This species is named in honor of Mr. Bnumer whose ohservM- 

 tions of the life history enabled the differentiation of this species 

 from the very similar Sesia novarcensis Hy. Ed\v., which lives in

 varcensis in the blue, not black, ground color and in the much 

 less extensive red abdominal coloration.
