218 Mr. A.G. Butler on a new Species of Tiger-Moth. 
XX VI.—Description of a new Species of Tiger-Moth in the pos- 
session of Mr. T. W. Wood. By Antuur G. Burien, F.Z8. 
[Plate IV. figs. 1-3.] 
Tue 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 genus Mazeras, “characterized by Mr. Walker 
in his ‘ Catalogue of the Lepidoptera Heterocera in the British 
Museum ;’ the Eucharia sacrifica of Hiibner’s ‘Zutrage exotis- 
cher Schmetterlinge’ seems also to belong to this genus: all 
the species are South American. This group will now stand as 
follows :— 
Genus Maza#ras, Walker 
(Cat. Lep. Het. Brit. Mus. pt. ui. p. 632, genus 14.) 
“ Corpus longum, validum, cylindricum : proboscis corporis dimidio 
brevior : palpi ascendentes, longiusculi; articulus secundus arcuatus, 
primo multo longior ; tertius conicus, minimus: antennze mediocriter 
pectinatee, corporis dimidio non longiores : abdomen alas posticas 
longe superans: pedes validi, longiusculi; tibize postice calcaribus 
quatuor longis. Ale anguste, sat longe.’—Lep. Het. 
Sp. 1. Mazeras conferta, Walker, p. 633. 
‘“‘Saturate rufa; palpi apice nigri; antenne nigree ; thorax ocello 
discali maculisque quatuor nigris: abdomen luteum, e maculis 
nigris trivittatum ; tibize tarsique nigre ; ale anticee fuscz ma- 
culis rufis strigisque transversis testaceis.’—Lep. Het.

Sp. 2. (Eucharia) sacrifica, Hiibner 
(Zutrage exot. Schmett. figs. 473, 474 (1806).) 
Olivaceo-fusca ; thorax collo albicante ; abdomen supra viridescente 
fasciatum, punctis lateralibus albis, ano rufescente: alee anticee 
roseo-albo fasciatee, subtus ad marginem albo rubroque maculatee : 
posticee punctis marginalibus lunulatis maculisque quingne sub- 
apicalibus albidis; maculis submarginalibus rubris. 
Exp. alar. unc. 2. 
Hab. Tpaunema (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 which he does include.
