NOVITATES ZOOLOGICAE XXIV. 1917. 387 



Underside with similar but more sombre (dark grey) markings. 



San Esteban, N. Venezuela, June — August 1909 (S. M. Klages). 8 <J(J, 2 ?? 

 in coll. Tring Museum. 



A slight modification of this species, with the green patch beyond the cell 

 broken into four separate wedges, is figured by Lruce {Biol. Cintr. Amer., Lej). 

 Het. ii. t. 51. f. 6, 7) from Chiriqui as " musivaria H. S." 



25. Trygodes niobe desolata subsp. nov. 



(J 9. Rather browner (less pinkish) than n. niobe Druce (Biol. Centr. Amer., 

 Lep. Het. ii. 106. t. 51. f. 9, 10) ; all the spots small, very pale green. 



Venezuela : San Esteban, July 1909 (S. M. Klages), 3 cJo, including type ; 

 June 1909, 1 ? ; Valencia, 1 ?. All in coll. Tring Museum. 



T. niobe niobe is known to me from different localities in Costa Rica and 

 Peru, and will presumably be found in Colombia and Ecuador. 



26. Tricentra allotmeta spec. nov. 



(J 9, 19-21 mm. Very close to T. airnaria H.-Sch. {Samml. Au.ssereur. 

 Schmett. i. fig. 194 = laciniata Warr., Nov. Zool. xiv. 223, syn. nov.). 



Forexving with costal and distal areas more clouded with grey ; subtcrminal 

 yellow Une finer, placed a little farther from the termen, the interneural yellow 



dashes which run in from the termen longer. Hindwing with the yellow line 



quite differently placed, bending rather sharply at R' and thence running 

 straight across the wing to hindmargin 2 mm. from tornus ; distal area as on 

 fore wing. 



Underside with distal area less clear, showing traces of (or even a moder- 

 ately well developed) pinkish cloud dowii its centre. 



Carabaj'a, S.E. Peru : Rio Huacamayo, 3,100 ft., June 1904, dry season, 

 type (J; La Oroya, Rio Inambari, 3,100 ft., November — December 1905, wet 

 season, 2 SS, January 1906, wet season, 1 $. All in coll. Tring Museum, col- 

 lected by G. R. Ockcnden. 



I do not think this can be a mere aberration of mrnaria, as there is no sign 

 of intermediates ; nor is it likely to be a seasonal form, though the only two 

 La Oroya carnaria wliich I have seen were taken at other periods of the year — 

 September 1904, dry season, and March 1905, wet season. 



27. Tricentra devigescens spec. nov. 



<J, 16 mm. Face light yellowish grey. Vertex and uppersidc of thorax 

 and abdomen concolorous with wings ; underside much paler and more ochreous. 

 Hindtibia with the proximal spur less long than in most species. 



Forewing light seal-brown, inchning to grey ; apical region cream-colour, 

 with shght dark dusting, at costal edge rather more ochreous ; the boundary- 

 Hne between the two colour areas is somewhat lunulatc-dentate and runs from 

 before two-thirds costa fairly straight to termen behind M' ; small white dots 

 on DC- and DC ; fringe cream-colour, dark-spotted opposite the veins in pos- 

 terior part. Hindwing with termen sHghtly sinuate, at least between the 



radials and at tornus ; ground-colour and discal dots as on forewing ; no apical 

 patch ; a lunula te-dentate cream-coloured submarginal line within 1 mm. of
