176 FAUNA HAWAIIENSIS 



(7) ScotorytJira aruraea, sp. nov. 



^?. 31 — 38 mm. Head and thorax in ^ brownish, in % light brownish-ochreous. 

 Antennae whitish-ochreous, fuscous-ringed, pectinations in ^ 8 — 9, laterally blackish- 

 lined. Abdomen in ^ \\, brownish, segmental margins ochreous-whitish, in % whitish- 

 ochreous sprinkled with dark fuscous. Legs in ^ fuscous, posterior tibiae mixed with 

 whitish-ochreous, somewhat dilated, enclosing a pale brownish-ochreous hair-pencil, in 

 % whitish sprinkled with dark fuscous, posterior tarsi in t i- Forewings rather 

 elongate-triangular, termen in I rather obliquely rounded, slightly waved, in % rather 

 obliquely bowed, hardly sinuate beneath apex, waved ; light ochreous-brown in ^, pale 

 brownish-ochreous to ochreous-brown in $, finely strigulated with dark fuscous ; first, 

 median, and second lines darker, indistinct (in % sometimes well-marked), first and 

 second more or less distinctly dotted with dark fuscous, first bent near costa, median 

 rather curved, second moderately curved on upper | ; a very indistinct darker trans- 

 verse discal spot, absorbed in median line ; in one strongly-marked $ a fuscous suffused 

 patch extending from middle of disc to termen, except towards costa and dorsum, and 

 a praesubterminal shade. Hindwings with termen waved ; colour and markings as in 

 forewings, but first line obsolete, discal spot imperceptible. (Plate IV. fig. 29.) 



13 specimens; 4 Kona, Hawaii, at 4000 feet; 8 Kilauea, Hawaii; i Olaa, 

 Hawaii ; from June to September, and in December. The females vary much in depth 

 of colouring, one being darker than any male, though most are lighter. Closely allied 

 to 6". isospora, from which it may be distinguished especially by the waved, not dentate, 

 termen of hindwings ; the average size is larger, the general colouring warmer and 

 deeper, and the forewings in the $ are without trace of the subapical sinuation, 

 which is faint yet perceptible in S. isospora ; the posterior tarsi in the $ are relatively 

 longer. 



(8) Scotorythi-a honiotrias, sp. nov. 



%. 42 mm. Head, thorax, and abdomen light brownish-ochreous, abdomen 

 sprinkled with dark fuscous. Antennae whitish-ochreous, ringed with dark fuscous. 

 Forewings triangular, termen hardly waved, slightly bowed, oblique ; brownish-ochreous, 

 faintly purplish-tinged, obscurely strigulated with dark fuscous, costa paler and sharply 

 strigulated ; first, median, and second lines indistinct, deeper ochreous, slightly curved, 

 nearly parallel and equidistant, first and second marked with series of blackish dots ; 

 a hardly darker praesubterminal shade. Hindwings with termen gently waved ; colour 

 and lines as in forewings, but colour rather deeper and yellower ochreous, first line 

 obsolete, others faint. 



I specimen, Olaa, Hawaii, in September. Differs from the preceding group by the 

 larger size, less curved termen and lines, and less waved termen of hindwings ; the 

 colouring is much as in 5. aruraea.
