144 HYPOSCADA. By R. Haenseh. 



singularis. C. singularis Beb. is a form from western Ecuador with narrow, delicate wings. The yellow oblique band 



is narrow, not dentate towards the apex, provided with a projection towards the base. The median band of 



the forewing is broad, shadowy. The antenna is dark with brownish club. 



melano- q^ melanoptera Hew., from Ecuador, is a peculiar form with blackish wings, the cells of which are trans- 



^ ^^^' parent yellowish brown, as also 3 larger spots at the distal margin of the forewing. On the under surface there 



are sorne quadrate reddish spots at the distal margin of the hindwing. It appears to be a melanistic aberration. 



nise. C. nise Cr. (? = selene Cr.) (38 b ^, $) has a yellowish, broad oblique band in the forewing, reaching 



to the inner angle, where it is strongly denticulate. The ground-colour in the ^J is faintly red-brown, in the $ dark 



red-brown. The hindwing has a narrow median band, which is connected with the costal margin in bow-shape 



and in the cJ forms the border of a transparent, hght longitudinal band, nise flies on the Lower Amazon, as 



peruensis. well as in Guiana and Venezuela. — peruensis Hsck. (38 b) is a similar form from the Upper Amazon, from Peru. 



The t^round-colour is light red-brown in both sexes, with transparent longitudinal band at the base of the hindwing. 



The yellow oblique band of the forewing is still broader, not transparent, with small dark spots at the end of 



espriella. the cell. The dark spot in the ceU is very faint. — espriella Hew., from Ecuador, is a more strongly coloured 



tarapotis. form with dark apex to the forewing, without the transparent longitudinal band in the hindwing. — As tarapotis 



form. nov. I designate a form from the Lower Amazon, in which the yellow oblique band is almost entirely absent 



except for an indistinct spot at the costal margin. The colour, as in espriella, is vivid red-brown to the apex. 



radiosa. In C. radiosa Hsch., from eastern Ecuador, the apical half of the forewing is blackish, with radiate, 



vellow macular band. The dark spot at the base is elongate-pointed. The hindwing has a macular median band 

 and dentate, dark distal margin. 



cayana. C. cayana Salv. (38 b), from Guiana, has in the blackish apex a peculiarly formed, yellow oblique band 



with approximated spot at the inner angle. The spot in the cell is absent. The hindwing has a broad median 

 band and both wings whitish marginal dots. 



jolaia. C. jolaia Hew. (38 b), from Colombia, resembles Napeogenes stella. In the disc of the forewing there 



are a number of yellow spots, and in the distal margin of both wings large, yellow marginal dots; in the cell of 

 the forewing a biack, rounded spot and at the apex of the hindwing the commencement of a median band. — 

 conveniens. In ab. conveniens Hsch. the spots in the forewing are united into an angular band at the end of the cell. 



doto. C. doto Hhn. (38 b), from the Lower Amazon, is a very aberrant species with diaphanous wings; the 



margins and the discocellular of the forewing are margined with dark. The median of the forewing and a broad 

 submarginal band on the hindwing are yellow-brown. 



24. Genus: Hyposcada Godm. & Salv. 



It is not possible to differentiate this genus very sharply from Leucoihyris, as there is a gradual transition 

 in the characters. Thus a number of forms which approximate to one another, as ilerdina and ina, have been 

 placed in two different genera. I therefore only leave in this genus the forms which are allied to the typical species 

 and place the others with the similar forms of Lencothyris. 



Hyposcada is distinguishable by the long, thin antennae and the short cell of the hindwing. Costal and 

 subcostal run at a distance from one another. Upper and middle discocellulars of the hindwing are short and 

 almost equal in length. They are medium-sized butterflies of mostly red-brown ground-colour, which recall 

 many species of Ceratinia. They occur especially in north-west South America, some also in Central America 

 and are for the most part not common. 



adelphina. H. adelphina Bates (38 c), from Colombia and Panama, has a broad, red-brown base to the forewing 



and red-brown hindwing with broad black distal margin. The rest of the forewing is black with a large number 

 of white spots. Also at the apex of the hindwing are placed 2 — 3 white dots. The under surface is similarly 



virginiana. marked to the upper. — virginiana Hew., from Mexico and northern Central America, has narrower wings. The 

 red-brown colour of the forewing reaches nearly to the end of the cell and the two white spots there are small 

 and roundish. Especially worthy of note is the under surface, which is brown also in the whole apex of the fore- 

 evanides. wing. — In a third form, from Costa Rica, which I call evanides form, nov., the ground-colour of the forewing 

 is black-brown except for two red-brown streaks at the base, and the same beneath. The wings are narrow as 

 in virginiana, the white spots as in adelphina. 



consobrina. H. consobfina Godm. <& Salv. (38 c) is similar to the preceding, with larger, yellowish spots, without 



the two spots in the end of the cell of the forewing. It flies in eastern Ecuador, at the foot of the Andes. 



anchiala. H. anchiala Hew., from the Upper Amazon to Peru and Ecuador, has smaller white spots in the black 



apical half and a black streak at the median of the forewing, as well as black margins to the hindwing and 

 a broad, spot-like median band in the disc.
