strongly exserted outwardly below the median : the posterior 

 line more prominently dentate, with three teeth between costa 

 and vein 3, above which vein it is strongly bent inward so as 

 to touch the lower end of the reniform and to extend beyond 

 it for a space equal to its transverse diameter, thence curving 

 outwardly, and with two ang illations reaching the internal 

 margin. There is a faint trace of a median shade running as 

 a continuation of the lower half of the posterior transverse line. 

 The thorax is concolorous with the wings, and together with 

 the prothoracic tufts and head, is marked with a median 

 brown line. The two basal segments, have each a small black 

 median tuft, a trace of one of which is visible in the Center 

 example, the other having probably been lost in the partial 

 denudation of the superior portion of the thorax. The an- 

 tennal structure of the two examples is the same, and no 

 material difference is noticeable in a comparison of the pos- 

 terior wings.
