tinge in certain lights. Spots dull black, very faintly encircled with 

 paler. A suffused spot beyond base of costa, connected with a narrow 

 short marginal strigula; a round spot on fold well beyond base; 

 two larger oval spots representing discal stigmata, first median; 

 plical stigma elongate, obliquely before first discal; three smaller, 

 somewhat elongate spots between cell and margin, upper close below 

 costa before angle, second before angle, more distant from edge, 

 third halfway between second discal and lower part of termen; some 

 8 or 9 small marginal subquadrate or fasciate spots along costa before 

 apex, in apex and along termen to tornus. Cilia grey. 



Hindwing light fuscous grey, becoming somewhat darker towards 

 apex. Cilia whitish. 



Female genitalia: Genital segment sclerotized, forming a distinct 

 dark ring. Sterigma shaped as a pending subcordiform plate, with 

 upper edge twice emarginate, sclerotized. Colliculum for a part 

 heavily sclerotized, elongate, tortuous, asymmetrical. Posterior edge 

 of seventh sternite also darkly sclerotized. Walls of corpus bursae 

 granulate, without signum. 



Material examined: Mindanao, Zamboanga, "Ace. 5122," 1 9, 

 holotype, genit. slide 5715 (AMNH). 



Closely allied to E. octanoma Meyrick from Formosa (the type 

 of which seems to be lost) but differing by the coloring of head and 

 palpi and by the arrangement of dark spots in the foremng. 



Ethmia nobilis, new species 



Figures 397, 409, 754 



Female, 22-25 mm. Head, palpus and thorax greyish white, 

 palpus with terminal segment black in front, thorax with a pair 

 of black spots anteriorly, a spot on top of each tegula, a curved sub- 

 apical black transverse band. Abdomen light yellow becoming 

 whitish toward base, venter pale yellow. 



Forewing oblong, moderately dilated, costa ciu"ved, apex subobtuse, 

 termen gently sinuate and slightly convex. Glossy, light slate grey 

 with a faint purplish hue. Markings black, faintly edged whitish, 

 reduced in number. Three elongate plical dots, becoming larger 

 posteriorly, first minute, beyond base, third before middle of fold, 

 second midway the preceding, but slightly shifted towards the basal 

 dot; a larger oval spot in cell in middle of wing, i.e., above and beyond 

 third plical spot; three subapical dots, moderate, rounded, in a 

 triangle, two almost in line with the discal dot, third subcostal, very 

 near to first costal dot; a row of eleven marginal dots, three along 

 costa, foiu*th apical, some terminal dots more or less interconnected, 

 last dot minute, longitudinal, on end of dorsum. Cilia pale grey.
