zigzag line, which consists of four partitions being distally dentate n[)on M and 

 SM- and j)roximally upon (SM'), and by a snbbasai line, which is distinct only 

 ])chind cell ; a double stigma, the upper dot minute ; on the disc there are two 

 parallel, somewhat S-shaped, slightly lunulated lines, followed by an indistinct 

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

 internal margin, reaching the latter about 2 mm. from angle, the lunules composing 

 it convex distally; parallel with it is a heavy, band-like line, which is marginal from 

 M' to anal angle ; an indistinct apical dasli, followed behind SO' by a curved line ; 



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



.'tf/f/fa, dentate externally, not reaciiing 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 tlie 

 Ibrewing, discal lines as in the allied species. 



5. Tenth segment (PL XLII. f. 12) resembling that represented by 

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

 ending in a short tooth. Harpe (PI. XLVII. f 4) produced into a short, jiointed 

 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 tip of the same, whip ratiier shorter 

 than in the following insects (Jasca, etc.).

361. Perigonia pallida spec. nov. 

 cJ?. Similar to s^«/^«, 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 

 than in stidf". 



6. Tenth 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 i)late (PI. XLI. f. 4) broadly rounded ; mouth of vagina postmedian, 

 the edges raised, the proximal edge sinuate mesially.
