Length of body, from two and one-half 

 to three inches. Color, green or greenish 

 brown, but varying much, becoming quite 

 brown towards the end of the season.

 stripes, the female with only two, one on 

 each side, extending backward from tlie 

 base of the afttenmie.

 short acute spine on the under side, near

 in the fall, and do not hatch till the suc- 

 ceeding year, and sometimes not till the 

 second year. They change but little ex- 

 cept in size and color during their early 

 life, and molt but twice.
