Hab. — Calgary. Mr. Dod has sent me seveial specimens of 

 this insect which seems to be not uncommon at Calgary in July 

 and August. This species is quite unlike anything else in our 

 fauna and should be easily recognizable from the description. 

 The very even, pale median lines and the pale streak through the 

 lower part of the median space are quite characteristic. 



Noctaa atrlcincta n. sp. Pi. xv, fig. 3. — General color a very pale ash- 

 gray, more or less powdery. The collar is blackish or brown at the base, 

 the thorax is immaculate. On tlie primaries the ordinary lines are sin- 

 gle, variably evident, blackish and diffuse. The basal line is sometimes 

 distinct, sometimes marked only by a costal spot. T. a. line outwardly 

 oblique and rather even in course, usually fairly well defined; but some- 

 times marked on the costa only. T. p. line forming a rather broad out- 

 curve and tolerably even. It is traceable in all the specimens that I have 

 seen, but in one at least, which is figured, the contrast is very slight in- 

 deed. The s. t. line is marked by a dusky preceding shade, merging into 

 the ground color before the t p. line is reached. On specimens in which 

 this shade is best marked it forms the most prominent feature, and the 

 median lines are indistinct. There is a traceable median shade, but it is 

 not complete in any of my specimens and is diffuse in all. At the base 

 of the fringes there is a broken terminal line. The claviform is wanting; 

 the orbicular is absent or barely indicated, and the reniform is a small, 

 black, lunate mark, sometimes emphasized by a whitish dot inwardly. 

 The secondaries are white in both sexes, a little dusky toward the apices. 

 Beneath, the primaries are smoky, the secondaries white, powdered at 

 the costal margin with gray. Expands 35-38 mm.; i. 40-1. 52 inches. 



Hab. — Calgary, in July. This species resembles lubricans in 

 general appearance, and is an ally of that species. I have a 

 specimen from Volga, S. Dakota, which is, I think, the same; 

 but it is somewhat better marked and rather darker, and may 

 possibly represent a distinct species. It seems to be not uncom- 

 mon, judging from the number of specimens sent me. 



Noctaa patefacta n. sp. PI. xv, fig. 2. — The ground color is a rich, dark 

 purplish brown, and tolerably even. The palpi are darker at the sides 

 and the collar is broadly black, or very dark chestnut-brown at base, 

 limited above by a narrow yellowish shade line. The primaries vary 

 somewhat in the depth of the ground, being sometimes almost chestnut- 

 brown and again of a purplish smoky tint. The ordinary lines are not 

 well defined, but all are easily traceable. Basal line black, followed by a 

 few paler scales. T. a line black, interrupted, irregular in width, bisinuate 

 in course and preceded by either a few pale scales, or by a more or less 

 obvious pale line. T. p. line faint, slightly paler than ground color, out- 

 curved over the reniform and very evenly oblique below that point. It 

 is somewhat defined by very feebly marked dark Hues, and inwardly there
