10 NOVITATES ZOOLOGICAE XXIII. 1916. 



23. Aeolochroma prasina angustifascia subsp. nov. 



c?. Differs from name-typical prasina Warr. in having the median band of 

 the forewing narrowed (posteriorly 2 mm. against 3 or 4 mm.), postmedian line 

 (especially of hindwing) much less indented between SC 5 (S(J 3 ) and It 1 , discal spots 

 enlarged, forewing beneath with the black border strong, hindwing beneath with 

 strong blackish clouding in submedian area proximally to the postmedian line, the 

 black border very strong, narrowing suddenly on reaching submedian fold. 



?. Band of forewing less narrowed, obsolescent anteriorly; forewing, except 

 basally and costally, and entire hindwing with dull purple suffusions, more recalling 

 albifusaria Walk. ab. (? subsp.), suffusa Warr. ; postmedian line as in <J ; under- 

 surface not more suffused than in. prasina prasina, discal spots large. 



Dampier Island, February— March 1914 (Meek's expedition). Type in coll. 

 Tring Mns. 



24. Aeolochroma albifusaria (Walle). 



$ . Boarmia albifusaria Walk., List Lep. Ins. xxxr. 1589 (1886) (Mysol). 



<J. Actenochroma (?) prasina ab. suffasa Warr., Nov. Zool. iii. 283 (1896) (Fergusson Island). 



C?. Aeolochroma suffusa Prout, Gen. Ins. fasc. 129. p. 36 (1912). 



I have seen no example from Mysol except Walker's badly discoloured type, 

 but now that I am acquainted with both sexes in good condition from different 

 parts of Dutch New Guinea I can with confidence sink Warren's suffusa. The $ $ 

 entirely lack the white patches which generally characterise the ? , and this — 

 together with the fact of his having mistaken a rather dark aberration of prasina 

 for the $ to his suffusa — accounts for Warren's and my own failure to discover 

 the synonymy. On the other hand it is still possible that suffusa may prove 

 tenable as a subspecies; although the <$ t$ seem quite indistinguishable, the only ? 

 which I have yet seen from Fergusson Island (the original locality) entirely lacks 

 the white patches of name-typical albifusaria, and the same applies to the ? form 

 from some parts of British New Guinea. But the range of the albifusaria and the 

 suffusa form appears somewhat to overlap in that country, and although I have not 

 yet seen both forms from any single locality, I shall not be surprised if they prove 

 to be mere aberrations. Hitherto the ? has been but rarely taken. 



25. Dysphania numana buruensis subsp. nov. 



<?. Forewing with all the yellow patches white, the postdiscal ones between the 

 radials not materially reduced, the elongate one between R 3 and M 1 (often obso- 

 lescent in the other races) conspicuous ; no pale spot at middle of hindmargin. 



Hindwing with the large discal patch white, the cell-mark not (as is generally the 

 case in numana peregrina Bastelb.) enlarged, the yellow submarginal spots not 

 reduced. 



Kayeli, Buru, March 1897 (W. Doherty). 3 SS in coll. Tring Mus. 



The Obi race, peregrina Bastelb., is sometimes almost equally devoid of yellow, 

 but differs markedly in the reduction of the postdiscal spots ; the subform of 

 peregrina from Morty, Halmaheira and Batjan (albipunctulata Bastelb.) is scarcely 

 worth keeping separate therefrom, but is, curiously enough, slightly intermediate in 

 ■coloration between the Obi form and Cramer's name-type from Ceram and Amboina. 

 I do not think that helenetta Walk. (Ceram) is more than an aberration.
