wliite spots is wanting, these being reduced to minnte dots edged liy Idack scales, 

 the white spot at vein 4, touching the outer line, alone remaining in either wing, but 

 smaller, as is the white discal annnlus of the forewing ; fringe of hindwing yellow 

 throughout, of forewing yellow from vein 4 to 2, the rest fulvous. 



Underside bright straw-colour, in the forewings tinged with yellow and with 

 rufous striae and dots ; a brown apical blotch on forewings reaching to vein 4, and 

 a small upright blotch above anal angle ; cell-spot reduced to a brown speck ; 

 hindwings without striae except along hindmargin ; a brown marginal blotch at 

 middle and anal angle. Thorax, abdomen, tips of patagia, and front of face fulvous; 

 vertex, shoulders, and base of patagia grey. 



Expanse of wings : 44 mm.

aUBFAMILY DEILINIINAE. 



Cacostegania gen. uov. 



Forewings : costa arched at base, then straight ; apex blunt ; hindmargin 

 oblique, hardly bowed, till near anal angle. 



Ilitulwings : broad ; hindmargin well rounded, both angles strongly marked. 

 Antennae in cJ strongly bipectinated ; paljii very short ; tongue and frenulum 

 present ; hind-tibiae with four spurs. 



yeiiration : forewings, cell nearly half as long as wing ; discocellular 

 inangulated ; first median uervule at five-eighths, second at seven-eighths ; lower 

 radial from above centre of discocellular, upper from upper angle of cell ; 7, 8, '■), 

 stalked from close before end; 10 and 11 coincident, anastomosing with 12 and 

 again with S, 9 : hindwings, costal very shortly approximated to subcostal ; 3 

 and 7 well before angles of cell. Forewings with small and inconspicuous fovea. 

 Scaling fine and glossy. 



Type : Cacostegania aiistralis sp. nov. 



Probably the species described by me (Nov. Zooi.. VII. p. 94;, as Parasyncgia 

 rufigrisea, the type a j , from Old Calabar, will, wlien the S can be compared, be 

 found to belong to this genus. 



25. Cacostegania australis sp. nov. 



Forewings : pinkish grey, very thickly sprinkled with small fuscous and 

 reddish scales ; the lines deep red ; inner from nearly one-fourth of costa to one- 

 third of inner margin, bluntly angled outwards in cell and on submedian fold, and 

 inwards on subcostal and submedian veins ; outer, lunulate-dentate, from four-fifths 

 of costa to four-fifths of inner margin, the lunules beyond cell and that on submedian 

 fold nearer the base of wing ; traces of a red submarginal line, mainly at costa 

 and on inner margin ; a red marginal line ; fringe rufous grey ; cell-mark linear, 

 red ; the costal edge also red. 



Hindwings : without first line ; outer line irregularly waved and bent, not 

 dentate, from three-fifths of costa to inner margin shortly above anal angle ; cell- 

 spot obscure ; in both wings the marginal area is deeper tinted than the basal. 

 Face and collar deeji red ; thorax and abdomen coucolorous with wings ; vertex 

 and antennal shaft snow-white.
