parts of Peru. It approximates in its small size to the Trinidad race and differs from the type-form in the brighter, 

 more brilliantly glossy reflection on the basal part of both wings, which are also traversed by very narrow 

 inconspicnons longitudinal bands. 3y these praxsiodus may also be at once separated from pamj}eiro 

 FruJisf., m which the bright ochre-yellow longitudinal bands are always conspicuous. Under surface very closely 

 resembling oheron Btlr., but with still darker striation, the anal eye-spots very much smaller, the whitish dusting 

 in the median and submarginal areas nearly obsolete. — pheidriades subsp. nov. ^ somewhat smaller than -pJieidriades.

 with the bands of the forewmg more grey instead of brightly coloured. Egg (accordmg to Kaye and Guppy) 

 spherical, whitish, with regular longitudinal ribbing. Young larva whitish, dorsal surface with 2 red double 

 stripes at the sides, head large, brown, strongty hairy, a long, branched tail-fork; after the first moult the head 

 more slender, reddish, with branched horns; upperside of the body green with a brown stripe and a white 

 upper lateral longitudinal line, below the stigmatal line striped with white and reddish. Tail-fork simple, on 

 the 6th segment a thorn-like point. After the second moult the body becomes brownish, with two dorsal pomts 

 on the 6th and Sth segments, and shows an upper lateral stripe and on the separate segments brownish oblique 

 stripes decreasmg posteriori}'; stigmatal lines as before. The full-grown caterpillar is cylmdrical, tapering 

 anteriorly and posteriorly; head broad, flat, obliqiiely sloping anteriorly, striped with black-brown, with 2 pairs 

 of shorter and 1 pair of longer horns; the first segments of the body strongly grooved transversely, on the 

 dorsum two short points; ground-colour of the body dirty M'hite, dorsal stripe blackish, anteriorly cleft, at 

 both sides an upper lateral dark double Ime, below this a greenish lateral stripe, from which on the separate 

 segments oblique stripes ascend anteriorly, below it a reddish brown stigmatal stripe, bordered with white 

 on both sides. Ventral surface and legs dirty green, fork shortened. Entire length 115 mm., length of the fork 

 9 mm. Trinidad; St. Vincent (British Museum). — ■ polyxenus /S^jc/t. Transverse bands of the forewing somewhat 'polyxenus. 

 widened and particularly bright oclu'e-yellow, more rarely somewhat darker. The band at the cell anteriorly 

 somewhat dentate, then nearly straight, proximally but little incised at the veins. The band near the distal 

 margin strongly zigzag, anteriorly the separate teeth more or less diffused proximally on the veins. Distal 

 margin of the hindwmg anteriorly more broadly, posteriorly narrowly dusted with whitish. On the under- 

 side of the hindwing the posterior eye-spot is as a rule especially large and broadly ringed with whitish yellow. —

 gloss. Cell of the forewing mostly shot with blue thi'oughout, costally and basally paler, almost grey-blue. 

 Transverse bands ochre-yellow, the tone of colour inconstant, mostly not quite pure, sometimes even strongly 

 darkened, both on the whole narrow, the one adjoining the cell somewhat dentate anteriorly, from the lower 

 radial onwards nearly straight; it terminates at the lower median vein and its posterior part is obsolescent. 

 The submarginal band anteriorly somewhat sinuous, then at most slightly undulate and in its general course 

 but little curved. This also is somewhat more indistinct posteriorly, likewise terminating at the lower median . 

 vein or somewhat before it. The blue basal area of the hindwing extended to beyond the end of the cell and 

 nearly reaching the hinder angle, strongly iridescent, but paler anteriorly. On the subcostal, close to the precostal 

 cell, is placed a flattened, blackish scent-scale spot, with somewhat bluish reflection in a side light, which ex- 

 tends on to the cell. Fringes of both wings whitish yellow, distal margin of the hindwing not at all or only quite 

 narrowly dusted with whitish. $. Considerably paler in colour. Forewing less dusted with blue, the transverse 

 bands lighter, broader, sometimes more strongly dentate and undulate. Hindwing with broad grey -brown or 

 dirty whitish costal area, in which the striation of the under surface shows through more distinctly. Hence 

 the blue basal area is somewhat restricted anteriorly. Distal margin of the liindwing somewhat more, but 

 still only slightly dusted with whitish. Larva very similar to that of C eurilochus, but smaller and proportion- 

 ately thicker. Body with fine transverse grooves, on the dorsum with 6 weak, spine-like points, otherwise 

 covered with short, stiff hairs. Ground-colour yellow-brown with black dorsal line, which is forked anteriorly. 

 The body laterally striped with alternate light and dark brown and on the upper half with short brown oblique 

 stripes. Ventral surface dark brown. Head of the colour of the body, with five broad dark stripes. Pupa com- 

 pact, su.spended, at the vertex with narrow helmet-like comb, of yellowish ground-colour, marked with brown, 

 with two very conspicuous silver spots on the wing-cases. Guiana, Brazil, Amazons, Para, Rio de Janeiro.

 Museum. — • pampeiro Fruhst. is smaller, lighter, the blue reflection stronger, but the blue dusting on the pampeiro. 

 forewing somewhat reduced, the distal part of the cell mostly remaing brown. Transverse bands pure orange- 

 yelloAv, the proximal but little sinuous or dentate, posteriorly somewhat duller, the submarginal more strongly 

 sinuous and dentate. Distal margin more strongly excised, border of the hindwing very broadly dusted with 

 yello^vish white in curves. The large ocellus on the underside of the hindwing shows a tendency to posterior 

 elongation. 2 paler, the bands on the forewing lighter, the submarginal broader. Distal margin of the hindwing 

 bordered with white, in the interspaces between the veins broad yellow-white crescentic spots. Paraguay.
