MAZAERAS; ELY ST US. By Dr. A. Seitz. 
385 
A. paranomon Dyar (53 h) discovered by Roberto Mueller near Zacualpan (Mexico), resembles 
more certain Pachydota, Mazaeras etc. Forewings dark brown, with a broad, blackish transverse band before 
and behind the middle and at the margin, as well as a dark, costal demi-band above the cell-end. The inner- 
marginal base, hindwing and abdomen pink, hinclwing with a dark distal band. Rare. 
A. trujillaria Dgn. (53 i) from Peru resembles Amastus occurring there. Forewing dirty yellowish- 
brown, watered dark, and with a brown marginal band proximally undulately bordered. Hindwing lighter, 
only in the apical part dark. A large species. 
A. helops. By this name the members of entirely different South American genera are presumably 
confounded even to this very day. This is easily possible, since on the one hand two forms (those with more 
unicoToro'usly dark forewings and those with spotted yellow forewings), although they are easily discernible 
and are taken to be subspecies *), .occur beside each other in certain habitats, on the other hand by reason of 
the entirely deviating larvae yielding the helops. Moreover, they are probably confounded with similar Mazaeras 
or Elysius (e. g. cingulata, 53 h). — helops Cr. (= fervidus Wkr.) (53 h) has the dark forewings intermixed with 
honey-coloured spots of an irregular shape, and the orange-yellow abdomen is banded black; its base, as well 
as the hindwings, tinged pink. Mexico, Central and South America, here particularly in the north and east. - 
In the south and west, but to the north as far as Costa Rica, we find the form with dark forewings being 
little or not at all spotted yellow, megapyrrha WJcr. (= chrysogaster Wkr., impunctus Get.) (53 h). — The 
larva of the typical helops, which is lying before me from Mexico owing to the kindness of Prof. Dr. Draudt, 
is reddish greyish-brown, covered with a dense, short, velvety black, felt-like fur, the head reddish yellowish- 
brown, lustrous. In contrast with this, it is quite differently figured, greyish-brown, also the head, covered 
with thin tufts of long white hair; across the dorsum extends a broad white band bordered with dark and longi¬ 
tudinally traversed by three rows of green dots. (This latter larva will presumably much rather yield Mazaeras 
conferta). 
A. klagesi Rothsch. (53 i) has unicolorously dark brown wings; the head, thorax, and apex of abdomen 
are red, the abdomen otherwise above black. According to Hampsox, it belongs in the genus Tessellarctia. From 
Fonte Boa (Amazon). 
66. Gattung’: Mazaeras Wkr. 
Large butterflies with a glaringly coloured body being uncommonly clumsy in the female, with a fully 
developed proboscis, the fur-like haired palpi being bent up and projecting somewhat, and in both sexes with 
doubly combed, rather long antennae. On the forewing the 1st and 2nd subcostal veins branch off before the 
cell-end, the latter anastomoses with the pedicle of the 4th and 5th. forming a long areola; the discocellulars 
on both wings rather long, the transverse vein slightly bent in. Only 3 species are known, being rather similar 
to the palearctic Arctia in the structure; but whilst the stout Arctia-Q 9> as for instance those of A. hebe, are 
not well adapted for flying and, in depositing the eggs, run mostly only in a whizzing way along on the soil, 
the $$ of Mazaeras easily rise to a considerable height and even fly across broad rivers. Their chief range is 
in South Brazil, where they come to the lantern rather late in the evening. As to the larva, comp, what has 
been said in Ammalo helops. 
M. conferta Wkr. (53 h) is similarly coloured like the very variable A. helops, but of a much stouter 
structure, with shorter and feebler antennae. Hindwings purple, with a more pointed apex. Abdomen more 
thickly spotted black. A considerably smaller than the $$. Particularly on the eastern coast of South Brazil. 
M. melanopyga Wkr. (53 g). Dark wood-coloured, forewing with a light dot at the cell-end, before 
the marginal area a small, undulate, light band. Hindwing in the proximal part thinly scaled, at the base reddish. 
Dorsum of abdomen as far as the middle of the abdomen pink, terminal half of abdomen, venter and sides of 
abdomen black. Eastern coast of Brazil, from Pernambuco to Sa. Catharina; the figured specimen from Santos. 
M. jatieira Sch.s. (53 i). Smaller, forewings more striated. Hindwings of a lighter greyish-brown, 
abdomen yolk-coloured, with black dorsal and lateral spots. South Brazil. 
67. Genus: Elysius Wkr. 
This genus, containing many species, forms a great contribution to the neotropical Arctiids. In tropical 
South America it proceeds relatively far to the south and in Mexico it is represented vet with rather many species, 
but it does not reach the United States any more. They are of a compact structure, the head is stout, woolly 
haired, with a strong proboscis; palpi densely haired with a short basal joint, long middle joint and stunted
