of the genera in this family upon differences in the shape of the thorax, and 
disregards analogous differences here, especially since these differences are not 
in the least sexual here as they are in some of the other genera. I am there¬ 
fore induced to retain the genus Smilia for those insects to which it was applied 
by Amyot and Serville, being a portion of the first section of this genus as it 
was originally proposed by Germar, and the equivalent of the first and second 
sections of M. Fairmaire’s genus Thelia; his third section being the same with 
my genus Telamona, and his fourth section being the Thelia of Amyot and Ser¬ 
vile, and of the present Report. 
22. Buffalo trek-hopper, Cercsabubalus, Fab. (IIomoptera.Membracidse.) 
[Plate ii, fig. 4.] 
A tree-hopper of similar form and the same habits with the 
preceding, appearing on this and most other trees from July till the 
end of the season. Color light grass-green when alive, freckled 
with whitish dots; anteriorly with a short sharp point on each 
side, jutting horizontally outwards, having some resemblance to 
the horns of a bull or buffalo. Length 0.30 to 0.40. 
23. Calf trek-hopper, Ceresa taurina, new species. 
This is like the preceding in every respect, except that the 
space between the horns is concave instead of rectilinear. It is 
the insect named Membracis taurina in Dr. Harris’s Catalogue, and 
perhaps is not a distinct species from the foregoing. 
Several other kinds of tree-hoppers and leaf-hoppers occur 
upon apple trees, but being more common on oaks, willows, and 
other trees, will be noticed hereafter, each in connection with the 
tree to which it appears to be most attached. Several ot these 
insects puncture the tender bark of the small limbs as well as the 
leaves. 
24. Largf, tree-bug, Jtrma grandis, Dallas. (Ilemiptera. Pentatomidae.) 
[Plate ii, fig. 7.] 
A large flat bug, the size and somewhat the shape of a pumpkin 
seed, but with a conspicuous sharp spine projecting outwards on 
each side anteriorly. Color dull pale yellowish, with numerous 
minute brown punctures above and red ones on the under side, and 
with two burnished brassy green dots near each anterior angle ot the 
thorax. Length of the male 0.G0, female 0.75. Appearing on 
apple, oak and other trees from July till the end of the season.
