APPLE. LIMBS. 



of the genera in this family upon dilFerences in the shape of the thorax, and 

 disregards analogous dilFerences 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 lirst 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- 

 ville, and of the present Report. 



22. Buffalo TREE-HOPPER, Ceresabubalus,Ya.h. (Ilomoptera. Mem br acid ie.) 



[Plate ii, fig. 4.] 



A tree-hopper of similar form and the same habits with tlie 

 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 tree-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 of these 

 insects puncture the tender bark of the small limbs as well as the 

 leaves. 



21, Large tree-bug, Arma grandis, Dallas. (Ilemiptera. Pentatomidai.) 



[Plate ii, fig. 7.] 



A large flat bug, tlie size and somewhat the shape of a pumpkin 

 seed, but witli a coiLSpicuous sharp spine projecting outwards on 

 each side anteriorly. Color dull pale yellowisli, witli numerous 

 minute brown })Uiicturcs above and red ones on the under side, and 

 with two Iturnislied brassy green dots near eacli aiitrrior angle of the 

 thorax. Length of the male O.GO, female 0.75. Appearing on 

 apple, oak and other trees from July till the end of the season.
