctiform, a little emphasized by darker shadings. Fringes 

 concolorous. Claviform small, incompletely outlined, obscurely shaded with reddish.
