GRAPE. LEAVES. 



black and curved gently upward. The third joint is of the same length with 

 the second but much narrower, when viewed laterally appearing twice as long 

 as wide and of a square form with the apex cut off obliquely. The last joint 

 is more slender and longer than the preceding two taken together, slightly 

 arched and thicker towards its tip. At its apex two small stout and almost 

 straight claws are articulated at right angles with the foot, and at the base of 

 each claw is a small cylindrical pellet, half as long as the claw and of the same 

 diameter, with its apex cut ofif obliquely. 



The following varieties of this species have fallen under my notice: 

 a. The black dots on the under side of the two first joints of the antennae 



lengthened into short stripes. 

 6. First joint of the antennae with a black transverse stripe beneath, at its 



apex, forming a right angle with a longitudinal stripe. 



c. Two first joints of the antennae with a black stripe on their inner and a 

 black dot on their under sides. 



d. Head without any spot or discoloration above. 



e. discolor at us. The whole of the head, the first joint of the antennae, the 

 breast and abdomen of a brownish clay color. 



f. fuscipes. One or both of the hind legs more or less tinged with blackish. 



g. a/igustipznnis. The male with wing covers a third narrower and somewhat 

 shorter than usual, with the wings protruding like tails from under their 

 tips. Having seen but a single specimen, I cannot regard this as any- 

 thing more than a variety, since in other species of this family we meet with 

 individuals having the wing covers but partly developed. 



With the detailed description of this species which has now 

 been given, it will only be necessary for us to state the more pro- 

 minent points in which the two other flower crickets of our 

 country differ from it. 



We suppose these insects do more mischief by perforating the 

 twigs of different trees to place their eggs in them, causing the 

 dt'ath of the parts thus wounded, in many instances it is probable, 

 tlian by eating the leaves. We are not aware that they ever 

 become so numerous upon vines as to require any exertions for 

 their destruction. Dr. Harris states that they were noticed in one 

 instance piercing and placing their eggs in the branches of a peach 

 tree, and that the tobacco cultivated in Connecticut has sometimes 

 been injured l)y these crickets eating the leaves. Wherever their 

 niiiiibers and operations render them pernicious, the only modo 

 we ai*e able to suggest whereby to abate the nuisance is to pick 

 tjiem from the leaves by hand and destroy them.
