214 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxxiii. 



Forewings grayish white, suffused and sprinkled with brownish 

 fuscous; the central portion of the wing, on which is exhibited a dark 

 discal shade-spot and another at the end of the cell is less overclouded 

 with fuscous sprinkling than the margins or apex of the wing; a little 

 beyond the discal spot is an elongate dark streak in the fold, and a 

 dark shade at the end of the fold is a little less obliquely placed in 

 relation to a spot at the end of the cell; the apex and termen show 

 slight pale interruptions in the dark shading, which gives the appear- 

 ance of a series of ill-defined marginal shade-spots extending through 

 the whitish gray cilia; the whole wing has thus a mottled and speckled 

 appearance, the white ground-color showing chiefly before and 

 beyond the discal spot, and in two rather oblique marks pointing to 

 the fiexus beneath the basal half of the fold.

Family STENOMATID.E. 



=Xyloryctidie Dyar, Bull. U. S. Nat. Mus., No. 52, 1902, pp. 518-9. 



Allied to Xyloryctidse Meyrick, but differing in having veins 7 and 

 8 pi the forewings separate. 



This family is characteristic of tropical America, but would include 

 Agriophara Rosenstock'^ (the only Australian genus with veins 7 and 

 8 of the forewings separate referred by Meyrick to the Xyloryctidse) 

 and a few Indian forms. 



The species belonging to various genera of the Stenomatidse have 

 been generally erroneously described as " CryptolecMa" (OecophoridaO 

 which genus differs in having 7 and 8 of the forewings stalked, and 6 

 and 7 of the hindwings separate and parallel. 



MENESTOMORPHA&, new genus. 



Type of the genus. — Male of Menestomorpha oblongata Walsingham. 



Antennse biciliate (2^). 



Maxillary palpi rudimentary. 



Labial palpi recurved, median joint of even width throughout, 

 closely clothed; terminal joint rather more than half the length of 

 the median, reaching above the vertex, acuminate.
