List of Species belonging to the Family Pyralidae 503 



I do not possess the typical seminivea but a var. that even comes 

 closer to it than the specimens from Ceram, and I have little doubt that 

 they will prove co-specific. I see no reason, however, why seminivea 

 and leucophota should come in the genus Orthaga as the neuration is 

 quite different from the type of the genus, 0. equadrusalis Walk., apart 

 from other different characters. In these two species vein 6 of fore 

 wing is shortly stalked with 7, 8, 9 ; 10 anastomoses with stalk of 7, 8, 9, 

 just before the place where 7 comes off the stalk and thus forms a large 

 areole. I do not find this areole in any other typical Orthaga known to me.

PYEALINAE. 



78. Cosmethis talboti sp. no v. 



This species comes very near to Cosmethis zemire Cram, and C. 

 vitialis Hmpsn. From the former it differs in the fore wing having 

 the whole area between antemedial line of zemire and its postmedial 

 patch inclusive entirely filled up with whitish scales, thus forming one 

 white patch, which, however, does not reach quite as far as outer edge 

 of postmedial patch in zemire ; the basal yellowish scales are also 

 much reduced below lower median and there is a blackish bar or 

 elongated spot across it between costa and lower median ; veins also 

 more streaked with whitish and one-third of cilia of hind wings white. 

 From vitialis it differs, judging from the description, in having one 

 broad band instead of narrow antemedial line and postmedial patch, 

 and in the cilia of the fore wings not being white. 



$ . Fore wing and hind wing above and below, abdomen, legs, 

 proboscis, antennae and tip of palpi black, in fore wing and less in 

 hind wing with a bluish metallic sheen ; hairs on thorax, patagia, 

 tegulae, head and palpi deep-chrome (iii) ; abdomen with all segments, 

 except the first, narrowly edged above and more broadly on underside 

 with white scales ; anal tuft of hairs deep-chrome ; femora streaked 

 on outer side with whitish scales and tibia tipped with it ; palpi with 

 the second joint on inner side of upper half and the whole of the third 

 joint black,
