It seems ahno.st certain that at least a single fcinule specimen of 

 Ilelicopis Tjituleni is contained in the Entomological cabinets of 

 Vienna; ft)!' in a paper entitled, "Specimen faunae lepidopterolo- 

 gicac rii)arum fluminis Negro superioris in Brasilia 8e])tentrionali," 

 C. and K. Felder refer to a doubtful variety of Ilelicopis Cupido in 

 terms' Avhich sufTiciently apply to Mr. Linden's butterfly. Whether 

 our surmise in this respect is correct or not, there can ]»■ little 

 doubt of the validity of Ilelicopis Lindcni, both sexes of Avbich are 

 illustrated in the ])resent article. 



Helicopis Liiuleni Orute. Plate 2, figs. 1, 2 <5 , 3, 4 $ . 

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

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

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

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

 tips to the "tails," and a narrow terminal gilding within 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 wings are without borders, pale ocher 

 white in the female, and in the male with yellow ocher base shading 

 into black somewhat as in 11. 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 sIioavs 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, however, 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 ncAv species is larger than H. Cupido, expanding the male 40, 

 the female 48 m. m.
