by the black legs from dama Fabr. (capreolus, Lin). which has brown legs 
(especially light femora) and by the chestnut-brown color of the upper 
surface from the Q O of flacidus and mazama which are black. Occurs 
in N. C., Va., Ills, Ind Terr. Length of ¢ 34-55m. 
The mentum in the Q c/aphus is comparatively long- 
er, the anterior angles are very much less rounded and 
the part asa whole much more quadrate than in the

The antennz fig. 1 are geniculate as are all the 
others of this genus; in the an they are more slender 
than in dama or any other of our American species: 
Fig. 1 the joints are proportioned as in the figure, and the 
sixth joint showsno trace of dilatation; the joints except the terminal three 
are entirely glabrous, minutely punctulate, and set with a few sparse hair: 
the 7th joint is produced inwardly, forming the first of the pectinations; 
the 8th and gth are longer, glabrous at the outer side but the inner side 
brown opaque, densely clothed with fine hair: the terminal joint is en- 
tirely opaque and densely pubescent: the form of the joints is better 
shown by Mr. Smith’s excellent figure, (Fig. 1) than any description of 
mine can do,

Quite common in N.Y., Pa., Ills., D,C.—Length 23-35 mm: 
The larva of this species lives in beech and oak, it is 14 inches in 
length, of the usual Scaradid form, curved inward, ofa whitish color more 
or less discoivred by the contents of the intestines; the s/igmafa and head 
are luteous, the mandibles piceous: the figure on the plate shows the gen- 
eral appearance of the larva better than any description: the mandibles are 
strong, corneous, curved, with a prominent tooth near base, two small 
denticles on the inner side of the curve and three very distinct and strongly 
marked teeth at tip. The antennze are moderate, 4 jointed the second 
joint longest, the first less than one half as long, third one-third shorter 
and dilated at tip: terminal joint very small, set at the inner side of the 
third joint: A few rather stout hairs on each joint: the mouth-parts are 
all stout fleshy: the maxilla is moderate, heavy, as usual in the scarabidee; 
the palpus 4 jointed short, the joints nearly ejual in length but gradually
