waved fnlvous median line, hent outwards above, and below the median approxi- 

 mated to outer line ; large blaek subterminal t^pots on veins I, 2, 3, and 5; a 

 black streak from the angle of outer line above vein 3, and another below vein 3, 

 the two joining an angled black mark at the margin across vein 3; small black 

 marginal dots, that on vein 3 larger ; fringe ochreons. 



Ilindwinii : without first line ; a curved blotch of black scales from inner 

 margin between median and submarginal lines ending in the angled mark at 

 vein 3. 



Underside paler, thickly black-speckled, witli an irregular ditfiise blackish 

 snbterminal shade on both wings. 



Head, thorax, and abdomen ochreons ; liice whitish ; antennae, tips of shoulders, 

 a large blotch on metathorax, and the anal segments of dorsum black. 



Of the two ? ? neither agrees exactly with the $ ; one has all the black 

 spots enlarged, but the two horizontal black streaks to margin of forewing and 

 the curved black blotch on hindwing are both absent, and the dorsum is simply 

 black-spotted on each segment ; the subterminal shade beneath is darker and 

 larger. The other ?, ab. dissipata, lias no spots whatever; the two arms of 

 the outer line coalesce to form a thick black Innulate-edged shade, throwing out 

 two strong Ijlack projections above and below vein 3 ; and the black curved 

 mark on hindwing is strongly marked ; in both wings there is a black marginal 

 line from below median vein to anal angle. Underneath the submarginal shade 

 is slight on forewing and absent on hindwing ; the cell-spots are entirely absent 

 on both sides. 



Expanse of wings : 35 mm. 



1 c?, 2 ? ?,from Santo Domingo, Carabaya, S.E. Peru, 6000 ft., November and 

 December 1901, wet season (Ockenden). 



The c? antennae are subserrate and ciliated. Both this and the succeeding 

 species must be allied to Isochromodes he.rmeja Dogn. {Sabulodes). 



311. Isochromodes auxilians spec. nov. and ab. denotata nov. 



(?. Foreiciuii : jiale wood-colour, thickly freckled with dark atoms; the costa 

 speckled and striated with grey ; the lines nearly as in /. atristicta, but the inner 

 line at one-third is thick, nearly vertical, bent only below costa ; dark grey in 

 colour and hardly marked with darker on the veins ; the outer line is neater and 

 marked with slighter black spots, and above vein 7 is retracted to costa instead 

 of running into apex ; the subapical spot visible belongs apparently to the 

 submarginal series in this species ; the black marks above and below vein 3 are 

 present but variable in extent and intensity ; cell-spot and marginal spots black, 

 and of ordinary size. 



Hindwiny : with the curved black blotch large in the tyjie form, absent in 

 the aberration denotata. 



Underside with a very slight submarginal grey shade in forewing, but the 

 outer line distinct. 



The single ? , which belongs to the aberr. denotata, differs in having the 

 median line blackish instead of fulvous ; the outer line concisely black, edged with 

 grey, forming two simple curves from inner margin to vein 4 and again to vein 7, 

 where it is plainly retracted to costa ; the dark scales at vein 3 of forewing and 

 anal angle of hindwing are all but absent ; underneath, on the contrary, the outer 

 line and submarginal shade are blackish and strongly marked.
