llindicinqH : oolireons, witli iiulistiiict cross linos. 



Underside with the mavkings of forewings somewhat more visible. Face and 

 palpi reddish; thorax and abdomen ochreons. 



Expanse of wings : 16 mm. 



One $ from Cucnta, Venezuela. 



In shape of forewings, which are pointed, this spenies resembles Pt. .tiibrestifa. 

 The hindwings are irregnlarly oblong, the hindmargin bluntly ])rominent below the 

 median; they are without the tufts and folds of hair which occur in Pt. snliroitita 

 and percrinita, but instead the whole under surface is covered with fine erect down- 

 like hair, as in those of Brachyprota ((bnormipfinnis, from which the species 

 differs in the less exaggerated prolongation of the hindwings, and in their costal 

 vein being complete. 



96. Ptychopoda subvestita sp. nov. 



Forewings : ochreons, dusted with darker, esjiecially along the costa ; the lines 

 indistinct ; postraedian line running nearly straight across the wing to inner margin 

 before anal angle, indistinctly denticulate ; a small dark cell-spot, and traces of a pale 

 snbmarginal line between two darker shades ; marginal dots elongated, brownish; 

 fringe ochreons. 



Hindwings : with only traces of curved lines ; cell-spot absent ; marginal dots 

 as in forewings. 



Underside tinged with deeper ochreons, tlie lines mucli plainer; the postmedian 

 line denticulate; the snbmarginal shades disthict. Head and face brown-red; tliorax 

 and abdomen ochreons. 



Expanse of wings : 16 mm. 



One t? from Petropolis; one <?, one ?, from Santos. 



This insect is related to Pt, percrinita, from Sao Paulo, having the fringed tufts 

 of hair on the costa of hindwings beneath, as well as the wisjis of hair along the 

 discocellular and the veins ; but these are all exaggerated in the present species, the 

 hindwings of which have on the upper surface also a folded lappet at base of costa 

 reaching nearly to the middle of the wing, and the discocellular with raised scales ; 

 the hindwings themselves are much elongated and narrowed at base : the forewings 

 have a small tuft of hair in the middle of hindmargin ; the tuft of hair covering the 

 aborted hindlegs is black beneath, while in Pt. percrinita it is wholly ochreons ; 

 the antennae, instead of being simply pubescent, are snbserrate and clothed with 

 long cilia. 



In the hindwings veins 2 and 3 are stalked, the stalk being curved and 

 thickened. Snellen remarks a similar peculiarity in his chlorosata from Uhaque, 

 Tijd. V. Ent. XVII. p. 56; but though he had fourteen S S of his species, he makes 

 no mention of the tuft of hair on forewings, or of the jiecnliar ajipendages of tlie 

 hindwings, and so I presume the two species to be different. 



The ? has narrower more pointed forewings than the J : but. on the contrary, 

 the hindwings shorter, obovoid. the hindmargin protuberant towards aual ;uigle. 



!i7. Ptychopoda triangularis sp. nov. 



Forewings: dull grey, dusteil and marked with darker grey: the lines all 

 straight, very obliiiue, parallel to the oblique hindmargin: the antemedian generally 

 obscurely double, the outer arm being retracted to the costa before the dark cell-
