2 c?c?, 1 ? from 8auto Domingo, C!arabaya, S.E. Peru, 6000 ft., November 

 1 902, wet season (Ockenden). 



Very mnch like //. ;j«f/m^f Guen., but smaller, withont the yellow markings,

The examination of the c? of this species proves it to be a Ili/polepis. It 

 differs in coloration from the ?, being olive-tinged thronghont. The antcnnal 

 structure, moreover, is abnormal ; the shaft is thickened, rasped above, and beariuu- 

 short curved clavate teeth below. 



The only S hitherto seen was taken at the same place as the ?, Santo 

 Domingo, S.E. Pern, and at the same time of year (Ockenden). 



Isodiscodes gen. nov. 



Differs from all other Ili/driomeninae in having the discocelhilar of forewing 

 exactly like that of the hindwing, biaugulate, the upper and lower ends vertical, 

 the middle oblique, the lower radial from the lower outward angulation ; the 

 upper radial is stalked with 7, 8, 9 ; the areole donble. Antennae lamellate, 

 without pubescence ; palpi short, straight, rough-haired below. 



Type : Isodiscodes •polycyma spec. nov. 



64. Isodiscodes polycyma spec. nov. 



Forewing : cream-colour ; the lines and shades dark olive-fuscous ; the edge of 

 the basal patch, the narrow central fascia, the space before submarginal line, 

 and the marginal area are all olive-fuscous, formed by the coalescence of two 

 or three dark lines leaving irregular pale spots; these are separated by three pale 

 bands, antemedian, postmedian, and submarginal, consisting each of two lunulate 

 lines separated by a similar line of olive-fuscous; the basal patch itself is also 

 traversed by a donble pale line; cell-spot olive- fuscous ; a distinct marginal Hue; 

 fringe mottled cream-colour and fuscous. 



Hindwing : cream-colour, with grey marginal line and mottlings in fringe 

 beyond veins ; a small grey cell-spot on upper half of discocelhilar ; a grey spot at 

 anal angle. 



Underside the same, the markings of forewing blurred. 



Palpi dark fuscous, the tips pale ; face cream-colour, with a large fuscous 

 central sjwt; vertex fuscous ; antennae fuscous, the basal joint cream-colour ; collar 

 cream-colour ; thorax olive-fuscous intermixed with grey ; abdomen cream-colour, 

 the dorsum tinged with grey ; a dark ring before anal segment ; legs mottled,
