27. NiGRAMMA QUADRATiFERA Wlkr. eusema subsp. n, 



9 36 mm. 



Head, patagia and prothoracic crest orange-brown shaded 

 with chocolate, contrasting with the rest of the thorax and 

 tegulae, which are violet-grey with only a few chocolate scales 

 intermixed, the patagia and tegulae more broadly-scaled than 

 in typical quadratifera, Nigranima quadratifera Wlkr., Spec. 

 Lep. Ins., xxvii, p. 77, 1863, Ceylon, with much more of 

 the metallic blue sheen which is occasionally present on a 

 few scales on the thorax and fore wing of typical specimens. 

 Fore wing more purple-grey than in the majority of typical 

 quadratifera, with some chocolate-brown shading on the 

 rounded orbicular and reniform stigmata and on each side of 

 the subterminal line, and with oblique brown bars from the 

 costa to the two stigmata. Orbicular rather better developed 

 than in typical quadratifera. Terminal black spots on both 

 wings rather broader than in the type-form. Under surface 

 darker, the termen of hind wing almost as dark as the 

 postmedial line, the fringe rather more darkened. 



Mt. Murud, 7200 feet, November— 1?. 



In spite of the fact that only a single 9 from Sarawak 

 is known to me the general appearance is so distinct from 

 that of other specimens which I have seen that it has seemed 

 safe to regard this as a distinct race from quadratifera 

 quadratifera, which appears to be confined to Ceylon, where 

 it is not uncommon. 



28. Gyrtona semicarbonalis Wlkr. 



Gyrtona semicarbonalis Wlkr., Spec. Lep. Ins., xxvii, p. 92, 1863, 

 Sarawak. 



Mt. Murud, 6000-6500 feet, November— 2 cf , 49 ; without 

 exact elevation, November — 19 , 2 cT ; without date — 1 cf . 



An exceedingly variable series, but all agreeing in shape, 

 in the hind wing and in the very characteristic subterminal 

 dark spot in fold of fore wing. Two or three specimens 

 belong to the typical form of semicarbonalis , and it seems 

 probable that all are aberrations of one species. 



A not common species, recorded from Ceylon, Perak, 

 Singapore, Borneo, and New Britain. A series of specimens 

 in Coll. Joicey from Cent. Ceram may also have to be 

 referred to this species,
