of Orenaia trivialis B. & McD. ; some whitish scattered scaling at base and 

 in cell and a better defined s. t. band of whitish scales becoming obsolete towards 

 apex of wing. Secondaries deep smoky with darker shade near outer margin 

 between veins 2 and 3 outlined outwardly partially by a paler shade. Beneath 

 silvery with a slight smoky tinge, primaries with discal dash and faint s. t. 

 line; secondaries with discal spot (which appears closer to base of wing than 

 usual owing to the shortness of the cell) and a curved dark indistinct s. t. 

 line bent downward at anal angle ; fringes on both wings smoky. Expanse 

 20 mm. 



Habitat: Nebraska Hill near Tolland, Gilpin Co., Colo. (July 5). 1 $. 

 Type, Coll. Barnes. 



The specimen was sent us by Prof. T. D. A. Cockerell through 

 whose kindness we are permitted to retain it. It is in rather poor 

 condition and we should have hesitated to describe it if it had not 

 been for the structural characters and the characteristic under side 

 which should render the species recognizable ; from trivialis it may 

 be separated by the very hairy palpi which in trivialis are smooth 

 scaled. It is probably a day flyer, our specimen having been captured 

 sitting on the flower of Silene acaulis. 



Phlyctaenia angu.stalis sp. nov. (PI. XXII, Fig. 19). 



Primaries long, narrow, light mouse gray somewhat darker in costal area ; 

 maculation rather indistinct ; t. a. line black, inwardly oblique with a prom- 

 inent outward tooth in the cell, preceded on inner margin by a slight white 

 dash and dark spot ; t. a. line gently rounded and slightly dentate from costa 

 to vein 4, sharply bent inward to beyond reniform with slight outward tooth 

 in fold and then parallel to t. a. line to inner margin ; beyond the t. p. line 

 is a pale shade, narrower in costal portion, broad above inner margin and 

 defined slightly outwardly by a darker line; a dark subapica! shade; veins 

 apically partially outlined in black; reniform narrow, indistinct, partially out- 

 lined in black, pale filled ; terminal dark dots not reaching anal angle ; fringes 

 dusky, slightly white-spotted. Secondaries hyaline smoky with curved post- 

 median dark line, prominently dentate below costa; a triangular smok>' shade 

 on outer margin between veins 2 and 4; terminal dark dots on veins, most 

 distinct on the dark patch ; fringes smoky, cut by a pale median line. Beneath 

 smoky with a dark reniform mark on primaries and dentate postmcdian line 

 crossing both wings ; terminal dark dots, most prominent on secondaries. Ex- 

 panse 34 mm.

The large size and long, narrow primaries render the species easily 

 distinguishable ; it belongs in the itysalis group.
