HYPOLERIA. By R. Haensch. 159 



31. Genus: Hypoleria Godm. & Salv. 



The oo i^'X'^" be recognised by the elongate oval scent-spot at the costal margin of the hinchving 

 and by the non-angled lower discocellular, which forms an acute angle with the median, is curved inwards 

 and mostly aborted at the lower radial. In the $ costal and subcostal are coincident to the middle, other- 

 wise the neuration is as in the <^. 



The forms which belong here have mostly a rounded apex to the forewing and roundish hindwing. 

 In addition to those with colourless wings there are also gay-coloured species, especially a group with red- 

 bro'wn band in the apex of the forewing, such as may be found in Leucothyi-is and also in Pseudoscada. 

 Some forms also resemble the latter genus in other respects, so that it is often not easy to differentiate 

 9$ of the two genera. 



Of this not very extensive genus also the region of the eastern Andes produces the largest number 

 of species, yet some forms also occur as far as South Brazil and in Central America. 



H. vanilia H.-Schdff. (40 g), from Colombia, is very similar to the smaller Pseudoscada lavinia (41 b). vanilia. 

 The forewing is shaded with dark, with black margins and 2 oblique bands at the end of the cell and 

 before the apex. The interspace is divided bj^ the dark-marked veins into a number of whitish spots. The 

 hind\s"iDg is rust-bro'«Ti, with broad border at the apex; in the $ with yellow-brown, proximally dark 

 brown costal margin, in the (J transparent at the costal margin. — libera Godm. <f Salv. is a local form of libera. 

 the preceding from Central America (Panama, Costa Ptica). It has more strongly marked dark patches and 

 brighter red-brown colour on the hindwing. • — futnosa Godm. & Salv., from Panama, is a form of the fumosa. 

 preceding with darkened apical spots and triangular spot in the cell of the forewing. 



H. hyalinus F., from Brazil, is a doubtful form and unknown to me in nature. According to hyalinus. 

 Butler it is a form similar to vanilia, with transparent forewing and black margins, and also a macular 

 band in the apex. Hindwing red-brown with narrow black distal border. 



H. fausta Stgr., from the Upper Amazon, is a smaller species with brownish hindwing and base of fausta. 

 the forewmg. Across the end of the cell of the forewing is placed a broad dark half-band, which is 

 divided at the median veins. In the end of the cell and at the distal margin there are whitish patches. 



H. alema Hew., from Colombia, has according to Hewitson's figure transparent yellowish wings with edema. 

 dark margins and narrow band across the end of the cell of the forewing; before the distal margin of the 

 latter with whitish dots. On the under surface the margins are reddish, except the blackish costal margin 

 of the hindwing. 



H. ina Hew., from Ecuador, is a similar species with a row of whitish submarginal dots at the ina. 

 distal margin of the forewing and without markings at the end of the cell. The inner margin of the hind- 

 wing is broadly reddish yellow-brown. In this the species recalls Na-peo^enes apulia (35 f). 



H. ocalea Dbl. & Hew. (41 g), from Venezuela, Trinidad and Colombia, has light yellow-brown wings ocalea. 

 with dark margins and an oblique band across the end of the cell of the forewing, which is continued 

 beyond the 3""'' median vein. The median of the forewing and the veins of the hindwing are yellow-brown. 

 The macular band of the forewing is yellowish. — The white, longitudinally ribbed eggs are according to 

 GupPY attached singly about 2 ft. above the ground. The larvae hatched in 5 days. They are trans- 

 parent, gi-een, with whitish head and take 9 days to feed up. 



H. gephira Hew. (41 g), from Colombia and the adjoining parts of Central America, is a similar gepliim. 

 species with broader margins; with whitish spots in the apex of the forewing and at the distal margin of 

 the hindwing. Moreover the veins in the distal half of both wings are black. 



The following forms have a broad yellow-red subapical band in the forewing and hence resemble 

 the similarly marked forms of Leucothyris and Na'peogenes, and also certain Erycinids. 



H. chrysodonia Bates, from the Upper Amazon, is almost the same size as aureliana Bates (= trom- chrysodonia. 



(XliyBiKXilQ. . 



bona Srka.) (41 a), from the same district. In the former the yellow-red colour is proximally semitrans- 

 parent. The 2'"' and 3''' median veins of the forewing are only narrowly margined with dark. In aureliana 

 the yeUow-red band is broader and the extremity of the median and also its branches are broadly mar- 

 gined with dark brown, so that between the veins only 2 smaller vitreous spots remain. Moreover, 

 the base of both wings is also shaded with dark. The antennae are black in both species, whilst in 

 karschi Hsch., which is otherwise very similar to chrysodonia and flies at the Upper Napo in Ecuador, they karscM. 

 have a yellow-brown club. In karschi the yellow-red subapical band only reaches the 3"' median vein. — 

 Another similar form is cidonia Hew., from Colombia. In this the antennae are black and between the cidonia. 

 median veins there are 2 larger colourless vitreous patches. The hindwing has a yellowish submarginal band. 



H. orolina Hew. (40 g), occurring at the Upper Amazon as far as the foot of the Andes in Peru and orolina. 

 Ecuador, is a smaller, delicate species with almost colourless wings and yellow-brown subapical band. — In 

 oculata H-ich., from the Upper Napo, which is the same size, there is another rounded vitreous spot be- oculata. 

 tween the end of the cell and the band, which is narrower. — ■ A similarly marked form, but larger 

 than oculata, from Ucayali, which I call sedusa for7n. nov., has a white patch at the end of the cell of the sedusa.
