467. Rotruda inucidella affusella (Ragonot), new combination 



Homoeosoma affusella Ragonot, Nouv. Gen., p. 34, 1888; Mono- 

 graph, pt. 2, p. 260, 1901. 



The name ajffxLsella is doubtfully placed here in associ- 

 ation with mucidella, for Ragonot's description and 

 figure suggest something quite different, possibly similar 

 to what I have described as Homoeosoma vepallidum. 

 However, Clarke's notes on the type discoimt the figure 

 (Monograph, pi. 33, fig. 24) and, to a considerable 

 degree, the original description. He states that "the 

 figure is poor. The dorsal spot at basal third is dis- 

 tinct but the excurved line costad is very faint. The 

 8. t. line of dashes, which is so prominent in the figure, 

 is scarcely discernible in the specimen. On the fore- 

 wing there is a heavier dusting of white than is indi- 

 cated in the drawing." This suggests a rather pale, 

 not too well marked example of mucidella. We shall 

 have to await recovery of examples matching the tjrpe 

 from Argentina before the status of the name affusella 

 can be definitely settled. The abdomen of the type 

 was no help. It has been glued on and is obviously 

 spurious. I examined the genitaha (9). They are 

 those of Ephestia elutella. 



Alar expanse, 18 mm. 



Type locality: Cdrdoba, Argentina (type in Paris 

 Mus.). 



Food plant: Unknown. 



Genus 129: Strephomescinia 



[Venational division B. Forewing with 9 veins: 10 from cell; 

 8 and 9 united; 4 and 5 united; 2 and 3 stalked. Male genitalia 

 with transtilla incomplete.] 



129. Genus Strephomescinia Dyar 



Strephomescinia Dyar, Ins. Insc. Menstr., vol. 7, pi 60, 1919. 

 (Type of genus: Strephomescinia schausella Dyar.) 



Tongue well developed. Antenna pubescent; shaft 

 simple. Labial palpus upturned. Maxillary palpus 

 filiform. Forewing smooth; 9 veins; veins 2 and 3 long 

 stalked from angle of cell; 4 and 5 united; 6 straight; 8 

 and 9 united; 10 from the cell but closely approximate 

 to 8-9 for some distance; male with weak costal fold. 

 Hind wing with vein 2 from well before angle of cell, 

 straight and parallel with 3; 3 and 5 from angle and 



closely approximate at base; 6 from upper angle of cell; 

 7 and 8 completely fused beyond cell; discocellular vein 

 curved; cell about one-fourth the wing length. Abdo- 

 men of male with a pair of ventrolateral hair tufts. 



Male genitaha with imcus triangulate. Gnathos 

 terminating in a small bifid apical process. Harpe 

 simple; costa broadly sclerotized for most of its length. 

 Aedeagus straight, simple, moderately slender. Penis 

 very weakly scobinate, otherwise unarmed. Vinculum 

 stout, short, terminal margin truncate. 



This genus is known only from the male of the tjrpe 

 species but is easily identified by its venation. The 

 genitalia show the close affinity of Strephomescinia to 

 both Homoeosoma and Mescinia. 



468. Strephomescinia Schaueella Dyar 

 Figures 93, 497 



Strephomescinia schausella Dyar, Ins. Insc. Menstr., vol. 7, p. 60, 

 1919. 



Forewing whitish gray, irregularly and faintly 

 marked with fuscous; a dark streak along submedian 

 fold and some dark strealdng on the veins toward 

 termen; discal spots elongate, separate; no transverse 

 lines distinguishable. Hind wing translucent, with the 

 veins outlined by dark scaling; terminal and costal 

 margins narrowly dark-margined. The one available 

 specimen is badly rubbed. Fresh specimens would 

 probably exhibit a more definable pattern. Alar ex- 

 panse, 9.5 mm. 



Male genitalia with apex of uncus bluntly pointed; 

 cuccidus of harpe oval, apex evenly rounded; elements 

 of divided transtilla long and slender. 



Type locality: Santiago, Cuba (June; type in 

 USNM). 



Food plant: Unknown. 



So far represented only by the unique male type. 



Genus 130: Unadilla 



[Venational division E. Forewing with 9 veins: 10 from cell; 

 9 absent (8 and 9 united): 4 absent (4 and 5 united); 2 and 3 

 from cell. Hind wing with discocellular vein straight and verti- 

 cal. Male genitalia with transtilla incomplete; uncus broad 

 throughout. Female genitalia with genital opening simple 

 (unsclerotized and without adjacent armature).]
