in the Paris Museum. This latter is the only specimen 

 of the species in the Ragonot Collection. There are no 

 characters of structure or pattern by which elongellum 

 can be separated from albescentellum. 



Type localities: California {albescentellum, in Paris 

 Mus.); Williams, Ariz, (elongellum, in USNM). 



Food plant: Unlcnown. 



Distkibution: California; Arizona, Williams (July), 

 Redington, Santa Catalina Mts.; Colorado, Silverton 

 (July).

 No. 6363, 1939. 



McDunnough's identification (Contributions, vol. 4, 

 pt. 2, p. 174, 1918) of the true type of this species in the 

 Rutgers Collection is without any doubt the correct 

 one. The specimen is a male without abdomen, 

 labeled Nevada, "3838." It also bears a Hulst name 

 label "Homoeosoma uncanale," which is obviously in- 

 correct and can be ignored as an error in labeling. The 

 Nevada specimen is one of the well-marked examples 

 of the species and agrees with the original description. 



The markings are variable in the extreme, ranging 

 from pure white examples with only a couple of small 

 blackish discal dots at end of cell and a row of faint 

 blackish dots along termen to white examples with a 

 broad, slanting, blackish, antemedial band and a narrow 

 blackish subterminal band. On the right side of one 

 specimen before me from Manitoba the blackish bands 

 are fused, filling the entire center of the wing. The 

 specimens without transverse markings are superficially 

 like those of illuviellum, usually showing the discal spot 

 at upper outer angle of cell a trifle stronger but other- 

 wise only separable on genitalia. The two figures in 

 the Ragonot Monograph (pi. 33, figs. 7, 18) are good 

 illustrations of the normal variation in pattern. Alar 

 expanse, 23-34 mm. 



Type locality: Nevada (type in AMNH, ex 

 Rutgers) . 



Food plant: Unknown. 



Distribution: United States: Arizona; Nevada; 

 Colorado; Utah, Stockton (June, July); California, 

 Davis Creek, Modoc County (June) ; Washington, 

 Pullman (Aug.), Walla Walla (June). Canada: Mani-

Homoeosoma inornatellum (Hulst), McDunnough, Check list. 

 No. 6369, 1939. 



A very faintly marked species, especially in the male; 

 forewing pale gray or grayish fuscous with a faint, white 

 subcostal streak (much as in electellum) ; antemedial 

 markings consisting of one or two obscure dark dots; 

 discal dots at end of cell faint. In the female the 

 markings are somewhat stronger. Hind wings pale 

 smoky fuscous. Superficially the males look much like 

 some examples of electellum, but the two species are 

 easily separated on structure. In addition to the 

 differences in male genitalia and the eighth abdominal 

 segment, inomatellum has veins 2 and 3 of forewiag 

 approximate at origin whUe in electellum these veins are 

 well separated, about as far apart as 3 and 4. Alar 

 expanse 23-25 mm. 



From other species with simple vinculi {albescentellum, 

 impressale, deceptorium) , inornatellum is readily dis- 

 tinguished by the shape of the harpe and the apical 

 process of gnathos. The signum of the female is 

 situated very near the anterior end of the bursa, as in 

 electellum. Dyar's identification of the type of inoma- 

 tellum with stypticellum is an obvious error. The two 

 species are not even superficially similar. 



Type locality: Anglesea, N. J. (type in AMNH, ex 

 Rutgers) . 



Food plant: Unknown. 



Distribution: New Jersey, Anglesea (May, June); 

 Pennsylvania, Mount Airy. 



A series of males from the type locality is in the 

 National Collection. 



453. Homoeosoma deceptorium, new species 

 Figures 488, 985 



Color and markings as in the larger, most strongly 

 marked specimens of stypticellum, except that the white 

 dusting on forewing is more restricted to the costal half 

 of the Aving ; transverse antemedial band broad, slanting, 

 not appreciably angulate, blackish brown; subterminal 

 dark band narrower but distinct; discal spots at outer 

 angles of cell distinct. Hind wings pale smoky fuscous 

 with veins outUned by darker scaling. Alar expanse 

 23-27 mm. 



Male genitalia chiefly distinguished from those of 

 other associated species in this subgroup by the shape 

 of the apical process of gnathos. Signum of female 

 located near middle of bursa. 



Type locality: New Brighton, Pa. (type in USNM, 

 61373; paratypes in Canadian Nat. Coll.). 



Food plant: Unknown. 



Described from male type and four male and one 

 female paratypes from the type locality (July, Aug.) ; 

 one male and one female paratype from Alcove, Quebec 

 (July 7, 1936, F. A. Urquart).
