Chrysonoma fragmentaria, new species 



Figures 265-266, 653 



Male, 16 mm. Head, thorax ochreoiis whitish. Antenna with 

 scape ochreoiis whitish, flagellum brownish tinged: ciliations pale 

 brownish, 1. Palpus long, median segment exceeding base of antenna, 

 slightly spindle-shaped and laterally compressed, smooth; pale 

 ocherous, median segment gently infuscated, a subapical dark fuscous 

 irregular ring, tip whitish; terminal segment with some minute basal 

 dark markings, apical third except extreme tip, dark fuscous. Ab- 

 domen whitish, dorsum light tawny. 



Forewing ovate-lanceolate, rather narrow, costa gently curved, apex 

 rounded, termen rounded, oblique. Light ochreous, towards tornus 

 becoming whitish ochreous. Markings suffused, brownish fuscous. 

 A narrow line along basal half of costal edge; an elongate- triangular 

 fasciate patch on middle of costa, formed by sparse dusting; basal 

 patch indicated by some more dusting, irregular and tending to form 

 three longitudinal stripes, one of these probably being the first discal 

 stigma, at 1/4; second discal stigma elongate-oval, slightly before 2/3; 

 plical, horizontal, fasciate, halfway between discal stigmata; some 

 dusting in a transverse ill-defined band, tending to connect costal 

 patch with plical stigma and dorsum; an irregular wedge-shaped 

 streak from above second discal stigma to costa before apex, slightly 

 curved upwards; a sub terminal line, originating from outer edge of 

 preceding streak, running horizontally towards termen below apex, 

 then abruptly curving down, parallel to termen, slightly converging 

 with it, to tornus; this line tending to fall apart in a series of inter- 

 neural dots; a marginal line in apex and along upper third of termen. 

 Cilia ochreous whitish. 



Hindwing and cilia ochreous whitish, glossy. 



Male genitalia sclerotized. Tegumen rather short, conical. Uncus 

 as high as tegumen, triangular, top pointed and narrow. Gnathos 

 present, a pending hook. Vinculum strong, erected, as high as 

 tegumen. Caulis oval. Valva elongate oval, slightly rolled towards 

 top, costa and cucullus more sclerotized, the latter forming an apical 

 hook. Sacculus under 1, less sclerotized towards apex which is 

 obtusely pointed. Aedeagus moderately curved, narrowed, base 

 compressed and tortuous. Cornutus, a single, very long spine.
