NOVITATEa ZOOLOOICAE XXIV. 19ll 379 



Forewing with SC from cell, R' from before middle of DC ; vinaceous buff, 

 with verj^ fine oHve-grey irroration ; costal edge very finely tufous ; markings 

 nearly as in viridiphga Walk., but with the cell-spot sharp, not elongate, the 

 median hne not succeeded by a dark shade, sinuosities of postmedian rather 



less deep. Hindwing with minute white, finely black-edged cell-spot ; median 



line farther beyond it than in vtridipkiga, slightly curved or bent about M'. 



Forewing beneath pale at base and especially along hindmargin ; costal 

 edge proximally more broadly red than above ; cell-spot and the two Unes 

 beyond present. Hind\ving beneath pale as far as the postmedian line ; costal

9. Semaeopus ladrilla fiavicans subsp. nov. 



(J ?, 34-35 mm. Smaller than I. ladrilla Dogn. {Ami. Soc. Ent. Belg. xxxvii. 

 161= illimitata Warr., Nov. Zool. vii. 156), and essentially different in the 

 colour, both of body and wings, which is yellowish clay-colour above, buff 

 beneath.

 Also from Las Quiguas, in the same district (coll. Brit. Mus. et coll. L. B. 

 Prout). 



Without knowledge of the local conditions, it is useless to attempt to 

 account for the occurrence of this modification of so widely distributed a species 

 in so restricted an area, and we are perhaps deahng with a separate species ; 

 but the agreement, except in size and colour, seems exact, and I have preferred 

 to regard the distinction as racial only. 



10. Semaeopus euthyoria spec nov. 



(J, 28 mm. Face mixed with black. Palpus blackish, beneath ochreous. 

 Vertex and base of antenna strongly mixed with red ; antennal cihation scarcely 

 as long as diameter of shaft. Thorax and base of abdomen above concolorous 

 with wings ; anal end and underside pale. 



Foreu'ing with apex rather blunt, termen curved, httle obhque anteriorly ; 

 SC from cell ; saturn-orange (really orange with thick red irroration^ ; costal 

 edge narrowly dark fuscous or blackish ; Unes dull dark reddish ; antemedian 

 from beyond one-fourth costa to before one-third hindmargin, slender, gently 

 curved ; median firm, only very sUghtly curved, well beyond cell-mark ; post- 

 median from within 3 mm. of apex to 1 mm. from tornus, rather slender, rather 

 deeply lunulate-dentate, between the radials somewhat sinuate inward, the 

 tooth outward at R' very sUght, those at R' and M' rather approximated to 

 the termen ; cell-dot small, white, finely red-ringed ; terminal hne red, inter- 

 rupted by orange-yellow dots at the veins, slightly thickened between ; fringe 



red, with a fine yellow hne at base and an ill-defined one beyond middle.' 



Hindwing with termen full, rounded ; as forewing, but without antemedian line. 



Underside paler yellowish, with hindmargin of forewng whitish, the fore- 

 wing mostly, the hindwing between postmedian hne and termen and more
