This sp«scies is, in most instances, easily distinnnisiiable by the little 

 tuft of yellow scalers just behind t luwolla-r, eonddui'd with the t^levaied 

 vestilur(^ and tln^ j;(MM'ral patltMii of llu^ winj;-. In the fennde there is a 

 tuft ol' luiir lik«^ scldes, \ iiryiuj;' from yellow to bhudc, visible betweeu 

 tw«>of tlu^ s(>>;uMMits near the t ip of the abdonuMi. As a. rule these hairs 

 are yellow; but the.\ may vary all tlie way to blackish, ltisth(^only
