Heterocera in the Joicey Collection, 317 



a smoky admixture ; fore wing with a large black cell-spot, 

 hind wing with a black dot. 



Maevatanana, Tananarive district, Madagascar, 2 $ $ . 



It is not altogether impossible that this may be the $ of 

 concolora, Swinh. (Ann. & Mag. Nat. Hist. (7) xi. p. 503), 

 described from the ? only, but it seems very improbable, 

 as that has broad wings, the second joint of palpus more 

 extended black above, the tarsi and spurs black, &c. 



8. Nyctemera pellex frosti, subsp. n. 



S .—40-43 mm. 



Fore wing with the white spots reduced in size ; the 

 elongate white hind-marginal streak reduced to a small spot 

 (1 or 2 mm. in length) at 5 or 6 mm. from base. 



Hind wing with black border strongly broadened (as in 

 some aberrations of pellex separata, from the Northern 

 Moluccas) ; abdominal margin broadly grey-black, this shade 

 extending at least to the fold, and proximally encroaching 

 so as even to enter the cell ; the black at costal margin 

 shaped as in pellex separata. 



Kei Islands, Dec. 1916-Feb. 1917 (W. J. C. Frost), type 

 <$ and another. 



9. Nyctemera luctuosum rostrigera, subsp. n. 



? . — Forewing with the white subbasal patch behind the cell 

 enlarged, reaching posteriorly to SM 2 , thus only separated, 

 in its distal part, from the hind-marginal white streak by a 

 line along SA1 2 ; postdiscal white band in general somewhat 

 narrowed ; a beak-shaped white projection outward from this 

 band between K 1 and ft 3 , as in galbanum, Swinh.; fringe 

 sometimes whitened towards toruus. Hind icing with the 

 white in the fringes more or less extended. 



Philippines : Cebu (J. J. Mounsey) , type ? and another ; 

 Mindanao (ex Semper), two ? $ . 



This is certainly the luctuosum of Semper (compare 

 Schmett. Philippineu. p. 492, pi. lviii. fig 1), but I am 

 by no means certain that it is not a distinct species or 

 possibly a dimorph of galbanum, Swinh., wanting the 

 characteristic white spot in cell of fore wing ; compare the 

 remarks of Semper (/. c.) under that species, though gal- 

 banum is certainly not the Luzon i*epresentative of luctuosum 

 (rostriger'a), for the Joicey collection possesses three typical 

 galbanum from Cebu.
