134 HETEEOSCADA; NAPEOGENES. Bij B. Haensch. 



found rather commonly among immense trees, together with tlie very similar Nafeogenes glycera and lycora, 

 Itlwmia linda, Hypoleria coenina, Threnodes coeno'ides^ etc. 



eupompe. The last species of this extensive genus, C. eupompe Geyer (= phlysto Fldr.) (35 d), from South Brazil, 



stands quite isolated, much more recalling certain species of the genera Napeogenes, lihomia and Pteronymia. 

 The wings are short, transparent yellowish, with black margins and a half-band across the end of the cell of 

 the forewing; on the under surface with rows of red-brown spots and whitish double spots. Antenna black, 

 collar red-brown. — Larva according to W. Muller rather transparent, above grey-green, head yellow, later 

 black. Pupa transparent green, with shiny gold lines and black spots. 



16. Genus: Heteroscada Schatz. 



This genus contains only 2 small, j^ellowish forms, which occur in Brazil. The middle discocellular of 

 the hindwing is weakly curved proximally, the upper one in the (^ is long. 



gazoria. H. gazoria Godt. (= yanina Hew.) (36 d). This pretty little species is very similar to Pteronymia hemi- 



xanthe (40 d). The collar is red-brown, the abdomen beneath yellow. The wings are dusted with yellow 

 to beyond the end of the cell and have dark margins. 



fenella. The somewhat larger H. fenella Hew. has broader borders, a broader half-band across the end of the 



cell of the forewing and a red-yellow spot at the base. It closely resembles Napeogenes xantlione. — Both 

 species fly in Central Brazil. 



17. Genus: Napeogeiies Bates. 



In this extensive genus there are many forms whose pattern and colouring recur in certain Ithomias, 

 so that they can only be recognized by the neuration. All the Napeoge^ies may be distinguished from the 

 similar species of other genera by the non-angled discocellular, the long cell and the apparently 5-branched 

 median in the hindwing. — The species are scattered over the whole Neotropical region, mostly mixed with 

 the corresponding species of other genera, but are usually rare, whilst the more vigorous Ithomias are met with 

 in large numbers. 



peridia. N. peridia Heiv. (35 d), from Colombia, has similar markings to CaUithomia tridactyla and Hirsuiis 



hemime- Jigcalesina ; the hindwing is. however, distinguished by large yellow distal-marginal dots. — In hemimelaena 



Godni. (& Salv., from Panama, the yellow spots at the end of the cell of the forewing are united into one large 



one, as in iquitensis (35 d). The yellow spots at the apex and distal margin of the hindwing on the contrary 



are very small and the apical half consequently much more strongly coloured with black. 



iquitensis. N. iquitensis Stgr. (35 d), from the Upper Amazon, has in the black apical half of the forewing a broad, 



curved, yellow band; in the red-brown basal half 2 black spots and on the red-brown hindwing a black mac- 

 ular band and dentate distal margin. 



umara. N. amara Godm. (35 d), from Central America, is smaller than feridia and has in the apical part of 



the foreAving fewer, but larger, yellow spots, and at the base a red-brown spot. The marginal dots are smaller 

 and Avhite. At the apex of the hindwing are placed 2 indistinct j^ellowish spots. — In the somewhat larger^ 



tolosa. tolosa Heiv. (35 e) the ground-colour of the hindwing and the base of the forewing are lighter yellow-brown. The 

 yellow spots of the forewing are larger, the distal border of the hindwing narrower, tolosa inhabits Mexico 

 and northern Central America. 



olyrina. The interesting and rare N. olyrina Hsch. (35 e), from Bolivia, recalls Ceratinia excelsa and Olyras mon- 



tagui. The black forewing has large whitish vitreous spots, the red-brown hindwing bears in addition to the 

 broad, dark marginal band a hyaline oblique band in the apical half, as in excelsa. 



larina. N. larina Hew. (35 e), from eastern Colombia, has white spots on the forewing; of the marginal spots 



those in the apex are larger; the base of the forewing is red-brown. In the disc of the hindwing are placed 

 3 isolated black spots. Itlwmia candescens is very similar. 



aethra. N. aethra Hew. (35 e), from the upper Napo in Ecuador, has larger, band-like, yellow spots in the disc 



of the forewing and indistinct j^ellow marginal dots. The hindwing is dark-margined, with 4 black spots in 

 the disc. 



duessa. N. duessa Hew. (35 e) may be recognised by the chestnut-brown ground-colour and the two black half- 



bands at the apex of the hindwing. The forewing has a yellow median spot with black dot and a dark brown 

 base. This peculiar species fhes on the Upper Amazon in Peru and Ecuador. 



quadrilis. In N. quadrilis Hsch., from the Upper Napo, the ground-colour is yellow-brown and the yellow median 



spot of the forewing is prolonged, forming an oblique band. In the dark-margined hindwing a large 

 black-brown spot is placed at the inner angle.
