218 Mr. A. G. Butler on a new Species of Tiger-Moth. 



XXVI. — Description of a new Species of Tiger-Moth in the pos- 

 session of Mr. T. fV. Wood. By Arthur G. Butler, F.Z.S. 

 [Plate IV. figs. 1-3.] 



The species of Tiger-Moth described in the present paper is the 

 most beautiful that I have yet seen ; it appears to be quite new, 

 and to belong to the gew\x%Maz(Eras, characterized by Mr. Walker 

 in his ' Catalogue of the Lepidoptera Hcterocera in the British 

 Museum;' the Eucharia sacrifica of Hiibner's 'Zutrage exotis- 

 cher Schmetterlinge ' seems also to belong to tliis genus: all 

 the species are South American. This group will now stand as 

 follows : — 



Genus Maz^eras, Walker 



(Cat. Lep. Het. Brit. Mus. pt. iii. p. 632, genus 14.) 



" Corpus longum, validum, cylindricum : proboscis corporis dimidio 

 brevior : palpi ascendentes, longiusculi ; articuhis secundus arcuatus, 

 primo multo longior ; tertius conicus, minimus: anteimaj mediocriter 

 pectiuatffi, corporis dimidio non longiores : abdomen alas posticas 

 longe superans : pedes validi, longiusculi ; tibiae })ostica2 calcaribus 

 quatuor lougis. Alee angustae, sat longai." — Lcp Het. 



Sp. 1. Mazceras conferta, Walker, p. 633. 



*' Saturate rufa ; palpi apice nigri ; ante'imse nigra? ; thorax ocello 

 discali maculisque quatuor nigris : abdomen luteum, e macubs 

 nigris trivittatum ; tibiae tarsique nigree ; alae anticae fuscae ma- 

 cubs rufis strigisque transversis testaceis." — Le^j. Het.

Sp. 2. {Eucharia) sacrifica, Hiibner 

 (Zutrage exot. Schmett. figs. 473, 474 (1806).) 



Olivaceo-fusca ; thorax collo albicante ; abdomen supra viridescente 

 fasciatvim, punctis lateralibus albis, ano rufesceute : alae anticae 

 roseo-albo fasciatae, subtus ad marginem albo rubroque maculatae : 

 posticfe punctis marginalibus lunulatis maculisque quiuque sub- 

 apicalibus albidis ; macubs submarginalibus rubris.

Hab. Ipaunema (Brazil). 



The genus Eucharia is characterized by Hiibner in his ' Ver- 

 zeichniss,^ p. 181. n. 1865-1867 (1816) ; he does not, however, 

 include his sacrifica, which certainly is not congeneric with 

 those species wbich he does include.
