tiger - moth is found

Genus MiENAS Hiibner 
Only one species of this rather extensive genus, which is 
represented in South America by five species and by a con¬ 
siderable number in Africa and the Indo-Malayan region, occurs 
in North America. 
(1) Maenas vestalis Packard, Plate XVI, Fig. 5,3. (The 
Vestal Tiger-Moth.) 
This insect, which closely resembles Estigmene congrua, 
figured on the same plate, may be distinguished from the latter 
not only by structural peculiarities, but unfailingly by the 
ordinary observer, by the presence of the two black spots on 
the hind wings, as shown in our illustration. 
Genus DXACRISIA Hubner 
This large genus, which includes over one hundred and 
twenty-five species, according to the arrangement given in 
Hampson’s Catalogue, not reckoning the species referred to 
the genus Isia , which he also places here, is represented in 
our fauna by four insects, of which we give illustrations. 
(1) Diacrisia virginica Fabricius, Plate XVI Fig. 7, 
(The Virginian Tiger-moth.) 
The form figured on our plate is the slight variety named 
fumosa by Strecker. in which the fore wings are a little dusky 
at their tips as if they had been flying about in the smoke of 
the furnaces at Reading or Pittsburgh. Ordinarily the species
