 near the coast no examples were to be found.

Zeritis Orthrus, n. sp. (PI. II. fig. 10.) 



Exp. 1 in. 2—3 lin. 



$ . Fuscous-grey, tcith pah grey suh-marginal mark- 

 ings. Foreioing : costa clouded with pale grey from base 

 to near apex ; a transverse sub-marginal stripe, ill-defined 

 and somewhat dentated on its edges, extending from costa 

 to 1st median nervule. Hindwing : betAveen radial ner- 

 vure and anal angle a narrow, sliarply-dentated streak, of 

 which the outward dentations reach the hind-marginal 

 edge upon the extremities of the nervules. Cilia of the 

 ground-colour, irregularly varied Avith pale grey. Under- 

 side. — Hindnnng, and costal, apical, and hind-marginal 

 border of foreioing, very pale creamy-grey, with sub- 

 metallic spots ; the markings generally almost identical 

 loitk those of Z. Ta'ikosama, Wlgrn. Foretoing : the 2 

 spots before middle, below median nervure and its first 

 nervule, smaller and much more indistinct than in Tdiko- 

 sama, the white centre wanting in the inner spot in one 

 example, in the outer spot in the other ; the outer of the 

 two sub-marginal rows of spots better marked than in 

 Ta'ikosama. Hindioing : the fourth row of spots {beyond 

 middle^ obsolete, only represented by some scarcely-trace- 

 able darker clouding, mixed with a few sub-metallic scales ; 

 a rather well-marked hind-marginal row of pale fuscous 

 spots, ending with a black spot at anal angle ; a little 

 before the last-named spot a black dot. 



This Zeritis resembles Z. Leroma, Wlgrn., in its total 

 lack of any fulvous colouring on the upperside, but is 

 easily distinguished by its pale grey markings. The 

 underside colouring, though much paler, approximates to 

 Z. Orthrus to Z. Molomo,Tm\\\ {Trans. Ent. Soc. Lond. 

 1870, p. 373, pi. vi. f 9), but it wants the outermost 

 (fourth) row of hindwing spots found in the latter, as well 

 as the brown clouding between that row and the third. 

 On the whole this new species stands nearest to Tdiko- 

 sama, Wlgrn., both in upperside and underside markings, 

 but the singular colouring of the upperside stripes gives it 

 a very distinct aspect.
