P. orchus Heir. (= orciis BtJr.) (59 c). Above dark brown witli four small grey spots t)efore the apex orchns. 

 of the forewing. On the under surface the species n)ay be knf)\\n by having several white sjjots 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 Westir. (59 c). Above brown, hindwing and a])ex of the forewing with slight reddish rordillcra. 

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

 neath. Bolivia. 



P. orcus Lair. (= orchamus Godt., porsenna Heii\) (fiO a). Above unicolorous dark lirown, only the apex orcus. 

 of the forewing somewhat lighter. The distal margin of the hindwing is weakly undulate. The V i« some- 

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

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

 brown patch. In.stead of the grey-brown colour of the J the $ has the ground-colour of the underside 

 of the hindwing light reddish brown, as also the distal margin of the forewing. The dark markings are all of a 

 dark red-brown colour. Colombia. Fas.sl took l)oth 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 brown border from the distal margin. Bolivia. — nepete Thienie is a further nepcte. 

 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, pamllela. 

 parallel with the distal margin, and all of uniform size, and the last but one is bordered with red at l)oth 

 sides. From Venezuela (Valencia). 



P. variabilis Btlr. is allied to orcus L<ttr. (porsenna Heir.). Above with green and reddish bronzy rarUihiUs. 

 gloss, without white s])ots, but with '.) dark spots at the apex of the forewing and 2 or 3 at the anal 

 angle of the hindwing. Beneath the red-yellow spot of the forewing is absent, the hindwing is more whi- 

 tish, the bands at the base and in the middle darker, with 8 white-pu])illed and light-bordered eye-spots 

 and a broad l)rown margin, proximally bordered with lilac. Peru. 



P. epidipnis T/z/f/zK' (tJO a). Above unicolorous brown. Beneath similar to orcA^/s //ew;., but the ground- cpidipnis. 

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

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



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

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

 somewhat produced in the middle. Above dark l)rown, 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. Statjdinger in the Berlin Museum. 



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

 it in having the median band of the hindwing l)eneath broader, shaiply 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 ferruginous. From Rioja in Pern. Coll. Staudinger in the Berlin Museum.

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 Burger hi his 

 ,,Reisen eines Naturforschers" as 500 m. to 2800 m., whilst according to Thieme they ai'e confuied to particu- 

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

 fly singly and are not common. 



C. pannonia Heic. (= ichthya H.-Schdff., $ = fluminalis Btlr.). Above unicolorous brown. Forewing pannonia.
