180 PROCEEDINGS OF THE ACADEMY OP 
margin, four large oblong spots of black proceeding from tbe exterior margin, 
the two intermediate ones reaching beyond the middle of the wing, the others 
shorter, with each a small fulvous spot near the tip ; and four spots of black 
descending from the sub-costal nervure, of which the one nearest the body is 
linear, the next square, the third roundish with a fulvous spot in the centre, 
and the fourth connate with the fourth of the before mentioned spots proceed- 
ing from the exterior margin. 
The lower wings are above bluish black, changing to brownish fulvous near 
the base, with an indistinct whitish spot below the centre. 
The under side of the upper wings has seven spots of pearly white parallel 
with the outer margin, of which the five exterior ones are linear, and the two 
others round ; from these two round spots proceed two oblong black spots to 
the middle of the wing, and the two next have each a round black spot above 
them. From the sub-costal nervure proceed four black spots, of which the two 
nearest the body are linear, the next triangular, enclosing a fulvous spot, and 
the fourth is almost confounded with the black upper margin. 
The under side of the lower wings is brown, with four white sublunate spots, 
bounded above and below by black, and parallel with the lower margin ; there 
are likewise two long black spots outside of the outer one of these spots : the 
whole base of the wing is occupied by six large pearly spots radiating from the 
axilla, one of which occupies the pre-costal portion ; between the second and 
third (which are very wide) is a smaller spot, and the third is crossed near its 
base by a short black bar. The emarginations of the wings are margined with 
white. Body black, thorax thickly covered with brownish fulvous hairs. 
The above described Lepidopteron so nearly resembles the Argynnis Idalia, 
that at first sight it may easily be taken for a mere variety. The want of the 
double row of white spots on the upper surface of the lower wings, although a 
remarkable difierence, would not perhaps constitute a specific mark, yet when 
we come to examine the under surface, instead of the twenty-four or twenty- 
five spots of white, which are observed over its whole surface, we find but 
two near the margin and six large ones occupying nearly the whole of the 
base, and radiating from the axilla, we cannot hesitate to pronounce it distinct 
and certainly new. The larva is unknown. The interesting fact of so large a 
species of butterfly being found at this time in New Jersey, and having hereto- 
fore escaped the researches of all entomologists, has led me to offer this short 
communication for publication in the Proceedings. It was found by me in 
July of this summer, on Succasunna Plains, near Schooley's Mountain, in 
Morris Co. 
Note on the species of ELEODES found within the United States. 
BY JOHN L. LE CONTE, M. D. 
Having a number of nondescript species of Eleodes, which it becomes neces- 
sary to mention in a Catalogue of the Coleoptera of the TJ. S. and Mexican 
Boundary, now preparing for the press, I have considered it proper here to 
present descriptions of these species ; and for the purpose of elucidating their 
characters in the absence of a monographic essay, the following grouping of 
the species in my collection belonging to this very difiicult genus may be found 
useful. They are now very numerous, and quite heterogeneous in form, though 
tbe antennae and oral organs do not seem to have much variation. 
A. Elytra subconvex or depressed, oblong oval, margined or not, more or 
less sulcate (but in E. dispersa almost irregularly punctured and not striate) ; 
humeral angles distinctly margined. Presternum never mucronate ; anterior 
tarsi with the first joint inflated beneath and densely clothed with short bristles. 
Anterior femora toothed ; anterior tibiae of the females with the outer spur 
usually larger and broader than that of the males. 
A. Humeral angles not prolonged.
