PANARCHE. By G. Weymer. 275 



is a form of ulem/t Heir, in the male of which a row of brownish red -yellow spots runs from the costal to the 

 inner margin on the forewing above and is contiiniecl to the inner angle of the hindwing as a continuous 

 band, anteriorly broad, posteriorly tapering to a jioint. ■'? small round black spots are placed on this liand 

 in the anterior part of the hindwing. The under surface is similar to that of idema, but the bands are broader 

 and much purer white. Peru (Puente de Sigsi in the valley of the Rio Sonchi, 2.500 m.. June [Stlbel]). 



C. albomaculata ;S7;/r. ((JO a). May be known by the dull white, hi- or tripartite apical spot on the tilhotHdni- 

 upperside of the forewing. Beneath similar to ploas. The 9 is somewhat larger than the ^J and has an ad- ^"'"• 

 ditional small white spot on the costa. Beneath the apex and the distal margin of the forewing are more strongly 

 marked with silver-white than in the J. Bolivia and North Peru. 



C. cistene Heir. ((>0 b). Above brown with 6 small golden brown s])ots in a very sinuous row on the c'mtcnc. 

 forewing and indistinct spots on the hindwing. which scarcely stand out from the ground-colour. Beneath 

 the species may be recognized by the unusual shape of the brown median band on the hindwing (cf. fig.).

C. enyo Heir. (= auriga H.-ScJidff.) ((»0 c) is characterized by having the up])er surface of the hind- eiiyo. 

 wing almost entirely golden brown, which colour also extends to the base of the forewing. The under surface 

 is similar in markings to that of ahno (cf. figure, pi. flO c). but the aj^ex of the forewing and the entire hindwing 

 are light whitish grey and the 2 median stripes of the hindwing c^uite narrowly brown and distally bordered 

 with white. From the mountains of Caracas, Venezuela. This form is for the most part onlv represented in older 

 collections. The Colombian form more recently incorrectly distributed in collections under the name eiiifo 

 is much darker and should be calltd almo Thieme (()(• c). The hindwing is dark l)rown above, distally chestnut- ahno. 

 colour, beneath marbled with dark grey-bntwn. The $, which is likewise figured, has on the hindwing a golden 

 brown submarginal band and (tn the under surface of both wings the greater part of the distal margin broadly 

 golden brown. Colombia, Ecuador, Peru. Bolivia. 



C. chelonis Hew. (fiOd). Himilar to the preceding, but the forewing bears only 3 larger spots. Beneath cheloni'i. 

 the 2 apical spots are white. In the 5 tbese apical spots are contiguous above and the posterior spot, between 

 the median veins, is three times as large as in the q. Colombia ( Quindiu Pass and Cafion del Tolima, 2500 m.) 

 (Fassl). — rubeta Thieme, a form of chelonis, has the hindwing more rounded and the tails shorter, forewing rahda.

C. iduna Hew. (60 d, erroneously as murginalis). Resembles chelonis in the forewing, but the 3 spots iduna. 

 are white, not golden brown. In the anterior part of the hindwing there is a large, bright red-yellow or golden 

 brown spot, which does not reach the distal margin. Bolivia. — In the form marginalis Btlr. {= marginata marghmlis. 

 Kirby) the golden brown discal spot reaches the distal margin. Peru (Huancabamba and Cushi). 



C. peruviana Btlr. (60 d) was formerly regarded as a variety of iduna. According to Thieme it is a peruriana. 

 separate species. The white spot between the median veins of the forewing is not bipartite as in id una, 

 but consists only of one spot between the first and second medians. The anal angle of the hindwing is more 

 produced than in iduna and the disc almost entirely bright reildish golden brown. The distal margin is only 

 narrowly, the inner margin broadly dark brown. From Ecuador and the coast Cordilleras of Colombia. 



C. procellaria Thieme is the smallest species of the genus and resembles iduna, but the forewing is short- procc/laria. 

 er, the hindwing more rounded and the tail much shorter. The white spot between the median veins of the 

 forewing is bipartite as in iduna. The 2 white apical spots as in that species. Hindwdng dark brown with a fer- 

 ruginous submarginal spot in the apex, which is posteriorly lost in the ground-colour. From the Aconquija 

 Mountains near Tucuman. North Argentina.

This genus may be regarded as a connecting link between Corades and Polymastus. As in Corades, the 

 first median vein of the hindwing runs out into a long projecting point and the inner margin of this wing is as 

 straight as in that genus. On the other hand it differs widely from Corades in the straight costal and angled 

 distal margin of the forewing and the shaqi, pointed teeth of the hindwing, in which respects it approximates 

 more to Polymastus. It is, however, easily distinguished by the triangular hindwing. produced into a point 

 at the inner angle, the species of Polymastus having the hindwing shorter and broader, with the inner margin 

 rounded. The costal of the forewing is only slightly swollen. The 3 sj^ecies are rare and are indigenous to the 

 high mountains of Bolivia and Peru.
