termen, inbent between the radials and bcliind i\P ; fringe dark-spotted 

 throughout. 



Underside with distal area of hindwing pale from subterminal line to termen, 

 forewing more a.s above. 



Aroewarwa Creek, Maroewj'm Valley, Surinam, April 1905 (S. M. Klages). 

 Tj'pe in coll. Tring Museum. A second example from La Union, Rio Huacamayo, 

 Carabaya, S.E. Peru, 2,000 ft., November 1904, wet sea.son (G. R. Ockenden), 

 is slightly larger. 



28. Tricentra flavifigurata spec. nov. 



S, 19-20 mm. Face pale straw-colour, spotted with umber ; palpus pale 

 beneath. Vertex and thorax and abdomen above vinaceous, mixed -with 

 umber ; underside straw-colour. 



Forewing with termen very sUghtly concave anteriorly to M', here pro- 

 minent, thence very oblique ; vinaceous, here and there with umbreous cloud- 

 ings, in distal part with some yellow admixture, giving it a vaguely oUvaceous 

 tinge ; a thick, but not sharply defined, burnt-umber line from beyond one- 

 fourth costa to beyond one-third hindmargin, strongl}' outbent in middle ; an 

 elongate naples-yellow cell-mark, thickening at its posterior end ; a dark costal 

 spot just beyond, indicating the commencement of a very weak, dentate line ; 

 a dentate yellow subterminal line, commencing at about five-sevenths costa 

 (here accompanied proximally by a slight dark spot), very oblique outward to 

 R', slightly so to R', thence rather close to termen ; a strong dark dot on fold 

 proximally to the subterminal line ; fringe yellow, with a strong dark dot oppo- 

 site M'. Hindwing with termen faintly waved, very slightly concave between 



the radials ; vinaceous, mixed with umber in proximal half (especially at base), 

 with yellow distally to the subterminal hne ; a large, complex naples-yellow 

 patch in middle, namely an 8-shaped mark just outside the cell confluent in its 

 posterior half with a large patch in and just behind the distal half of the cell 

 a.nd proximally projecting a little into the anterior half thereof ; on this patch 

 stand in places some minute dark irrorations. particularly in the anterior half 

 of the 8-shapcd mark ; subterminal yellow line more nearly parallel with termen 

 (at nearly 1 mm. distant), rather deeply inbent between the radials. 



Forewing beneath somewhat vinaceous, at costa rodder, at base and hind- 

 margin pale, cell-mark eream-colour ; distal border for 1 or 2 mm. (most broadly 

 at apex, most narrowly in middle) cream-colour, from R' to hindmargin separated 

 from ground-colour by a smoky band ; a spot on fringe as above. Hindwing 

 beneath mostly cream-colour, a complete smoky band continuing that of fore- 

 wing. 



La Oroya, Rio Inambari, Carabaya. S.H Peru, 3,100 ft., November — 

 December 1905, wet season (G. R. Ockenden). Type in coll. Tring Museum. 

 Also from Rio Huacamayo, Carabaya, 3,100 ft.. June 1904, dry season. 



29. Tricentra citrinaria grisescens subsp. nov. 



Both wings with the dark parts of an almost uniform grey, with a slight 

 purplish tinge, the hindwing entirely without the rufous shades of c. citrinaria 

 Warr. (Nov. Zool. xiv. 222). The yellow submarginal band on both wings is 

 broad and pale, sharply defined, though on the hindwing the grey ground-colour 

 is shghtly mixed with yellow between the middle and this band.
