160 PSEUDOSCADA. By B. Uaenscli. 



forewing and 3 whitish dots before the distal margin. The vitreous areas of both wings are shghtly 

 shaded with brownisli. 

 oncidia. H. oncidia Bates, from the Upper Amazon, has similar markings to orolina; it is somewhat smaller 



and has whitish dusting in the end of the cell and before the distal margin of the forewing, and also in 

 tenera. the disc of the hindwing. — A very nearly allied form is tenera Smka^ from Pebas, which has 3 white 

 dots between the median veins of the forewing, whilst only 2 of these are said to be present in oncidia. — 

 quadrona. In a further form from Yurimaguas, on tlie Upper Amazon, which I call quadrona form, nov., the yellow- 

 red band is only very narrow and between it and the broad band at the end of the cell of the forewing 

 there is another whitish patch. 

 cymo. H. cymo Hb7i. (= galita Hew.) (41 a) has a dark half-band across the end of the cell of the fore- 



wing and adjoining it a white patch. The distal margin of the hindwing is red-brown, with dark edges. 

 On the under surface the distal margins together with the costal margin of the hindwing are light red- 

 indecora. brown with dark edges. — In the form indecora Hscli. (= sylphis Kaye), from British Guiana, the red- 

 brown colour at the distal margin of the hindwing is absent. At the distal margin of the forewing there 

 are white dots, and the margins of the under surface are yellow-brown. 

 garleppi. H. garleppi Hsch. is similar to the preceding, with narrower white patch at the end of the cell and 



without the whitish dots at the apex of the forewing. 

 famina. H. famina Hsch. (41 a), from Peru, has the wings more strongly dusted with white and an angular 



smoke-brown spot in the cell of the forewing. On the under surface the dark margins are variegated with 

 oriana. yellow-brown. — In oriana Hew., from the Upper Amazon, the costal and distal margins of the hindwing 

 are much broader and leave in the disc only a vitreous longitudinal band, just as in Leucothyris onega. 

 Virginia. H. Virginia Heiv. (40 g), from the Amazons, has smoke-brown wings with broad dark margins and 



broad apex to the forewing. Across the cell of the latter is placed a wedge-shaped oblique band and 

 towards the apex a broad, segment-shaped, white band. 

 xenopJiis. As H. xenophis spec. nov. I designate an isolated species from the Eio Ucayali, with elongate, 



yellow-dusted wings, which recalls Episcada ca7nlla (39 c). The forewing has before and behind the end of 

 the cell a dark pointed half-band, as well as dark margins. The greater part of the hindwing is dusted 

 with yellow; it has likewise dark margins. On the under surface all the margins are red-brown, dark- 

 edged, without white marginal dots. 

 coenina. H. coenina Hew. (40 g) differs considerabW from most of the other forms l)y the pointed apex of 



the forewing and the absence of marking at the end of the cell. The wings are dusted with grey and have 

 adornata. fairly uniform black margins. The latter are black also beneath. — In ab. adornata Hsch. the mar- 

 gins are bright red-brown on the underside, especially at the base and the anal angle of the hindwing. 

 veronica. H. veronica Weym., from Colombia, is larger than coenina; the distal margins are proximalty den- 



tate. Across the end of the cell of the forewing there is a black triangle and at the anal angle of the 

 hindwing a rust-coloured oblong spot. The species resembles Pteronymia thabena and tucuna. 

 oreas. H. oreas Weym. (41 a), from southern Brazil, has broad, glossy bluish white wings with dark mar- 



gins and on the forewing whitish dots at the distal margin. The half-band at the end of the cell is broad, 

 proxima. especially in the $. — A nearly allied form is proxima Weym., likewise from South Brazil. Here the 

 wings are colourless, the margins above grey-brown and beneath yellow-brown. In oreas the margins are 

 red-brown beneath. 

 viirza. H. mirza Heiv. (= lavinia Hew. p., ryphaeno Oberth.) (41 a), from western Ecuador, has a narrower 



half-band in the forewing and whitish dots at the end of the cell and the distal margin, of which those 

 riffarUii. before the apex are proximally bounded by a weak oblique band. — riffarthi Hsch., from Ecuador, has 

 similar, but stronger markings. But here the forewing is further distinguished by a white half-band be- 

 tween discocellular and apex. 

 cassolis. j^^ cassotis Bates, from Guatemala, and rliene Godm. d- Salv. (41 a), from Panama, are very similar 



to each other. In cassotis the half-band at the end of the cell of the forewing is proximally forked, in 

 rhene pointed. Moreover, the cell of the hindwing is said to be much longer in rhene, the lower radial on 

 cajona. the contrary very short. — • cajona Hscli., from south-eastern Peru, is another similar form with broader 

 black apex to the forewing and without reddish subcostal. 



32. Genus: Pseudoscada Godin. d- Salv. 



This genus differs from Hypoleria in the absence of the oblong scent-spot in the (J. Costal and 

 subcostal are almost entirely coincident. The separation of the two genera, however, cannot be rigidly car- 

 ried out, as in some species an oblong raised patch combined with an indistinct costal indicate the tran- 

 sition. On the other hand Pseudo.scada shows also relationship to Hymenitis, so that it is doubtful to 

 which genus some species belong.
