suffused with grey ; the whole glossy, confused ; whitish cell-mark discernible. 



Hindwing beneatli glossy whitish buff, very slightly tinged with whitish 



at termen. 



St. Jean du Maroni, French Guiana. Tyjjc in coll. Tring Museum. 



This species and percrocea Warr. (Proc. U.S. Nat. Mns. xxx. 465) will pro- 

 bably have to be separated from Tricentra on account of the single areole. 



17. Semaeopus nossis sp. nov. 



S, 22-23 nun. Face and palpus brown, inclining to hazel ; palpus paler 

 beneath, third joint shorter than in caecaria Hb. {Verz. bek. Schmett. p. 502). 

 Vertex and base of antenna white ; antennal ciliation of moderate length, almost 

 sessile. Thorax and abdomen concolorous with wings, the abdomen becoming 

 paler posteriorly. Hindtibia strongly tufted, the inner tuft ochreous brown, 

 not — as in caecaria — mixed with red ; tarsus nearly as in caecaria. 



Wings shaped about as in caecaria. — Forewing with SO'- from cell ; cinnamon, 

 the proximal and median areas minutely but rather thickly irrorated with 

 smoke-grey ; lines darker smoke-grey, not sharp ; antemedian before one-third, 

 excurved in and behind cell, rather strongly angulated inward on Jl and SM' ; 

 postmedian less strongly denticulated than in caecaria, less deeply incurved pos- 

 teriorly ; subterminal dots somewhat as in caecaria, but not accompanied by 

 spots ; spots between these and termen in anterior half of wing and near tornus 

 about as in caecaria ; cell-ring small, blackish, with white pupil ; terminal dots 

 elongate. Hindwing similarly coloured and marked. 



Underside paler, with shadowy markings. 



Ciudad Bolivar, Venezuela (S. M. Klages), June 24th, 1898 (type), August 

 lljth, 1898 (paratype, slightly more reddish in tone), both in coll. Tring Museum. 

 2 ?$ in coll. British Museum, also from Venezuela (Dyson, 1847) are larger 

 more heavily marked. 



18. Semaeopus subrubra dominicana subsp. nov. 



?, 24-25 mm. Rather smaller than s. subrubra Kaye (Tr. Enl. Soc. Lond. 

 1901, p. 148, t. 6, f. 19), from Trmidad. Ground-colour more mixed with 

 orange or rufous — varying from hazel towards vinaeeous-rufous — more uniform ; 

 postmedian line less strongly dentate ; termen with fine dark dashes instead of 

 the dots. 



Dominica, 3 V? in coll. Tring Museum. 



Possibly a separate species. Labelled by Warren (MS.) Dichromatopodia 

 pallida ab. purpurata, but has no connection at all with S. pallida Warr. 

 (NoviTATES ZooLOGiCAE, ii. 94), from the Amazons. As it is less purplish than 

 s. subrubra I feel obliged to depart from my ordinary practice of utilising 

 available manuscript names. 



19. Semaeopus pustulata aurantirufa subsp. nov. 



33 mm. The " deep yellow " (almost clear orange) of p. pu.slulata Warr. 

 (NoviT.\TE.s ZooLOGiCAE, xl. 182), from S.E. Peru, changed to ochraceous-rufous 

 or orange-rufous, the discal rings considerably reduced in size. Dark dorsal 

 patch on abdoiien weakened. 



Costa Rica ( \V, Schaus). Type, Sixola River, March, in coll. Tring Museum.
