Pnbl. IS. X 1910. PSEUDOSCADA. By B.. Hacnsvh. 161 



To Bsciuhscada are referred a number of siviall species, some of which are also externally very similar 

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

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



P. lavinia Hew. (= saturata Stgr.) (41 b), from eastern Colombia, much resembles Hijpolcrid rnnilia, larinin. 

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

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

 margin a In'oad red-yellow stripe. The rest of the hindwing is colourless. 



P. florula Hciv., from Cayenne, has a similar pattern to the figured local form exornata H.'icli. (41 b), {."ol-iiaia 

 from British Guiana. It lacks, hoAvever, the red-brow"n colour in the distal margin of the hindwing, which 

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

 bles Napeogenes potaronus (35 f), which likewise flies in British (ruiana. and also Hypolcria eymo (41 a). 



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

 cidia and its allies, as well as Napeogenes corena (3C ]>). egla has a broad yellow-red subapical band in the 

 forewing and at the hinder angle 2 separated, roundish vitreous spots between 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 aurcoli. 

 spot remains. This form flies on the Upper Amazon. — In sarepta //('(/■., from the Eio Negro, the yellow- surepta. 

 red band is proximally bordered by a broad lirown 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 Godvi. tO Salp.) (41 b). from western Colomliia and Ecuador, recalls Hypo- ulilla. 

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

 allv surrounded with dark.

imna. 



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

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

 form is timna Hew. (41 c), from A'enezuela and the eastern Andes from Ecuador to Bolivia. Here the white tb 

 oblique 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 o])lique band. 



P. adasa Hew. (41 c). from southern Biazil, is larger than tiu' ^'receding, and has only a whitish spot adasa. 

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

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

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

 of the hindwing, the lower discocellular foiniing 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., crnwn. 

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

 on the forew-ing. It is said to be further distinguished from adasa by its more elegant form arul to have 

 the end of the ceU 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 fr(uu the types. 



There follows now another grouj) of fm-nis 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 Pteronyinia euritea 

 (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 Hew. (41 b), from Bolivia, has colourless wings with dark brown margins and half-band .'^alo)iina. 

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

 form, with somewhat liroader margins, flies also in Paraguay. — As trepotis form. nor. I designate a form Ircpulis. 

 like salonina with white instead of yellow obli(iue band on the forewing. It flies likewise in Bohvia. — 

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

 weaker half-band across the end of the (•(■11 of the forewing. 



P. emyra Hsch., from Central Brazil, is a similar form to nr:alia. The black apex of the forewing emura. 

 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.
