squamous. Forewing smooth; 11 veins; vein 2 from 

 before the lower outer angle of cell; 3 from the angle, 

 separated from 4-5; 4 and 5 shortly stalked or weakly 

 anastomosed for less than half their lengths from cell; 

 6 from below upper angle of cell, slightly bent at base; 

 8 and 9 stalked for over half their lengths; 10 from the 

 cell, connate or closely anastomosed at base with the 

 stalk of 8-9. Hind wing with vein 2 from well before 

 lower outer angle of cell; 3 from the angle, long; 4 and 5 

 stalked for about four-fifths of their lengths; 7 and 8 

 anastomosed for three-fourths of their lengths; cell 

 short, one-third the length of wing; discoceUular vein 

 vertical, straight. Eighth abdominal segment of male 

 with compound ventral scale tufts. 



Male genitaUa with uncus subtriangulate and with 

 blunt, moderately broad, notched apical margin. Apical 

 process of gnathos a moderately stout hook with a 

 slender, digitate basal projection. TranstUIa absent. 

 Harpe with costa sclerotized throughout, but not 

 produced at apex; cucullus simple, curved, apex 

 bluntly pointed; clasper present, simple, erect, digitate. 

 Penis armed with two moderately stout cornuti, about 

 one-third as long as aedeagus. Vinculiun about twice 

 as long as broad, evenly tapering to its truncate, 

 strongly sclerotized, anterior margin. Vinculum U- 

 shaped with somewhat enlarged base. 



Female genitalia with bursa elongate, narrow, signum 

 absent, two or three deep, convolute sclerotized folds 

 at posterior half, the sclerotization extending for a 

 short distance into ductus bursae; genital opening 

 simple. Ductus seminalis from bursa, near junction of 

 bursa and ductus bursae. 



The genus is easily distinguished by its hind wing 

 venation and genitalia. The male genitalia indicate 

 a close relationship to the Nephopteryx group of genera. 

 However the characteristic hair brush on the harpe of 

 the latter are absent from Homoeographa. It contains 

 only one known tropical American species,

Forewing gray heavUy dusted with white on costal 

 half; antemedial line indicated by a narrow, white, in- 

 wardly notched liae between cell and inner margin and 

 above that by its incompleted outer border, a black 

 line obhque from costa to cell thence inwardly angled to 

 lower vein of cell; sub terminal line faint, sinuate, in- 

 dicated chiefly by blackish gray bordering streaks from 

 costa, the inner one the longer and continued as a weak 

 blaclash shading to inner margin; discal dots small, 

 separated, blackish gray; in outer area black streaklets 

 bordering vein lb above and veins 3 and 6 below. 

 Hind wing semi translucent smoky white; the veins 

 sUghtly darkened and a narrow dark line along termen. 

 Head ashy white. Alar expanse, 21 mm. 



Female genitalic characters as given for the genus.

 National d'Histoire NatureUe, Paris, and the British 

 Museum. 



Genera 72-76: Telethusia to Pyla 



[Venational division B. Veins 4 and 5 of forewing usually 

 separated at base (shortly stalked in Actrix); 10 from the cell, 

 separated at base from stalk of 8-9. Hind wing with cell less 

 than half the length of wing (about one-thid in Pyla). Antenna 

 of male with sinus and scale tuft in base of shaft. Labial palpus 

 oblique or upturned. Maxillary palpus various (minute, 

 squamous or aigrettelike). Male genitalia with transtilla 

 usually absent, if present (Phobus, Stylopalpia) incomplete or 

 its median area very weakly sclerotized; harpe with sclerotized 

 costa sometimes produced at base, never at apex; clasper absent 

 or more or less developed (strongly so in many species of Pyla) ; 

 aedeagus frequently divided (bifid) or spined; penis unarmed or 

 finely scobinate or finely and weakly spined, rarely (Phobus) 

 with a single cornutus. Female genitalia without signum; bursa 

 frequently smooth or weakly spined, occasionally with some 

 sclerotized folds continued from ductus bursae; the latter more 

 or less sclerotized in part, in many Pyla species broadly expanded 

 towards genital opening.] 



72. Telethusia, new genus 



Type of genus: Pempelia ovalis Packard. 



Tongue well developed. Antenna pubescent; on male 

 with sinus and enlarged scale tuft in base of shaft. 

 Labial palpus obliquely upturned, reaching to vertex 

 on male, above vertex on female; laterally flattened and 

 broadly scaled; second segment of male grooved on 

 inner side to hold the tongue; third segmelit consider- 

 ably shorter than second, bluntly pointed, more or less 

 deflected forward and partially hidden in scaling of 

 second segment. Maxillary palpus minute (a mere 

 vestige). Forewing smooth; 11 veins; vein 2 from 

 before lower outer angle of cell; 3 from the angle, 

 nearer to 4 than to 2 ; 4 and 5 separated at base, parallel 

 for a short distance beyond; 6 from below upper angle 

 of cell, straight; 8 and 9 stalked for half or nearly half 

 their lengths; 10 from the cell separated from the stalk 

 of 8-9 at base and divergent from it shortly beyond; 

 male without costal fold. Hind wing with vein 2 from 

 before lower outer angle of cell; 3 from the angle, 

 connate at base with the stalk of 4-5; 4 and 5 stalked 

 for about half their lengths; 7 and 8 contiguous or 

 weakly anastomosed for a short distance beyond cell; 

 cell less than half the length of wing; discoceUular vein 

 curved, outwardly produced at lower angle of cell. 

 Eighth abdominal segment of male with compound 

 scale tufts. 



Male genitalia with uncus subtriangulate; apex 

 bluntly rounded. Apical process of gnathos a short, 

 stout hook. TranstiUa absent. Harpe simple; clasper 

 rudimentary. Aedeagus simple, straight, not taper- 

 ing; penis unarmed except for a small comb of very 

 weak, short, slender spines. Vinculum stout, longer 

 than greatest width, tapering slightly to trimcated 

 terminal margin. 



Female genitalia with ovipositor strongly sclerotized; 

 apophyses (supporting rods) of ovipositor and eighth
