MACROLEPIDOPTERA 185 



4 specimens; 2 Waimea Mts., Kauai, at 4000 feet; 2 Kaholuamano, Kauai, at 

 4000 feet; from April to June. A peculiar species, distinguishable by the waved- 

 dentate lines and unusually elongate forewings, with other characteristics ; the t differs 

 from all by the glandular discal patch of scales beneath, which would admit of generic 

 separation but does not seem to require it. 



(23) Scotorythra macrosoma, sp. nov. 



<??• 36—55 mm. (larger specimens usually ?). Head and thorax brown or 

 fuscous, sometimes mi.xed with whitish or dark fuscous, sometimes mostly suffused with 

 whitish and then showing dark fuscous anterior band and two posterior transverse lines 

 on thorax. Antennae whitish, irregularly spotted or blotched with dark fuscous, 

 pectinations 6, irregularly blotched. Abdomen pale fuscous, somewhat darker-mixed, 

 in t almost 2. Legs whitish or ochreous-whitish, spotted and blotched with dark 

 fuscous, posterior tibiae in ^ dilated, enclosing a whitish-ochreous hair-pencil, posterior 

 tarsi in ^ I . Forewings elongate-triangular, termen waved, bowed, oblique ; varying 

 from fuscous to light ochreous-brown or fuscous-whitish, rather thinly strewn with dark 

 fuscous strigulae or dots ; first and second lines darker, conspicuously dotted with dark 

 fuscous on veins, first strongly curved, bent above middle and somewhat sinuate near 

 dorsum, nearly preceded by a parallel dark shade which in pale specimens is very 

 conspicuous, second waved, sinuate inwards above middle and towards dorsum, some- 

 times followed by an indistinct pale line and then by a dark shade ; discal spot large, 

 broadly dilated on lower half, wholly suffused with dark fuscous, sometimes preceded 

 and followed by patches of white suffusion extending to first and second lines ; sub- 

 terminal line obscurely pale or seldom whitish, sometimes edged anteriorly with darker 

 suffusion ; sometimes an apical spot of pale suffusion, edged beneath with darker ; 

 a terminal series of dark fuscous dots. Hindwings with termen waved ; fuscous or 

 grey, lighter towards base, obscurely darker-strigulated ; a dark grey transverse discal 

 spot, and bisinuate postmedian series of dots. (Plate V. fig. 2.) 



78 specimens; 63 Olaa, Hawaii; 3 Hilo, Hawaii; 2 Molokai ; 6 Kaholuamano, 

 Kauai, at 4000 feet; 4 Waimea Mts., Kauai, at 4000 feet; in January, April to June, 

 September, November, and December. The $ differs from all by the peculiarly 

 long abdomen ; the species varies considerably in colour, but the characteristic 

 large dark discal spot, dilated beneath, is always prominent, and renders it easy of 



recognition. 



(24) Scotorythra pachyspila, sp. nov. 



^?. 36 — 45 mm. Head and thorax fuscous, mixed with whitish and dark fuscous 

 and sometimes with red-brown, crown and thorax sometimes wholly dark fuscous.
