•58. Heterephyra neximargo sp. nov. 



Foreirings: straw-colour, diisfed with t'erruL;'iiiou.s orange, but the grouud-colour, 

 except along hindmargin and base of inner margin, more or less den.sely snflused 

 with purplish grey ; first line obscure, at one-fifth, irregularly curved, the jialo luisal 

 area suffused with grey along costal half ; median line thick and distinct from 

 middle of costa, bent outwards to vein G, then vertically concave to vein 4, then 

 slightly incurved to three-fifths of inner margin, obscurely lunulate dentate ; outer 

 line distinctly dentate lunulate, the lunules filled in with the i)alc ground-colour, 

 miming mainly jiarallel to median line, from two-thirds of costa to four-fifths of 

 inner margin, projecting ioutwards between veins 3 and 4, and there followed by 

 a whitish oclireons spot in place of the gronad-colour ; marginal area beyond 

 ])urplisli grey, excejit two irregularly semicircular patches, one above, the other 

 below the middle, traversed horizontally liy the darker veins and transversely by 

 a zigzag line close before the margin, the outer teeth of which are joined by short 

 iuterneural streaks to the dark marginal line ; fringe straw-colour, chequered with 

 purplish grey beyond the vein-ends ; cell-mark linear, varied with orange scales 

 and containing a black dot at each end. 



Hindicimjs : similar, but the pale marginal patches and outer line lost in the 

 darker suffusion and only traceable near anal angle ; fringe wholly dark purplish 

 grey, the inner line represented by a thick straight grey shade. 



Underside duller straw-colour, without the orange dusting ; all the markings 

 distinct, purplish grey, the dark suffusion, except towards hindmargin, being very 

 much reduced. Face and palpi reddish grey, paler below ; head and patagia straw- 

 colour, dusted with orange ferruginous ; thorax and abdomen purplish grey ; anal 

 tufts yellowish ochreous. 



Expanse of wings : 32 mm. 



One 6 from Perene River, Peru, March 1896 (Simons). 



All the anal tufts very largely developed ; the penultimate segment of abdomen 

 beneath with large curling lateral tufts, and the middle segments with shorter tufts. 

 In both wings the hindmargin is slightly bent at vein 4. The species is closely 

 related to Heterephyra lunifera Warr., from Colomliia, described from a S onlj', 

 and also to H. commaculata Warr. {Dysejihi/ra), from Rio Demerara. All three 

 species agree in having the discal marks linear, with black dots at each end. It is 

 not impossible that they represent local forms of one sisecies, in which the dark 

 suffusion is liable to considerable variation both in disposition and intensity. 



Subfamily ASTHENINAE. 

 59. Cambogia cervina sp. nov. 



Foreiii/iffs : pinkish fawn-colour, tlie usual waved cross-lines brownish grey 

 and somewhat indistinct ; the outer edge of central ftiscia and a blotch on hind- 

 margin between veins 3 and 4 being darker and more conspicuous ; marginal spots 

 dark between the veins, not at their ends : fringe pale fawn-colour ; cell-spot small, 

 l)lackish. 



llim/iviiigts : similar, tlie central fascia narrower. 



Underside paler. Head, thorax and abdomen concolorous, the fillet not white. 



P]xpanse of wings : 26 mm. 



One ? from Lifa, Ecuador, 3000 ft. (Flcmming). 



Distinguished at once by the absence of all yellow tints.
