38 NOVITATES ZOOLOGICAE XXIII. 1916. 



abdominal margin proximally to this spot tinged with orange ; distal area nearly 

 as on forewing, but with the first silvery line almost straight, scarcely at all 

 interrupted. 



Underside almost unicolorous, markings of distal half very feebly indicated. 



? slightly larger, the violet-grey shades stronger. 



Near Oetakwa River, Snow Mountains, Dutch New Guinea, up to 3500 ft., 

 October— December 1910 (A. S. Meek). Type in coll. Tring Mus. 



82. Heterolocha citrina sp. nov. 



<$ , 35 mm. Face purplish fuscous. Palpus dark fuscous above, orange-yellow 

 beneath. Thorax, abdomen, and legs yellow ; fore and middle legs marked with 

 blackish fuscous, hindleg with reddish. 



Forewing with costa arched, apex rather sharp but not produced ; pale lemon- 

 yellow, with scattered minute greyish strigulae, especially in distal area ; costa 

 suffused with vinaceous at base, minutely dotted with blackish grey throughout ; 

 lines vinaceous; first feeble, except as a rather large costal spot at almost one- 

 fourth ; deeply excnrved in cell and less deeply in submedian area ; cell-mark 

 narrow, vinaceous ; outer line thick, running obliquely and straight from apex to 

 R 3 , very feebly incurved in posterior half, reaching hindmargin beyond three-fourths; 

 accompanied proximally by disconnected blackish marks between the veins, the 

 first four lunulate and strong, the others very small or obsolescent ; a vinaceous 



terminal line ; fringe deeper yellow, with an oblique purple spot at apex. 



Hindicing more whitish, except in abdominal region and posterior half of distal 

 area ; a postmedian band, more purple than that of forewing, tapering from three- 

 fourths abdominal margin to R 3 , anteriorly obsolete ; a blackish grey proximal 

 edging to this band; vague indications of a cell-mark ; terminal line thicker and 

 more diffuse than on forewing. 



Underside with strigulation much stronger, dark purplish ; markings coloured 

 as on hindwing above ; base of forewing suffused ; band of hindwing complete; an 

 elongate cell-mark well developed on both wings. 



Vrianatong, Tibet. Type in coll. L. B. Prout. 



Euctenostega gen. nov. 



Face smooth. Palpus rather short, second joint shortly rough-scaled, third joint 

 smooth, exposed, moderate. Tongue present. Antenna in both sexes bipectinate 

 to beyond two-thirds, the branches long in the c?, moderate in the ¥. Hindtibia 

 in S dilated ; all spurs present. Forewing rather broad, apex moderate, termen 

 smooth, curved, oblique; cell short, DC somewhat curved; SC 1-2 coincident, 

 free, arising from cell, SC 3_5 normal, R 2 connate or stalked with R 1 , M 1 approxi- 

 mated to R 3 . Hindwing with termen rounded ; cell short ; C approximated to SC 

 shortly near base, rapidly diverging, SC 2 just separate from R 1 , R 2 wanting, M 1 

 just separate from R 3 . 



Type of the genus : Euctenostega hypsicgma sp. nov. 



Already' three or four genera of the Stegania group are known in which R 2 of 

 the forewing arises with or close to R 1 , but the new species cannot be referred 

 to any of them. From the African Xenostega Warr. (= Pseudocrocinis Swinh. 

 nov. syn.), which shares with it the pectinate antennae, it differs in the longer third 

 joint of palpus, shorter cells, and in the poiut of origin of SO 1-2 of the forewing.
