230 MESSES. H. J. ELWES AND JAMES EDWAEDS : 



sex of P. corissa in being a little larger, and in having the hyaline spots in cells 6 and 7 of 

 the fore wing above longer, an oblong hyaline spot in cell 8, and a small irregular yellow 

 spot in cell 5 near the lower outer angle of the spot in cell 6.

IPlastingia similis, n. sp. (Plate XIX. fig. 18, d ; Plate XXIV. figs. 56, 56«.) 



Closely allied to P. noemi, de Nicev., from which it differs in its smaller size, the less 

 conspicuous yellow streak along the basal half of the costa of the fore wing above, and 

 in the particulars set forth in the above Table of Species. 



Expanse 34 mm. 



Hab. Pulo Laut {Doherty). 



Described from one male and two females in coll. Elwes. 



Plastingia submaculata. 



Plastingia submaculata, Staudinger, Iris, ii. p. 149, pi. ii. fig. 8, <$ (1889). 



Fore wing above with two cell-spots, a pale spot in each of cells 2 and 3, and a 

 yellow streak from the base next the upper edge of vein 1 a. Hind wing below yellow- 

 green, the dorsum darker, three black spots near the base, and six others forming a 

 postmedian curved series. 



Hab. Palawan (Platen). 



We have not seen this species, which may not be a Plastingia ; the figure of the fore 

 wing below does not agree with the author's description.

Antenna? (in the male) about two-thirds as long as the costa ; club slender ; arjiculus

 scaled ; third joint minute, acicular or obtuse, almost concealed. Fore wing : termen 

 (in the male) longer than the dorsum, vein 5 nearer 4 than 6, vein 2 from the basal 

 third of the lower edge of the cell, no hyaline spot in cell 4; in calathus, zetis, and 

 mytheca, the base of cell 3 is about twice as long as the base of cell 4, and in zenon, 

 avesta, sarala, and excellens the base of cell 3 is about one-third longer than the base 

 of cell 4. Hind wing : cell less than half the length of the wing, termen very feebly 

 excavated in cell 1 b. Epiphysis present ; hind tibia? fringed and bearing two pairs 

 of spurs.
