29. (351-1) PROSTHESIS, gn. 11. 



(ttp0<r#etftse*ail addition.) 

 Type Prosthesis exclasa, sp. n. 



Aiili'iutfti' with pecten ; c simple, or minutely ciliate, not 

 notched, nor attenuate at the base. Maxillary Palpi short, con- 

 verging. Labial Palpi recurved, reaching above the vertex, 

 closely clothed ; terminal joint shorter than median. Haustelluiu 

 scaled at the base. Head and Thorax smooth. Forewings narrow, 

 elongate, evenly lanceolate : neuratioti 12 veins ; 7 and 8 stalked, 

 to costa. Hindwings nearly as broad as the forewings, acutely 

 lanceolate, the costa straighter than the dorsum : neuration 7 veins 

 (3 and 4 coincident); (^>+4) and 5 stalked; (5 and 7 remote, 

 almost parallel. Abdomen smooth. Legs, hind tibiae moderately 

 hairy. 



This genus agrees with Blastobasis Z., Epistetus Wlsm., and 

 Zenodochium Wlsm. in having 3 and 4 of the hiiidwings coincident, 

 stalked, or connate, with 5. It dift'ers from Epistetus and Zeno- 

 dochium in having a pecten instead of a coiichoidal shield of scales 

 on the basal joint, of the antennae, and from Blastobasis^ with 

 which it agrees in having a pecten on the basal joint, in the 

 absence of a notch. 



57. (3067-1) PROSTHESIS EXCLUSA, sp. n. (Plate LII. fig. 5.) 



Antennae stone- whitish. Palpi stone-greyish, sprinkled with 

 fuscous ; the median joint fuscous on its outer side nearly to the 

 apex. Head and Thorax stone-grey. Forewings pale stone-grey, 

 sparsely sprinkled with fuscous and rust-brown scales ; a small 

 spot at the base of the costa, a narrow fascia at one-third 

 from the base, much mixed with rust-brown and strongly 

 angulated outward on the cell, whence it runs nearer to the 

 base on the dorsum than on the costa ; at two- thirds a rather 

 strong group of fuscous and brownish scales, on the dorsum, 

 is more or less connected by scattered scales across the wing 

 to a smaller costal spot a little nearer to the apex, and these 

 again are more or less connected with each other by a chain 

 of six or seven obscure marginal spots running around the 

 apex ; cilia pale brownish grey. Exp.al. 12-1 4 mm. Hindwings 

 grey ; cilia brownish grey. Abdomen greyish fuscous, with narrow, 

 shining, pale steely grey, transverse bands. Legs stone-greyish, 

 thickly speckled with brownish fuscous 011 their outer sides.
