narrow elongate, oblique, edged by black scales. Reniform narrowly kidney-shaped, 

 upright, somewhat dilated inferiorly, yellowish, more or less black-edged. Secon- 

 daries washed with dull yellow, the outer border darker, smoky ; fringes pale. Be- 

 neath, primaries smoky with a silky lustre ; secondaries powdery whitish yellow, 

 with apex and costal margin darker ; a punctiform extra-median line and a discal dot. 



Expands : 1.44 inches = 36 mm. 



Habitat. — Regina, July 28, at light ; T. N. Willing. 



One male, in fair condition, secured through the kindness of Dr. 

 James Fletcher. The species has the characteristic appearance of 

 members of this genus and is perhaps closer to my trigona than any 

 other. The yellowish longitudinal streak and the narrow, yellow ordi- 

 nary spots are characteristic. 



Perigea flavistriga, new species. 



Head, pale red-brown, darkening to the vertex. Thorax dark brown, almost 

 blackish, base and tip of collar and margins of patagia more reddish. Primaries 

 dark smoky brown, almost blackish, powdery, so that nothing is defined, though all 

 the usual lines and markings can be made out. Basal line marked by a geminate 

 black spot on costa only. T. a. line incomplete, marked on the costa and by a black 

 outcurve in the submedian interspace, otherwise hardly traceable. The basal s] ace 

 is somewhat yellow mottled and a distinct yellow streak extends beneath the subme- 

 dian vein by the t. p. line. T. p. line geminate, the outer line obscure, the inner 

 narrow, lunulate, blackish, emphasized by a yellow powdering which follows it, well 

 curved over the cell and very oblique and even to near the middle of hinder margin. 

 S. t. space is a trifle paler to the s. t. line which is irregular, made up of yellow 

 scales, defined by vague black preceding spots and a generally darker terminal space. 

 There is a broken black terminal line. Claviform not traceable in the specimen. 

 Orbicular narrow, oblong, oblique, incompletely margined with yellow scales, a little 

 paler than the ground. Reniform large, kidney-shaped, incompletely ringed with 

 yellowish, which tinges also the middle of the mark itself. Secondaries smoky; 

 paler, more yellowish at the base ami with an obscure discal lunule. Beneath, pri- 

 maries smoky brown, immaculate ; secondaries dull, smoky yellowish, with a smoky 

 outer line and discal lunule. 



Expands: 1.32 inches =33 mm. 



Habitat. — Lethbridge, Alberta, July 11; T. N. Willing. 



A single female in good condition, from Mr. F. H. Wolley Dod 

 (No. 8). It is a robust species with narrow obtusely rounded pri- 

 maries, the thoracic vestiture flattened hair rather than scales. It 

 belongs with texana in general appearance and habitus. 



The yellow streak is the most obvious characteristic of this spe- 

 cies, which is otherwise powdery and obscurely marked.
