B. parallela Leech (75 a). Forewing pale brown dusted with fuscous; inner and outer linos clear pale brown, pamllela. 

 outwardly edged with dark brown, and parallel to each other; area beyond outer line darker brown, with 

 a blackish cloud about middle and a smaller one above it, not always plain; subterminal line pale, sinuous,

 The lines are hke those of B. trilinealis Brent., but the species is larger. 



B. albolinealisLeecA (75 a). Forewing ochreous biown, with throe whitish oblique stripes bordering the black alMinealia. 

 transverse lines ; inner line very oblique, fading out before costa ; outer and subterminal lines oblique, diverg- 

 ing towards inner margin; hindwing pale whitish brown, tinged on basal area with fuscous, and with a broad 

 brown band on outer area; cell-spot blackish. Kiukiang, Central China. 



|B. rectilinea Leech (75a). Forewing brown with slight purplish reflection; inner and outer lines whitish, reclilinea. 

 almost straight, both edged with dark brown ; subterminal line pale, wavy, angulated towards costa and inner 

 margin; a row of black terminal lunules; reniform stigma whitish with an obscure dark outline; hindwing 

 with whitish outer line and wavy, pale, subterminal; terminal lunules black as in forewing. Central and 

 Western China. 



B. ? vestitalis Leech (75a). Forewing pale redbrown, the basal two thirds whitish ; lines black; inner angled vestitalis. 

 outwardly at middle; median broad, bidentate; outer wavy, white-edged, excurved beyond cell, dentate towards 

 inner margin; subterminal wavy, whitish, but indistinct; a black costal dot between inner and median lines, 

 and at end of outer line; reniform whitish, containing a black lunule; orbicular a black dot; hindwing with the 

 lines black, the inner broad, the outer sinuous, white-edged. Moupin, Western China. 



B. ningpoalis LeecA (75a). Forewing fuscous brown ; inner and outer lines very dark brown; the subter- ningpoalis. 

 minal line pale, internally edged with dark brown; the stigmata yellow edged with dark brown, the orbicular 

 quite small, the reniform large; hindwing with two parallel dark lines beyond the middle. From the Snowy 

 Valley, Nitigpo and Chang-yang. 



B. contigua Leech (75 b). Forewing pale brown tinged with greyish ; inner and outer lines fuscous, the inner contigua. 

 wavy, the outer curved beyond cell, and slightly waved; subterminal line pale, wavy, internally shaded with 

 dark; a pale ochreous spot at end of cell; hindwing with an oblique, fuscous median line and an obscure, 

 curved, pale subtermmal. Recorded only from Changyang, Central China. Allied to B. ningpoalis Leech, 

 from which it is separated by its smaller size, lighter colour, and oblique, not curved, inner line on hindwing. 



108. Genus: Sertula Walk. 



Differs from Bleptina Guen. in that the palpi of the <$ are recurved over the vertex to middle of thorax, 

 the second segment being fringed with hair in front and bearing tufts of long hair from the inner side, and the 

 third segment also being tufted; the forewings beneath have a costal fold serving for retinaculum. Type 

 B. dbjudicalis Walk. 



Sect. I. Forewing of £ with the costal fold narrow. 



B. abjudicalis Walk. ( = thyrisalis Walk.) (75 b). Forewing brownish ochreous grey; basal area red brown abjudicate. 

 limited by an oblique ochreous inner line; outer line sinuous from costa to vein 4, there angled and inbent 

 below end of cell to inner margin ; a white lunule at end of cell ; an indistinct sinuous dark subterminal line ; 

 hindwing fuscous grey, with pale waved median and subterminal lines, partially defined by dark ; in the form 

 tumidalis Walk, the median area between the inner and outer lines of forewing is much darker. A South 

 Indian species, recorded by Leech from Omeishan, W. China ; the space between the lines is said to be broader 

 than in Indian examples of abjudicalis; this is likewise the case with dentilinea Hmps. from Sikkim, N. India 

 with which the Chinese form is perhaps more nearly allied. 



Sect. II. Forewing of <$ with the costal fold large and wide.
