XENANDRA. By Dr. A. Seitz. 



ccrcopes. L. cercopes Hew. (131 g). This pecnlicarly coloured butterfly is without the red subbasal dots as well 



as the oblique band, so that only the orange-yellow margin or the hindwing remains extending at the apex 

 into the forewing, at the anal angle of which it forms a point showing towards the cell-end. Peru; all the spe- 



andania. cimens I examined, also the figured one, originated from Pozuzo. — andania Heic. (131 g) looks quite differently, 

 but it is connected with cercopes by a number of transitions. The yellow margin of the hind-wings is often (not 

 always and mostly only above) smoothly cut off against the ground-colour, and the yellow ray showing from 

 the anal angle of the forewing towards the costa extends as far as to the subcostal or even reaches the costa, 

 from Bolivia and Peru. The figured specimen originates from Salampioni in Bolivia, 800 m. Specimens from 

 lower districts mostly are somewhat larger, 



craiia. L. cratia Hetv. (131 g). Immediately recognizable bj^ the broad purple abdominal parts leaving free 



onlj- a narrow black dorsal stripe on the 2. to 5. ring. Wings jet-black; the foiewings with an orange-yeilow 

 oblique band, the hindwings with a narrow, incomplete golden-yellow marginal band. Colombia and Venezuela; 

 not rare. 



hodia. L. hodia Btlr. From Valdivia in Colombia, has remained unknown to me. Cf. Additions. 



pheredus. L, phereclus Cr. (— seieukia Stick.) (131 g, h). Exteriorly somewhat similar to Panara pherechis L. 



above blackish-brown with an orange oblique band, but immediately discernible by the under surface, where 

 the hindwings exhibit a hemochrome basal spot and white veins, whereas in Panara they are velvetj' black, 

 sornetimes \7ith a blue reflection. South Brazil, Guiana, Peru; in the range of Panara where it flies in the 

 company of other equally coloured Erycinidae, such as the $2 of Mest?ie sagaris, some $2 of Aricoris etc., 

 but also with numerous patented Heierocera, such as Mirradaeinon iirsula Stall and others. — Rare. 



marathon. L. marathon Fldr. (= ctesiphon Fldr.) (131 h). I figure the type from the Coll. Feldbk which Lord 



Rothschild had the kindness to lend me. In this $ the band of the forewing is seen slightly curved proxi- 



steiiotaema. mally. Colombia to Peru. — In stenotaeaia Rob. (131 h) from Pozuzo the band runs rather straight and is 



assimulata. narrow, in assimulata Stick. (131 h), the most common form from Colombia frequently found in the so-called 



,, Bogota-Collections", it is even somewhat proximaJly concave and shortened. — All the forms of marathon 



have magnificent purple sides of the abdomen, whereby they show an alliance with cratia Hew. 



barca. L. barca Heu\ (131 ii). This peculiar species from Pernambuco shoivs a: first sight that is has bor- 



rowed the exterior of an Actiiiote together with which it must consequentlj'' fly. There is only a secondary 

 resemblance wiih a Stalacktis susanna (which, likewise copies Actinote). The model for Lymnas barca and Sta- 

 lachtis susnnna is probably an Actinote of the leptogramma- or kypsipetes-groiir). 



Ihyatira. L. thyatira Hew. (= phlegontis Stick.) (131 h). This butterfly is likewise subject to mimicry. It imi- 



tates Eueides alipkera and, because in mimicry only the total appearance, brrt not the repetition of finer de- 

 tails in the marking is of a biological value, it is so inconstant that I have never yet beheld two equal spe- 

 cimens. Only larger series of the different habitats would permit ,, subspecies" to be established; but the butter- 

 Vfly is so rare that for the present the collections mostly contain only single specimens from the different ha- 

 bitats. The variation refers to the ground-colour, size, length of the black T&ys, width of the margins and their 

 delimitation. The figured specimen originates from Cuyaba and differs just as much from that inHEAViTSONS. 

 collec.ion from the Amazon, as from the one figured by Stichel in Wytsm^ns Genera In-sectorixm. Brazil, 

 Bolii^ia, Colombia, Guiana; dispersed and rare. 



31. Genus: Xeiiaudra Fldr. 



Is closely allied to the preceding genus, i. e. to its mimetic grou^) of barca-tkyatira. M\ the species 

 belonging hereto are rare. The butterflies have still longer forewmgs than the Lymnas, from which they are 

 otherwise distinguished only by the verjr stout (in the 2) and quite short (in the ^) abdomen. Ovdng to the 

 narrow wings the flight of the $$ is almost whizzing, quite similar to that of the copied Heierocera (Cyllc- 

 podinae). May be that some more species having hitherto been treated as Lymnas will prove to be better in- 

 cluded in Xenandra. 



X. agria Hew. (131 h, misprinted in argia). The $ belonging to this $ which I only know from 

 Hewitsoiq is .mknown to me. The 2 is surely mimetic copying some of the South Brazilian Pericopiins or 

 other Ai'ctiids which partly fly in day-time or are often chased up. All the 4 wings \vith orange-yellow mar- 

 ginal spots, the forewings with a broad, golden-yellow oblique band sending below the costa a ray towards 

 the base, the hindwings with a yellow cell. Very rare, in South Brazil; v. Boei«!NINGHA.tjsen captured the 

 animal only once in more than 30 years, near Rio de Janeu'o; he presumed it to be the $ of Lymnas volusia 

 which is just as incorrect as Stichels presumption that it belongs as $ to Xen. keliodes.
