Guenee's description is clear and covers the species in which the s. t. 

 line is prominently black shaded on costa while the new species lacks 

 these black shadings completely, has the median lines more regular and 

 has an obvious reniform. I have seen others, though I have only one 

 pair at hand, and I have no doubt that its distribution will prove to be 

 much the same as that of dormitans. 

 Charadra ingenua, new species. 



Resembles deridens in general appearance and type of maculation but paler 

 throughout. The primaries are of a decided bluish gray with the maculation neatly 

 written and the secondaries are whitish or white, without trace of yellow and scarcely 

 a trace of smoky toward the outer margin. 



Expands. — 1.40-1.50 $, 1. 72-1. 76 tf = 35-44 mm. 



Habitat. — Glenwood Springs and Durango, Colorado; end of 

 June and beginning of July : Dr. Barnes. 



Two males and two females in good or fair condition. I have for 

 comparison seven examples of deridens, ranging from Canada to Florida 

 and west to Pittsburg, and all agree in having a creamy tint to the 

 gray of primaries and a decidedly yellowish shade to the secondaries. 

 The absence of these shadings in the Colorado examples is the most 

 conspicuous character, accompanied and emphasized by neater, better 

 defined and yet less conspicuous maculation. The small departures 

 from the eastern type in actual course of lines, etc., need not be spe- 

 cifically described. 

 Bryophila avirida, new species. 



In size, wing form and general type of maculation very like B. lepidula, with 

 all the green shadings eliminated. In the four examples before me and in comparison 

 with the type form, none is as well marked as normal lepidula and the only well 

 denned maculation is the brown shading on the costa between the orbicular and reni- 

 form spots. None of the maculation is as well marked in the western as in the east- 

 ern form and it seems probable that, while closely allied, we have a really distinct 

 species. 



Expands. — 1. 06-1. 24 inches = 26-31 mm. 



Habitat. — Fort Collins, Colo., in June ; Cartwright, Man., in June. 



This species may be mistaken for lepidula until a careful examina- 

 tion is made, for the type of maculation is identical and the one is 

 undoubtedly a descendant from the other; but when carefully com- 

 pared the differences are sufficient in my opinion to authorize the new 

 name. 

 Noctua monteclara, new species. 



Head, thorax and abdomen of an almost uniform mouse gray ; collar and patagia 

 evident, but not prominent, vestiture mostly flattened hair. Primaries mouse gray
