 base of the honey tubes ; the antennae, knees and feet are black. 



The winged female (Fig. 267, 1,) is either dark green or 

 brown, with a row of black dots on each side of the body ; 

 the head and thorax are sometimes marked with black. 



The present season, 1883, this species appeared in at least 

 ten counties in this State, and in some instances did consider-

 entirely with the ad- 

 vent of the rain of 

 May 4, 1883.
