Sub-order, Homoptera ;) • [Living upon the twigs of the apple, peach, ai)ricot, almondand plum trees; a green leaf-hopper, shaped something like abeechnut, with two short spines jutting out horizontally fromeach side of the anterior end, having some resemblance to thehorns of a l)ull oi- buffalo.] 72 INSECTS INFESTING THE APPLE TREE. These insects obtain their nourishment by puncturing thetwigs with their beaks and imbibing the sap. Fiff 33 ^^^- ^^—Bi^^ff^lo Tree-hopper—color, green ; a, side view 6, back Fig. 35. Fig. 34.—Eggs of Buffalo Tree-hopper; a, an egg, highly-magnified ; fe, eggs natural size in a twig. Fig. 35.—Larva and pupa of Buffalo Tree-hopper, enlarged ; a, the larva—color brown-ish ; h, the pupa—color greenish; c, the ovi-positor of the adult female, magnified. From specimens of this insect (Fig. 33),and branches containing eggs (Fig. 34), re-ceived from several places in this State, andalso from the State of Nevada, I am inclinedto think that from eight to twelve eggs arelaid in each young (Fig. 35) hatch in —No. 28 and No. 25.
