(19) Scotorythra capnopa, sp. nov. 



<??■ 36— 39 mm. Head and thorax dark fuscous. Antennae whitish, blotched 

 or in ? almost wholly suffused with dark fuscous, pectinations 6, irregularly blotched. 

 Abdomen grey, in $ ii. Legs dark fuscous, spotted with ochreous- whitish, posterior

 Forewings elongate-triangular, termen waved, bowed, rather oblique ; fuscous, strigu- 

 lated or almost wholly suffused with dark fuscous, veins pardy ochreous-tino-ed ; first 

 and second lines blackish-fuscous, edged externally with dark fuscous shades, irregular, 

 first gently curved, second sinuate inwards above middle and more widely towards 

 dorsum ; discal spot large, transverse-oval, usually only obscurely darker-outlined, in 

 one ? mixed with ochreous ; between second and subterminal lines a somewhat lighter 

 fascia, in one $ brownish-ochreous ; subterminal line only indicated by an undefined 

 dark brown shade ; sometimes a terminal series of pale ochreous dots. Hindwings 

 with termen waved ; grey, darker posteriorly, indistinctly darker-strigulated ; a faint 

 darker discal spot. 



9 specimens, Olaa, Hawaii, in June and September. Characterised by the rather 

 small size and dark colouring, with darker shades attached to first and second lines. 



(20) Scotorythra platycapna, sp. nov. 



%. 47 mm. Head, thorax, and abdomen rather dark fuscous, pale-sprinkled. 

 Antennae light greyish-ochreous, fuscous-sprinkled. Legs pale greyish-ochreous spotted 

 with dark fuscous. Forewings triangular, termen waved, rather strongly bowed, 

 oblique ; rather dark fuscous, darker-irrorated ; veins posteriorly and costal edge 

 obscurely ochreous ; a curved band of obscure ochreous suffusion towards base, and 

 a nearly straight one at about f , enclosing unusually broad median band ; lines 

 obsolete ; a linear curved transverse grey discal spot, edged anteriorly with dark 

 fuscous suffusion, and posteriorly with two small dark fuscous spots. Hindwings with 

 termen unevenly waved ; fuscous, obscurely darker-strigulated. 



I specimen, Waimea Mts., Kauai, at 4000 feet, in May. A peculiar form of 

 dubious specific relationship ; the unusually broad forewings (especially for a female), 

 the obsolescence of all lines, and character of the discal spot are the most noticeable 

 points, but the male may differ considerably in appearance.

 Antennae ochreous-whitish, irregularly spotted and in % mostly suffused with dark
