Expanse of wings : c? 35—40 mm. ; ? 48 mm. 



2 c?c? from La Union, 11. Hiiacamayo, Carabaya, Pern, 2000 ft., December 

 1004, wet season (Ockenden), type ; 3 cJcJ, 2 ? ? from Fonte Boa, Upper Amazons, 

 Angnst lOoO (Klages). 



Differs from the other species of the genns in the cliaractcr of the onter 

 line ; otherwise snperficially resembling T. hnsipl<i(ia Wlk. and janeiia Schans, 

 bnt mnch larger. 



The ? ? from Fonte Boa are of a much paler yellower green than the 3 3, 

 the yellow tint not being due to fading, as cJ c? from Fonte Boa taken at the 

 same time agree with those from La Union in colour. 



50. Tachyphyle fuscicosta spec. nov. 



Foiriciiig : dull greyish green, the costa strongly and irregularly marked 

 with fuscous, with two slight projections, one before middle above the black 

 cell-spot, which it reaches, the other at two-thirds, from which a very obscure 

 lunulate-dentate darker green line runs to two-thirds of inner margin ; a faint 

 inner line is also visible at one-third, shortly before the cell-spot; both lines 

 are more visible at the inner margin ; fringe concolorous. 



Ilindicing : with a small dark cell-spot only. 



Underside pale green, w^ith black cell-s])ots, and the costa of forewino- 

 fuscous at ajie.x. 



Head, thorax, and abdomen dull green ; verte.x wliito. 



Expanse of wings : 18 mm. 



1 S from Fonte Boa, Upper Amazons, September 1900 (Klages). 



Subfamily HYDRIOMENINAE. 

 57. Anapalta acerbata Feld., ab. perscripta nov. and variegata nov. 



The form for wliich I propose the name perscripta differs from typical 

 acerbata Feld. in having the forewing suffused with grey, with all the lines 

 well ex])ressed across the wing ; the dark basal patch is generally jiresent, but 

 the two dark costal spots at the origin of the bands limitiug the central fiiscia 

 and the apical blotch are variable ; the basal jjatch is edged with white, and 

 the space between it and the central fascia is sometimes wholly whitish ; hind- 

 wing dull whitish grey, with the marginal area darker grey, and the postmedian 

 and submarginal lines more or less evident. 



1 6 from Huancabamba, Cerro de Pasco, Peru, C40U ft. (Boettger), type ; 

 1 ? from La Oroya, R. Inambari, Pern, 31(Mi ft., September 1904, dry season 

 (Ockenden). 



This form seems widely spread in Pern. 



The aberration variegata seems less common : in it the ground-colour is 

 chalk-white, and the basal patch, costal blotches, and apical shade brown instead 

 of black, and well marked ; the lines forming the bands of central fascia are 

 strongly marked, the inner band being filled in with brown throughout ; the 

 bands are joined in cell and submedian fold by irregular blackish horizontal 

 smears, the latter extending sometimes to inner margin ; hindwing white, with 

 the outer lines and shade dark grey.
