also in the cell of the forewing, otherwise thej' resemble platea; — the same small spots occur also in plintho- pUnthdba- 

 baphis Stick.; but there the red band of the hindwing is also expanded almost to the border; Peru. ^ ■ 



N. olinda Bat. (139 b). Quite similar to lisimon, but above there is no red at all, and the white oblique olinda. 

 stripe beginning narrowly from the inner margin of the hindwing, grows more and more narrow and dim, so 

 that it is obliterated near the centre of the hindwing. The $ which has already the long wings of mantus (140 e), 

 exhibits a broader and above less darkened oblique band. Central America, rare. — • The Colombian form, 

 fulminans Bat. (139 b), with a considerably broader median band, is much more common. fulminans. 



N. nealces Hew. (140 d). A very rare butterfly of which I have seen but few specimens. The forewings nealces. 

 similar to those of baeotia (140 d), in the hindwings, however, the whole inner-marginal part is orange. Beneath 

 forewings likewise greatly resemble those of baeotia, the hindwings, however, are in the ^ quite light-yellow^ 

 with 5 brown marginal spots in front of which a narrow, small, curved brown band winds from the apex towards 

 the anal angle w'hich, however, it does not reach. $ with a broad, pale-yellow median band. Known to me 

 only from Cayenne, from where also the figured specimen. 



N. baeotia Hew. (140 d as baeotica) looks almost like a small olinda. The light median band is some- baeotia. 

 times darkened by grey, varies somewhat in width and its upper end is obtuse in the $. The $ mostly has also 

 whitish fringes of the hindwings. Guiana, Amazon. — tninuta Drc. (142 h) is a form with a much brcader and >ni»"f". ~ t-i^'-h 

 brightlj' white median band, a broad white border of the hindwing in the $ and an almost snow-white, scarcely - '"""° 

 black-spotted under surface of it. Before me from Matto Grosso, but also from the Chiriqui. At some places 

 very common. 



N. mantus Cr. (140 e). Larger than baeotia, similarly marked, but with a reflecting light-blue costal mantu.9. 

 area of the forewing and a similar distal half of the wings; the surroundings of the white band black. — ab. 

 thryptica Stick. (140 e) has a small rusty-yellow semi-band proceeding from the inner margin of the hindwing. thrypiica. 

 From Guiana and Venezuela to Brazil. Not common. 



N. omois Hew. (139 e). A small butterfly from the Amazon, forewing dark brown with a white, large omois. 

 triangle placed on the inner margin ; hindwing white with a black-spotted marginal band. In front of the marginal 

 spots runs a distinctly though irregularly defined, golden-yellow band. Rare. 



N. caricae L. (139 a). Dark brown, with a broad w^hite band beginning taperingly behind the cell caricae. 

 of the forewing and terminating broadly at the inner margin of the hindwing. Costal part of the forewing with 

 orange-red spots, in front of the border of both wings an orange-yellow band, behind it, in the brown shade 

 of the border, whitish bows. Abdomen white. According to the habitat and even to the season, the distribution 

 of the red-yellow and black varies considerably, as well as the size which varies between 20 and 36 mm in my 

 specimens from Cayenne and Colombia, ab. carmentis Stick, has the white increased, being continued lacini- carmeniis. 

 formly at the upper end of the median band; — in carissima Stick, the marginal band of the hindwing is without carissima. 

 the whitish bow-streaks. Guiana and Colombia. Here and there very common. 



N. acHerois Bsd. (139 a, only the (J). Costal and distal parts of the hindwings blackish-brown, with acherois. 

 broad orange-red fillings. Behind the upper end of the white median band a white subapical spot. — South 

 Brazilian specimens exhibit a narrower golden-yellow border of the hindwing; the sms^U white subapical spot 

 may be stunted to traces, but also so enlarged that it is confluent with the median band. These forms ought 

 not to be denominated, but the South Brazilians were separated as erymanthus 316)1. (139 a, also the figwce erymanthus. 

 denoted as ackerois-"^). Guiana to South Brazil; common. 



N. balbinus Stgr. (139 a). Typical balbinus differ from our specimen originating from Chuchurras balbinus. 

 (Rio Polacaza) by a still broader red band of the hindwing, which, however, has no black dots and neither passes 

 over to the forewing. The typical balbinus come from Rio San Juan in Colombia; only the ,^(^ are known. 



N. haematostictum G. d; S. (= hasmostaticum Stick.) (139 a) from Panama and the adjoining part ''"""a'os^ic- 

 of Colombia resembles a 9 of acherois, but it has more white which is slightly darkened by yellowish, and only '""' 



in the marginal band of the hindwing there is yet an orange-yellow filling. Rarer. 



N. onaeum Hew. (= blakei Weeks) (139b). White with a dark-brown marginal band; cellular part onacum. 

 of the costal stripe with red-yellow spots, before the marginal brown in the anal part of both wings there is 

 likewise red-yellow. Central America from Honduras to Panama, Colombia and Venezuela; apparently not 

 common. 



N. chione Bat. (= stilopteris Btlr.) (139f). Snow-white, with black margins, without any red-yellow, chione. 

 the white discal part irregularly defined. In the black marginal band white arcuate lines. Amazon to South 

 Brazil . 



N. menalcus. Of this species there exist 8 forms. In order to preserve the denominations, we might 

 make the following differentiations: cachrusi^. (= damon Hbn .) is a large form with a pale-yellow ground-colour, cachrm. 

 a copiously marked, proximally irregularly defined, jet-black marginal band. This form being especially common 

 in Colombia, but occurring also in the Amazon District and Guiana, is represented by our Q-figure; the $ of 

 it is figured 142 h. — The animal figured 139 f as cachrus-'^ already forms a transition to the typical form of 

 menalcus (= onoba Hew.) a couple of which is figured 142 h, being distinguished by a proximally smoothly mowlcus.
