series of large squarish or irregular dark brown or black spots between 

 the light dorsal lines, wliich may be edged with black. In males, 

 which are often green all over, and permanently, including the light 

 dorsal streaks, the spots may be accompanied by numerous black dots. 

 Some specimens lose more or less completely the markings and are 

 uniform green above, or green finely speckled with black as we often 

 see in L. viridis. Females are usually grey or brown, but sometimes 

 green like the males." A female from Miunusinsk, Yenissei, is pale 

 reddish brown, with a yellowish vertebral streak and a bluish grey 

 dorso-latei'al band ; only scanty vestiges of the ocellar spots on the 

 sides. Schreiber describes a var. concolor, uniform olive brown. 



Lower parts yellowish or greenish white, or yellow, uniform or 

 dotted with black, the dots usually more profusely distributed in 

 males than in females.

 the Kirghiz Steppes the females are brown. A similar coloui'-diraorphism in 

 females, according to districts, appears to occur also in L. vii-idis.
