 318. Isochromodes rufigrisea. 



SliiliH-vii^jicrhi riiji'ijrisci Warr., A'«r. Zfm!. vii. p. "224 (I'.iOO). 



The species was described from a ? only ; the S jiroves to be somewhat 

 diftereiit, being iinitbriually dark brown, without the reddish and grey variations 

 of the S. In the ? the space between inner and median line is grey, and between 

 median and outer line reddish ; in the S both are brown, the outer rather darker ; 

 the outer brown line is more conspicuously edged with slightly lustrous grev ; 

 the marginal area is brown like the rest of the wings, the submarginal line 

 being indicated by darker grey-edged lunules preceding it, more or less incon- 

 sjjicuous, but the two on veins 2 and 3 always black, followed by an outer 

 blackish blotch, and all surrounded by grey scales. These are present on the 

 liindwing also. Underside as in the ?. The antennae are like those of /. aiixilians, 

 the angles of the joints being produced and bearing short tufts of cilia.

31 '.I. Isochromodes terminata spec. nov. 



FovciriiKj : dark brown ; both in colour and markings very much resembling 

 the i S oi I. rufigrisea ; but in tliis case both sexes are alike; the two lines 

 darker than the ground colour, thick, and marked with fine white dashes on 

 the veins ; the first slightly curved from one-fourth of costa to one-third of 

 inner margin ; the outer from four-fifths of costa to two-thirds of inner margin, 

 bent outwards between veins 5 and 2 ; cell-spot black ; in the ? there is a 

 slight patch of dark grey scales between veins 3 and 4 beyond outer line ; in 

 the i there are two black wedge-shaped marks on veins 2 and 3, as in rufgrisea 

 S ; fringe brown, with dark spots beyond veins ; in the ? the base of fringes 

 is distinctly whitish ; the outer line is whitish on inner margin. 



Hind icing : similar, without basal line. 



Underside cream-colour, slightly dark-speckled ; the marginal borders dark 

 fuscous throughout ; fringe brown, with pale base and distinct dark spots beyond 

 the veins. 



Head, thorax, and abdomen brown. 



Expanse of wings : 28 mm. 



1 cJ, 1 ? , from Santo Domingo, Carabaya^ S.E. Peru, dOOO ft., November lOOl, 

 wet season (Ockenden). 



The c? antennae are subserrate, hardly pubescent, without ciliations or fascicles. 



3211. Isochromodes vestigiata spec. nov. 



Forewing : sandy ochreous, thickly but finely dusted with fuscous ; the lines 

 very much as in innotata Warr. and its allies ; the inner line vertical and slightly 

 waved at one-third ; the outer from five-sixths of costa to two-thirds of inner 

 margin, angled outwards on vein 4, slender and brown, not marked by black 

 vein-dots, but followed by a grey shade ; the median line waved and ajiproaching 

 outer line above inner margin, passing beyond the black cell-spot ; submarginal 

 marked by dark spots or blotches on veins ; marginal dots small ; fringe 

 concolorous. 



Hindwing : with the outer line slightly angled outwards at vein 4, meeting
