161. Stenalcidia pulverosa sp. nov. 



Forewings: whitisli, dusted thickly with line dark atoms, giving the wing a 

 mealy appearance; the lines finely black; first curved, at about oue-fourth; second at 

 three-fourths, runs oblicjuely outwards to vein 5, is there bent nearly at right ano-les 

 and runs straight to vein 2, then forms a strong sinus to vein 1 , marked throughout 

 by black dots on the veins; median line obscure, bent outwards round the black cell- 

 spot and closely approximated to the outer line below; submarginal line pale, 

 strongly dentate, with ochreons and fuscous sliading on either side, the costal area 

 on the inner side being broadly dark; a fine dark marginal line, bent in to the 

 marginal spots between the veins; fringe greyish. 



Hindwings: similar, without first line, the median shade straight, the outer 

 line curved from inner margin to vein 0, then dentate. 



Underside dirty whitish, speckled with grey; cell-spots distinct; forewings with 

 dull blackish marginal fascia, broad at costa, narrowed to anal angle, including 

 a whitish apical blotch and another in middle of hindmargin; hindwings with the 

 fascia much narrower. Head, thorax, and abdomen whitish, peppered with grey;

Synecta gen. nov. 



Foreicings .- with costa straight till just before apex, which is bluntly rounded; 

 hindmargin obliquely curved; fovea in J exaggerated, as in IL/mrnnmiitin. 



Hindwings : witli both angles and the hindmargin rounded. 



Antennae of S pectinated to near apex; palpi porrect, short; tongue and frenu- 

 lum present; hindtibiae slightly thickened, with four spurs. 



Xeumdon : forewings, cell half as long as wing: discocellular vertical: first 

 median at one-half or two-thirds, second at five-sixths; the two radials stalked from 

 upper end of cell; 7, 8, 9, stalked; 10 and 11 coincident. Hindwings with first 

 subcostal nervule from, or from jnst before, upper end of cell ; second median from 

 before lower end. 



Type : Si/necta griseola sp. nov. 



Distinguished by the stalking of the two radials; it is an extreme development 

 of H>/mnomimn, in which the lower radial rises from above the middle of 

 discocellular.
