Remarks. ^ — Both the normal and the hilineata types occur in our 

 range, the normal being vastly in excess of the latter type, which 

 may be regarded as relatively scarce. In addition there is much 

 variability as regards color and markings in different individuals, 

 these occurring indifferently in both the normal and bilineata types. 

 Of the color varieties there are, (a) a form with the ground color a 

 light olivaceous; (6) one in which it is green; (c) a form which may 

 have either of these two ground colors, but has more or less of the 

 upper surface a bright crimson or orange, instead of the usual pale 

 broum. Of the variations in markings there are two forms, one in 

 which the body color is practically uniform, another in which it is 

 conspicuously mottled with darker blotches of black or brown. 

 In our region the most frequent type is the uniformly colored, 

 olivaceous variety, but the others are by no means infrequent.
