Dasychira ampliata^ n. sp. 



5 . White : primaries finely speckled with smoky brown, 

 and crossed by two irregular lunulated belts, the inner one 

 edged with more numerous brown scales, the outer one blackish 

 internally and with a squamose greyish external border ; an 

 ill-defined submarginal greyish squamose belt followed by a 

 slightly undulated black line ; a slender grey marginal line : 

 secondaries suffused with pale smoky brown, excepting upon 

 the costal area : abdomen greyish ; antennge with reddish- 

 brown pectinations. Under surface white, the wings, particu- 

 larly the primaries, clouded with very pale greyish brown, the 

 veins brownish. Expanse of wings 3 inches 7 lines. 



Ellongo, Madagascar. 



This species, in every thing but its antennge and neuration, 

 bears a remarkable resemblance to Lobeza aglone, H.-Sch., 

 from Rio Janeiro ; the likeness is as great as in any recorded 

 ' case of protective assimilation. 



The %gg of D. ampliata is very large, subglobose, smooth, 

 the upper half being coloured with alternate concentric circles 

 of olivaceous and whitish, the lower half snow-white. 



Spidia, n. gen. 



Allied to Drepana^ neuration similar : primaries much 

 broader, the outer margin deeply excavated below the apex 

 and regularly convex from the sinus to the external angle, 

 considerably less oblique ; inner margin much longer : secon- 

 daries with the outer margin almost straight, so that the anal 

 angle is much more acute. Type 8. fenestrata. 



Spidia fenestrata, n. sp. 



Coloration and aspect of Drepana scabiosa, excepting in 

 size and form. Brownish grey, with a pearly lustre ; wings 

 divided into two areas by an oblique blackish stripe from the 

 apex of the primaries to the basal third of the abdominal 

 margin of secondaries, the area beyond the stripe darker than 

 the basicostal area : primaries with a hyaline white spot at 

 the end of the cell, and four smaller hyaline spots half encir- 

 cling it externally : secondaries with an abbreviated blackish 

 stripe across the apical third of the abdominal area : body 

 blackish. Under surface pale silvery greyish brown, speckled 

 with black ; hyaline spots as above. Expanse of wings 1 

 inch 9 lines. 



Old Calabar.
