280 Mr. E. Meyrick's descriptions, dc. 



Placostola, n. g. 



Head smooth. Ocelli absent. Tongue well-developed. An- 

 tennae longer than fore wings (according to Stainton), filiform, 

 basal joint elongate, without pecten, with a tuft of scales above. 

 Labial palpi long, recurved, slender, smooth-scaled, terminal joint 

 shorter than second, acute. Maxillary palpi very short, drooping, 

 filiform. Posterior tibiae clothed with dense rough hairs above, 

 outer spiu-s half inner. Fore wings with vein 1 furcate, 2 — 5 

 parallel, 7 and 8 stalked, 7 to costa. Hind wings :}, linear- 

 lanceolate, with tooth of scales from bend of costa near base, 

 cilia 3h ; veins 2 — 5 tolerably parallel, 6 and 7 closely approxi- 

 mated towards base. 



Closely allied to Stathmopoda, from which it differs by 

 the basal tuft of antennae. The neuration is identical. 

 To this genus I refer without doubt the Indian species 

 described by Stainton (Trans. Ent. Soc, 3rd Ser., I.) as 

 Gracilaria resplendens ; closely agreeing with mine in 

 appearance and in the structural details given, except 

 that, as the antennae of my specimen are broken in the 

 middle, I cannot verify the statement as to their being 

 longer than the fore wings. The peculiar shape of the 

 fore wings, accurately given in Stainton's figure, is very 

 characteristic of Stathmopoda and allied genera (of which 

 I have many species), and is never to my knowledge 

 reproduced in the Gracilariadce. Probably both Stainton's 

 specimen and my own are females. 



Placostola diplaspis, n. s. 

 5 (?), 8 mm. Head shining white. Palpi, antennae, thorax, and 

 legs whitish-ochreous, femora white. (Abdomen broken.) Fore 

 wings very narrow, broadest near base, gradually narrowed to 

 acute apex ; brownish-ochreous, ferruginous-tinged ; two large 

 shining snow-white transverse blotches, margined with ferru- 

 ginous ; first about one-third, triangular, apex resting on costa ; 

 second about two-thirds, subquadrate, anterior margin convex ; 

 cilia whitish-ochreous, more ferruginous-tinged round apex. Hind 

 wings and cilia ochreous-grey-whitish. 



Aden, Arabia ; one specimen, taken by Mr. G. H. 

 Raynor, in January. Easily distinguished from P. 

 resplendens by absence of white apical spot of fore 

 wings, more triangular first and less triangular second 

 blotches, and pale hind wings.
