as in forewings. but first line obsolete, second hardly curved inwards near dorsum, 

 discal spot much smaller and less distinct. (Plate IV. fig. 28.) 



I specimen, Waimea Mts., Kauai, at 4000 feet, in May. Rather markedly distinct 

 by its size, grey-striated appearance, more rounded dorsum of forewings, length of 

 discal spot, and form of second line.

<?¥• 27 — 35 mm. Head, thorax, and abdomen varying from light fuscous or grey 

 to (in ?) whitish-ochreous, abdomen in ^ i^— ij, segmental margins white. Antennae 

 whitish-grey or ochreous-whitish, darker-ringed, pectinations in $ 7 — 8, whitish, laterally 

 black-lined. Legs grey, posterior tibiae whitish-mixed, in ^ somewhat dilated, enclosing 

 a whitish hair-pencil, posterior tarsi in <? f to almost i. Forewings somewhat elongate- 

 triangular, termen in ^ faintly, in ? more distinctly sinuate beneath apex, bowed, rather 

 oblique ; in ^ fuscous or grey, varying in depth, more or less densely strigulated with 

 dark fuscous, in % brownish-ochreous to ochreous-whitish, densely strigulated with 

 fuscous ; first and second lines indistinctly darker, obscurely dotted with blackish, second 

 sometimes posteriorly pale-edged, in one % first obsolete and second represented by a 

 white streak, first slightly curved, second with upper f moderately curved or bent out- 

 wards ; a transverse-oval discal spot indistinctly dark-outlined, sometimes traversed by 

 a dark fuscous median shade ; seldom a darker praesubterminal shade and subapical 

 suffusion. Hindwings with termen waved; colour, discal spot, median shade, second 

 line, and praesubterminal shade as in forewings. 



12 specimens; 10 Kona, Hawaii, at 2000 — ^4000 feet; i Kilauea, Hawaii; i 

 Lanai, at 3000 feet ; from July to September. Butler's type was from Lanai, and I 

 have also two other specimens of Mr Blackburn's from the same locality. A very 

 variable species, but easy of recognition ; its comparatively small size, greyish colouring, 

 outlined discal spot, and form of second line are its most prominent characters.
