This species conies very near E. peregrinus, Ckll., but 

 differs in the following details : — The markings of griseous 

 pubescence in E. peregrinus take the form of " subdorsal 

 spots " on tergites 3-7, in the present species the pubescence 

 is in interrupted fasciae; the second cubital cell is sub- 

 triangular in the former species, in the latter there is a 

 distinct abscissa of the radius ; tlie head and thorax of the 

 former are distinctly shining, with the punctures compara- 

 tively scattered, in the latter they are dull and very close.
