SOME UNDESCRIBED RHOPALOCERA FROM SIAM. 181 



B. M. Type No. Rh. 127, 2, Me Song forest, Prae, N. Siam, 

 April 1918. 



Readily distinguished from typical drumila by the complete- 

 ly grey hind wing and the greatly increased grey -brown suffusion of 

 base of forewing. 



Lyclenesle. 



15. Talicada metana, sp. nov. 



(Plate VI, fig. 4.) 



2. Upperside, botJt ivings. — Dark sooty brown, the fringes 

 chequered black and white. Forewing. — -Costal edge finely marked 

 with white. Hindwing. — A broad orange band extends from anal 

 angle to just short of vein 6, its inner edge slightly concave, its outer 

 edge bounded in areas 16 and lc by a very fine black marginal line, 

 and in areas 2, 3 and 4 by basally contiguous triangular black marks 

 the apices of which project into the orange. 



Underside, both wings. — White, fringes as above. Fore- 

 wing. — A heavy black mark crosses cell-end ; beyond this, and 

 rather more than half-way to hind-margin, there is a transverse 

 series of six heavy black roundish spots, in areas 16 to 6, curving 

 slightly so that the spot in area 2 is nearest the base, that in area 4, 

 which is also the longest, is the furthest removed and in fact fuses 

 with the corresponding spot in the antemarginal series. This latter 

 series consists of a complete row of black triangular spots, their bases 

 much fused together, their apices produced along the veins as lines 

 which extend to the very narrowly black margin. In each of the 

 white spots of ground-colour so enclosed there is a small black lunule 

 close to the margin, those in areas 16 and lc together forming an ob- 

 long mark proximal to which the enclosed white area is sprinkled 

 with orange. Hindwing. — Arrangement of markings similar to that 

 of forewing but the spots of the antemarginal series, except in areas 6 

 and 7, orange not black, the inner edge of the series very wavy, the 

 enclosed spots of the marginal series increasingly larger from costa 

 towards anal angle, but at anal angle smaller and partly orange. The 

 black spots of the post-discal series much smaller than those of 

 forewing, especially in areas 16, 3, 4 and 5, where they are reduced
