8. Nyctipao hieroyhjphica ienehrata, subsp. n. 



^ . — Diflfevs frcm N. h'uroyhjpliica in the complete 

 absence of the pale poslnicdiau niaikiiigs on botli surfaces 

 of tl e fore wing. 



$ . — Pale markings much reduced, especially on the 

 underside ; sul)apical streak of fore wing very narrow. 



N. Borneo, type ($ and allotype $ (Sandakan). 



Misidentified by Hampson as purpurata, Druce, but 

 differing in the venation of the fore wing (see Hanipson's 

 excellent classification in Cat. Lep. Phal. xii. p. ^73 seq.) and 

 slightly in the hind wing. 



9. Nyclipao alhicrustata, sp. n. 



$ .—ICO mm. 



Head and body brown, the upperside of thorax strongly, 

 of abdomen less strongly, daikened. Fore and middle legs 

 predominantly deep brown. 



Fore icing with the colours and pattern arranged as in ^ 

 leucotania, Guen. (Hmpsn., Cat. Lep. Phal. xii. t. ccvii. f. 7), 

 but less tinged with ochreous or reddish ; proximal area 

 more uniformly dark, the antemedian line (often distinct 

 in leucotania) consequently almost entirely obsolete ; white 

 band outside median line broad from SC to beyond R' 

 (5 mm. in cellule 7) ; subterminal wlilte spots anteriorly 

 placed further from termen, the series consequently forming 

 a less acutely angulated line; the subcostal one considerably 

 more elongate (anteriorly 8 mm.), the second also elongate 

 (circ. 4 mm.), the rest moderate, wedge-shaped or triangular, 

 posteriorly ill-defined. 



Hi/td icing with white subapical spot longitudinal, not 

 oblique ; subterminal otheiwise obsolescent, almost parallel 

 with postmedian throughout. 



Fore wing beneath with the white submarginal spots 

 greatly enlarged, as compared with those of Itucotania, the 

 first (as above) 8 mm., the second and third larger than 

 above, connected with an ill-defined })ale shade proximally, 

 those in cellules 5, 4, and 3 very large (9-10 mm.), the 

 former two proximally reaching the uicdian line. Hind 

 wing beneath with the first white subterminal spot as above, 

 the second moderate, the rest present but indistinct, forming 

 a nearly strai;4ht line, in sharp contradistinction to the 

 highlv-angled one of leucotatnia. 



Key Islands, Jan.-March 1916 {W. J. C. Frost). 



Belongs to the same structure group as leucotcenia, which 

 also inhabits the Key Islands, but abundantly distinct.
