PiiM. IS. X. 1910. PSEl>DOSCADA. By B. HaenscU. 161 



To Pseudoscada are referred a number of small . species, some of which are also externally very similar 

 to forms of Hypoleria. The sources of the Amazon and Brazil produce the most species, whilst from Central 

 America only a few species are known from the southern part. 



P. lavinia Hew. (= saturata;. Stgr.) (41 b), from eastern Colombia, much resembles Hypoleria vanilia, lavinia. 

 but is smaller and the shape of the wings is different, as is also the neuration. — An allied form is troetschi troetschi. 

 Stgr., from Costa Eica. The base of the forewing is colourless and the hindwing has only at the dark distal 

 margin a broad red-yellow stripe. The rest of the hindwing is colourless. 



P. florula Hew., from Caj^enne, has a similar pattern to the figured local form exornata Hscli. (41 b), exoniata 

 from British Guiana. It lacks, however, the red-brown colour in the distal margin of the hindwing, which 

 distinguishes exornata. On the under surface the margins in both forms are yellow-brown, exornata resem- 

 bles Napeogenes potaronus (35 f), which likewise flies in British Guiana, and also Hypoleria cyvio (41 a). 



P. egla Hew., from the Upper Napo, and the two following forms are very similar to Hypoleria on- egla. 

 cidia and its allies, as well as Napeogenes corena (36 b). egla has a broad yellow-red subapical band in the 

 forewing and at the hinder angle 2 separated, roundish vitreous spots betAveen the median veins. — ■ In 

 aureola Bates (41 b) the yellow-red band is still broader, so that at the hinder angle only one larger vitreous aureola. 

 spot remains. This form flies on the Upper Amazon. — ■ In sarepta Hew., from the Eio Negro, the j^ellow- sarepta. 

 red band is proximally bordered by a broad brown stripe, which extends from the end of the cell beyond 

 the 2. median vein to the hinder angle, as in Napeogenes corena. 



P. utilla Hew. (= pusio Godm. & Salv.) (41 b), from western Colombia and Ecuador, recalls Hijim- utilla. 

 leria niirza (41 a), but is considerably smaller and the whitish dots in the apex of the forew ng are not proxim- 

 ally surrounded with dark. 



P. seba Hew., from eastern Ecuador, has broader distal margins and no white dots at the distal margin seba. 

 of the forewing, on the other hand a faint white macular oblique band at the end of the cell. — A similar 

 form is timna Heiv. (41 c), from Venezuela and the eastern Andes from Ecuador to Bolivia. Here the white timna. 

 obhque band is stronger and the veins intersecting it are dusted with white. ■ — Another similar form is 

 arzalia Hew. (41 b), from Bolivia, with broader black apex, broader half-band at the end of the cell of the arzalia. 

 forewing and a broader, arched, white oblique band. 



P. adasa Hew. (41 c), from southern Brazil, is larger than the preceding, and has only a whitish spot adasa. 

 at the end of the ceU and whitish dots at the distal margin of the forewing. — acilla Hew. is a similar acilla. 

 form, but smaller, with pointed half-band at the end of the cell and narrower distal borders. — Jessica Hew. Jessica. 

 is the same size as adasa, but has a pointed half-band like acilla. It differs from the latter in the neuration 

 ■ of the hindwing, the lower discocellular forming a very acute angle with the median and ending proximally 

 to the middle discocellular, in acilla on the contrary distally to it. — ■ A fourth similar form is erruca Hew., erruca. 

 vrith the distal margins more strongly dentate at the veins and white half-band beside the end of the cell 

 on the forewing. It is said to be further distinguished from adasa by its more elegant form and to have 

 the end of the cell of the forewing placed almost transversely to the length of the wings. — All four forms 

 come from southern Brazil and are not easy to differentiate. They might even belong to different genera, 

 which can only be determined with certainty from the types. 



There follows now another group of forms whose (^^ are distinguished by the more pointed apex 

 of the forewing. 



In P. fallens Hsch. (41 c), from Central Brazil, the basal half of both wings is dusted with yellow, fallens. 

 especially in the $, which on account of the broader distal borders strongly resembles Pteronymia euriiea 

 (40 d). The half-band at the end of the cell of the forewing is strongly pointed. The base of the hindwing 

 beneath is red-brown, in euritea yellow. 



P. salonina Heiv. (41 b), from Bolivia, has colourless wings with dark brown margins and half-band salonina. 

 at the end of the cell of the forewing and also a yellowish oblique band towards the apex. — A very similar 

 form, with somewhat broader margins, flies also in Paraguay. — As trepotis fo7-m. nov. I designate a form trepolis. 

 like salonina with white instead of yellow oblique band on the forewing. It flies likewise in Bolivia. — 

 subtilis Hsch., from eastern Ecuador, is distinguished from salonina by yellowish dusting on the wings and suMilis. 

 weaker half-band across the end of the cell of the forewing. 



P. emyra Hsch., from Central Brazil, is a similar form to arzalia. The black apex of the forewing cmyra. 

 and the triangle at the end of the cell are broader. The 3. median vein remains black in the white oblique 

 band The distal margin of the hindwing is narrower.
