PSYCHE. 



[October 1892. 



of the red color to the wings. It differs 

 from Thomas's description in that the 

 "dorsal area" (axillary field) of the 

 tegmina is not without spots, though 

 such specimens do occur, especially in 

 the $ . As his description is very in- 

 sufficient and his remarks on its rela- 

 tionship misleading, I have printed 

 here the description drawn up from my 

 specimens before I had seen his type. 

 I had formerly supposed his species to 

 be a synonym of H. (ff.) haldemanii. 

 Glover's figure (pi. iS, fig. 14), pre- 

 sumablv from specimens furnished by 

 Thomas, is pretty certainly that species. 

 It does not at all agree with the present 

 species. 



The distribution of the species as given 

 above must therefore be slightly ex- 

 tended. Thomas's original specimens 

 were found from Ogden to Smithfield 

 in Cache Valley, northern Utah ; and 

 he subsequently adds southeast Idaho. 



HlPPISCUS (X.) AFFR1CTUS Sp. IIOV. 



Very dark brownish fuscous, of robust 

 form and medium size, the sexes varying con- 

 siderably. Head dark on summit but else- 

 where mottled with pale cinereous and light 

 brownish fuscous, the summit moderately 

 broad and tumid, gently rugulose, the toler- 

 ably smooth-floored vertical fastigium open 

 behind or with the lateral walls incurved 

 somewhat, open also in front to the large 

 and rather deep biareolate median foveola; 

 lateral foveolae very small subcircular, the 

 lower walls obscure ; frontal carina of mod- 

 erate width, deeply sulcate throughout, 

 though the sulcus fades at base, consid- 

 erably narrowed at summit, more or less ex- 

 panding at base, at least in the $. Pro- 



notum expanding but moderately behind, 

 the process variable but generally slightly 

 less than rectangulate, the dorsum broadly 

 edged laterally with an oblique, broad, 

 usually posteriorly narrowing, pallid cinere- 

 ous band; margin of process edged with 

 testaceous; lateral lobes of prozona cinere- 

 ous flecked with brown and with a large 

 median oblique dark brown spot; metazona 

 more or less but not greatly tumid centrally, 

 the median carina arched, distinct and sharp, 

 not elevated , and equal; lateral carinae dis- 

 tinct and sharp, longer than usual and cen- 

 trally elevated; dorsal surface of metazona 

 arenaceo-rugulose but not very heavily mar- 

 ked. Tegmina cinereous and brownish fus- 

 cous, the latter in more or less transverse 

 broad belts but all, as in the next species, 

 somewhat confused and blurred, giving it a 

 more maculate appearance than usual, the 

 cinereous markings prevailing along the 

 costal third of the wing, where also the 

 darker markings are usually darkest; a 

 broad and rather bright flavo-testaceous 

 sutural stripe. Wings pale citron, rarely sal- 

 mon-red at base, the reticulation the same, 

 vitreous with black reticulation at apex, with 

 occasionally a cellular spot or two and a 

 broad or rather broad, arcuate, median, black- 

 ish or very dark fuliginous band, gently nar- 

 rowing toward the anal angle which it just 

 reaches, not at all or but slightly narrowing 

 above and separated by a generally fine yel- 

 low line from the humeral vitta, which 

 reaches to or nearly to its outer margin and 

 usually extends almost to the base, the costal 

 margin of the basal color (generally a little 

 dulled) interrupted with blackish at the ex- 

 tremity of the vitta. Hind femora and tibiae 

 as in H. (JC.) devotus.
