Four pale examples are also quite variable. One has the front and hind 

 surfaces of the femoral region with rather large dusky vermiculations strongly 

 contrasted with whitish. In this individual there is also a dark-gray inter- 

 orbital band. Another shows a number of whitish spots on the middle of the 

 back with broad whitish band back from each eye to groin. The lower sur- 

 face of the body is often uniform whitish. 



Large darker olive or brownish examples are more or less uniform in color, 

 though one shows pale areas back from the eye to the groin. They usually 

 have the right and front femoral regions and groin finely speckled brownish 

 on pale ground-color. Most are more or less smutty below. 



In a number of small darker examples traces of the light areas back from 

 the eye are seen in two cases and in one of these an accessory short inner line 

 backward and parallel is also present, while the larger bands tend to converge 

 at the middle of the back. All have the limbs above with more or less obso- 

 lete dark cross-bars. A dark interorbital band is also usually in evidence. 



All examples have the dark line from the eye over the tympanum distinct.
