THE TREE-HOPPERS. 221 



maculata of Fabricius and imivittata^ of my Catalogue have 

 a thin horn-hke projection, blunt, however, at the end, ex- 

 tending obliquely forwards and upwards from the fore part 

 of the thorax; and M. hinotata and latipes'^ of Say have a 

 similarly situated horn, narrower hoAvever, and curved, so 

 as to give to the insects, when viewed sidewise, the shape 

 of a bird ; and, lastly, in 31. bubalus of Fabricius, dicer os 

 of Say, and taurina^ of my Catalogue, the ridge of the tho- 

 rax, view^ed from above, has somewhat the shape of the 

 letter T, becoming broad at the fore part, and extending 

 outwards on each side like a pair of short thick horns, which 

 gave rise to the foregoing specific names, meaning buftalo, 

 two-horned, and kine-like. 



The habits of some of the tree-hoppers are presumed to 

 be much the same as those of the musical harvest-flies, for 

 they are found on the limbs of trees, where they deposit 

 their eggs, only during the adult state, and probably pass 

 the early period of their existence in the ground. Others, 

 however, are known to live and undergo all then' changes 

 on the stems of plants. Among the former is our largest 

 native species, the two-spotted tree-hopper, or Me7n- Fig. §9. 

 bracis bunaculata* of Fabricius (Fig. 89), which 

 may be found in great abundance on the limbs of 

 the locust-tree (^Robinia pseudacacia) during the 

 months of September and October. These, as well 

 as other tree-hoppers, show but little activity when undis- 

 turbed, remaining without motion for hours together on the 

 limbs of the trees ; but on the approach of the fingers, they 

 leap vigorously, and, spreading their wings at the same time, 



* Fabricius describes the male only under this name; the female i* his ^^em- 

 bracis acuminata. This species belongs to Professor Germar's new genus, Htmi- 

 ptychafi 



[ 6 M. bimaculata and univiltata belong to Thelia, Amyot. — Uhler.] 

 [ T 3f. binotata and latipes belong to Euchenopa, Amyot. — Uhler.] 

 [ 8 M. bubalus, diceros, and taurina belong to Ceresa, Amyot. — Uhler.] 

 [ 9 It might be added, that this genus is now resti'icted to Jlembracis jnaictata, 

 Fab., and a few allied species. — Uhlek.]
