AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



203 



of cell, connate with 3; 3 and 5 stalked for at least half 

 their lengths ; 7 and 8 anastomosed for at least half their 

 lengths beyond cell; cell less than one-half (nearer one- 

 third) the length of the wing; discoceUular vein curved. 

 Eighth abdominal segment of male simple. 



Male genitalia %\nth apical process of gnathos an ovate 

 plate terminating in a spinelike point. Uncus triangu- 

 late; apex bluntly pointed. Harpe narrowly elongate; 

 apex rounded; clasper absent. Anellus a triangulate, 

 flattened plate. Aedeagus moderately stout, sinuate 

 (slightly bent at one-third and again at two-thirds) ; 

 penis with a few W"eak scobinations, otherwise unarmed. 

 Vinculum stout, as broad as long, not tapering; terminal 

 margin evenly rounded. 



This genus is distinct from but apparently very close 

 to Cabotia, with which it agrees on a great many struc- 

 tural details of venation and male genitalia. It differs 

 in having the antennal shaft less strongly bent, the 

 labial palpus porrect rather than oblique, vein 9 of fore- 

 wing absent, eighth abdominal segment of male without 

 paired hair tufts, and harpe without clasper. It con- 

 tains but one known tropical American species.

 1914. 



Forewing luteous with a very faint rosy tint; costa 

 from base to apex rather broadly margined with white 

 very sparsely dusted with dark fuscous scales; an 

 oblique blackish band near base and extending from 

 inner margin to white costal stripe ; a rather conspicuous 

 patch of blackish scales near middle, between cell and 

 lower fold ; a similar smaller blackish spot at lower outer 

 angle of cell. Hind wing semihyaline, whitish, shaded 

 with pale fuscous along costa and at apex. Alar ex- 

 panse, 11-13 mm. 



Type locality: La Chorrera, Panamd (May, type 

 in USNM). 



Food plant: Unknown. 



Represented in the National Collection by the type, 

 eight other males from the type locality, and one male 

 from Rio Trinidad, Panamd (June). The female is 

 unknown. 



Genera 107-109: Eurythmasis to Wunderia 



(Venational division B. Forewing with 10 veins; 9 present; 2 

 and 3 stalked or united, from lower outer angle of cell. Hind 

 •wing with 2 from lower outer angle of cell; 3 and 5 stalked for at 

 least half their lengths; 7 and 8 strongly anastomosed. Uncus 

 triangulate. Transtilla incomplete.] 



107. Genua Eurythmasis Dyar 



Eurythmasis Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 338, 1914. 

 (Type of genus: Eurythmasis ignifatua Dyar.) 



Tongue well developed. Antenna pubescent; basal 

 segment elongate; on male shaft with a hook from its 



basal segment and curved for a few segments beyond; 

 on female simple. Labial palpus obhque, long, extend- 

 ing more than half its length above vertex; smooth; 

 segment 2 on male grooved to hold the maxillary palpus; 

 segment 3 very short, acuminate. Maxillary palpus 

 of male in the form of an aigrette; of female filiform. 

 Forewing smooth; 10 veins; veins 2 and 3 long stalked, 

 from lower outer angle of cell; 4 absent; 5 separated 

 from 2-3 at base; 6 from below upper angle of cell, 

 straight; 8 and 9 stalked; 10 from cell, not approximate 

 to 8-9; male without costal fold. Hind wing with vein 

 2 from lower outer angle of cell, connate with the stalk 

 of 3-5; 3 and 5 stalked for half their lengths; 7 and 8 

 anastomosed for half their lengths; cell one-third the 

 wing length; discoceUular vein curved. Eighth ab- 

 dominal segment of male with compound ventral tufts. 



Male genitalia with apical process of gnathos an 

 elongate, rather narrow hook. Uncus triangulate ; apex 

 pointed. Harpe elongate, slender; apex rounded; 

 clasper vertical, pointed, slightly curved. Anellus a 

 small, weakly sclerotized, cupped plate. Aedeagus 

 moderately stout, nearly straight; penis with a few 

 minute spines and granulations, otherwise unarmed. 

 Vinculum stout, a trifle longer than broad, not appre- 

 ciably tapering to broad terminal margin. 



Female genitalia with signa strongly developed, con- 

 sisting of a large, curved, oval (or round), densely spined 

 plate and a few detached spines near or opposite the 

 plate; ductus bursae approximately the same length as 

 bursa, minutely scobinate for a short distance from 

 junction with bursa; genital opening simple; ductus 

 seminalis from bursa near its junction with ductus bursae. 



In habitus and all structural characters except vena- 

 tion this genus resembles Oncolabis, to which it is ap- 

 parently closely related. It contains one tropical 

 American species.

 p. 338, 1914. 



Forewing gray brown; a white border along costa 

 sparsely dusted with reddish scales ; on middle of inner 

 margin a narrowly elongate, dull ocherous patch with a 

 knoblike projection at each end extendrug to the cell; 

 a few reddish scales on dark ground color at base of 

 wing and bordering inner margin; transverse lines ob- 

 solete. Hind wing semihyaline; in female with some 

 fuscous shading on the veins. Alar expanse, 13-14 mm. 



Genitalia as given for the genus; male with terminal 

 margin of vinculum slightly angled.
