9. Steroma mnbracina, n. sp. B.M. 



Form of 8. pronophila. Wings above olivaceous brown ; 

 primaries with the apical third slightly paler, the fringe 

 alternately black and dull tawny : below nearly as above ; 

 secondaries with apical area cinereous brown, interrupted by a 

 submarginal, interrupted, waved, dark brown line. 



Expanse of wings 1 inch 7 lines. 



Two examples. 



Genus 5. Pedaliodes, Butler. 



10. Pedaliodes Ereiba, local form peruviana. B.M. 



Pronophila Ereiba, Felder, Reise der Fregatte ' Novara,' iii. p. 469. 

 n. 800 (1867). 



A somewhat modified form of this species occurs in the col- 

 lection. It differs from the typical race in its deeper coloration 

 above and below, the obsolete character of the bands below, 

 and the more ferruginous tint of the internal area ; the white 

 point is also rather further from the margin. The type of 

 P. Ereiba was from Bogota. 



11. Pedaliodes ferratilisj n. sp. B.M. 



Wings above pitchy : below, primaries paler, externally 

 hatched with blackish ; fringe greyish, varied with dirty 

 white ; secondaries pitchy, hatched with blackish ; internal 

 area, excepting at base, ferruginous ; a quadrate patch of the 

 same colour, irrorated with fulvous, from first median branch 

 to anal angle, bounded internally by an irregular central 

 blackish line ; outer margin broadly red-brown, bounded in- 

 ternally by a waved submarginal black line ; a white point 

 on first median interspace. 



Expanse of wings 2 inches 5 lines. 



Allied to P. Pheretias of Hewitson. 



12. Pedaliodes niveonota, n. sp. B.M. 



Wings above pitchy : primaries below ferruginous ; the 

 costa brown, hatched with blackish, and clothed towards the 

 base with yellowish hair-scales ; a quadrate brownish spot at 

 end of cell, beyond which, upon costa, is a cuneiform patch of 

 pale yellowish scales ; outer margin broadly brown, the inter- 

 nervular folds black ; a squamose submarginal grey band, en- 

 closing three white points and sinuated externally, near apex ;
