DINDIOA; SPHAGNODELA; PSEUDOTERPNA. By L. B. Prout. 13 



bluish scales, the postmedian repandate at third radial. Hindwing bright orange-yellow, the base and most 

 of inner margin fuscous, some fuscous speckling at distal margin, an unusually large blotch at end of cell, 

 a broad, shghtly interrupted band before distal margin. Under surface of both wings yellow, nearly white 

 at distal margin, large dark cell-patches and very broad submarginal bands (on forewing touching the margin 

 in places), besides some grey speckling and an obscure grey cloud occupying most of posterior (inner) margin. 

 Originally described from Bengal, occurs also at Yatung, Tibet. 



T. davidaria Pouj. (3 c). which I have not seen, is possibly a form — certainly a very close relative — of ckividaria. 

 the preceding, closely approaching the form molleri Warr. from Sikkim, but with the black markings of 

 hindwing and underside still further reduced, in particular almost wanting at the margins. Mou-pin. 



5. Genus : Diiitlica Moore. 



Related to Terpna through such species as leopardinata, but at once distinguishable by having a dense 

 tuft of projecting scales from the frons, an enormously developed metathoracic tuft, and the crest on the fourth 

 abdominal segment unusually strong. As with all the preceding genera of the subfamily, the true home of 

 the present genus is India. The single Palearctic species shows the special generic characters somewhat less 

 highly developed than in its relatives, but its systematic position is not open to doubt. 



D. virescens Btlr. (= koreana Alph.) (1 g). Forewing olive-brown, slightly of strongly and coarsely virescens. 

 speckled with fuscous and with a faint reddish suffusion about the discal spot; antemedian hne very oblique 

 and deeply dentate, postmedian obhque from costa to near distal margin on radials, thence strongly retrac- 

 ted; antemedian hne accompanied proximally and postmedian distally by reddish clouding. Hindwing paler, 

 with broad dark marginal band. Underside of both wings nearly as hindwing above, forewing with large 

 cell-spot. Japan and Korea, occiirring from July to September. 



6. Genus: !Sp]iag^no<lela Warr. 



Palpus with third joint small. Antenna in cJ Avith rather short, clavate pectinations. Metathorax 

 shghtly crested. Abdomen crested. Forewing with first subcostal anastomosing with costal. Hindwing 

 with costal approximated to subcostal as far at least as to middle of cell, second subcostal usually short- 

 stalked with first radial. 



The genus contains only a single species, which has a somewhat restricted range in North India and 

 Tibet. 



S. lucida Warr. Forewing yellow-green (probably richer moss-green when absolutely fresh) coar- lueida. 

 sely speckled with fuscous. Lines thick, lunulate-dentate, the postmedian repandate at third radial. Some 

 whitish submarginal spots between the veins, accompanied irregularly by larger fuscous spots. Hindwing 

 much paler, only the distal margin concolorous with forewing. Underside of hindwing nearly as upper, of fore- 

 wing clouded nearly throughout with dark greyish. Sikkim to Tibet. 



7. Genus: Pseudoterpua Hbn. 



Palpus with third joint short. Antenna in c? shortly pectinate. Abdomen crested. Forewing with 

 first subcostal vein usually free. Hindwing with costal approximated to subcostal to nearly one-half the 

 length of the cell. Base of costa of hindwing very slightly expanded, frenulum in $ consisting of only a few, 

 long hairs. Larvae moderately stout, rigid, nearly cylindrical, with shght lateral flange, skin-surface strongly 

 shagreened, tubercles and setae very small. Feed on species of Genista and allied Papilionaceae. — Pseudo- 

 terpna is the first essentially Palearctic genus of the subfamily, occurring from Europe to Armenia and 

 N. W. China. It is probably descended from Pingasa, but lacks the raised scales on the wings, has quite 

 different palpus, different course of costal vein of hiiadwing, and especially shows the commencement of the 

 basal costal expansion and weakening of frenulum which are characteristic of so many of the succeeding ge- 

 nera of the Hemitheinae. 



P. pruinata Hufn. (= prasinaria Fab. = cythisaria Schiff. = genistaria Vill) (1 f). Green, sometimes pminaia. 

 more, sometimes less bluish, mixed with whitish, the forewing with two, the hindwing with one dark green 

 transverse hne, varying in intensity and in exact position; submarginal hne thick, whitish. — ab. agrestaria agrestaria. 

 Dwp. is nearly unicolorous, the dark hnes being entirely effaced. It possibly tends to form a local race in
