very rare. Also in Eio de Janeiro the species is no longer very common, but it apparently occurs in larger numbers 

 in Espiritu Santo. Examples from there are by far the largest, somewhat lighter blue, and both sexes have 

 the apical spot on the forewmg paler yelloAV and more extended than in my Santa Catharina specimens. Moreover 

 the basal area on the underside of the hindAviiig is appreciably lighter and in the 5 the distal border of the 

 brown median area is much lighter, one might almost say pure white. According to Buembister heltrao also 

 occurs in Argentina, but I do not know anj' Argentine examples in nature.

C. teucer, one of the most inconspicuous species, is distributed over the entire region in which the Ca- 

 ligos occur with the exception only of Central America and Mexico, teucer is less susceptible to climatic influen- 

 ces than other species of the genus and consequently only splits up into a small number of not very sharply 

 differentiated local forms. — In insulanus Stich. the costal area of the forewing in the ^ is of an indefinite insulanus. 

 light grey, not or scarcely brownish, the yellowish white transverse band distally to the cell very narrow and dull, 

 the triangular hindmarginal area grej'-blue fully to its anterior limit, also the cell for about half its breadth 

 with a vague grey-blue tinge. The distal marginal area blackish, the undulate lines near the margin only quite 

 indistinctly showing thi'ough and only slight traces of a band present between them. Basal area of the hind- 

 wing grey -blue, in an oblique light with violet-blue reflection in its distal parrt, extending nearly to the end of 

 the cell, distal half of the wing blackish Avith quite fine whitish border. The $ larger, the band of the forewing 

 somewhat broader, anteriorly more or less dusted with dark, from the posterior angle of the cell onwards 

 purer whitish yellow, posteriorly again blurred. The blue dusting of the hindmarginal area is continued anteriorly 

 in the cell, only leaving a narrow costal stripe. The band near the distal margin of a very fine and distinct 

 whitish yellow, the proximal boimdary strongly curved and very sharp, the distal less strong, but distinctly 

 defined by a dark-dusted stripe. Hmdwing with the basal area widened, distally likewise with a beautiful iri- 

 descence. This extends to bej'ond the cell and to the hindmarginal vein. Distal margin of the hindwing somewhat 

 more strongly dusted with whitish than in the ^; abdomen with bluish gloss. Trinidad. — suzanna Deyr. suzanna. 

 is a dark subspecies ; forewing from the hindmargin nearly to the costal margin and the narrow whitish band 

 tinged with blue. Marginal area almost black, the submarginal undulate line not conspicuous, the margin itself 

 strongly undulate, cj^uite finely edged with whitish. Hindwing velvety black, distal margin finely whitish. Basal 

 area greenish to near the end of the cell or even somewhat further and nearly to the anal angle, at its extremity 

 with clear blue reflections. Under surface strongly and copiously marbled with brown and black-brown. In 

 the posterior median cellule of the forewing is placed a small, rather distinct eye-spot, a larger one near the 

 apex. The ring round the posterior eye-spot of the hindwing is very light yellow, nearly white, laterally and poste- 

 riorly more yellow, at the outer margin changing into rust-yellow. The brown band-like colouring between 

 the anterior and posterior eye-spots only persists as a narrow, sometimes quite indistinct stripe running through 

 the cell, the smaller oval patch distally to the middle discocellular more or less distinct. The $ has broad- 

 er -wings, otherwise c^uite similar. In the forewing the light band running between the marginal lines near 

 the distal margin and the black spots at the costal margin near the apex more distinctly expressed. The blue 

 reflection on the hindwing extended somewhat beyond the end of the cell. On the under surface the hindmar- 

 ginal area of the forewmg to the submedian striated, like the rest of the wing, the small posterior eye-spot 

 in the distal area absent. In the median area of the hindwing the brown band-like shading better 

 developed, in the cell a distinct elongate light patch. In general the striation and marbling on the 

 entire surface of both wings somewhat coarser and darker. In transitions to the typical subspecies, not lo- 

 cally constant. Colombia. ■ — ■ phorkys subsp. nov. differs from phoroneus Fruhst. in the narrower, phorkys. 

 washed-out yellowish grey longitudinal band of the forewing, which is broken up into separate spots and 

 is also distinguished at once irom suzanna Deyr . by the isolated patches. Under surface lighter than phoro-

 the costal area of the forewing is broadly grey-brown, cell also grey -brown except a narrow stripe in the posterior 

 half. The brown area is approximately spindle-shaped with the points placed at the base of the wing and at 

 the costa before the fork of the 4th and 5th subcostal veins. The transverse band beyond the cell begins 3 — 4 mm. 

 in width, is distinct to the angle of the cell, then only sharply defined distally, and terminates at the posterior 

 median vein. In the middle and posterior median cellules it forms two shallow curves. The light grey median 

 area is widened posteriorly and forms a long acute-angled triangle to the hindmargin. Posteriorly the colour 

 becomes a trifle darker, particularly at the base of the wing, and is slightly tinged with bluish. The distal area, 

 for an average breadth of 18 — 19 mm., is dark to pale smoke-brown, fringes and a quite fine marginal stripe 

 dirty white, the submarginal lines of the under surface show through, and between them there is a very famt, 

 somewhat lighter undulate band, which scarcely contrasts at all in colour with the extreme marginal area 

 and is only separated from this by the distal line, but on the other hand is proximally more distinctly defined 

 by the darker median area. Posteriorly the marginal markings become quite blurred and the colour assumes 

 a uniformly dark tone for the whole breadth of the distal area. Hindwing black-brown, the fringes from the 

 apex nearly to the hinder angle whitish, basal area behind the grey costal zone grey-blue, in an oblique light
