resembles in the sexual diiferences in coloration. It differs at once 

 from all three by the absence of the Terias-like black margins to 

 the primaries. 



Tt seems almost certain that at least a single female specimen of 

 Helicopis Lindeni is contained in the Entomological cabinets of 

 Vienna; for in a paper entitled, "Specimen fimnae lepidopterolo- 

 gicae riparnm fluminis Negro superioris in Brasilia septentrionali," 

 C. and R. Felder refer to a doubtful variety of Helicopis Cupido in 

 terms' which sufficiently apply to Mr. Linden's butterfly. Whether 

 our surmise in this respect is correct or not, there can be little 

 doubt of the validity of Helicopis Lindeni, both sexes of which are 

 illustrated in the present article.

$ $ . — Above the primaries are pale ochery white, without bor- 

 ders; in the male suffused with yellow at base and with a narrow 

 terminal ocher shade Avidening to the apices. The hind Avings are 

 stained with ocherous, more deeply so in the male, with whitish 

 tips to the " tails," and a narrow terminal gilding Avithin the pale 

 emarginations ; the fringing is deep ocherous. There are depres- 

 sions on the tegument answering to the metal spots beneath. On 

 the under-surface the fore Avings are Avithout borders, pale ocher 

 Avhite in the female, and in the male Avitli yellow ocher base shading 

 into black someAvhat as in H. Oupido, but less distinctly, the black 

 color being undefined and not so medially produced about veins 3 

 and 4 ; the fringes are ocherous, as is the costal region of the $ 

 primary. The terminal margin shoAvs an ocherous linear shade, 

 including gilded scales. The hind Avings beneath are pale ocherous, 

 darker in the male, and both sexes shoAV the usual three series of 

 metallic spots. These are, hoAvever, comparatively larger and purely 

 argent in the new species, the costal spots ringed with deep ocher- 

 ous, and not darkly annulate as in H. Cupido. The body parts are 

 unusually pallid, and the antennae annulate as in the other species. 

 The neAV species is larger than H. Cupido, expanding the male 46, 

 the female 48 m. m.
