HETEROSAIS. By E. Haensch. — Addenda. — Alphabetical List. 165 



H. lydia Weym., from Ecuador, has a broad, yellow- brown costal margin to the forewing, in which lydia. 

 it recalls Ptewnymia apideia (40 a) and Hymenitis enigma (41 f). The pattern is as in ochretis, with smaller, 

 indistinct, yellowish patches. 



H. quinta Stgr.,-hom. the Cauea Valley in Colombia, is one of the Ithomiids which are entirely Avith- quinia. 

 out markings on the wings and recalls the very similar Episcada faradoxa, with which it also agrees in 

 size, and also Velamysfa anomala, Napeogenes hypsaea, Ithomia dimidiata and other forms with unmarked, 

 coloiuless or yellowish wings, quinta is distinguishable from the similar species of other genera by the large, 

 non-angled lower discocellular of the hindwing, which almost alone closes the cell. 



35. Genus: Heterosais Godm. d- Sa,h. 



In this last genus of the Ithomiids the cell of the hindwing in the ^^ is open, the middle disco- 

 cellular and upper radial being absent. The subcostal is strongly developed and curved in the middle. The 

 lower discocellular is directed proximad and forms with the lower radial an acute angle, from the point of 

 which a vein runs into the open cell. In the $ the cell is closed, as the lower discocellular is angled and 

 reaches to the upper. Middle discocellular and upper radial are absent here also. 



The species of this genus are not numerous. They occur mostly in the north-west of South America 

 and the adjoining districts of Central America. They are mostly inconspicuous forms of medium size, which 

 are found with the similar species of other genera in the undergrowth of the primeval forests. ■ ^ (^ 



H. nephele Bates, from the Upper Amazon, and gedera Hew. (41 g), from eastern Ecuador and Col- nephele. 

 ombia, are two very similar forms. Both have vitreous wings with bluish sheen and black-brown margins ^ 

 and half-band on the forewing in addition to a white spot at the end of the cell and 2 whitish patches in 

 the apex of the forewing and on its underside 2 more white dots in the distal margin; in the distal margin 

 of the hindw'ng a row of dark edged white dots. — edessa Hew. (41 g) is a similar form from southern edessa. 

 Brazil ■«ith smaller white spot at the end of the cell of the forewing, .yellow-brown margins on the under 

 surface and light base to the hindwing. 



H. pallidula Hsch., from western Ecuador, has yellowish wings with yellow-brown subcostal and pallidula. 

 a broad stripe on the median of the forewing. The other margins are dark brown, only the distal margin 

 of the hindwing is partly variegated Avith yellow-brown. At the end of the cell of the forewing and the distal 

 margins there are yellowish dots. In the $ only the subcostal of the forewing is yellow-brown, the other 

 margins are brown. 



H. giulia Hew. (41 g), from Colombia and Venezuela, has a similar (J to pallidula, with broad yellow- giulia. 

 brown subcostal vein and stronger yellowish dots. The $ is quite similar, but more brightly marked, with 

 broader margins, yellow oblique band on the forewing and large yellowish dots at the distal margin. 



H. cadra Godm. & Salv., from Panama, is said to be similar to nephele and giulia. The wings are cadra. 

 colourless. The dark half-band of the forewing is proximally broader, the band beside it is white, the inner 

 margin yellow-brown.

 Napeogenes domiduca Hew. very closely approaches some Leucothyris, such as LeAic. cyrene; further clomiduca. 

 details are given under the latter, p. 148; from Bolivia.
