68. Perizoma fallax tsjiec. iiov. 



Forewing : chalk-white, rather glossy ; in the outer half tinged with pale 

 grey and brownish ; basal patch jinrplish I'nscons, crossed by three deeper lines, 

 the outer edge oblii[ue and irregular from oue-third of costa to two-fifths of inner 

 margin ; a dark blutch at middle of costa, sometimes double, from which a double 

 line runs obliiiuely outwards to vein H, where it is bluntly bent iiml turns obliijuely 

 inwiirds, lunulate-dentate, but often very obscure and marked witli diirk dots on 

 the veins ; the inner of the two arms runs to a small dark blotch at middle of 

 inner margin (which, in one case, is confluent witli basal blutch) ; the outer to 

 another blotch before anal angle; a whitish waved snbmarginal line, most distinct 

 on costa, where it is preceded by a large black blotch reaching to vein (i, and 

 followed by a smaller one to apex ; between veins 2 and 3 a bluish grey longitudinal 

 blotch reaches from middle line to hindmargin ; a black cell-mark within the curve 

 of the double line : marginal line interru]ited ; fringe white with rather large dark 

 spots in the basal half beyond the veins. 



Hituhi'infi : dull white, clouded with grey along hindmargin, and with a small 

 black blotch at anal angle ; a grey cell-spot and traces of outer lines. 



Underside of forewing dark grey, shining; ])aler beyond middle of costa. with 

 black cell-spot ; of hindwing white with basal half speckled with grey ; a black 

 cell-spot, and dotted curved outer line. 



Head, thorax, and aVidomeu blackish; anal segment of abdomen whitish; 

 abdomen below legs whitish. 



Expanse of wings : 18 mm. 



2 S S from Huancabamba, Cerro de Pasco, Peru, 64ii0 ft. (Bcittger). 



Evidently allied to F. basiplaya {Fsaliodes) Schaus from Mexico. 



In a J and ? from Santo Domingo, L'arabaya, S.E. Peru, which are probably 

 referable to this species, the dark middle cloud is much less developed. 



6U. Perizoma ochritiucta spec. uov. 



Forewing : dull grey with the markings darker, but very indistinct ; basal 

 area small, limited and crossed by grey lines ; paler band before central fascia 

 broad, also traversed by grey lines ; inner edge of central fascia from une-third of 

 costa to two-fifths of inner margin ; outer from quite two-thirds of costa to three- 

 fourths of inner margin, projecting at veins 6 and 4, and Strongly dentate-luuulate 

 throughout, the fascia crossed by darker lines ; area beyond it with the usnal lines 

 all very obscure; the cell and space beyond and the submedian interval are slightly 

 tinged with ochreons-yellow scales, a spot at end of cell being noticeable. Fringe 

 (worn) grey. 



IFuuhcimj : dull pale grey, without any distinct markings. 



Underside dull cinereous. 



Head, thorax, and abdomen all dark grey, the abdomen with paler rings. 



Exjianse of wings : 'Z'i mm. 



1 $ from Huatuxco, Vera Cruz. 



The antennae are thick, lamellate and faintly pubescent. 



A very dull and obscure-looking species, but ajiparently distinct; it bears some 

 resemblance to dark specimens of F. mmcosata \Varr., which is probably the ? of 

 F.Jasciolata, from Argentina, but the forewing is longer and narrower.
