darker between the basal and t. a. line until a conspicuous black band 

 appears ; the s. t. space in turn may also become darker until it is com- 

 pletely black-filled ; one example, with basal and s. t. bands and the 

 ordinary spots lost, presenting an appearance that proved puzzling until 

 the series now in hand was examined. Secondaries blackish, fringes rufous. 



Expands. — 1.16-1.28 inches = 29-32 mm. 



Habitat. — Kaslo, British Columbia, July and August, Mr. Cockle ; 

 Peachland, B. C, in July, Mr. Wallis, through Dr. Fletcher ; Ainsworth, 

 B. C, in July, Mr. Findlay, also through Dr. Fletcher. 



A series of 12 c^ 's and 12 $ 's, most of them in good or fair con- 

 dition, and while extremely variable, yet in altogether a different direction 

 from trigona, which is approached only in one or two very uniform 

 examples. 



Rhynchag7'otis alcandola^ Sm. 



Ground colour pale luteous-gray. Sides of palpi dark brown. 

 Primaries very uniform in general tint. Basal line barely indicated on 

 costa. T. a. line faintly indicated by scattered black scales^ its course 

 outwardly oblique. T. p. line geminate, consisting rather of venular 

 points connected by black scales, very evenly outcurved over the cell and 

 very slightly incurved below it. The s. t. space is black powdered, 

 deepening to a distinct shade before the pale, slightly irregular s. t. line, 

 which is the most obvious feature of the wing. Small terminal black 

 points in the interspaces, and a pale yellow line at base of fringes. 

 Orbicular irregular, oblique, blackish-filled, with narrow yellow defining 

 line. Reniform large, blackish-filled, with a narrow yellow defining line ; 

 nearly upright, a little drawn in at centre. Secondaries smoky, paler at 

 base. Beneath powdery, with an extramedial dusky line and a discal spot. 



Expands. — 1.40 inches = 35 mm. 



Habitat. — Yavapai Co., Arizona, Oct. 4, Mr. Hutson. 



One female, in fair condition only. Prof. F. FI. Snow has other 

 examples, and I sent him the MSS. name some time since, expecting to 

 get additional material for the description. It is to validate the name sent 

 out that I base the species on a single defective example, knowing that 

 there are other and better ones in collections. 



The species is perhaps nearest to alteniata, but obviously distinct in 

 the course of the s. t. line, the dark s. t. space and in the form of the 

 ordinary spots.
