MYGONA; PROBOSCIS. By G. Weymer. 269 



a chestnut-red spot between the median veins of the forewing, by which the species may be recognized. Of the 

 3 silvery transveree stripes on the iinderside of the hind\^'ing the proximal one is quite straight. Bolivia (Yungas 

 de la Paz). Rare, only one ^ in Thieme's collection. O 



C. mena Gr.-Sm. (58 a). Above unicolorous brown, with bronzy gloss. Beneath the silver markings mena. 

 at the apex of the forewing and the silver bands on the hindwdng are much darkened by brown dusting. There 

 is mostl}^ here on the fore^ning a small orange spot between the 2nd and 3rd median veins, which was wanting 

 in the example figured. Bolivia (Yungas de la Paz, San Jacinto, San Antonio, Cillutincara). 



C. clethra Thieme. Similar to the preceding, but smaller. Above glossy bronze-brown. Foremng cMhra. 

 beneath A^ithout gloss, dark bro\^^l, only the apex somewhat silvery. A small chestnut-red spot between 

 the 2nd and 3rd median vems. Hind^^ang beneath likemse dark brown, only the anterior half somewhat 

 silvery. There is no trace of transverse bands, on the other hand all the veins are black and each cellule bi- 

 sected longitudinally by a black Ime, forming a pattern similar to that of the Actinote species. At the 

 base are placed some small red spots. From Peru (Villanota and Chanchamayo). 2 examples in coll. Staxt- 

 DEsGEE (Berlin Museum). 



C. schreineri Foefterle (= lemur Thieme) (58 a). Above pale yellowish brown with 2 rows of light schreineri. 

 ochre-yellow spots and dark grey-brown base. The hindwmg is margined with reddish in the anal part. The 

 under surface is similarly marked to the upper, except that the spots on the hindwing have a dull sil- 

 very gloss and in the basal half of this wing is placed a silver band partly broken up into spots. The ground- 

 colour of the hindwing beneath is yellomsh bro'mi, finely striated with dark brown. Peti'opolis (South Brazil). 



49. Genus : OTj^goiia Thieme. 



The costal margin of the fore'wing is long, its anterior part produced distad, and the distal margin con- 

 sequently excised below the upper radial. The hindTidng is strongly dentate, the tooth on the 2nd median vein 

 broader and stronger than the rest, but not produced into a tail. The costa of the hindwing is not emar- 

 ginate, but smooth and rounded. In the scheme of markings of the under surface the species are all very simi- 

 lar. On the hindwing a white spectacle-shaped spot and 3 white dots forming a triangle are nearly always pre- 

 sent and on the fore"vring mostly three chestnut-red or liglit brown dots. The species have been described 

 as Pronophiki or Oxeoschistus. 



M. prochyta Heiv. (= Oxeoschistus erebus Gr.-Sm.) (57 e). Above unicolorous dark brown, only the base prochyla. 

 and apical part of the forewing somewhat lighter. The $ has an indistinct, somewhat lighter brown costal 

 spot and sometimes 2 reddish grey spots between the median veins of the forewing. Bolivia (Yungas de la 

 Paz). — chyprota Gr.-S>7i. (57 e) may probabty be regarded as the Peruvian form of prochyta. It is somewhat chyprota. , ^ 

 smaller, on the under surface quite similarly marked, only more red-brown. On the upper surface the basal 

 part of the wings is entirely red-brown, the distal part spotted with red-brown. From Peru (Guzco, Cal- 

 langa, Vilcanota). 



M. thammi Stgr. (57 e upper and under surface). Similar to the preceding species, but the hindwing tliammi. 

 almost entirely chestnut-red above, with 3 black spots before the margin. The under surface very varie- 

 gated. Peru (Chanchamayo, Cushi, Hunancabamba). 



M. poeania Hew. Forewing above unicolorous brown, hindwing brown, the anal part occupied by poeania. ""^ 

 a red-bro-i^Ti area, which reaches to the middle of the wing and is traversed by a brown submarginal line. The 

 under surface is quite similar to the preceding species. From Ecuador. Rare. 



M. irmina DM. (58 a). May be known by the large white spot of the hindwing on the upper surface, irmhm. 

 which is otherwise dark browTi. The under surface is very similar to that of prochyta, except that the apex 

 of both wings is marbled with lighter grey-brown. In the $ the distal margin on the upperside of the hindwing 

 is narrowly brown-red, a brown-red spot is placed before the apex and 2 indistinct spots between the median 

 veins of the forewing. Venezuela (Merida), Colombia (Bogota, Rio Vitaco). 



50. Genus: Proboscis Thieme. 



This genus is distinguished by having the apex of the forewing falcate and strongly recurved posteriorly. 

 The costa of the hindwing is concave. The distal margin of this wing is dentate and forms a short tail on 

 the 2nd median vein. Only one Colombian species, which Hewitson made known as a Pronophila. 



P. propylea Hew. (58 b). Forewing beneath brown, with red-brown base and apex and 3 brownish propyJca. 

 yellow spots before the distal margin. Hindwing beneath yellowish brown with brown median band and 

 brown margin, in which is placed a row of whitish yellow spots and dots. Colombia. The species is very rare and 

 was unknown to Thieme in nature. Fassl took a specimen in the neighbourhood of Muzo at 2000 m.
