\ Separating nervure between the radial and cubital cellule arcuat 

 edj second cubital cellule not very much elongated, 



1. B, pectindtor. Black; abdomen yellowish ; wings 

 blackish ; cellules regular. 



Inhabits United States. 



Head rather la 

 neck : rostrum not prominent : thorax with the dorsal 

 sutures dilated and containing very obvious transverse 

 lines; the transverse suture at base of the scutel with 

 five elevated lines: wings dark violaceous; 2d cubital 

 cellule shorter and smaller than the first, quadrangular ; 

 nervure forming the radial cellule rectilinear : oviduct 



exsertedj black.

I am not certain whereabout this insect was captured, 

 but I think 1 obtained it in the N. W. Territory when 

 enc^ac^ed on the northern expedition witTi Major Long. 



It resembles the populator^ but the rectilinear form of 

 the nervure of the radial cellule places it nearer rugator^ 

 Nob. and initiator, F.; from the former it is distinguished 

 by the more simple surface of the tergum^ and from the 

 latter by the much shorter second cubital cellule.

and 



ickish ; tergum \^
