pollen on the body is thicker and more extended than in the 

 European species; the crossbands of its wings are incomplete.

Head yellow. Front brighter yellow, almost orange-red upon 

 its anterior end ; on each side with a conspicuous border of white 

 pollen, which, becoming broader, extends below over the face as 

 far as the cheeks. The occiput becomes blackish above, but is 

 rather evenly covered with a rather thick whitish pollen. The 

 ground color of the thorax is rather black, more brownish on the 

 humeri and upon the lateral border, as well as below the root 

 of the wings ; this color, in well-preserved specimens, is covered 

 by a grayish-white pollen ; upon the thoracic dorsum there are 

 two longitudinal stripes, of a somewhat darker color, very little 

 apparent and abbreviated posteriorly. The color of the scntellum, 

 which is likewise covered with gray pollen, verges more on 

 dingy brownish, and on clay-yellow along the edges ; in less 

 fully colored specimens the whole scutellum is clay-yellow. The 

 color of the abdomen is likewise rather black, sometimes only 

 brown at the basis. In the male, this color appears distinctly as 

 black or brownish-black upon the last segment and on the hypo- 

 pygium, both of which are pollenless, while on the preceding 

 segments this color is concealed under a rather thick pollen, 

 which on the anterior portion of the segment has a light whitish- 

 gray, on the posterior half a brown coloring. The female has the 

 last abdominal segment likewise pollinose, the pollen being 

 generally light white-grayish, or verging on brownish about the 

 middle of the abdomen only; the pollen on the preceding 

 segments is the same as in the male. The first segment of the 

 altogether flattened ovipositor is not very long, but very broad 

 and very broadly truncate at its end; its pollen is very little 

 perceptible, so that it is glossy-black, more brownish-black in
