AMERICAN MOTHS OF THE SUBFAIVULY PHYCITESTAE 



221 



Distinguished from other species with the electellum 

 type of genitalia by the broad, transverse, antemedial 

 dark brown band and the more or less extended dark 

 shading on inner margin of subterminal line of forewing, 

 this latter dark shading sometimes extending to the 

 dark discal spots at outer margin of cell. Hind wings 

 smoky fuscous. Alar expanse, 18-25 mm. 



I agree with McDunnough that the female from 

 Colorado in the Hulst Collection which McDunnough 

 has so labeled is the probable type of uncanale. The 

 differences shown in figure 976 between it and the 

 signum of typical eastern stypticellum are only individual 

 in character and no more than those exhibited by other 

 eastern examples of stypticellum. I find nothing on 

 which to distinguish uncanale, even as a western race, 

 from stypticellum. 



Type localities: Maine (stypticellum, in BM [?]); 

 Custer County, Colo, (uncanale, in AMNH, ex Rutgers) . 



Food plant: Cirsium, Bhus. 



Distribution: United States: Maine, Orono, Bar 

 Harbor (July) , Wales (July) ; Massachusetts, Martha's 

 Vineyard (July, Aug.); Connecticut, East River (July, 

 Aug.); Rhode Island, Weekapaug (July, Aug.); New 

 York, Eion (June) ; Pennsylvania, Oak Station (Mar.) , 

 New Brighton (July); Illinois, Palos Park (Aug.); 

 Arkansas, Washington County (July); Texas; Colorado, 

 Custer County, Glenwood Springs (Aug.), Logan's 

 Peak (July) . Canada: Quebec, St. Hilaire (July) ; 

 Ontario, Ottawa (June), Trenton (June); Manitoba, 

 Aweme (June, July), Rounthwaite (Aug.); Saskatch- 

 ewan, Regina (July). 



Among the foregoing, one example (from Palos Park, 

 111., Aug. 6, 1939) was reared by A. K. Wyatt from 

 larvae feeding in the flower heads of "swamp thistle." 



443. Homoeoeoma striatellum Dyar 



FiGURi 977 



Homoeosoma striatellum Dyar, Proc. Ent. Soc. Washington, vol. 7, 

 p. 38, 1905.— McDunnough, Check list. No. 6367, 1939. 



Pale slate gray; the veins of forewing outlined by 

 blackish scaling, transverse lines nearly obsolete, in 

 some specimens indicated- by a narrow, dark, angulate, 

 antemedial band and some dark shading towards costa 

 on inner side of subterminal oblique line; discal spots 

 faintly indicated or absent. Hind wings whitish to very 

 pale smoky fuscous. Signum of female somewhat vari- 

 able, the extent of variation shown in the figure. Alar 

 expanse, 18-23 mm. 



Type locality: Phoenix, Ariz, (type in USNM). 



Food plant: Unknown. 



Distribution: Arizona, Baboquivari Mts., Ajo, 

 Pima County (Mar.), PhoenLx (Mar., Apr.), Tempe 

 (Feb.); California, Death Valley (Apr.). 



444. Homoeosoma oslurellura Dyar

Homoeosoma oslarellum Dyar, Proc. Ent. Soc. Washington, vol. 7, 

 p. 38, 1905.— McDunnough, Check list, No. 6373, 1939. 



Dark grayish fuscous with a scattering of whitish 

 scales along costa of forewing; transverse marking obso- 



lete. Hind wing pale smoky fuscous. Alar expanse, 

 17-23 mm. 



Female genitalia with signum similar to that of 

 striatellum, considerably larger than that of either 

 stypticellum or electellum, situated somewhat nearer the 

 middle of the bursa. 



Type locality: Chimney Gulch, Golden, Colo, 

 (type in USNM). 



Food plant: Unknown. 



Distribution: Colorado, Golden ;iVew Mexico, Beulah 

 (July); California, San Francisco (Apr.). 



445. Homoeosoma oslarellum breviplicitum, new race 



A Southern California race differing from typical 

 oslarellum by the much shorter roll of sclerotized wrink- 

 lings of penis (but half the length of that in oslarellum 

 or the other preceding species), its paler wing color and 

 forewing markings. Color of forewing slate gray (iuter- 

 mediate between that of oslarellum and striatellum); a 

 faint but distinguishable and sharply angulate, narrow, 

 dark, antemedial band; veins more or less outlined by 

 blackish scaling, especially in outer area of wing; hind 

 wing more whitish and with the veins more darkly con- 

 trasted than in typical oslarellum. Alar expanse, 20-25 

 mm. 



Type locality: San Diego, Calif, (type in USNM, 

 61370). 



Food plant: Unknown. 



Described from male type and male paratype from 

 the type locality (May 3, 1924, H. G. Dyar) ; one female 

 paratype from San Diego (Jime 14, 1924, J. M. Dam- 

 mers) and three female paratypes from Riverside, 

 Calif. (Apr. 14 and 17, 1937, Grace B. and John L. 

 Sperry).

White with a faint scattering of dark scales on fore- 

 wing; transverse lines obsolete, their usual position 

 indicated only by a couple of dark dots in the ante- 

 medial and a very faint transverse shading of dark dust- 

 ing in the subterminal areas; costal edge dark beyond 

 middle; a small but rather conspicuous dark dot at 

 lower outer angle of cell and a much smaller, more 

 obscure dot at upper outer angle. Hind wings pale 

 smoky fuscous ; cilia white. Alar expanse, 22-28 mm. 



Male genitalia with apical process of gnathos stouter 

 and with less deeply concave lateral margins than in 

 the preceding species; vinculum not produced dorso- 

 laterally. 



Type localities: Sonora, Mexico (illumellum, in 

 Paris Mus.); Arizona (candidellum, in AMNH, ex 

 Rutgers). 



Food plant: Unknown.
