AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAB 



211 



Genera 118-120: Aptunga to Cassiana 



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

 8 and 9 stalked, 6 straight, 4 and 5 stalked, 2 and 3 separate or 

 approximate. Hind wing vdth 7 veins; 7 and 8 strongly anasto- 

 mosed, 3 and 5 approximate at base or stalked, discoceUular vein 

 curved. Male genitalia with uncus subtriangular, tapering 

 abruptly, apical half narrow, bluntly pointed; gnathos ter- 

 minating in a small, bifid, hooked process; transtilla incomplete, 

 represented by a pair of separate, elongate plates; harpe simple, 

 elongate, apex obliquely rounded; vinculum stout, decidedly 

 longer than broad; aedeagus moderately stout, straight; penis 

 without cornutus. Female genitalia with ductus seminalis from 

 bursa.] 



118. Aptunga, new genus 



Type of genus: Vitida macropasa Dyar. 



Tongue well developed. Antenna pubescent, shaft 

 simple in both sexes. Labial palpus obliquely up- 

 turned. Maxillary palpus filiform. Forewing nar- 

 rowly elongate, smooth; veins 2 and 3 closely approxi- 

 mate from lower outer angle of cell; stem of 4-5 approxi- 

 mate to 3; vein 10 from the cell, rather well separated 

 from stalk of 8-9; male without costal frold or other 

 sexual modifications. Hind wing with vein 2 from well 

 before angle of cell; 3 and 5 closely approximate at 

 lower, outer angle of cell; 7-8 anastomosed for most of 

 their lengths beyond cell (free end of vein 8 very short 

 and weak); cell less than half the length of wing. 

 Abdomen of male with a strong pair of ventrolateral 

 hair tufts from eighth segment. 



Male genitalia with apical process of gnathos small, 

 bifid; aedeagus simple (without longitudinal ventral 

 sclerotized ridge). 



Female genitalia without signum; bursa copulatrix 

 more or less finely scobinate in the area about attach- 

 ment of ductus seminalis, otherwise smooth; ductus 

 bursae smooth except for a weak sclerotization near 

 genital opening and some fine scobinations at junction 

 with bursa; ductus seminalis from middle or near 

 middle of bursa. 



This genus and the two genera following are closely 

 related to each other and Mescinia, agreeing in nearly 

 all male genitalic characters but differing in venation. 

 Aptunga is similar in hind wing venation to Mescinia, 

 differing from the latter in having veins 2 and 3 of 

 forewing closely approximate at base rather than 

 stalked, and lacking the signum in butrsa of the female. 



417. Aptunga macropasa (Dyar), new combination 



Figures 85, 465, 958 



Vitula macropasa Dyar, Ins. Insc. Menstr., vol. 7, p. 61, 1919. 



Forewing grayish fuscous; antemedial Ime obscure, 

 whitish, bordered outwardly by a diffused dark shade; 

 subterminal line narrow, whitish, decidedly slanting 

 and slightly angled near middle, shaded inwardly and 

 outwardly by dark streaks on the veins; a row of small 

 blacldsh dots along termen; discal dots at end of cell 

 separate, somewhat elongate ; under magnification costa 

 shows a peppering of reddish scales. Hind wing 

 whitish, semihyaline, the veins outlined with fuscous 



and a fuscous shade bordering costa and along terminal 

 margin. Alar expanse, 19-23 mm. 



Male genitaUa with weak sclerotized granulations 

 and wrinklings on penis. Female genitaha with a 

 narrow band of sclerotized granulations on inner 

 dorsal surface of ductus bursae at genital opening. 



Type locality: Purulhd, Guatemala (type in 

 USNM). 



Food plant: Unknown. 



Distribution: Guatemala: Chejel (Aug.), Purulhd 

 (July), Volcan Santa Maria (Nov.). Mexico: Orizaba. 



418. Aptunga imperfecta (Dyar), new combination 



FiGUBE 957 

 Mescinia inperfecla Dyar, Ins. Insc. Menstr., vol. 7, p. 60, 1919. 



Considerably shorter and somewhat paler than 

 macropasa, the general color (in the rubbed type) more 

 brownish than grayish fuscous; no trace of reddish 

 scaling in costal area of forewing; discal dots fused into 

 a single round dark spot. Hind wing darker, less 

 hyaline than that of macropasa. Alar expanse, 14 mm. 



Female genitaha with the ductus bursae appreciably 

 but not strongly sclerotized and granulate for a short 

 distance from genital opening. 



Type locality: Cayuga, Guatemala (Apr., type in 

 USNM). 



Food plant: Unknown. 



Known only from the female type; described by 

 Dyar in Mescinia but ruled out of that genus by its 

 forewing venation and lack of signum. 



119. Anderida, new genus 



Type of genus: Euzophera sonorella Ragonot. 



Tongue well developed. Antenna pubescent, shaft 

 simple in both sexes. Labial palpus obliquely up- 

 turned. Maxillary palpus filiform. Forewing narrowly 

 elongate, smooth; vein 2 from near angle of cell but 

 well separated from 3; 10 from cell, separate from 

 stalk of 8-9; male without costal fold or other sexual 

 modifications. Hind wing with 3 and 5 stalked; 7-8 

 anastomosed for at least two-thirds the length of vein 

 7 ; cell approximately half the length of wing. Abdomen 

 of male with strong pair of ventrolateral hair tufts 

 from eighth segment. 



Male genitalia as in Aptunga except apical process of 

 gnathos partially fused. 



Female genitaUa with signum; ductus seminalis from 

 anterior end of bursa; ductus bursae with a thin 

 sclerotized shield on venter at genital opening and more 

 or less finely scobinate towards bursa, otherwise smooth.
