SYNOPSES OF BUTTERFLIES. 
EUREMA, 22. 
General body form and habitus asin Vanessa. Wings strong ; pri- 
maries triangular with rectangular apices, slightly produced at the 5th 
vein and subsinuate beneath to hind angle which is evident. Secondaries 
tailed, the interior half of wing decidedly longer than the outer. 
One species only is usually included in our fauna. 
E. lethe, Fab. Ent. Syst. III, 1. p. 80 (Papilio); demonica Hb., Sam. Ex. 
Schimett. II, f. 1, 2, (Hypanartia). 
Above pale fulvous, darker at interior half of secondaries, primaries 
with apical third, outer margin and an oblique dash from near base of 
costa to hind angle, black ; apical space with two oblique and interrup- 
ted fulvous bands. Secondaries with an elongate patch from apex toward 
middle, a marginal and sub marginal interrupted line, black. Beneath, 
primaries fulvous irregularly marked and mottled with ferruginous lines 
and dark patches. Secondaries at base and costal margin yellow, else 
fuscous somewhat dusted with blue scales along and near anal angle 
and anal half of outer margin ; several more or less distinctly ocellate 
spots, and irregular ferruginous and darker lines varying wing. 
Expands 2 inches, Had. Texas, Mexico, Centr. and S, America. 
ACERONIA, #2. 
This genus has the head broad, the eyes prominent and the body 
robust. Costal nervure dilated for a large part of its course, median and 
submedian swollen or dilated only at base. Anterior tarsi of G exartic- 
ulate, of Q 5 jointed and without claws. In the Synopsis of genera 
anze the distinguishing characters of the genus were pointed out and they 
need not be especially recapitulated here. 
The pupze are slender. braced (i. e. girthed at middle) and have on 
head two earlike tubercles. The imagines are rapid flyers, are said to 
produce a squeaky sound, alight and rest on the trunks of trees head 
downward and with wings expanded. ‘These peculiarities were deemed 
sufficient by Messrs. Doubleday Hewitson and Westwood to authorize its 
elevation to family rank and the butterflies are certainly anomolous 
‘Two species are said to belong to our fauna. 
Wings greenish irregularly marked with zig zag black lines and brown shades feronia, 
Wings mouse gray ; outer $ of primaries white with oblique dark and _ bluish shades 
and circles
