^^. 28 — 33 mm. Head and thorax varying from fuscous-whitish or whitish- 

 ochreous to reddish-ochreous or dark fuscous. Forewings with termen obtusely 

 projecting on vein 4 ; varying from pale ochreous to rather dark fuscous, usually more 

 or less reddish-tinged, sometimes partially whitish-suffused, often darker-strigulated ; 

 subbasal line forming a triangular black mark (rarely unicolorous), pale-edged, its 

 anterior edge being straight and posterior edge acutely angulated ; first and second 

 lines slender, pale or whitish, included median band sometimes wholly suffused with 

 dark fuscous, usually more or less black-marked on edges, anterior edge strongly 

 concave, with a strong acute projection above dorsum, posterior edge indented 

 immediately beneath costa, below this with a short rectangular projection, and a similar 

 one in middle, lower half curved inwards ; orbicular represented by a minute white dot ; 

 lower edge of reniform usually indicated by a whitish dot, sometimes upper edge also 

 marked by a similar dot ; a more or less distinct praesubterminal series of cloudy darker

23 specimens ; 14 Kaholuamano, Kauai ; 5 Mts. Waimea, Kauai, at 4000 feet ; 

 I Wailuku, Maui; 3 Waianae Mts., Oahu, at 2000 feet; from April to June. Also 

 one specimen in British Museum, taken by Mr Blackburn on Haleakala, Maui, at 

 4000 feet. Varies considerably in colour and intensity.

Varies from light brownish or reddish-ochreous to dark brown ; in one specimen 

 the median band is wholly deep red-brown mixed with black. Besides the different 

 character of the subbasal line, the species differs from C. nodivolans in the different 

 form of the first and second lines, and the larger size. 



15 specimens; 4 Olaa, Hawaii, at 2000 feet, in November; 4 Kaholuamano,
