pectinations in ^ 8, irregularly blotched with blackish. Abdomen light fuscous with 

 lateral blackish marks, in ^ i^, with small expansible ventral hairpencil before middle. 

 Legs vvhitish-ochreous spotted with dark fuscous, posterior tibiae in Z dilated, enclosing 

 an ochreous-whitish hairpencil, posterior tarsi in J |-. Forewings elongate-triangular, 

 termen strongly waved, bowed, rather oblique ; brown, ochreous-brown, or golden- 

 ochreous, more or less mixed with whitish, and strio-ulated with black ; first and second 



o 



lines double, strong, black, intersected by pale veins, first obtusely angulated in middle, 

 second sinuate inwards above middle and more strongly towards dorsum, more or less 

 interrupted, especially on posterior gemination ; discal spot large, transverse-oval, 

 blackish, enclosing ochreous-whitish transverse vein, placed on median shade, which is 

 generally indicated only by two or three cloudy blackish spots ; costal half between first 

 and median lines, and a band beyond second line usually paler and mixed with whitish 

 suffusion; subterminal line obscure, whitish or ochreous-whitish, waved-dentate. Hind- 

 wings with termen rather strongly waved, rounded ; grey ; a small darker discal spot ; 

 a postmedian series of darker dots. 



Eleven specimens, N.W. Koolau range, Oahu, in July. Allied to .S'. trapezias, which 

 it may follow, but easily distinguished by obtuse (not acute) angulation of first line, 

 well-marked black discal spot, and other points. 



Scotorythra uictacrossa, sp. nov. 



Z 23 — 27 mm., $ 30 mm. Head and thorax ochreous-brown mixed with darker. 

 Antennae whitish-ochreous spotted with dark fuscous, pectinations in ^ 6, irregularly 

 blotched with dark fuscous. Abdomen whitish-ochreous, towards base sprinkled with 

 dark fuscous, in ^ i^. Legs pale brownish-ochreous spotted with dark fuscous, posterior 

 tibiae in $ dilated, enclosing an ochreous-whitish hairpencil, posterior tarsi in ^ ^. 

 Forewings elongate-triangular, termen faintly waved, bowed, oblique ; ferruginous-brown, 

 partially sprinkled with whitish-ochreous, and irregularly strewn with short blackish 

 strigulae ; first and second lines well-defined, dark fuscous, first acutely angulated above 

 middle, second waved, partially interrupted, indistinctly sinuate inwards above middle 

 and towards dorsum ; discal spot rather large, crescentic-oval, irregularly outlined with 

 dark fuscous or blackish, centre sometimes mixed with whitish-ochreous ; median shade

 rounded, hardly waved ; pale grey ; a postmedian series of darker dots. 



Twelve specimens (including only one ?), N.W. and S.E. Koolau range, Oahu, in 

 July. Probably allied to S. idolias and paindicola, but differs in smaller size, deeper 

 colour, blotched antennal pectinations, and other details.
