In both sexes the hind .and inner margin of forcwing arc of equal length, hnt 

 the forewing in the S is narrower, the apex more prolonged, the enter margin 

 more oblique. The hindwing has the inner margin somewhat concave in both 

 sexes : but while the hindmargin in the ? is full}- rounded, in the S it is nearly 

 straight and the anal angle ])rominent, clothed beneath with a bed of rough coarse 

 scales.

T) ? ?,-J (?(?. 



The ? greatly resembles P. M-iittiUans Warr. from Australia, the type of 

 which, however, is a cJ, and both are manifestly related to aiirknulu Bntler, which 

 Meyrick also records from Australia. 



00. Stibarostoma furcata. 



PcrirerafurcaUi, Wiirr., Nov. Ziiiu,. iii. p. 375 (189C). 



I have hitherto only seen 2 ? ? of this species, the type from Moroka, British 

 New Guinea, and a second from Isabel Island. The cJ, an example of which has 

 just come from Upper Aroa River, British New Gninea, collected by Meek in 

 February 1003, has the palpi of Stibarostoma, the hairs above on the thick second 

 joint erect and as it were brushed back. 



Subfamily HYDRIOMENINAE. 

 Aeschrostoma gen. no v. 



Distinguished from all other genera of the Ilijdriomeninac by the structure of 

 the palpi ; all three segments are clothed with a brush of long hairs porrect and 

 slightly drooping, that on the basal segment not reaching so far as the others, the 

 segments themselves being quite concealed ; the frontal tuft is similarly though 

 more shortly clothed ; the antennae (?) are lamellate ; the hindmargin of the 

 forewing is slightly, of the hindwing distinctly, crenalate. The genus is related 

 to Coenocalpe. 



Type : Aeschrostoma marmorata spec. nov. 



01. Aeschrostoma marmorata spec. nov. 



Forewing: whitish, tinged and dusted with reddish; a reddish brown central 

 fascia occupies the middle third of the wing, its outer edge angled outwards below 

 vein 4 and insinuate on the submedian fold, its inner edge indented in cell ; it is 

 crossed by three darker lines edged and dusted with whitish scales, and margined on 

 both sides by a pale band with dark centre ; basal patch reddish, crossed by a pale 

 line in middle; marginal area whitish; snbmarginal line waved, indistinct excejjt 

 where i)receded, at costa, beyond cell, and on submedian fold, by blackish lunules, 

 and followed in each case by a reddish fnscous shade ; a dark festooned marginal 

 line ; fringe reddish with pale base and chequered with dark beyond veins. 



Hindwing: very similar, with a single thick basal line; the dark marginal 

 border broadly interrupted at middle by the pale ground-colour. 



Underside sutlused, except along inner margin, with vinous red ; the cell-spots, 

 the three inner lines, and the subterminal blotches velvety black ; the veins dotted 

 alternately with dark and light. 



Face, paljii, shoulders, and patagia mixed reddish and grey; the thorax and
