2 NOVITATES ZOOLOQICAE XXIII. 1916. 



2. Heteralex aspersa albescens subsp. nov. 



c??, 40-42 mm. Larger and much clearer white than H. aspersa aspersa 

 Warr. from Burma and the Malay Peninsula, the discal and terminal dots stronger, 

 thus superficially recalling the pale forms of H. rectilineata Guen. 



Hainan: Wnteryang (type) and Mount Wuchi, May 1903, in coll. Tring Mus. 

 Also from Formosa. 



3. Heteralex unilinea (Swinh.) 



Epidesma unilinea Swinh., TV. Ent. Soc. Lond. 1902, p. 640 (Tasmania, in err.). 

 Heteralex aspersa part. Prout. Gen. Ins. fasc. 104, p. Gl (Hong-Kong). 



I find that II. unilinea Swinh., from Hong-Kong and Hainan, whicli I have 

 hitherto sunk to aspersa, is a distinct, though exceedingly similar species, with 

 the ? antenna shortly bipectinate (in aspersa merely serrate), the termeD of forewing 

 slightly more convex, its line not quite so oblique, hence reaching costal margin 

 1 or 2 mm. before the apex ; the discal dot of the hindwing better developed. 



4. Derambila candidissima sp. nov. 



t? ?, 20-32 mm. Head white. Palpus white, tipped with fuscous, a fuscous 

 spot at end of first joint. Antennal ciliation moderately long. Thorax, abdomen 

 and legs white, the hairs beneath abdomen and in hindtibial pencil partly light 

 ochreous brown. 



Foreiving pure, glossy white ; lines blackish fuscous, composed of moderately 

 large vein-dots ; antemedian with the dot on M farthest from the base ; postmedian 

 fairly straight from SC 5 at 2"5 mm. from termen to M 1 at 3 mm. from termen, and 

 again from M 2 at 4"5 mm. from termen to hiudmargin, the dot on SM 2 slightly 

 enlarged, more or less confluent with one at hindmargin ; discal dot large, triangular 

 (as in extreme zincaria) ; subterminal line greyish, shadowy, very slightly inter- 

 rupted at each cell-fold ; terminal black dots sharp. Hindwing with SC 2 not 



stalked ; without first line, cell-dot small, postmedian line rather more noticeably 

 sinuous than on forewing. 



Underside much more weakly marked, excepting the cell-dots. 



Darupier Island, February and March 1914 (Meek's expedition), type in coll. 

 Tring Mus. Also from Rook Island, Astrolabe Bay (German New Guinea), Kumusi 

 River (N.E. British New Guinea), and Goodenough Island, in the same collection. 



5. Derambila rectiscripta sp. nov. 



Closely related to clentifera Moore (= efila Swinh.), but with rather longer 

 c? antennal pectinations, and distinguishable at a glance by the broader, less 

 interrupted postmedian line of the forewing ; this runs straight from the black 

 spot on R 1 to the middle of hindmargin, not sinuate as in dentifera ; the brownish 

 spots close to termen are likewise rather better defined than in that species, and 

 the postmedian line of the hindwing ends in a more sharply blackish (though 

 smaller) inner-marginal spot. 



Kapaur, Dutch New Guinea, low country, December 1896, type in coll. Tring 

 Mus. Also from Ron Island and the Kei Islands, and in my collection from 

 Kabroor (Aru Islands) and Fak-Fak (Dutch New Guinea). 



Both rectiscripta and dentifera have hitherto been confused with satelliata
