154 PTERONYMIA. By R. Hacjisch. 



iiiania. P- inania Hsch. is a similar, larger species with broader wings and deep black-brown margins. Be- 



hind the enil of the cell is placed at the costal margin an oljlong yellow-brown spot. On the under sur- 

 face there are numerous roundish white dots in the distal margin. This species, like the preceding, comes 

 from the border nf i-asti-rn Ecuador and Colombia. 



scrrala P. serrata Hscli. has stiU larger and broader, slightly yelhiwish wings with strongly dentate distal 



l)order. Thi' half-band at the end of the cell of the forewing is proximally widened. On the under sur- 

 face there art' (juadrate, yellow-brown, dark-margined spots at the distal margin of the hindwing l)etween 

 the white double s}iots. This species flies witli DismcnUis theudelinda (41 d) and other similar forms in the 

 mountain forests of the eastern chain of the Cordilleras of Ecuador at elevations of from 2 — 3000 m. 



IrrcKila. P. teresita Hew. (40 a. b), from eastern Ecuador, has broad wings, almost colourless in the o'. "with 



narrow dark margins. In the $ the wings ar<' dusted with yellowish, especially the hindwing. The latter 

 has much liroader distal border than in the ,^. On the under surface the margins are dark red-brown, 

 with white dots in the apex of the forewing and at the distal nuirgin of the hindwing. 



ci-ovia. In P. evonia Hsch., from Colombia, with shorter wings, the $ is of a yellow-brown colour, esjjeci- 



allv in tiie cell and at the end of the median of the forewing, and also at the proximal liorder of the 

 costal and distal margins and on the veins in the disc of the hindwing. The antenna is Idack. The 

 distal margin of tlie hindwing very broadly black. 

 sidmonn. P. sulmona Hew., from Ecuador, is said to l)e similar to terciita, with narrower margins and black 



antenna. The ba-si' of the forewing and the hindwing are dusted with red-))rown. On the under surface 

 there is a white spot in the apex of each wing ami the base of the hindwing is yellow. 



snesa. P. suesa Hew., from Ecuador, has transparent wings with yellowish sheen and narrow brown mar- 



gins and half-band across the end of the cell of the forewing. The club of the antenna is yellow-brown. 

 On the under surface the margins are yellow-ln'own, with 2 white dots in the apex of the forewing and a 

 row of double dots at the distal margin of the hindwing. 

 thabcna. P. thabena Hew. (40 a), from the eastern ridge of the Andes in Ecuador, has Viroad, transparent 



wings, the forewing with yellowish, tlie hindwing witli Iduish sheen. Unfortunately only ?$ are known of 

 this and the following similar forms, so that the genus cannot I>e exactly fixed. The marking recalls 

 forms of zerlina. The distal margin of the hindwing especially is very broad, and on the underside, where 

 it is red-brown, provided with whitish double (hits. The antenna has yeUow-brown club. — A local form 

 danUs. from Bolivia, which I call stantis form, nor., is distinguished by a narrow lilack half-band at the end of 

 acginvta. the cell of the hindwing. — From Ecuador comes anotlier similar form, aegineta Hew. It has the distal 

 margin ul tlie liindwing strongly dentate proximally and a proximally widened half-band at the end of the 

 rleohuUna. cell of the forewing. — cleobulina Hew., from Bolivia, probably also belongs here. It has the hindwing 

 like thabena, but in the cell of the forewing in addition a black bar, and at the black distal mar- 

 gin a projection in the direction of the somewhat prolonged half-band at the end of the cell. 



(Inilinilata. P. denticulata Hsch. (40 b), from Bolivia, has black margins and half-band at the end of the cell of 



the forewing; the distal margins are proximally dentate. The club of the antenna is yellow-brown. — In 

 dispacna. dispaena Hew. (40a), from the same district, the margins are lirown; sul)costal of the forewing reddish: 

 antenna black. In the $ the margins are broader and partly red-brown. 

 alida. P. alida Hciv. (40 a), from Venezuela, has narrower margins and a broad yellow half-band behind 



the uniformly broad half-l>and at the end of the cell. It closely resembles Episcada alidella. 

 calgiria. P. calgiria Schaus ( '? = dircennoides Stgr. i. I.), from Bolivia, is said to have transparent yellowish 



wings, with narrow dark brown margins and veins, and also curved half-band at the end of the cell of the 

 forewing; behind this there are yellowish spots at the costal and distal margins; also at the base and in 

 the end of the cell of the forewing. The distal margin of the hindwing is l)roadest at the 2'"' median vein 

 and in tlie apex. Club of the antenna yellow-brown. 

 tirirmirs: P. tigranes (lodm. d- S(dr. (40 b). from Central America, has colourless wings with narrow dark 



margins, somewhat broader in the f; in the forewing red-brown subcostal, and also a broad dark and 

 U'lwojcncs. white half-band at the end of the cell. — timagenes (lodm. ((■ Sale, from Mexico, at elevations of uji to 

 about 2000 m., differs from the preceding by the red-brown margins, only the inner margin of the fore- 

 iilcvirna. wing is blackish. The half-band at the end of the cell is mucli smaller. — alcmena Codni. d- Salr., from 

 Guatemala, is somewhat smaller, M'ith broader, reddish margins. The dark and the wiiite half-band at the 

 end of the cell are larger and more obliquely placi'd. 

 adlna. P. adina Hew., from Venezuela, is a similar species to tigranes, without red-brown sulicostal and 



with oblong white spot at the costal margin of the forewing. The costal margin of the hindwing is 

 strongly arched, the middle discocellular very long and curved. 

 eulijrci. P. eulyra Fldr.. from Venezuela, is said to l)e similar to Kpiscadu iilidelhi. but much smaller, with 



white submarginal spots on the under surface.
