liliu-kish ; marginal area somewhat darker, except at ajiex, containing faint trai'cs 

 (if a snbmarginal line. 



Underside jialer gre}', with sparser and largei' dark nidttliiigs; cell-s]iots black, 

 distinct; outer line blackish, interrnpted. followed by a black submarginal clond, 

 which does not reach the costa. Hindwiug with the submarginal cloud broader and 

 externally dentate, preceded by a curved dentate line, marked by black vein-spots ; 

 !i slight dark line between this and the cell-spot. 



Head, thorax, and abdomen grey ; tlie fillet slightly paler. 



Expanse of wings : 70 mm. 



1 S from Paramba, Ecuador, November — December 1898, ff/pr ; 166 from 

 San Ernesto, Bolivia, inoo m., August — September 19(10 (Simons). 



Of these seven examples three dift'er from the type form, with which the other 

 four agree, in having the outer half of wing before the dark obliiiue line suffused 

 with olive-green, darkening to the line, which is more or less lost in the suffusion. 

 In one instance the whole wing to base is thus suffused, the line is narrower, 

 suberenulate, and edged with jiale, and the basal line and median shade are both 

 strongly develoi)ed. This aberration, which may be named perj'usa, superficially 

 much resembles M. t/ist/c/iata Gueu., but on closer comparison they will be found 

 distinct. 



It is, however, quite possible that the species here described is identical with 

 M. avomata Druce {0.ri/(/i(i), Biol. Centr. Am., Leji. Ilct. ii. j). 27. t. XLILI. 

 fig. 11, described from a ? . I have quite lately been able to examine a ? exactly 

 like that figured, and, though the two sexes are very different in outward ajqiear- 

 ance, the disposition of the markings strongly suggests their identity, which further 

 experience must be left to determine.

Forciriiui : yellow oohreons, with an olive sufl'usion, which is much more 

 pronounced in the S than in the ?, and thickly S2)eckled with coarse olive atoms 

 which are more conspicuous in the ¥ ; basal area darker, — more densely sjieckled, — 

 than the rest of wing, bounded by an (dive-grey line at one-third, outcurved above 

 and below the median vein ; a small black cell-spot, followed by a median shade, 

 often inconspicuous, but well njark(_'d and distinct in some of the paler, yellower, 

 exanijiles of the ?; outer line oblique from beyond middle of inner margin towards 

 apex, before which it is acutely angled on vein 7, and retracted to three-fourths of 

 costa; in the cJ this line is usually thick, dark brown, in the ? finer, olive-grey, 

 outwardly edged with a pale line of ground colour, generally followed by a darker 

 grey shade, cloudy in the S, and formed of speckles in the ? ; a dark grey, 

 irregularly zigzag, cloudy submarginal line, jilainer in the ? ; the apex of the wing 

 darkened with speckling ; fringe darker. 



IlixdiruHj : with a central dark line, bent on vein and always thicker above 

 the bend, often, but not always, followed on costa by a blackish blotch ; submarginal 

 line as in forewing. 



Underside ochreous tinged with ochraceous, coarsely speckled with grey, more 

 thickly in the ¥ ; all the lines marked, and in addition a postmediau line, closely 

 approximated to outer line on the inner margin of forewing, diverging from it
