AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



189 



Hind wing smoky fuscous; cUia slightly paler, with a 

 whitish median band. Alar expanse, 30 mm. 



Type locality: Yakima, Wash, (type in USNM, 

 61364). 



Food plant: Unknown. 



Described from female type and one female paratype 

 from the type locality, collected by A. Rolfs, May 20, 

 1932, and received from J. F. G. Clarke under his Nos. 

 4008 and 4009. 



A large, dark species. It may eventually prove to be 

 only an extremely dark color form or race of maidella, 

 but superficially it is so different in color and so unlike 

 any other described species in the genus that a separate 

 specific designation seems warranted. 



Genus 93: Divitiaca 



(Venational division D. Forewing with 10 veins; 10 from cell, 

 8 and 9 stalked; 4 and 5 united; 2 and 3 from the cell. Hind 

 wing with 7 and 8 approximate ; 2 from close to lower outer angle 

 of cell; discocellular vein curved. Labial palpi porrect. Male 

 genitalia with uncus triangulate, tapering evenly to rounded or 

 bluntly pointed extremity, large in proportion to reduced 

 tegumen; transtilla incomplete; harpe with a transverse sclero- 

 tized ridge from base of costa to lower angle of cucuUus; penis 

 without cornuti or other appreciable sclerotizations; vinculum 

 broad, stout, short. Female genitalia with ductus seminalis 

 from ductus bursae.] 



93. Genus Divitiaca Barnes and McDunnough 



Divitiaca Barnes and McDunnough, Contributions, vol. 2, p. 183, 

 1913. (Type of genus: Divitiaca ochrella Barnes and 

 McDunnough.) 



Tongue well developed. Antenna pubescent; in 

 male a shallow sinus and slight scale tuft at base of 

 shaft; in female simple. Labial palpus porrect; long, 

 extending over twice the length of the head beyond it ; 

 broadly scaled; third segment about half the length of 

 second. Maxillary palpus minute, filiform. Forewing 

 smooth; 10 veins; vein 2 from slightly before angle of 

 cell; 3 from angle; 4 and 5 united; 6 from below upper 

 angle of cell, straight; 10 from cell, separated from the 

 stalk of 8-9; male without costal fold. Hind wing 

 with vein 2 from very close to angle of cell; 3 and 5 

 stalked; 7 and 8 closely approximate for some distance 

 from cell; cell slightly less than one-half the length of 

 the wing; discocellular vein curved. Eighth abdominal 

 segment of male with a pair of short ventrolateral hair 

 tufts and a lateral pair of eversible lobes with long hair 

 tufts 



Male genitalia with apical process of gnathos a stout 

 hook. Harpe with broadened cucullus, its outer 

 margin straight and vertical or slightly roimded; a 

 transverse sclerotized ridge extending from base of costa 

 to lower angle of cucullus. Anellus a slightly ciirved 

 plate with short lateral lobes. Aedeagus short, slender, 

 needlelike; penis without armature. Vinculum short, 

 extremity narrowly rounded. 



Female genitalia with bursa and ductus bursae mem- 

 branous; bursa large, sausage shaped or trilobed (twice 



constricted near junction with ductus bursae), without 

 signum ; ductus bursae long, very slender, with or with- 

 out a few fine spines at junction with bursa; ductus 

 seminalis from ductus bursae nearer to biu-sa than to 

 genital opening. 



This genus is closely related to Macrorrhinia and 

 Ocala, agreeing with them in genitalic and most other 

 structural characters except for the absence of vein 4 of 

 forewing, a consistent character for all the species and 

 specimens of the genus. 



377. Divitiaca ochrella Barnes and McDunnough

Divitiaca ochrella Barnes and McDunnough, Contributions, vol. 

 2, p. 183, 1913.— McDunnough, Check list, No. 6357, 1939. 



Forewing pale ocherous; veins faintly outlined, 

 whitish; antemedial line indicated by an outwardly 

 curved and slanting row of blackish spots; between this 

 and base of wing, above inner margin, a small, more or 

 less diffused, blackish spot; sub terminal line faintly 

 indicated by a broken series of blackish streaks or spots 

 on the veins; a dark discal spot at lower outer angle of 

 cell, the discal spot at upper outer angle very faint or 

 absent. Hind wing semihyaline, whitish. Alar ex- 

 panse, 12-17 mm. 



Male genitalia with apical process of gnathos a 

 moderately long, stout, slightly curved and evenly 

 tapering hook. Female genitalia with ductus bursae 

 weakly spined at junction with bursa copulatrix; bursa 

 sausage-shaped, in part minutely scobinate. 



Type locality: Everglade, Fla. (Apr., type in 

 USNM). 



Food plant: Unknown. 



Known only from the type series and one other male 

 from the tj^e locaUty, and one male from Marco, Fla., 

 all in the National Collection. 



378. Divitiaca simulella Barnes and McDunnough 



Divitiaca simulella Barnes and McDunnough, Contributions, 

 vol. 2, p. 183, 1913.— McDunnough, Check list. No. 6356, 

 1939. 



Similar to ochrella, differing only in its smaller average 

 size, and somewhat darker fore and hind wings. The 

 hind wing is a pale smoky hyaline hue. Alar expanse, 

 12-14 mm. 



The male genitalia of the type are a trifle smaller than 

 those of the type of ochrella and the apex of uncus 

 seems slightly more pointed; but these are scarcely 

 more than individual differences. The female genitalia 

 are essentially like those of ochrella. 



Type locality: Everglade, Fla. (Apr., type in 

 USNM). 



Food plant: Unknown. 



Represented in the National Collection by the type 

 series and one other male from the Everglades. Very 

 doubtfully distinct from ochrella. In a reared series the 

 color differences would probably disappear and speci- 

 mens reared under moist conditions would show more
