Lepiduptera from the Soutli Pacific. 199 



12. Desmohathra acrophfPM, n. s. 



5 , 22 mm. Head, palpi, thorax, abdomen, and legs orange- 

 yellow. Antenna; greyish ochreous. Fore wings triangular, hind 

 margin slightly sinuate, rounded in middle ; bright orange, with 

 small thinly scattered purple-brown strigulae ; these tend to form 

 fine irregular lines at one-third and beyond middle; a purphsh- 

 brown hind marginal band, on costa extending from near two- 

 thirds to apex, attenuated to a point on anal angle ; cilia dark grey. 

 Hind wings moderate, hind margin rounded; bright orange, paler 

 towards anal angle ; a narrow cloudy light purplish-brown hind- 

 marginal band ; a purple-brown discal dot ; lines absent ; strigulas 

 and cilia as in fore wings. 



Possibly this might be a variety of the preceding, 

 with which it was found. 



New Hebrides (Mathew) ; one specimen. 



13. Desmohathra niphoplaca, n. s. 



? , 30 mm. Head, palpi, antennae, thorax, abdomen, and legs 

 dark blackish grey. Fore wings moderate, triangular, costa un- 

 evenly arched, hind margin rounded ; dark blackish grey, with two 

 large transverse oval snow-white blotches, first before middle, 

 second towards apex ; the ground colour lightened on three small 

 subterminal spots near lower half of hind margin ; cilia dark 

 blackish grey. Hind wings moderate, hind margin rounded ; dark 

 blackish grey ; a very large irregular trapezoidal snow-white trans- 

 verse median blotch, nearly reaching inner margin ; ground colour 

 lightened between this and a hind-marginal dark band ; ciha dark 

 blackish grey. 



Solomon Islands {Mathew) ; one specimen. 



Derxena, Walk. 



Face smooth. Palpi moderate, porrected, loosely scaled. An- 

 tenna) rather more than half fore wings, in male filiform, ciliated 

 moderately with fascicles of cilia (2). Middle tibiae with spurs 

 very short, unequal; posterior tibia; in male with spurs wholly 

 absent. Fore wings with vein 6 remote from 9, 12 anastomosing 

 moderately with 11. Hind wings with veins 6 and 7 stallied ; 

 basal enclosed area between 7 and 8 hyaline. 



Differs from the preceding essentially by vein 11 of 

 fore wings being free from 9, and G of hind wings 

 stalked with 7.
