or entirely interrupted between veins. Cilia pale greenish olive, 

 partly infuscated, tips slightly mLxed with brown. 



Hind\nng modified, venation reduced, cell open, termen incised 

 on vein 5, dorsum curved downward and forming scent pouches. 

 Pale ochreous orange, edge with a broad continuous band of blackish 

 suffusion, upper edge of cell and veins 7 and 8 darker. Ciha pale 

 ochreous orange with white tips, a paler basal Une and a dark suffused 

 subbasal band. 



Male genitaha: Tegumen elongate, strong. Uncus bipartite, flat- 

 tened above and bent forward. Socius large, with sclerotized upper 

 edge. Gnathos darkly sclerotized, mth a median spHt, crowned 

 with two oval lobes. Valva rather slender, sacculus knob moderate, 

 cucullus elongate-oval, obhque, lower angle with short spines. 



A single specimen with rubbed dorsum. The genitaha show a 

 close relationship -w-ith Peridaedala crastidochroa Diakonoff, from 

 New Guinea. 



Female, 18 mm. Similar to the male, but deeper colored, with 

 markings darker, confluent in center of disc and suffused with brown 

 along median third of Aving. Palpus Avith median segment about 

 the half of that in P. dendrochlora. 



Unfortunately both specimens lack the abdomen and one hindwing 

 also; therefore it is not possible to describe the female genitaha.
