AMERICAN POMOLOGY. 



grass-green, freckled with whitish dots ; with a sharp short 

 point on each side, projecting like horns. 



Ceresa taurina, is like the preceding, but the space be- 

 tween the horns is concave. 



Acutalis dorsalis, is a small, triangular, shining Tree- 

 hopper, with a smooth round back ; it is greenish-white, 

 with a large black spot, from the anterior corners of which 

 a line runs off to ^ach eye. Plentiful about the last of 

 July, a few remaining until October. 



Erythroneura Yitis, (Harris), or the Vine-leaf hopper, 

 is pale yellow, with two broad blood-red bands, and a third 

 dusky one on the apex. Swarms of these small insects 

 occur in August, and often bleed the foliage so as to injure 

 it seriously. 



Erythroneura tricincta, or the Three-banded Leaf- 

 hopper, is like the preceding species, but the bands are 

 narrower. 



Erythroneura Titifex, or the Vine-destroying Leaf- 

 hopper, is yellowish- white ; the wing-covers have oblique 

 confluent, blood-red bands, and a short, oblique, black line 

 on the middle of their outer margin. The thorax com- 

 monly has three red stripes, the middle one forked anteri- 

 orly and confluent, with two red stripes on the crown of 

 the head. When the wing-covers are closed, they loofe 

 red, with a cream-colored spot, shaped like a heart placed 

 anteriorly, and on the middle, a large diamond-shaped 

 spot, with a small red spot in its centre. 



These insects are sometimes seen in such numbers upon 

 the grape vines in September, that, when the leaves are 

 disturbed, they fly out and resemble a shower of snow-
