248 U.S. NATIONAL MUSEUM BULLETIN 257 



Hindwing elongate semioval, pointed, under 1, cilia about 1. Vein 

 2 strongly curved at base, from 4/5, 3 from angle, 4 remote, straight, 

 5 approximated at base to 4, 6 remote, parallel to 7, accessory cell 

 distinct. 



Female genitalia: Eighth segment erected-conical, broadly split on 

 venter; edge mesially and caudally bristled. Ovipositor and postapo- 

 physes long, anapophyses moderate. Sterigma, a strongly sclerotized 

 funnel-shaped projecting structure, with a deeply excised upper edge 

 and an oblique rib on each side. Ductus bursae very broad, but 

 moderately long. Corpus bursae ovoid. Signum, two boat keel- 

 shaped sclerites. 



Type species: Protorhiza cyanosticta, new species (9) . 



Superficially suggesting a development of Ethmia stock, but differing 

 considerably by the presence of a distinct antennal pecten, and by the 

 position of veins 2 and 3 in both fore- and hindwing, so that a place 

 in the present family seems more natural. 



Protorhiza cyanosticta, new species 



Figures 355, 475, 743 



Female, 18 mm. Head whitish ochreous. Antenna dark fuscous, 

 mixed with some pale ochreous below. Palpus dark fuscous, tip of 

 median segment with a pale ochreous ring, terminal segment bluish 

 black, base pale ochreous. Thorax greyish fuscous, paler at edges, 

 anterior edge blackish fuscous, tips of tegulae whitish ochreous, dusky 

 pale ochreous fuscous. Abdomen fuscous. 



Forewing broadly lanceolate, pointed, costa strongly curved at 

 base, hardly curved towards apex, apex pointed, termen little curved, 

 long, very oblique. Whitish ochreous, obscurely spotted with grey 

 blue suffusion, scattered with dark fuscous scales, discal markings 

 fuscous brown. Anterior haK of wing along costa as far as vein 12, 

 apex, termen, and posterior half of dorsum UTegularly irrorated with 

 fuscous brown, some scales of the same color thinly strewn over the 

 wing. Stigmata fuscous brown, first discal moderate, elongate, before 

 middle; pUcal narrow and fasciate, below this; second discal large, 

 irregular, rounded, on closing vein, connected by a patch of denser 

 irroration with apex. Grey blue suffusion arranged thus: a faint 

 streak along extreme base of costal edge; three irregular rounded spots 

 along posterior fourth of costa, faintly extended anteriorly along veins 

 11-9 and upper edge of cell; posterior parts of veins lc-5 also faintly 

 streaked with grey bluish. Cilia pale ochreous mixed with fuscous 

 brown (imperfect). 



Hindwing rather light glossy golden fuscous, with a faint purplish 

 gloss in certain lights. Cilia light ochreous tawny.
