26 NOVITATES ZOOLOGICAE XXIII. 1916. 



(slightly less narrow), but more gibbous hiudwing, and further differs in having a 

 smaller cell-mark, larger antemedian and postmedian spots, not so strongly con- 

 fluent into lines, and restricted subapieal mark like that of argentipuncta. 



Mount Goliath, Central Dutch New Guinea, about 139° E. longitude, 5000- 

 70O0 ft., January 1911 (A. S. Meek). Type in coll. Tring Mus. 



58. Pomasia amplificata interrupts subsp. nov. 



Differs chiefly from name-typical amplificata Walk. {List Lep. Ins. xxii. 658) 

 in having the postmedian band of the hindwing interrupted, a streak of the ground- 

 colour running oat between R 3 and M 1 to join the subterminal ; a spot at the 

 bifurcation of R 3 -M' stands well isolated from the patch at middle of abdominal 

 margin.

Bihastina gen. nov. 



Face smooth. Palpus short and slender. Tongue present. Antenna in <$ almost 

 simple, with extremely minute ciliatioti. Femora glabrous. Hindtibia with all spurs 

 developed. Forewing with costa almost straight, apex acute, teroien curved, with 

 pointed teeth at SC ä , R 1 , R 3 and the medians, small rounded excisions between — that 

 between R 1 and R 3 the deepest; cell not quite one-half; areole doable, SC 1 from 

 well before apex of distal areole, R 1 stalked or connate with SO 3-5 , M 1 separate. 

 Hindwing with termen toothed at the same veins as the forewing and at tornus, the 

 excisions deeper, that between R l and R 3 profound; cell short; C anastomosing to 

 near end of cell, SO 2 stalked, R 2 from before middle of DC, M 1 separate. 



Type of the genus : Bihastina albolucens Prout, sp. nov. 



Differs from Hastina in the donble areole and point of origin of SC 1 of the 

 forewing ; from Asthena in shape. 



59. Bihastina albolucens sp. nov. 



c?, 27 mm. Face with rather more than one-half white, the upper part olive- 

 brown. Palpus olive-brown, pale on the inner side. Vertex and base of antenna 

 white, a slender olive transverse streak near posterior extremity of head. Front 

 of collar white. Thorax and abdomen white, strongly mottled dorsally and more 

 faintly ventrally with olive; anal extremity white. 



Forewing somewhat iridescent white, the opaque veins purer white ; markings 

 dark greyish olive ; a small basal patch, darkest at costa, otherwise mixed with 

 white except at its sinuous edge ; two sinuous lines (markedly incurved in sub- 

 median area) follow, broader anteriorly than posteriorly, arising from dark costal 

 spots and darkened where they cross M and SM 2 ; a very faint line midway between 

 the outer of these lines and median area ; median area bounded proximally by a 

 rather weak, slender, curved, crennlate line, which arises from a large costal spot 

 and is most distinct on the veins, and distally by two broad lines, between the veins 

 more or less confluent, the outer of them enlarged at the costa, both following about 

 the same course as the termen ; a minute cell-dot not far beyond the antemedian
