zigzag Hue, which consists oi' foar partitions being distally dentate upon M ami 

 SJP and proximally npim (SBI'), and by a subbasal line, which is distinct only 

 behind cell ; a double stigma, the ui)pei' dot minute : on the disc there are two 

 parallel, somewhat S-shaped, slightly luuulated lines, followed by au indistinct 

 tiiird one ; then comes a lunulated line running straight from the costal to the 

 internal margin, reaching the latter about II mm. from angle, the Innules com]K)sing 

 it convex distally; parallel with it is a heavy, liand-Jike line, which is marginal from 

 M' to anal angle ; an indistinct apical dash, followed behind SG° by a curved line ; 



all these lines blackish olive. Hindwing : a large yellow discal area, nearly as in 



sttilta, dentate externally, not reaching base ; abdominal fold with a yellow distal 

 patch ; marginal area of wing grey before anal angle, marked with a thin line about 

 2 mm. from edge, and a very indistinct one a little farther proximad. 



Underside with the testaceous ground-colour coming through, especially on the 

 forewing, discal lines as in the allied species. 



c?. Tenth segment (PI. XLII. f. 12) resembling that represented by 

 PL XLII. f. 9, shorter, tergite somewhat widened apicad in a lateral view, 

 ending in a short tooth. Harpe (PI. XLVII. f. 4) ]iroduced into a short, jwinted 

 process. Penis-sheath (PI. LIV. f. 6) with two or three teeth at the right side, 

 one at the base of the whip, and two at the tiji of the same, whip ratlier shorter 

 than in the following insects {lusca, etc.).

6 ? . Similar to stulta, paler, wings narrower. First segment of palpus with 

 white lateral line. Distal margin of forewing more broadly rounded in middle ; 

 brown border of hindwing narrower, testaceous in front, disc of a deeper yellow tint 

 tiian in stulta. 



S. Tentli abdominal segment as in stulta. Harpe truncate (PI. XLVII. f. 5) 

 as in that species, but the patch of curved spines above it much more extended 

 than in any other species. Penis-sheath as in grisea, but the whip much longer. 



?. Vaginal jilate (PI. XLI. f. 4) broadly rounded ; month of vagina postmedian, 

 the edges raised, the proximal edge sinuate mesially.
