Expanse of wings : 34 mm. 



Two 66, one ? from Rosario, Argentina, December 1898 (Stuart) (type), 

 and three ? ? from Castro, Parana, November 1897 (E. D. Jones). 



Distingnished from lY. favaria Gnen. by the smaller size, darker tint, and 

 absence of cell-spots ; the lines also are thicker, and differently disposed. 



Subfamily ASCOTINAE. 

 102. Alois junctilinea sp. nov. 



Forewings : whitish, dusted with dark grey; the lines blackish fuscous, 

 distinct ; first from one-third of costa obliquely curved inwards to one-fifth of 

 inner margin, preceded liy a diffuse smoky fnscons shade, which edges the fovea ; 

 both marked with lilack dashes on the veins ; outer line from two-thirds of costa 

 to three-fifths of inner margin, slightly outcurved round cell, then oblique inwards, 

 marked with black on veins, followed by a parallel smoky shade, similarly marked ; 

 cell-spot black, linear, crossed by a difi"ase smoky fuscous median shade which 

 is contiguous to the outer line across the submedian interspace and is marked 

 with linear black dashes across the veins ; subraarginal line denticulate, pale, 

 plainest from costa to vein 5, where it is preceded and followed liy darker clouds ; 

 marginal spots black ; fringe whitish. 



Hindwings : with the markings less e.xpressed ; a line close to base, and traces 

 of an antemedian shade ; cell- spot and outer lines as in forewings ; the veins slightly 

 marked with black scales. 



Underside whitish, iridescent ; costa of forewings ochreous, speckled and 

 blotched with black ; forewings with blackish apical blotch leaving apes itself 

 pale ; both wings with cell-spots. Head, thorax, and abdomen whitish, much 

 peppered with grey, the face and palpi darker. 



Expanse of wings : 30 mm. 



One c? from Tucuman (Gerard). 



Resembles A. perstrigata Warr. {Tridopsis), bufsmaller and without the black

Foreicings : whitish, striated, and in parts suft'nsed, with olive-fuscous, and 

 peppered with black scales ; first line black, curved, from one-fifth of costa to

 line from two-thirds of costa to middle of inner margin, black, denticulate, pro- 

 jecting outwards at veins 5 and 6, then oblique and somewhat sinuons : submarginal 

 line whitish, irregularly crenulate ; space between it and outer line filled in with 

 suftused olive-fuscous, darker, in middle and above inner margin, and traversed by 

 an indistinct denticulate line ; marginal area olive-fuscous, except the apical area 

 and a blotch between veins 3 and 6, which remain white with a few sjieckles ; 

 black marginal spots between the veins, united by a fine crenulate line; fringe 

 olive-grey ; the central area is white with olive-fuscous speckles ; the median line 

 obscure, parallel to outer line, and at inner margin almost joining the first line, 

 traversing the dark difl'uso cell-spot. 



Hindwings : without first line, the antemedian distinct at inner margin only ;
