The underside is pale l)rown with the markings olive-brown ; the inner marginal 

 half of hindwing broadly yellowish. In the ? the reddish fnlvons ground colour 

 is almost hidden by dark fuscous suffusion in both winjjfs. 



The s]iecies varies in point of size : 2 ? ? from Ecu:idor measure 3'.' mm. 

 in expanse, whereas of four examples from Venezuela one, a (?, is only 28 mm. and 

 the three ? ? 20 mm. 



2-"). Dysodia innubila spec. nov. 



Differs from D. spcculij'era !Sep}) in being deeper, more uniformly copper 

 red ; the reticulations therefore are less prominent ; the lower half of the post- 

 median funnel-shaped band of forewin? is narrower, and the apical area beyond 

 the obliipie submarginal streak broader and darker; the red area between these two 

 runs up to the costal margin, whereas in speculifera the costo-apical area is clouded 

 as far as vein 6. In the hindwing the large h3'aline blotch is not only redneed 

 in size, bnt separated into two small but unequal spots.

2(). Dysodia spissicornis spec. nov. 



Forewing : dull reddish fulvous, more or less suffused with olive-fuscous, most 

 densely along costa and inner margin ; the reticulations and bands fuscous ; basal 

 and antemedian bands narrow, the jjostmedian broader, projecting outwards above 

 middle, and darkened on submedian interval ; costa with four pale marks, one 

 before, tlie others beyond the middle ; fringe brownish, ochreons in the two 

 crenulations above anal angle, and slightly beyond cell. 



lliiulwirxj : with numerous darker reticulations, but without distinct lines; 

 inner margin more fulvous, less suffused with olive ; cell-spot double, consisting 

 of a small white dot at upper end of discocellular and a slender curved mark at 

 its lower end. 



Underside j)aler, brown with a [link tinge, the markings olive-fuscous ; these 

 in the forewing are a narrow antemedian and broad postmediau band, the latter 

 interrupted in the middle, and an apical jiatch ; inner margin of hindwing 

 yellowish. 



Head, thorax, abdomen beneath, and legs olive-brown ; metatliorax and tips 

 of patagia mixed with fulvous ; dorsum with a [linky grey sheen, and laterally on 

 anal segments reddish ; third segment whitish with a black belt ; antennae fulvous 

 brown, with strong fascicles of cilia, which will at once distinguish the species 

 in the S.

27. Dysodia thyridina Feld. 

 This also is an entirely different sjiecies from xperuliffrn Sepp. The ground 

 colonr is ochreous suffused with brownish fulvous, not orange-red ; the dark costal 

 suffusion in both wings ampler ; the reticulation more minute, and assuming the 

 form of round pale spots between the veins ; the cell-mark of tiie hindwing is 

 shaped as in octilataiia Clem., the two spots being contiguous in the ? , and
