P. orchus Heu\ (= orciis Btlr.) (59 c). Above dark brown with four small grey spots before the apex orchiis. 

 of the fore wing. On the under surface the species may be known by having several white spots before the apex 

 and a red-yellow one in the middle of the forewing and at the anal angle of the hindwing a fine black dentate 

 line on a white ground. Colombia. 



P. Cordillera Westw. (59 c). Above brown, hindwing and apex of the forewing with slight reddish cordillera. 

 brown gloss. This beautiful species may be recognized by the chestnut-red basal half of the forewing be- 

 neath. Bolivia. 



P. orcus Latr. (= orchamus Godt., porsenna Hew.) (60 a). Above unicolorous dark brown, only the apex orcus. 

 of the forewing somewhat lighter. The distal margm of the hindwing is weakly undulate. The $ is some- 

 what larger (expanse 78 mm.) and somewhat lighter brown and has on the upperside of the forewing 4 round 

 black spots, corresponduig in position to the eye-spots of the under surface. These spots are placed in a yellowish 

 brown patch. Instead of the grey-brown colour of the ^ the $ has the ground-colour of the underside 

 of the hmd\^■ing light reddish brown, as also the distal margin of the forewing. The dark markings are all of a 

 dark red-browai colour. Colombia. Fassl took both sexes at the Alto de los Ances at an altitude of 2200 m. 

 and at the Quindiu Pass (2600 m.). — locuples Thieme is a form of orcus in which the under surface of the locuplcs. 

 forewing bears a second small red-yellow spot near the costa. On the upper surface the lighter brown api- 

 cal shade is separated by a bro^^ai border from the distal margin. Bolivia. — nepete Thieme is a further nepeie. 

 form which has on the upper surface a light yellow-brown macular band with slight golden gloss, ex- 

 tending from the costa to the 2nd median and also marked on the underside as a brownish white area. Other- 

 wise the under surface does not differ from that of orcus. From Peru (Chanchamayo). — A third form is 

 parallela Thieme. In it the 4 ocelli on the forewing beneath are placed in a straight line one below another, parallela. 

 parallel ^rith the distal margm, and all of uniform size, and the last but one is bordered with red at both 

 sides. From Venezuela (Valencia). 



P. variabilis Btlr. is allied to orcus Latr. (porsenna Hew.). Above with green and reddish bronzy variabilis. 

 gloss, without white spots, but with 3 dark spots at the apex of the forewing and 2 or 3 at the anal 

 angle of the hind-wing. Beneath the red-yellow spot of the forewmg is absent, the hindwing is more whi- 

 tish, the bands at the base and in the middle darker, with 8 white-pupilled and light-bordered eye-spots 

 and a broad brown margin, proximally bordered with lilac. Peru. 



P. epidipnis T/r("e??ie (60 a). Above unicolorous brown. Beneath similar to orc/msi/eii'., but the ground- epidipnis. 

 colour of the hindwing is throughout light grey without white, only at certain angles a slight silvery gloss 

 is visible. The median band is nearly straight. Merida, Venezuela. 



P. lucomo Thieme. A large species. The costal margin of the forewing is somewhat longer, hence the lucomo. 

 distal margin is more oblique than in the other species. Hindwing strongly dentate, its distal margm 

 somewhat produced in the middle. Above dark brown, before the apex somewhat lighter. Beneath similar 

 to orchus Hew., but without the red-yellow spot on the forewing. On the hindwing the dark median band is 

 bordered with white on both sides at the costal margin; at the inner margin a large white spot is placed 

 before it. From Vilcanota in Peru. Coll. Statjdingee in the Berlin Museum. 



P. colocasia Thieme is similar to the preceding species, unicolorous brown above, and differing from colocasia. 

 it in having the median band of the hindwing beneath broader, sharply defined on a silvery ground, basally 

 bent round and not reaching the inner margin. The anterior part of the distal margin of this wing is broadly 

 bordered with ferrugmous. From Rioja in Peru. Coll. Stattdingbr in the Berlin Museum. 



56. Genus: Corades DM. & Hew. 



The species of this genus may be known at a glance by the elongate form of the hindwing, the anal 

 margin of which runs out in an almost straight line into a long tail, which is formed by the first median 

 vein. Consequently the cellules at the inner margin are very narrow. Only in a few species the tail is shorter. 

 The distal margin of the forewing is plain or rounded, that of the hindwing likewise plain or slightly undulate. 

 The costal vein of the forewing is swollen at the base. Two subcostal veins arise before the end of the 

 cell on the forewing. The middle discocellular forms on both wings an angle proximad, from which arises 

 a small recurrent vein. The rather long palpi and the eyes are finely haired. The butterflies are of medium 

 size, the upper surface unicolorous black- brown or partly red-brown or yellow- brown, sometimes with 

 yellow or white spots. The under surface is often light and dark marbled, the hindwing then agreeing in 

 colouring with the apex of the forewing. Sometimes silvery stripes are present. Their range of distribu- 

 tion embraces the Andes from Venezuela to Bolivia, only one species reaches North Argentina. Statements 

 differ as to the vertical distribution. The altitude at which the Coracles species fly is given by BiJEGER in his 

 „Reisen eines Naturforschers" as 500 m. to 2800 m., whilst according to Thieme they are confined to particu- 

 larly high altitudes and Fa SSL gives the lowest elevation as 1400 m., the highest as over 3500 m. They always 

 fly singly and are not common. 



C. pannonia Hew. {— ichthya H.-Schdff., $ = fluminalis Btlr.). Above unicolorous brown. Forewing pannonia.
