on the interno-median area from the base to the inner margin 

 of the central belt ; a black longitudinal streak interrupted by 

 the reniform spot from the inner line of the central belt to the 

 middle of the disk, where it joins a brown streak on the outer 

 margin ; the costa near apex, a short dash beyond the top of 

 the reniform spot, two subapical streaks, and an apical dash 

 blackish brown : thorax reddish brown, greyish in the centre. 

 Primaries and pectus below pale pinky brown : secondaries 

 and venter stramineous, the venter darker than the wings. 

 Expanse of wings 2 inches 3 lines. 



Darjiling (Lidderdale) . Type B. M. 



Mr. Moore has an example of this species from Singapore. 

 The genus is allied to both Peridea and Olene, but in colora- 

 tion it most nearly resembles Heterocampa. 



9. Plialera stigmigera } sp. n. 



Nearly allied to P. sangana, but the primaries shorter, 

 broader, with large whitish reniform stigma ; the orbicular 

 placed nearer to it and very indistinct ; the inner line of the 

 central belt single and more irregular, rather nearer to the 

 base, base of costa sprinkled with white scales ; the external 

 angle blackish, so that the spots which terminate the discal 

 stripe are somewhat obscured ; the submarginal lunules 

 whitish : body darker, with whiter anal segment and tuft. 

 Under surface greyer, the blackish central fascia of the 

 secondaries angulated at the costal vein. Expanse of wings 

 3 inches 5 lines.

10. Phalera arenosa, sp. n. 



Also allied to P. sane/ana, but the whole ground-colour of 

 the internal half of primaries pale sandy yellow, traversed by 

 the ordinary undulated lines and spots, the costal half much 

 darker, varied with slaty grey in the centre and at apex, the 

 discoidal spots well defined ; the secondaries greyer, with 

 blacker external third ; the head yellowish instead of snow- 

 white ; the body black, with greyish lateral borders to the 

 thorax, and greyish-white bands across the abdominal seg- 

 ments ; anal segment pale cinereous. Primaries below blackish, 

 with the usual pale markings : secondaries sordid white, with 

 an abbreviated oblique crinkled black stripe from the costa to 

 the first median branch ; a dusky discal nebula : pectus black ; 

 the legs with greyish fringes ; venter sordid white, with lateral 

 black bands continued from above. Expanse of wings
