8. Nyctipao hieroglyphica tenebrata, subsp. n. 
3 .—Differs from N. hieroglyphica in the complete 
absence of the pale postmedian markings on both surfaces 
of tlhe fore wing. 
?.—Pale markings much reduced, especially on the 
underside ; subapical 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 Hampson’s 
excellent classification in Cat. Lep. Phal. xii. p. 273 seq.) and 
shghtly in the hind wing. 
9. Nyclipao alhicrustata, sp. n. 
2 —1C0O mm. 
Head and body brown, the upperside of thorax strongly, 
of abdomen less strongly, darkened. Fore and middle legs 
predominantly deep brown. 
Fore wing with the colours and pattern arranged asin ¢ 
leucotenia, Guen. (Hmpsn., Cat. Lep. Phal. xii. t. cevii. f. 7), 
but less tinged with ochreous or reddish ; proximal area 
more uniformly dark, the antemedian line (often distinct 
in leucotenia) consequently almost entirely obsolete ; white 
band outside median line broad from SC to beyond R°* 
(5 mm. in cellule 7) ; subterminal white 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. 
Hind wing with white subapical spot longitudinal, not 
oblique ; subterminal otherwise obsolescent, almost parallel 
with postmedian throughout. 
Fore wing beneath with the white submarginal spots 
greatly enlarged, as compared with those of lewcotenza, the 
first (as above) 8mm., the second and third larger than 
above, connected with an ill-defined pale shade proximally, 
those in cellules 5, 4, and 3 very large (9-10 mm.), the 
former two proximally reaching the median line. Hind 
wing beneath with the first white subterminal spot as above, 
the second moderate, the rest present but indistinct, forming 
a nearly straight line, in sharp contradistinction to the 
highly-angled one of leucotenia. 
Key Islands, Jan.—March 1916 (IW. J. C. Frost). 
Belongs to the same structure group as leucotenia, which 
also inhabits the Key Islands, but abundantly distinct.
