INDIAN MICRO-LEPIDOPTERA. 161 



with tufts of scales, 2 and 3 remote, 6 to apex or termen, 7 and 8 stalked, 

 or 7 and 8 out of 6, or rarely 7 absent. Hindwings elongate-trapezoidal, 

 termen beneath apex more or less bisinuate, oblique ; 3-5 more or less 

 approximated at base, 6 and 7 stalked. 



I have extended the essential characters of this genus as above ; from 

 a careful study of considerable xiiaterial I am convinced it is justifiable. 

 It is exceptional to find the origination of veins 7 and 8 of forewings 

 out of 6 an iiasuflicient character for generic distinction from forms 

 with 6 separate (though the origination of 6 from the stalk of 7 

 and 8 is seldom if ever of generic value), but in this instance the 

 transition is practically complete, vein 6 in certain forms being very 

 closely approximated to 7 ; the reason seems to be due to the frequently 

 apical termination of 6 (an unusual structure). By this extension of 

 characters the Australian and African genera Allocota, Deuteroptila, Semo- 

 (lictis, and Cymatomorpha become synonyms of Chelaria. The species are 

 often very similar in general appearance, and the structural distinctions 

 must therefore be carefully noticed ; a tabulation into groups based on 

 these is given below, which may assist determination. Besides the 

 seventeen species described here there is another, indica, Wals., which I 

 have not yet been able to identify.

Chelaria anyuinea, n. sp. 



S . 16 mm. Head and thorax whitish, irrorated with grey and fuscous. 

 Palpi whitish irrorated with grey and dark fuscous, second joint with two 

 moderate rounded tufts beneath tinged with ochreous, terminal joint 

 with median band of dark fuscous suffusion and strong median projection 

 of scales posteriorly. Abdomen whitish irrorated with grey and dark grey. 

 Forewings elongate, very narrow, costa gently arched, with scales rather 

 prominent at %, apex round-pointed, termen extremely obliquely rounded; 

 7 and 8 out of 6 ; scattered tufts of scales, and a large tuft on fold at 'I 

 of wing ; light brownish irrorated with white, and irregularly sprinkled 

 with dark fuscous ; a short black dash beneath costa near base ; a narrow 

 dark fuscous patch extending along costa from i to f , cut by two oblique 

 white striguloe ; some indications of irregularly scattered small undefined 

 dark fuscous marks ; two or three black dashes towards apex : cilia grey 

 irrorated with whitish. Hindwings pale grey, paler and thinly scaled 

 anteriorly ; cilia whitish-ochreous. 



Khasis ; in May, one specimen. 



Chelaria laetifera, n. sp. 



S . 14 mm. Head and thorax ochreous-whitish, patagia brcwn. Palpi 

 whitish, second joint with long rough projecting basal and apical tufts 

 beneath and ochreous-brown bands sometimes sprinkled with blackish 

 traversing these, terminal joint with indistinct fuscous oblique subbasal 

 and median rings, and projecting scales posteriorly towards middle. 

 Abdomen dark grey, anal tuft ochreous-whitish. Forewings elongate, 

 narrow, widest at J, costa gently arched, apex pointed, termen extremely 

 obliquely rounded ; 6 separate, to apex, 7 and 8 stalked ; chocolate-brown, 

 becoming deeper towards costa and apex ; an ochreous-whitish patch
