MACROLEPIDOPTERA i8i 



with dark fuscous, in % ochreous-white ; a terminal series of dark fuscous dots. Hind- 

 wings with termen sHghtly waved ; pale fuscous ; a faint postmedian series of darker 

 dots. 



2 specimens received by me from Mr Blackburn : locality not indicated, but 

 not improbably Haleakala, Maui. The white veins and markings of the female 

 specimen are very possibly not constant. The species is best recognised (except 

 from S. ortharclia) by the prominent apex of the forewings ; the proportionately 

 long abdomen of the male, the unspotted shaft of antennae, and the strongly angulated 

 first line are also notable characters. 



(i6) Scotorythra ortharcha, sp. nov. 



Z%. 32 — 39 mm. Head and thorax dark grey or ashy-fuscous, sometimes 

 irrorated with black. Antennae fuscous spotted with black, pectinations 7, whitish, 

 laterally black-lined. Abdomen pale grey, sometimes sprinkled with black, in ^ i^. 

 Legs dark grey, tips of joints whitish, posterior tibiae in t httle dilated, enclosing 

 a whitish hair-pencil, posterior tarsi in Z f ■ Forewings rather elongate-triangular, apex 

 distinctly prominent, termen sinuate beneath apex, bowed, v/aved, oblique ; purple- 

 whitish to light fuscous, sometimes partially bluish-tinged, densely strigulated with 

 dark fuscous or blackish ; first line pale, more or less obscure, placed in a dark fuscous 

 fascia of which the anterior edge is quite straight and sharply defined, posterior less 

 sharp ; a cloudy rather dark fuscous straight median shade, preceding discal spot, 

 which is curved-linear, pale or white, black-edged ; second line slender, whitish, 

 interrupted, sinuate inwards above middle and more widely towards dorsum, suffusedly 

 edged with dark fuscous ; subterminal line pale or nearly obsolete, especially towards 

 dorsum, posteriorly edged by a darker shade ; a terminal series of blackish dots. 

 Hindwings with termen waved; grey; a fine irregular waved darker postmedian line, 

 followed by a faint less dark shade. (Plate V. fig. i.) 



9 specimens, Olaa, Hawaii, at 2000 feet, from September to November. This 

 and the following species are distinguished from all others by the entire waved line 

 of the grey hindwings, and also by their usually bluish-tinged forewings ; they are 

 separated from each other by the difference in the first line, which in 6*. ortharcha 

 is practically straight, in 5. oxypliractis acutely angulated near costa. 



(17) Scotorythra oxyphractis, sp. nov. 



^ 35 — 45 mm., % 37 — 51 mm. Head and thorax dark brown sprinkled with white. 

 Antennae in $ yellow-ochreous, pectinations 8 — 9, whitish above, elsewhere dark
