AMERICAN MOTHS OF THE SUBFAMILY PHYCITINAE 



311 



plate. Transtilla complete and greatly developed. Un- 

 cus absent. Harpe with cucullus projecting into a blunt 

 point at apex. Anellus semitubular with elongate, 

 slender, lateral lobes. Aedeagus curved, slightly ta- 

 pered. Penis without armature. Vinculum as broad 

 as long. 



Female genitalia with ductus bursae membranous, 

 slender, longer than bursa; bm'sa copulatrix roimd, mem- 

 branous; signum a finely, densely spined plate; genital 

 opening simple; ductus seminalis from middle of bursa. 



A tropical genus of uncertain affinities. Dyar's inter- 

 pretation of the forewing venation differs from mine. 

 He considered vein 4 absent and veins 3 and 5 stalked. 

 The end result would be the same, whichever interpreta- 

 tion is accepted. 



639. Microphycita titillella Dyar 

 Figures 130, 636, 1137 

 Microphycita titillella Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 346, 

 1914. 



Forewing dull ocherous with a narrow dark (fuscous) 

 shade along costa and termen, expanding somewhat at 

 tornal area; transverse lines obscure; the antemedial line 

 near middle of wing, vertical and straight, indicated 

 chiefly by a narrow, fuscous, outer border; sub terminal 

 line well back from terminal margin, also indicated by a 

 narrow, inner border, subparallel to antemedial line; no 

 distinguishable discal dots. Hind wing pale smoky fus- 

 cous. Alar expanse, 6-8 mm. 



Genital characters as given for the genus. 



Type locality: Elo Trinidad, Panami (type in 

 USNM). 



Food plant: Unknown. 



Distribution : PanamA : Cabima (May) , Rio Trinidad 

 (Mar., May, June). 



194. Rabiria, new genus 



Type of genus: Microphycita conops Dyar 

 Characters of Microphycita except: Forewing with 



vein 10 from the cell, separated from 8 at base. Hind 

 wing with veins of normal length; vein 2 from before 

 lower outer angle of cell; cell closed, discoceUular vein 

 curved. Male genitalia with apical process of gnathos 

 well developed, U-shaped; uncus strongly developed 

 (similar to that of Cabnia) ; harpe simple, elongate, api- 

 cal margin evenly rounded ; anellus a simple curved band , 

 without lateral lobes; aedeagus straight, not tapering; 

 transtilla a narrow, arched bridge. Female genitalia 

 with signum a small, smooth disk. 



This genus is erected to receive conops originally in- 

 cluded in Microphycita by Dyar along with the type 

 species (titillella) of the latter genus. Why Dyar ever 

 included the two species under one generic heading — 

 even without examination of their genitalia — is difficult 

 to understand; for the hind wing venation of the two 

 is radically different. 



640. Rabiria conops (Dyar), new combination 



Figures 129, 635, 1136 



Microphycita conops Dyar, Proc. U. S. Nat. Mus., vol. 47, p. 346, 

 1914. 



Forewing dark fuscous with a faint bronzy sheen; 

 without transverse lines or discal spots. Hind wing 

 pale translucent fuscous. Alar expanse, 8 mm. 



Genitalic characters as given for the genus. 



Type locality: La Chorrera, Panamd (type in 

 USNM). 



Food plant: Unloiown. 



Distribution: PanamA : Cabima (May), La Chorrera 

 (Apr., May) Rio Trinidad (May). 



Represented so far only by the original type series, 

 three males and one female. The type is a male (not a 

 female as stated by Dyar). The genitalia are figured 

 from this specimen and from a female (Ivlay) from the 

 type locality.
