AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE

cited above. Old World synonymns and doubtful 

 American references are omitted from the foregoing 

 literature citations. There can be no reasonable doubt 

 of the correctness of the European synonymy oifarrella 

 (Curtis) or lajauriella (Constant) (their references will 

 be found in the Ragonot Monograph); but the status 

 of the supposed Asiatic variety tabulella Staudinger is 

 doubtful. Ragonot's reference of albocostalialis Hulst 

 as a variety of boisduvaliella is obviously incorrect. 



In size boisduvaliella averages appreciably smaller 

 than any other species of Pima. Occasional examples 

 have an expanse equal to that of small specimens of some 

 of our American species (24-25 mm.) ; but most speci- 

 mens expand 24 mm. or less, while in the other species 

 the average expanse is well over 25 mm. 



The male genitaha are similar in all essential charac- 

 ters to those of albiplagiatella.; but the female genitaha, 

 while of the same general habitus, differ in marked and 

 apparently consistent details — the folds of the bursa are 

 more weakly sclerotized, the bursa itself decidedly 

 smaller, and the granulations and scobinations in bursa 

 weaker. The contrasts are somewhat greater than 

 shown in the figures.

Check list, No. 6251, 1939. 



Larger than boisduvaliella. The ground color on lower 

 half of foremng very pale fawn, paler than that of 

 boisduvaliella and containing httle of no dark scaling, 

 the latter when present confined to a couple of faint 

 gray dots on basal third of vein lb and some very 

 sparse gray scaling along irmer margin near tornus; the 

 contrasted dark band bordering lower margin of the 

 white costal stripe brown rather than ruddy; a similar, 

 weaker, narrower, brown shade along lower fold for 

 most of its length; extreme costal edgepale brownish 

 gray, this color encroaching on the white stripe beyond 

 middle as in other species; lower discal dot distinguish- 

 able but very faint. Hind wing whitish ocherou's. Alar 

 expanse, 26-31 mm. 



Male genitalia like those of boisduvaliella. Female 

 genitaha similar to those of boisduvaliella but con- 

 sistently different in minor details. These differences 

 were noted in the discussion of boisduvaliella and are 

 shown in the figiires. 



Type locality: New Hampshire (type in MCZ). 



Food plant: Laihyrus maritima and presumably 

 other Leguminosae. 



Distribution: United States: New Hampshire, 

 Hampton (June, July). Canada: Nova Scotia, White 

 Point Beach (Queens County, July). 



Typical albiplagiatella is probably generally distrib- 

 uted in eastern Canada and northeastern United States. 

 The foregoing records are from specimens whose 

 genitaha I have been able to examine, the Nova Scotia 



record from a specimen suppUed by McDunnough. He 

 has referred albiplagiatella as a race of boisduvaliella. It 

 is indeed very close to the European species, but I 

 beUeve the differences in female genitaha justify more 

 than racial separation. 



211. Pima albiplagiatella occidentalis, new race 

 FlGUBE 303 



A variety occurring in the Rocky Mountain and 

 Pacific Coast States. Extremely variable in color and 

 the amount of blackish dusting on forewing. Average 

 specimens in Washington, Colorado, and New Mexico 

 with ground color very pale fawn (cream white in some 

 specimens) ; the dark border of the white costal stripe 

 ranging from pale ocherous brown to dark gray-brown; 

 two distinct black dots on basal third of vein lb, enclos- 

 ing a white spot; the remainder of lb more or less 

 streaked with black outwardly and a fijie peppering of 

 black scales and white scales along inner margin near 

 tornus; costal edge brownish or blackish gray, encroach- 

 ing on and attenuating the white costal streak beyond 

 middle, and sometimes blotting it out before apex. In 

 southern California the paler specimens show more 

 blackish dusting expecially along the outer veins, and 

 sometimes a faint white subterminal line can be dis- 

 tinguished; the darkest specimens are almost a uniform 

 dark gray with the blackish gray dusting obliterating 

 all markings except the white spot on vein lb and the 

 contrasted white costal streak; between these two ex- 

 tremes there is every intergrade in series from any given 

 locality; lower discal spot small, but usually distinct, 

 blackish. Hind wings ocherous white to dark smoky 

 gray. Alar expanse, 24-31 mm. 



Male genitalia like those of typical albiplagiatella 

 except that apex of sclerotized costa of harpe is some- 

 what more swollen; in average specimens the outer 

 edge of apex is slightly concaved; one example from 

 Alamogordo, N. Mex., has the edge almost straight, 

 but there is a gradual intergradation from this to forms 

 with the apex as in our figure of albiplagiatella (fig. 

 305c). The cornuti are like those of typical albiplagia- 

 tella. The female genitalia are like those of eastern 

 albiplagiatella. A series of 24 preparations from the 

 various western localities exhibits no significant varia- 

 tion from type and nothing approaching the bursa of 

 boisduvaliella.
