* Dioptis paracyma sp. nov. (sequ. form. ?). Differs from cyma in having tho white obUque 

 bands of the forewing not cut by dark veins, except that the stalli of R^ — M' and the space between 

 them is broadly darlcened across the postmedian band ; this band does not cross SC^^ ; orange sub- 

 costal spot generally much reduced. The hindwing appears slightly less produced apically. 

 Upper Surinam River, August 1892, type cj and another; interior of Surinam. September 1892 

 (C. W. Ellacombe), 1 ? ; Humayta, Rio Madeira, July — September 1900 (W. HofTmarms), 3 cfcj ; all 

 in coll. Tring Mus. 



t Dioptis proix sp. nov. (J $, 40-43 mm. Differs from cheledonis Druce in the forewing, as 

 follows. Subapical brownish suffusion obsolete ; hindmargin predominantly blackish, the orange 

 admixture being feeble ; anterior region broadly blackened, the pale streak between costal margin 

 and C being obsolete, that between C and SC weakened, the postcellular white spots before and 

 behind R^ entirely wanting, that before R^ narrowed, sometimes wanting ; outer white band ou 

 an average narrower; subtornal spot weaker. Rio Ucayali, Peruvian Amazons, 1912-1913, 3 (J(J, 

 1 ?, including the type, in coll. Joicey. S. Peru : Chaquimayo, 2,500 — 3,000 ft., June — July 1910 

 (H. and C. Watkins), in coll. Joicey ; Yahuarmayo in coll. Brit. Mus. 



Perhaps a local race of cheledonis or of uniguttata. 



X Dioptis ilerdina curvifascia subsp. nov. ^. 



Forewing with the proximal white markings more developed, a streak between fold and SIP 

 and a spot distally to base of M^ being conspicuous ; postmedian band always narrow (in ilerdina 

 ilerdina usually broader than in Bates' figure), posteriorly strongly curved. Huraayta, Rio Madeira. 

 July— September 1906 (W. Hoffmanns). 5 cJ<J in coll. Tring Mus.
