AMERICAN MOTHS OF THE SUBFAMILY PHYCITDSTAE 



105 



Forewing dark gi'ay shading into very dark gi-ayish 

 or blackish brown towards the white costal streak; the 

 latter ending just before apex; no spottings or other 

 markings on the wing, even the lower discal dot lost in 

 the dark suffusion of the wing. Hind wing whitish 

 at base, shading into a smoky outer area. Alar expanse, 

 26-34 mm. 



Male genitalia with apex of costa of harpe narrow, 

 very slightly notched, reaching only to end of cucullus. 

 Harpe itself shorter in proportion to length of tegumen 

 and uncus than that of any preceding species except 

 boisduvaliella. Cornuti spaced apart as in fosterella, 

 the longer one about one-third the length of aedeagus. 



Female genitalia with two rather large, irregularly 

 shaped, pitted and sclerotized patches in bursa, one at 

 the terminal end, the other on the left side (viewed 

 ventrally); bursa otherwise membranous except for a 

 sclerotization about junction with ductus bursae; 

 ductus bursae not produced at genital opening, its 

 apical margin straight. 



Type locality: California (type in AMNH, ex 

 Rutgers) . 



Food plant: Unknown. 



Distribution: California, Claremont, "En route Im- 

 perial to Bishop" (May), Loma Linda (Mar.), River- 

 side (Apr.), Shasta Retreat (Siskiyou County, July); 

 Washington, Olympia (June), Rochester (June), Seattle, 

 Wenatchee (May). McDunnough also records the spe- 

 cies from Lethbridge, Alberta, Canada. His specimen 

 is undoubtedly this species, but may represent one of 

 the varieties that follow. 



The type in the Rutgers Collection lacks antennae 

 and abdomen but matches otherwise the examples in 

 the National Collection, so there can be no question of 

 the application of Hulst's name. He emended its spell- 

 ing to albocostalis in 1890, but gave no reason for doing 

 so, hence we shall probably have to perpetuate the 

 original barbarous spelling. 



215. Pima albocostalialis subcostella (Bagouot), new combination 



Epischnia subcostella Ragonot, N. Amer. Phycitidae, p. 10, 1887; 

 Monograph, pt. 1, p. 520, 1893. — McDunnough, Check list, 

 No. 6255, 1939. 



Forewing with white costal streak as in tj^jical albo- 

 costalialis; below it a bordering band of blackish brown 

 with a lighter brown shade below it as far as lower fold; 

 these dark shades terminating beyond cell in what would 

 be the position of the antemedial line if one were pres- 

 ent, the outer margin of the dark shade outwardly 

 angled at middle; remainder of wing pale, ashy gray 

 with a dusting of blackish scales along outer two-thirds 

 of inner margin and (in some specimens) blackish 

 streaklets on the veins before termen; on basal third of 

 vein lb a white dot preceded by a black shade. Hind 

 wing white; smoky shading limited to a narrow line 

 along termen and a very small area at apex; on the fe- 

 males the smoky tints slightly more extended. Alar 

 expanse, 25-27 mm. 



Genitalia, male and female, as in typical albocostal- 

 ialis. 



Type locality: Utah (type in Paris Mus.). 



Food plant: Unknown. 



A male and three females from Eureka, Utah (May, 

 June), a female from Bellevue, Washington County, 

 Utah (May) and a male from Pyramid Lake, Nev., are 

 before me. They match Ragonot's description and 

 figure of subcostella in every detail. The name may 

 represent nothing more than a color variety of albo- 

 costalialis and if there were not an old name available 

 for it, and one that until now was supposed to repre- 

 sent a distinct species, I should not have named it. I 

 am holding subcostella as a trinomial against the possi- 

 bility that it may represent a valid local race. 



There are also before me what appear to be two 

 other varieties with male genitalia identical to those of 

 albocostalialis: 



Variety a: A large form with a reddish brown band 

 bordering the white costal stripe; the red-brown color 

 shading into ocherous fawn on lower and outer areas 

 of the wing; lower discal dot present, black; no white 

 spot or other appreciable marking on vein lb. Hind 

 wing ocherous white with a pale broken Une along ter- 

 men. Alar expanse, 34-35. Represented by three 

 males from Manitou, Colorado (H. G. Dyar, coll. No. 

 6062-6065, May 5, 1891). 



Variety b: A variable variety ranging from dark gray, 

 suffused examples to a couple with the entire median 

 area of the forewing a ruddy fawn color; the white spot 

 is present on vein lb, but very faint on the darker 

 specimens. Hind wings white to pale smoky fuscous. 

 Alar expanse, 26-27 mm. 



The female genitalia differ rather markedly from 

 those of subcostella or typical albocostalialis in that the 

 sclerotized patches in bursa are situated on opposite 

 sides of that organ. This arrangement is consistent for 

 the females from both New Mexico and Arizona. 



Distribution: Colorado, Glenwood Springs (June); 

 New Mexico, Fort Wingate (June) , Pecos (June) ; Ari- 

 zona, Huachuca Mts., White Mts. (Aug.). 



Superficially this foi'm looks hke nothing but a color 

 variant of subcostella. However, if the single female 

 genitalic difference should hold through extended series 

 it will need further designation. 



216. Pima fulvinigella (Ragonot), new combination 



Figure 304 



Epischnia fulvirugella Ragonot, N. Amer. Phycitidae, p. 10, 

 1887; Monograph pt. 1, p. 521, 1893.— McDunnough, Check 

 list. No. 6253, 1939. 



I have seen nothing that exactly matches Ragonot's 

 description or figure (Monograph, pi. 16, fig. 43). A 

 male before me from San Francisco has a similar, at- 

 tenuated white subcostal streak and rather pronounced 

 black lining on the veins from cell. Its genitalia, how- 

 ever, do not match those of the type, and the moth 

 itself is smaller (27 mm.). Ragonot gives the alar 

 expanse of his type as 30 mm. 



Type locality: California (type in Paris Mus.). 



Food plant: Unkno\vn.
