AMERICAN MOTHS OF THE SUBFAMILY PHYCITENAE 



187 



Genera 91 and 92: Adelperga and Eumysia 



[Venational division A. Forewing with 11 veins; 10 from cell, 

 8 and 9 stalked, 2 and 3 from the cell, 4 and 5 stalked or connate. 

 Hind wing with veins 7 and 8 closely approximate or contiguous; 

 2 from close to lower, outer angle of cell; discocellular vein 

 curved. Harpe of male genitalia with an elongate, strongly 

 sclerotized clasper; gnathos terminating in a stout, short or 

 moderately long, hooked process; transtilla incomplete; vinculum 

 stout, as broad or broader than long.] 



91. Adelperga, new genus 



Type of genus: Heterographis cordubensiella Ragonot. 



Tongue well developed. Antenna simple, pubescent. 

 Labial palpus obliquely upturned, reaching verte.x, 

 third segment short, projected forward. Maxillary 

 palpus squamous. Forewing with vein 2 from or from 

 very near outer angle of ceU; 2 and 3 approximate at 

 base; 4 and 5 stalked; 6 straight from below upper 

 outer angle of cell; 10 from cell, closely approximate to 

 8-9; male without costal fold. Hind wmg with vein 2 

 from very close to angle of cell ; 3 and 5 stalked ; 7 and 8 

 approximate; cell less than half (more than one-third) 

 the length of the wing; discocellular vein curved. 

 Eighth abdominal segment with a pair of short ventro- 

 lateral hair tufts. 



Male genitalia with apical process of gnathos a rather 

 short hook. Uncus broadly and bluntly rounded at 

 apex. Harpe with a decided incurvation between sac- 

 cidus and cucuUus; clasper present, developed as a 

 long, strongly sclerotized and apically curved and 

 swollen arm, projecting into the incurvation between 

 sacculus and cucullus. Anellus semitubular. Aedea- 

 gus long, stout, cleft and strongly sclerotized towards 

 apex; penis armed with a pair of short stout thornlike 

 cornuti and numerous granulations. 



Female genitalia with bursa copulatrix thickened and 

 sclerotized at junction with ductus bursae; signa 

 strongly developed, consisting of two large, opposed 

 plates armed with long, stout spines, a scattering of 

 similar spines between the plates, and a band of shorter 

 spines where ductus and bursa join; ductus bursae 

 short, flattened, very broad and sclerotized throughout; 

 genital opening very large; ductus seminalis from 

 bursa near junction with ductus bursae. 



This genus is easily identified by its genitalia. It 

 shows striking afiinities to Passadena of group I in shape 

 of harpe, with incurvation between sacculus and cuciil- 

 lus, and in the development of an enlarged, strongly 

 sclerotized and projecting clasper. Passadena also has 

 opposed signa similarly spined. 



371. Adelperga cordubenBiella (Ragonot), new combuiation 



Figures 429, 772 



Heterographis cordubensiella Ragonot, Nouv. Gen., p. 30, 1888. 

 Hulstia cordubensiella (Ragonot), Monograph, pt. 2, p. 128, 1901. 



Forewing with color and markings of Euzophera semi- 

 funeralis (especially the pale color form of its synon3an 

 a^izeeZZa Ragonot; see p. 273); the antemedial line far 

 out (at or very near middle of wing), nearly vertical, 

 slightly notched at top of cell and at lower fold, white 



bordered outwardly by a black line; subterminal white 

 line sinuate, incurved at vein 6 and the lower fold, 

 bordered inwardly by black; the two transverse lines 

 rather close (as in typical Euzophera) and the space 

 between them dusted with blackish scales; otherwise 

 the ground color of the wing is ash gray strongly shaded 

 with reddish ocherous, especially in the enlarged basal 

 area; a blackish spot on inner margin near base; a 

 smaller blackish spot on costa just beyond the sub- 

 terminal line and a row of black dots along termen. 

 Hind wing whitish, shading to pale smoky fuscous 

 towards apex and outer margin. Alar expanse, 15-18 

 mm. 



Genitalia with characters as given for the genus. 



Type locality: C6rdoba, Argentina (type in Paris 

 Mus.). 



Food plant: Unknown. 



Distribution: Argentina: Cordoba, Las Vasquez, 

 Tucumdn. 



The figure in the Ragonot Monograph (pi. 22, fig. 20) 

 is misleading. It shows the hind wing much too dark 

 and uniformly colored, and shows none of the strong 

 blackish dusting in the area between the antemedial 

 and subterminal lines. 



92. Genus Eumysia Dyar 



Eumysia Dyar, Ins. Insc. Menstr., vol. 13, p. 220, 1925. (Type 

 of genus: Yosemilia mysiella IJyar.) 



Tongue well developed. Anteima strongly ciliate in 

 male (cilia about three times the width of shaft), simple 

 in female. Labial palpus porrect, long and beaklike 

 (projecting about three times the length of the head 

 beyond it). Maxillary palpus minute, filiform. Fore- 

 wing smooth; 11 veins; vein 2 from before angle of cell; 3 

 from the angle; 4 and 5 very shortly stalked or con- 

 nate; 6 from belowupperangleof cell, straight; 10 from 

 cell, approximate to stalk of 8-9 at base; male without 

 costal fold. Hind wing with vein 2 close to lower outer 

 angle of cell ; 3 and 5 stalked ; 7 and 8 closely approxi- 

 mate or contiguous for some distance from cell; cell 

 slightly less than one-half the length of wing; disco- 

 cellular vein curved. Eighth abdominal segment of 

 male with a pair of short, weak hair tufts. 



Male genitalia with gnathos terminating in an 

 elongate hook. Uncus narrowly and bluntly rounded 

 at apex. Harpe with lower margin evenly curved, no 

 incurvation between sacculus and cucullus; clasper 

 present, developed as a strongly sclerotized, nearly 

 straight hook. Anellus a simple plate. Aedeagus 

 short, straight, moderately slender; penis unarmed. 

 Vinculum broad, short, truncate. 



Female genitalia with bursa and ductus bursae 

 simple; ductus seminalis from middleof ductus bursae. 



The genus was originally erected for nine species 

 which Dyar removed from Zophodia and Yosemitia. 

 As here restricted it includes only three of these (mysi- 

 ella, maidella, and Juscella) , a fourth species (pallidi- 

 pennella), which Dyar had referred from Yosemitia to 

 Zophodia, and a new species from Washington State.
