POLYDESMA; PANDESMA; BELCIANA. By W. Warren. 367 



S. olena Swinh. (67f). Forewing dark brown, crossed in outer field by several paler lines; inner and olena. 

 outer lines deep black; the inner waved, curved outwards, approaching subbasal on inner margin; outer line 

 excurved round cell; subterminal line sinuous, the outward elbow in middle nearly reaching termen; orbicular 

 stigma a pure white dot; reniform very large, ringed with black; a row of brown, white edged spots before 

 termen; hindwing with indistinct lines, plain only on inner margin; underside greyish ochreous with brown 

 suffusion; cell of forewing brown, with a quadrate brown mark at end, followed by the pale cellspot ; a waved 

 black outer band, crossing hindwing also on a pale space; a broad black subterminal band. West China. 



S. watanabii Holl. Forewing wood brown, lightest in median area; basal and median areas walanabii. 

 marked by minute dark striae; between them a broadish sharply defined maroon band margined by deep 

 black, and externally sharply toothed near the rise of vein 2; outer line black, irregularly waved and toothed, 

 externally edged by a broad deep brown shade; a black streak along vein 2 from outer line to termen; at 

 apex a subocellate spot of brown, preceded on costa by a brown subquadrate blotch; hindwing dark grey 

 brown. Oiwake, Japan. No known species of Si/pna answers to this description; possibly it should be re- 

 ferred to an Ercheia. 



12. Genus: Polydesina Bsd. 



Tongue present; palpi upturned, the second segment well scaled, the third short; antennae of cf cilia- 

 ted; tibiae without spines; thorax smoothly scaled; wings ample; in the cf the underside of hindwing is clothed 

 with long silky hairs. Type P. collutrix Hbn.-G. 



P. otiosa Guen. (= brevipalpis Walk.) (67 g). Forewing pale brownish fuscous; inner, median, and otiosa. 

 outer waved dark lines arising from black costal spots; subterminal line pale, crenulate, preceded by fuscous 

 suffusion; a series of black terminal lunules; hindwing with similar lines; on the underside the fuscous suf- 

 fusion of forewing is restricted to the costal half, and in the cf the whole of the hindwing is covered with 

 silky hairs, whereas in collutrix the forewing beneath is fuscous from costa to inner margin, and only the 

 base of hindwing beneath in the cf is clothed with silky hairs. Kwei-chow, Western China. 



13. Genus: Pandesnia G 



iien. 



Differs from Poli/desma Bsd. in that the hindwing of cf on the underside is simply scaled, without a 

 bed of silky hair. Larva with the first two pairs of abdominal prolegs rudimentary. Type P. quenavadi Guen. 



P. quenavadi Guen. (= fugitiva Walk) (67 g). Forewing pale to brownish grey; inner, median, and quenavadi. 

 outer lines dark, the outer excurved; the subterminal waved; a terminal series of black dots; stigmata both 

 usually indistinct; hindwing whitish, the outer half brownish grey, with obscurely marked outer and subter- 

 minal lines. This Indian insect, especially common in N. W. India, occurs over the frontier in Kashmir. 



P. anysa Guen. (= terrigena Christ, grandis Stgr.) (67 g). Smaller and paler than quenavadi, espec- anysa. 

 ially the cf cf ; the lines finer and blacker ; the praesubmarginal shade narrower and more broken up ; terminal 

 area beyond it as pale as basal half; subterminal band of hindwing similarly reduced, the terminal area pale; . 

 the ab. sirnilata Moore (67 h) appears to be only a small and dark grey form of the ?; the subsp. sennaa- sennaaren . 

 rensis Fldr. (67 h) is larger and dull sandy grey, with the veins in postmedian area of both wings dark; the sis. 

 subterminal shading still more reduced, especially on the underside of hindwing. Not so common in India as 

 quenavadi, perhaps overlooked; terrigena Christ, from Palestine, Persia, and Java seems to me actually iden- 

 tical with the Indian form; of sennaarensis there are specimens in the Tring Museum from Kerma in N. Sudan, 

 iNakheila on R. Atbara, and Shendi. 



14. Genus: Belciana Walk. 



Tongue present; palpi upturned, the second segment thickened, the third slender, erect; antennae with 

 short ciliations: thorax smoothly but coarsely scaled; abdomen with slight dorsal crests; tibiae without spines, 

 slightly fringed with hair. Larvawith the first two pairs of abdominal prolegs rudimentary. Type B. biformis Walk. 



A genus of rather striking insects, the forewings with more or less green or blue green coloration 

 mixed with brown; hindwings with broad dark terminal border; a considerable number occur in India and 

 the Malay Islands to Australia, often closely resembling each other; two only are recorded from the palae- 

 arctic region.
