Mr. A. G. Butler 07i the Gemis Terias. 223 



of the " T. senegaleiisis " of Hiibner's ' Zutrage/ fig. 969) : 

 primaries with the costa sparsely irrorated with black scales ; 

 a broad black external border, widest upon the costa, its inner 

 edge running obliquely outwards from the apical third of the 

 mar2:in to the upper radial vein, thence slightly inwards to 

 the third median branch, where it abruptly turns outwards, 

 forming a deep oblique bisinuation as in T. sari^ from the first 

 median to the submedian it forms an angular sinus ; the form 

 of the border in this species therefore is unique : secondaries 

 with pale abdominal border ; the veins black at the extremi- 

 ties and terminating in black spots, which expand upon the 

 margin so as almost to form a continuous line. Under surface 

 like T. hecaheoides. Expanse of wings 41 millim. 



Sierra Leone [Foxcrqft). 



This species should precede T. curiosus. 



Terias rahel group. 



The passage from the T. hecahe group into this is so gradual 

 that it is only by placing in it all species in which there is 

 (in one or both sexes) a more or less defined inner marginal 

 border to the primaries that the group can be indicated ; yet 

 such species as T. zita^ zama, rahel, &c. are so utterly unlike 

 T. hecahe, that nobody could speak of them as belonging to 

 the same group. The following are in the Museum : — 



T. hiformis, Butl. ; T. eumide, Feld. ; T. tilaha, Horsf. ; 

 T. invida, Butl. ; T. Lorquinii, Feld. ; T. alitha, Feld. ; T. 

 rahel, Fabr. ; T. zama, Feld. ; T. zita, Feld. ; and (in the 

 Hewitson cabinet) T. tominia, Voll. 



Terias gr adieus, sp. n. (PI. V. fig. 9.) 

 ^ . Chrome-yellow : primaries with the costal border black, 

 the outer border broadly black-brown, its inner edge com- 

 mencing just beyond the cell and running with an oblique 

 curve to the third median branch, deeply and unequally 

 bisinuated on the median interspaces, then abruptly running 

 inwards and obliquely downwards, so that the lower part of 

 the border fills nearly half the area between the first median 

 branch and the inner margin, the whole length of the inner 

 margin being also somewhat narrowly black : secondaries with 

 broad black-brown border, narrowing towards apex, its inner 

 edge dentate-sinuate, much as in T. alitha from the Philip- 

 pines. Under surface pale dull lemon-yellow with indistinct 

 markings, the outer border narrowly brown and diffused as in 

 T. rahel. Expanse of wings 45 millim. 

 Borneo (from the E. Indian Museum). 

 This species should be placed between T. eumide and T. 

 tilaha, though the secondaries more nearly resemble T. invida.
