Genera and Species o/Pyralidge. 143 



Head, thorax, and abdomen yellow, varied with rosy ; palpi 

 externally dark blackish brown. 



Expanse of wings 12 millim. 



One female from the Khasia Hills. 



In the absence of the male its proper place is dubious ; the 

 labial palpi are long and sharply rostriform, the maxillary 

 palpi also long; the antennse thick, lamellate, slightly 

 pubescent beneath. 



Genus DiATHRAUSTA, Led. 

 Diathrausta profundalis. Led. 



In the typical form, as depicted in Lederer's figure of this 

 insect, the white costal blotch of the fore wings is well 

 marked and has a blunt apex ; the white spots in the fringe, 

 two in the fore wings, and one in the hind wings are pure white 

 and run in quite up to the hind margin, totally obliterating 

 the dark dividing line of the fringes. In the Khasias there 

 occur two forms which differ considerably from the typical 

 one above noticed. In the first, which I propose to call var. 

 conicalis, the ground-colour is not so black, more brownish ; 

 the costal white blotch is thinner and ends in a point, and the 

 pale blotches in the fringe are not pure white and do not 

 obliterate the dividing line, but only interrupt it; besides, 

 both wings are narrower and smaller. In the other, to which 

 the name obliterata may be given, and which is still smaller 

 and as dark as the type form, the costal spot is reduced to a 

 small white patch, and the fringes are dark throughout, 

 besides which, in the hind wings the exterior line, which, 

 both in the type form and in conicalis, is evidently twice 

 bent, in this species runs much nearer the hind margin and 

 nearly parallel to it all the way. 



Genus Diplotyla, Meyr. 



Diplotyla ? albilunata, sp. n. 



Fore wings deep velvety blackish fuscous ; first line at one 

 third, thick, blackish, preceded by a pale fascia, which is 

 distinct and yellow only on the costa ; second line before two 

 thirds, parallel to first, but slightly curved outwards in middle, 

 followed by a yellow fascia, which is broadest on costa ; 

 space between lines velvety black, except costa, which is deep 

 yellow, and semilunar spot beyond discocellular, which is 

 white and semihyaline ; fringe concolorous, but white at anal 

 angle. Hind wings like fore wings, but without first line ;
