156 PTERONYMIA. Bij B. Hacnsch. 



fizcUa. P. fizella Bdv.. from Guatemala, is said to be very similar to Itliomia agnosia (37 f), with the mar- 



gin of the forewing widened towards the apex and quadrate spot at the end of the cell. The white 

 oblique band reaches the distal margin. 



artciia. P. artena Hew. (40 c) is said to come from Mexico, but a similar form is common in the 



eastern Andes from Colombia to Peru. artena has about the size and appearance of tigranes and adina. 

 The black half-band at the end of the cell of the forewing is proximally forked, the white l)and ends at 

 the third median vein. In the apex of the margins, which are red-brown beneath, are placed in the fore- 



olimba. wing 2 white dots, in the hindwing only one. — olimba Hscli.. f)-om southern Peru, is distinguished by a 

 yellow base to the hindwing beneath and yellow underside to the abdomen, which is grey in artena. 



dcrnma. P. derama Hsch., also from the border of Peru and Bolivia, recalls Pseudoscada salonina (41 b). 



The wings are diaphanous with narrow margins. Across the end of the cell of the forewing is placed a 

 wedge-shaped black spot and towards the apex a delicate yellow-white half-band, cut off at the 3''^ median 

 vein. On the under surface the margins are brown-red with 3 whitish dots in the apex of the forewing. 

 ajranitt. P. afrania Hpfr., from Bolivia, resembles Miraleria sylveUa (40 e) and Episcada salvinia (39 d), 



without the red-l)rown colouring of the subcostal and median of the forewing. The narrow black margins 

 are broadest in the apex and at the inner margin of the forewing. Beside the narrow, uniform black band 

 at the end of the cell is placed a similar white one. 

 apia. P. apia Fldr., from Colombia, is similar to tigranes, with narrow margins and pointed dark half- 



band at the end of the cell of the forewing, and also a broad white one beside it. Subcostal red-brown. 

 On the underside the costal margin of the hindwing is yellowish at the base. 

 asopo. P. asopo Fldr., from Venezuela and Colombia, is smaller than artena. The half-band at tlie end of 



the cell of the forewing is triangular: the white patch beside it proportionally broader. On the under sur- 

 face there are 3 whitish spots in the apex of the forewing, 2 in that of the hindwing, as well as 3 indi- 



asellin. stinct ones at the distal margin. — asellia Hpff. (= andreas Weeks) (40 c), from Peru and Bolivia, is a 



similar form with the triangular spot at the end of the cell broader costally and beneath not blackish but 



rust-brown. Moreover the white marginal spots are absent and the 2'"' median vein of the forewing is 



asclUala. dark-margined. — In aselliata HscJi., from Ecuador, the white oblique band of the forewing is broader and 



reaches the 2'"' median vein; also the white patch at the hinder angle is larger and in the 9 united with 



the oblique band. 



alissa. P. alissa Flew. (40 c), from west(n-n Ecuador, has a somewhat curved half-band at the end of the 



cell of the forewing and a small, white, black-edged spot at the costal margin. The apex of the forewing 



aUssana. is more strongly rounded. — In alissana HsrJi. the forewing has also a broad white oblique Ijand, which, 



however, is semitransparent and not sharply cut off at the 2'"' median vein, as in the similar aselliata. It 



flies likewise in western Ecuador. 



vestilla. P. vestilla Hew., from the Upper Amazon, has V>roader dark margins; the dark oblique l)and at the 



end of the cell is continued beyond the 2'"' median vein to the distal margin. Behind it follows towards 

 the apex a _yellow oblique band. There is in addition yellow dusting in the end of the cell and at the 



ncaya. hinder angle of the forewing, as well as in the anterior half of the hindwing. — In ucaya Hsclt., from the 



spnrsa. Ucayali River, the yellow olilique band is whitish. — Sparsa Hscli. is another form of restilla, from the 

 Upper Napo in Ecuador. The yellow dusting of the wing is much stronger, especially in the whok' 

 of the hindwing, where also the veins stand out strongly yellow. 

 I'lurii. P. laura Stgr. (40 d), from Colombia, is one of the few brightly coloured small species. It is simi- 



lar in colouring to Hypoleria vanilia (40 g) and Pseudoscada lavinia (41 b). The half-band at the end of 

 the cell is somewhat emarginate towards the apex and encloses a white patch. In the dark shaded apical 

 area of the forewing are placed in addition a number of whitish dots at the distal margin and in the disc. 

 The hindwing, especially at the distal margin, is red-ln-own (more strongly in the $) and with dark mar- 

 gins at the apical half. 

 agaUu. '*• ^'ctta Hew. and agalla Godm. d- Salv. (40 d) are 2 very similar forms, the formiT from Colombia 



and Venezuela, the latter from Panama and Costa Rica. agalla has a sharply defined yellow oldique band 

 at the end of the cell of the forewing and roundish spots before the distal margin. In aletta the oblique 

 band is composed of indistinct spots, between which the lower radial remains dark. On the yellow-brown 

 hindwing the veins in agalla are bright red-brown, in aletta blackish in the distal half. Both forms have 

 alope. a broad red-brown inner margin to the forewing, whilst in a third form, alope (lodm. <f »SV//!'., from Panama 

 and Venezuela, which is said to be otherwise similar to aletta. the inner margin remains blackish. Another 

 species similar to these forms is Episcada polita (39 e). 

 i^'f^"- P. lilla Hew. (40 c) has in addition to a yellow obhque liand yellow dusting in tlie cell of tlu- fore- 



wing and the cMastal half of the hindwing, and yellow dots at the distal margin of the forewing. On the 

 under surface the margins are brown with yellow-brown markings, only the base of the hindwing is reddish 

 yellow-brown. In the apex of the forewing are placed beneath 4 white dots, in the distal margin of the 

 hindwing 5 oblong double dots. In western Ecuador at the foot of the Andes.
