222 ]\rr. A. G. Butler on the Genus Terias. 



Terias bidens, sp. n. (PI. V. fig". 7.) 



? . Lemon-yellow : primaries with the base and costa irro- 

 rated with blackish scales ; external border occupying nearly 

 half the wing, confluent with a costal stripe which commences 

 at basal fourth and gradually widens to just beyond the cell, 

 where it meets the external border ; the inner edge of the latter 

 crosses the wing transversely from this point to the third 

 median branch and then is interrupted by two unequal tooth- 

 like sinuations, beyond which it is again continued with a 

 slight inward curvature to the inner margin ; the border below 

 the bisinuation is about one fourth narrower than above it : 

 secondaries with the external border about twice as wide as 

 in T. hecabeoides ? , its inner edge deeply dentate-sinuate. 

 Under surface as in the preceding species, excepting that there 

 is an irregular transverse streak of subapical brown spots on 

 the primaries, as in species of the T. cesiope group. Expanse 

 of wings 49 millim. 



Sumatra. Colls. Hewitson and F. Moore. 



Also somewhat allied to T. diversa. 



Terias semifusca, sp. n. (PI. V. fig. 8.) 



? . Dull lemon-yellow : primaries with the costal margin 

 narrowly black ; base and costa irrorated with blackish atoms ; 

 external half chocolate-brown, its inner edge not sharply de- 

 fined but commencing opposite to the end of the cell, crossing 

 the wing transversely to second median branch, then falling 

 obliquely outwards so as to form a shallow sinus on the first 

 median interspace and thence again obliquely outwards to 

 submedian vein and inwards to inner margin : secondaries 

 with the external third occupied by an internally diffused 

 chocolate-brown border ; fringes yellow, that along the exter- 

 nal border of primaries reddish. Wings below clear lemon- 

 yellow, with markings as in T. hecabeotdesj excepting that 

 there is an indication of a brownish biangulated, subapical, 

 transverse streak on the primaries. Expanse of wings 

 45 millim. 



Sumatra [Wcdlace). Coll. Hewitson. 



Also belonging to the T. diversa group. 



The three preceding species were in Mr. Wallace's collec- 

 tion, and, considering that he thought T. diversa sufficiently 

 distinct to be separated from T. hecabe, it is to me incompre- 

 hensible how he could have persuaded himself that these far 

 more distinct forms were varieties of the latter species.
