 point just before the median vein. In the apical area 3 small wliite spots. $ unknown. — zelus Stick. Shape selus. 

 of O. cassiae, but somewhat larger, the apes of the forewing pointed. Upper surface dark brown, beyond the cell 

 of the forewing a sharply angled band placed as in the typical subspecies, but broader, fuller-margined, poste- 

 riorly tapering to a point not far from the distal margin directly before the submedian. In typical zelotes this 

 band is rectangular on the inner side, here only obtusely curved, but its peculiar position affords a cha- 

 racteristic and unmistakable distuaction from 0. cassiae. Equally unmistakable are the differences on the 

 imder surface. It shows in the forewing a grey-brown basal and cellular area with simple, undulate transverse 

 lines, arranged in peculiar figures, in the anterior part of the distal area a triangular patch with very fine 

 transverse striation. The huidwing has a strong violet tone and is quite finely watered with blackish wavy 

 lines and whitish shading. Scent-organs as in O. cassiae. Type: 1 c? in coll. Staudinger. Panama: Chiriqui. 

 0. tamarind! extends northwards to Mexico, otherwise its area of distribution coincides with that 

 of 0. cassiae, but the geographical branch-races differ more considerably, so that many forms from the An- 

 dean region are further removed from the name-type. The synonymy of the branch-races has not yet been 

 satisfactorily cleared up, as neither the earlier authors nor Stichel and myself observed that tamarind! Fldr. tamarindi. 

 (= xiphos Fruhst.) (61 b) came from Venezuela , and so it comes about that a more northerly race differing con- 

 siderably from tamarindi, and which I now call sikyon subsp. nov. (still figured, 61 b, under the old name sikyon. 

 tamarindi) passes as tamarindi and was also figured as such by Godman and Salvin in the celebrated 

 Biologia Centrali-Americana. Our figure of the $ is defective as regards the hindmargin, and an extended 

 red-bro-\^Ti tinge on the upperside of the hindwing is not brought out. In the ^ the upper surface is dark brown, 

 the distal margin anteriorly grey-brown. Band of the forewing dirty white, in its posterior part sometimes 

 browTiish, anteriorh' of approximately uniform breadth as far as the middle median vein, on the veins somewhat 

 incised on both sides, then constricted or narrowly interruj)ted by the middle median and the submedian, 

 thus posteriorly broken up into tM-'o sjDots, the second placed at the margin of the wing close to the hinder 

 angle, as an elongate, curved point. Hindwing Math a lighter patch or spots at the apex, dirty white or brownish, 

 and from there onwards vAih. a dull rust-red posteriorly washed-out, narrow undulate or curved band near 

 the margin. Anal area beyond the cell, about between the submedian and the upper median vein, more or 

 less strongh^ tmged with nist-red. Anterior eye-spot on the under surface ovalobliquely placed, distally ob- 

 liquely flattened, only narrowly margined with black-brown. $ larger, with broader wings, apex more ob- 

 tuse. Band of the forewing whitish as far as the posterior point, broader and more complete. Light patch 

 in the apex of the hindwing more distitict, becoming almost a band, the adjacent undulate line near the margin 

 better developed. ^ type from Tepic, West Mexico. Type of the $ from San Pedro Sula, Honduras, in coll.

 distributed throughout the whole of Central America to Colombia. — kleisthenes Fruhst. is the brilliantly co- Ideisthenes. 

 loured continuation of sikyon, from which it is distinguished by the more intensive velvety brown tmge in 

 the basal area of the forewing and the dark chest nut-brown discal part of the hindwing. The forewing bears 

 y further a more compact, lighter yellow transverse band of almost uniform breadth and the hindwing has a broad 

 terminal border, anteriorly light gold-yellow, posteriorly reddish. Under surface paler, more washed-out than 

 in jikyon, more broMii-yellow instead of grey-black. The yellowish subanal band of the forewing more strongly 

 marked, broader, more pronounced in colouring. Anal ocellus of the hindwing with light brown foreground.

 closely approximates to typical tamarindi Fldr. from Vg nezuela. as we frequently observe in species from eastern 

 Colombia, but cherocle-s is sharply distinguished from the name-type by the presence of a distinct, moderately 

 broad and only short marginal band on the hindwing, of reddish ochre-yellow colour, extending from the upper 

 radial to the upper median. The transverse band of the forewing is narrower, deeper ochre-yellow, strongly 

 narrowed at the middle median, the adjacent but well isolated spot more wedge-shaped; under surface darker 

 than in Venezuelan specimens, thejanal band more ample, somewhat more vertical. Upper Rio-Negro, East Colom- 

 bia, discovered by A. H. Fassl at 800 m. $ with light ochre-yellow transverse band on the forewing. Hindwing 

 with broad ochreoas distal border, running as a band to the upper median and from there to the anal angle as a 

 subterminal undulate line. Hindwing beyond the cell with a dark rust-red area. — corrosus Stick., in corrosiis. 

 my collection represented by three examples, has a somewhat narrower band on the forewing than in our figure 

 of xiphos, of dirty white to pale brownish colour, commonly abbi'eviated and narrowed posteriorly. Hindwing 

 uni'colorous chestnut-brown. 9 not differing materially from that of sikyon. Ecuador, not very rare. f. spadix spadix. 

 Stick, has the band of the forewing narrow, partially broken up into spots, brownisli mstead of white-yellow. 

 Singly among the normal form. Balzapamba, Ecuador, in July. — incolumis Stick. The wings broader. The incolumis. 

 oblique band of the forewing narrowed in the cell by tooth-like indentations of the ground-colour, much as in 

 quiteria, but in the (^ chalk-white and towards the anal angle more strongly narrowed and terminating 

 in a point at the submedian, in the $ light yellowish. Also on the under surface the band of the foreAving is 

 pure white; anterior eye-spot of the hindwing smaller than in bogotanus. In my collection from Pozuzo, Peru 

 and from Bolivia. — terenzius .subsp. nov. is based on the figure of a $ given by Staudinger m the Exotic terenzius.
