THE CANADIAN ENTOMOLOGIST 225 



on both wings and much as in nevadensis Stretch; from this latter 

 species, apart from their more transparent appearance, they may 

 at once be distinguished by the thoracic vestiture, which is black, 

 not pale yellow, as is found in nevadensis. The discal spot of 

 secondaries in the Manitoba race is generally shorter and shows 

 much more tendency to obsolescence than in either lucina or 

 nevadensis. 



Types — Five d^'s, one 9, Aweme, Man. (Criddle) (Sept.) in 

 Coll. Barnes. 



NOCTUID^. 



Ipimorpha viridipallida, sp. nov. 



Primaries pale greenish ochre, with the usual markings of 

 the genus, consisting of an outwardly oblique white t. a. line, 

 slightly bent inwards in the central portion, an almost straight 

 t. p. line, slightly angled opposite the cell, a faint and strongly 

 irregular s. t. line defined inwardly by greenish shading, a large 

 round orbicular outlined in white and a similarly outlined upright 

 reniform constricted in the middle; claviform very faintly outlined 

 and appressed to the t. a. line. Secondaries almost pure white, 

 with a faint dark curved postmedian line crossing the central area 

 of the wing. Beneath whitish, with a faint postmedian line crossing 

 both wings. 



Expanse 35 mm. 



Types — Six cf's, two 9 's, Truckee, Calif, in Coll. Barnes. 



Most closely related to nanaimo Barnes, with practically 

 identical markings; the pale greenish colour of primaries and the 

 white secondaries readily separate it, however, from this species. 



Abrostola parvula, sp. nov. 



Thorax gray and brown mixed, posterior tufts light brown. 

 Primaries with basal area to t. a, line brown, shaded with whitish 

 at extreme base; t. p. line geminate, inner line faint, outer sharp, 

 black, slightly angled below costa, rather evenly rounded to vein 1, 

 where it bends outward, forming a slight but noticeable angle; 

 median area dark blackish brown, containing the pale orbicular, 

 subreniform and reniform spots the former two placed obliquely
