 point just before the median vein. In the a])ieal area 3 small white spots. $ unknoAvn. — zelus HtidL Shape ::ehis. 

 of O. cn.sviue, but somewhat larger, the apex of the forewing pointed. Upper .surface dark brown, beyond the cell 

 of the forewing a sharply angled band placed as in the tyj)i(.'al subspecies, but broader, fuller-margined, poste- 

 riorly tapering to a point not far from the distal nuxrgin directly before the submedian. In t_yi)ical zelote.s this 

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

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

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

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

 transverse sti'iation. The hindwing has a strong violet tone and is quite finely watered with blackish wavy 

 lines and whitish shading. Scent-oi'gans as in O. cnssiae. Type: 1 j* in coll. Staudinger. Panama: Chiriqui. 

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

 of (J. ca.^.siiii:, l)iit the geograjihical branch-races differ more considerably, so that many forms from the An- 

 dean region are further removed from the name-ty[3e. The synonymy of the branch-races has not yet been 

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

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

 siderably from tamarindi, and which I now call sikyon sub.s]). nov. (still figured, (il b, under the old name silyon.. 

 tiintariiidi) 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-brown tinge on the upperside of the hindwing is not brought out. In the j the upper surface is dark brown, 

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

 brownish, anteriorly of approximately uniform breadth as far as the middle median vein, on the veins somewhat 

 incised on both sides, then constricted* or narrowly interrupted by the middle median and the submedian, 

 thus posteriorly I:)roken up into two spots, the second placed at the margin of the wing close to the hinder 

 angle, as an elongate, curvt'd point. Hindwing -witli a lighter patch or sjjots at the apex, dirty white or brownish, 

 and from there onwards with a <lull rust-red ])osteriorly washe(l-out. nari'ow undulate or curved band near 

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

 less strongly tinged with mst-red. Anterior eye-spot on the uniler 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 jioint, broader and more complete. Light patch 

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

 better develojjed. (^ tyjJe from Tepic, West Mexico. Type of the $ from San Pedro Sula, Honduras, in coll.

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

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

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

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

 terminal border, anteriorly light gold-yellow, joosteriorly reddish. Under surface paler, moi"e washed-out than 

 in sikyon, more brown-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 Venezuela, as we frequently observe in species from eastern 

 Colombia, but cherocles is shaqjly 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 baud 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 s]>eciniens, the anal band nujre anqjle, somew hat more vertical. Upper Rio-Negro, East Colom- 

 bia, discovei-ed by A. H. FAs.sLat SOOni. $ with light ochre-yellow transverse band on the forewing. Hindwing 

 with broad ochrcous distal border, running as a band to the u])i)er median and from there to the anal angle as a 

 subterminal undulate line. Hindwing beyond the cell with a dark rust-red area. — corrosus Stirh., m corrosus. 

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

 of xiphos, of dirty white to {^ale brownish colour, commonly abbreviated and narrowed posteriorly. Hindwing

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

 ([Hiteria, but in the (J 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 forewing is 

 pure white; anterior eye-s]i()t of the hindwing smaller than in bogotanus. In my collection from Pozuzo, Peru 

 and from Bolivia. — terenzius suhsp. nov. is based on the figure of a $ given by Staitdinger in the Exotic lercn;:iiis.
