AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



139 



Distribution: United States; California (Southern 

 California without more definite locaUty, the tjrpe 

 series), Clarksville (El Dorado County, June); Washing- 

 ton, Pullman; New Mexico, Fort Wingate (July). 

 Canada: British Columbia, Departure Bay (Aug.), 

 Duncans (Vancouver Isl., July), Nicola (July), Welling- 

 ton (June). Also one male without state locality 

 labeled "Larima Co. [sic], Aug., 1901, Schaus collector." 



The species is distinct and easily distinguished from 

 brv^ei on the color and pattern of forewing, especially 

 by the broad black band extending from inner margin 

 to costa before the antemedial line and by the shallow 

 indentation of the subterminal line below costa.

 1887. — Barnes and McDunnough, Contributions, vol. 3,

Nephopteryx rhypodella Ragonot (not Hulst), Monograph, pt. 1, 

 p. 270, 1893. 



Forewing ashy bluish gray; the transverse lines com- 

 plete, narrow, white, obscure except on the well-marked 

 darker examples, indicated chiefly by the fine, black 

 outer border of the antemedial line and similar black 

 inner border of the subterminal line ; preceding the ante- 

 medial line a quadrate blackish spot on inner margin; 

 limited above by a weak, smaller, pale, somewhat oliva- 

 ceous shade in the lower fold, this pale shade not 

 interrupting the antemedial line itself; indentations of 

 subterminal line as in junerellus; discal dots obscure, 

 the lower one sometimes distinct (under magnification) 

 and frequently with a dark shade below it which forms 

 a round dark spot, to the naked eye one of the more 

 conspicuous markings on the wing; a row of more or 

 less confluent black dots along termen. Hind wing 

 translucent, whitish with a smoky shade towards apex; 

 the veins darkened; a fine brown line along termen. 

 Alar expanse, 26-30 mm. 



Male genitalia with cornutus of the same length as 

 that of brucei and funerellus but somewhat stouter. 

 GenitaUa otherwise like those of the species following 

 (incertus). Female genitalia with bursa very long, and 

 narrow throughout its length, but little wider than the 

 ductus bursae. 



Type locality: America Septentrionalis (type in 

 Paris Mus.). 



Food plant: Unknown. 



Distribution: California, Loma Linda (June, July), 

 Los Angeles County (1,060 ft., Jime), Monachee 

 Meadows (Tulare County, July), Mount Lowe (July), 

 San Gabriel Mts. (1,700 ft., July); Arizona, Nogales 

 (May), Santa Rita Mts. (May); Utah, Bellevue 

 (Washington County, May, June); Colorado, Silverton 

 (July). 



The spurious type of Telethusia rhypodella (Hulst) 

 in the Rutgers Collection belongs here. It is discussed 

 under the treatment of rhypodella (p. 137). 



283. Phobu9 incertus, new species 

 Figures 356, 846 



Color and markings of forewing as in curvatellus 

 except duller, lacking the bluish tint of the latter 

 species; the quadrate dark spot preceding the ante- 

 medial line also continued as a broad band to costa, 

 though frequently interrupted by a pale shading at 

 lower fold. 



Male genitalia with cornutus appreciably stouter and 

 longer than that of any of the other species of the genus. 

 Bursa copulatrix of the female genitalia less than half 

 the length of that of curvatellus but twice the length of 

 that of brucei or funerellus. 



Type locality: Strawberry Valley (6,000 ft.), San 

 Jacinto Mts., Calif, (type in USNM, 61348). 



Described from male type and five male and five 

 female paratypes from the type locality, collected by F. 

 Grinnell, Jr., June 16, 17, and 18, 1908. 



Except for the genitalic differences this might easily 

 be a higher altitude race of curvatellus, but the differ- 

 ences in size of cornutus and length of bursa seem to 

 be constant characters and greater than to be expected 

 in variants of one species. 



74. Actrix, new genus 



Type of genus: Tacoma nyssaecolella Dyar. 



Tongue well developed. Antenna weakly pubescent; 

 on male with sinus and scale tuft in base of shaft. 

 Labial palpus upcurved, slender, reaching above vertex; 

 second segment somewhat flattened and very slightly 

 rough scaled, not grooved on male ; third segment about 

 two-thirds the length of second, acuminate. Maxillary 

 palpus squamous. Forewing smooth; 11 veins; vein 2 

 from near lower outer angle of cell; 3 from the angle, 

 approximately equidistant from 2 and 4 at base; 4 and 

 5 shortly stalked; 6 from below upper angle of cell, 

 straight; 8 and 9 very long stalked; 10 from the cell, 

 approximate to the stalk of 8-9 for some distance; male 

 without costal fold. Hind wing with vein 2 from before 

 but near lower outer angle of cell; 3 from the angle, 

 connate or (on occasional specimens) shortly fused 

 with the stalk of 4-5 ; 4 and 5 stalked for two-thirds of 

 their lengths; 7 and 8 strongly anastomosed beyond 

 cell for half or a trifle more than half their lengths; 

 cell slightly less than half the length of wing; dis- 

 cocellular vein curved, extended outwardly at lower 

 angle of cell. Eighth abdominal segment of male with 

 pair of ventrolateral hair tufts. 



Male genitalia with uncus broader than long, its 

 outer lateral angles slightly lobed. Apical process of 

 gnathos broad, shieldhke, its lateral arms greatly 

 reduced. Transtilla absent. Harpe without clasper. 

 Aedeagus straight, divided towards apex, the projecting 

 divided elements strongly sclerotized; penis with some 

 very weak scobinations, but otherwise imarmed. 

 Vinculum short, stout, about as long as greatest width, 

 evenly rounded to blunt terminal margin.
