One i from La Murccd, Chauchamayo, Fcrii. 



Ilinilinargiii of both wings uniformly ciirveil, not augulated ; except iu this 

 respect, not tlifferiiig from typical Mixopsis, in which it may be left for the present. 



239. Mixopsis pallidaria sp. nov. 



Forewings : pale flesh-colonr, with some sparse black dusting ; first line fine, 

 black-brown, from one-fonrth of costa to beyond one-third of inner margin, forming 

 an acute angle ontwards iu cell, and a blunter one on submcdian fold ; closely 

 preceded by an olive-green line, dentate inwards on the median and submedian 

 veins, the included sjiace lustrous, white at the costa ; outer line similarly consti- 

 tuted, from costa shortly before apex to two-thirds of inner margin, but the dark 

 line followed by the green one, which is strongly dentate ontwards on all the veins, 

 most prominently on veins 7, 0, and 4, incurved from 7 to 4, closely approximated, 

 from vein o to inner margin, to a slightly sinuous dark brown oblinue line which 

 runs from three-fourths of costa to beyond middle of inner margin ; the space 

 between these hues deeper flesh-colour ; the green outer shade of the outer line is 

 followed by a diffuse pearly white tint ; marginal area deep flesh-colonr, above the 

 angle along the hindmavgiu dull green ; fringe flesh-colour, with darker mottlings 

 beyond veins above middle ; cell-spot distinct, round, black. 



Ilimlwings : satiny white, slightly tinged with flesh-colonr along hindmargin 

 and with a few scattered black scales along inner margin ; cell-spot black ; traces 

 of two black lines on inner margin at two-thirds, neither reaching midwing ; 

 fringe from apex to vein 4 white, with dark marks beyond veins, below vein 4 

 flesh-coloured. 



Underside satiny white, speckled with black ; the outer line on both wings 

 black, marked by vein-spots, which iu the forewings are connected ; forewings 

 slightly washed with brown, and with a dark brown blotch on costa before second 

 line, which becomes blackish beyond cell ; cell-spots large, black and distinct ; 

 fringe of forewings flesh-coloured, with slight mottling iu ujjper half ; of hindwings 

 wbite with blackish mottling throughout. Head and thorax pale flesh-colour ; 

 abdomen whiter. 



Expanse of wings : 44 mm. 



One 6 from 11. Tanampaya, Bolivia, 1894 (Garlepp). 



240. Nematocampa decolorata sp. nov. 



Forewings : pinkish cre.am-colonr, speckled with jiiukish brown ; the lines 

 brown ; first at one-third, bent on the subcostal vein, then straight ; second from 

 beyond two-thirds of costa to two-thirds of inner margin, slightly curved outwards, 

 and dentate inwards on the veins, preceded closely by a more curved and finer 

 median line, which joins it at inner margin ; discal mark long, crescent-sliapud ; 

 marginal area filled up with pale pinkish brown, except an irregular oval space 

 before apex, wliich remains of the pale ground-colour and is traversed by the darker 

 veins ; marginal line darker ; fringe brown. 



Ilimlwingx : with the costal area pale ; the marginal third pale pinkish brown, 

 to the inner edge of which a fine curved postmedian line is contiguous ; cell-mark 

 as on forewings. 



Underside very similar. Head, thorax, and abdomen like wings. 



Expanse of wings ; 28 mm.
