 the metanotum, where punctures occur, parallel carinas also traverse the superior 

 aspect of the metatborax longitudinally ; thorax black, excepting the tubercles 

 and a line prolonged anteriorly therefrom, tegulae, a line beneath the same, pos- 

 terior margin of the scutellum and a line on the postscutellum, which are white ; 

 wings hyaline, nervures dark brown, except at the base of the wing, where they 

 are colorless, stigma pale brown, anterior and posterior corner whitish, the lower
