speckles. Hindwing fuscons in costal third from base to discal line, the latter 



thin, blackish, not reaching abdominal margin ; rest of wing greyish vinaceons 

 bnfl' ; costal area speckled with black; costal margin rounded at base, then slightly 

 incurved. 



Genitalia : anal tergite narrow, divided into two short slender processes, which 

 are rounded above at the tip ; anal sternite long, gradually tapering to a point 

 On each side of the penis-sheath a long, nearly membranaceous, truncate process 

 covered with minute hairs. < 'lasper much reduced, the distal portion mem- 

 branaceous, being modified into a scent-organ. 



Length of forewing : 25 mm.

50. Adelocephala lanaris spec. nov. 



8 . In shape and colour very close to A. brevis Walk. (1855). Antenna with 

 16 pectinated segments. Forewing less elongate, the distal marginal area wider, 

 the discal line thinner and more distinctly edged with grey ou the proximal side. 

 Hindwing more rounded, especially at the anal angle, the reddish patch smaller. 

 Ou underside the forewing elayish behind, not ochraceous ; a diffuse subcostal 

 fuscous cloud from middle of cell to apical fourth of wing ; apex of forewing and 

 the hindwing more brownish thau in A. brecis, and more speckled with fuscous ; 

 the discal line of hindwing less sharply marked. 



Genitalia quite different : anal tergite compressed, wide in vertical direction, 

 mesially deeply impressed, being bicarinate ; apex sinuate in dorsal aspect, each 

 short lobe irregularly dentiform, the real apical edge being straight ; anal sternite 

 divided into two strongly chitinised, black, triangular plates. ( 'lasper with strongly 

 developed scent-organ, the distal half of the clasper being reduced and mem- 

 branaceous, bearing long wool; inside the clasper a curved lamella, the edge of 

 which is more strongly chitinised and ends in a short thorn, this chitinised edge 

 forming almost a semicircle ; at base of clasper a thorn-like process. Penis-sheath 

 obtusely acuminate ; beneath the sheath two further thorn-like black processes.

51. Adelocephala anthonilis analis subsp. nov. 



3 . Forewing broader than in A. a. anthonilis, the two lines wider apart, the 

 discal line standing farther away from the cell ; wool of the clasper ochraceous, and 

 the long ribbon-like process of the clasper gradually tapering, uot being widened 

 before apex.

52. Adelocephala homoea spec. nov. 



3 . Similar to A. anthonilis ; larger ; body and wings washed with vinaceons, 

 being pale vinaceons bull'.* Forewing more elongate, the hind angle more rounded, 

 the two lines as widely separate at hindmargiu as in A. anthonilis analis, but the 

 proximal line more oblique, reaching costal edge nearer to apex of cell ; costal and 

 distal margins of hindwing less rounded. Anal tergite and the ventral process of
