 body tinged with yellowish brown, this tinge being more

 prominent and much larger than the second segment; 

 it is of a dull reddish-brown color, edged with black on 

 the hinder part, and clothed with minute whitish hairs. 

 The body is dull brownish green, with hairs similar to 

 those on the head ; a dorsal line and numerous dots over 

 the surface of the body are of a darker shade. Joint 2
