Sebiioceros, JSIeyr. 

 Semioceros dirjjsorijcia, Me}^'. 

 I have taken this species also in Ceylon. 



Hyalobathea, n.g. 

 Forehead, flat, oblique ; ocelli present ; tongue well-developed. 

 Antennae two-thirds of fore wings, in male filiform, moderately 

 ciliated (1). Labial palpi moderate, straight, porrected, with broad 

 rough projecting scales above and beneath, attenuated to apex. 

 Maxillary palpi short, filiform, apex somewhat penicillate. Abdo- 

 men in male with valves retracted. Posterior tibite with outer 

 spurs half inner. Fore wings with vein 10 very closely approxi- 

 mated to 9, 11 oblique. Hind wings as broad as fore wings ; cell 

 very short, veins 3, 4, 5 approximated, 7 out of 6 near origin, 

 anastomosing with 8 to near middle ; a small oval perfectly 

 transparent bladder in cell at base (probably in male only). 



Allied to Botys, but immediately distinguished by the 

 transparent bladder at the base of the hind wings. 



Hyalohathra archeleuca, n. s. 

 (? , 20 — 21 mm. Head, palpi, antennae, and thorax light brownish

 bowed, rather oblique ; light fuscous, slightly reddish-tinged, along 

 costa more ochreous-tinged ; lines slender, blackish, rather in- 

 distinct and tending to be interrupted, waved ; first from one- 

 fourth of costa to two-fifths of inner margin, curved outwards ; 

 second from two-thirds of costa to two-thirds of inner margin, 

 forming a small spot on costa, whence it runs obliquely outwards, 

 in middle rather abruptly curved, and sinuate inwards above inner 

 margin ; a small cloudy dark fuscous discal spot in middle ; faint 

 indications of a subterminal line ; cilia whitish ochreous, with a 

 sharply marked dark ferruginous basal line. Hind wings pale 

 fuscous, slightly reddish-tinged ; costa broadly and inner margin 

 more narrowly suffused with pure white ; a tolerably distinct
