 stripes, sometimes wautiug, one on each side lobe of mesothorax, and a blackish 

 spot behind scutel : legs the color of body, hinder tibiae darkest but having their 

 base pale, all the claw joints of tarsi black ; upper wings white-liyaline, clear 

 at tips, crossed by two wide bands, the first rising neai- base of stigma, the sec- 

 ond beyond its middle and covering the whole marginal cell, with a whitisli 

 clear spot near the apex of stigma; stigma large, dark, whitish at base; under 

 wings hyaline, iridescent, with more or less of whitish above.
