Figure 11. — Localities for Hemipepsis ustulata ustulata. 



Forewing of male 15 to 25 mm. long, of female 17 to 27 mm, long. 

 Blackish color at wing bases conspicuous, extending on the wing bases 

 more than half the length of the anal lobe. 



Banks proposed the name cressoni for this form because Dahlbom 

 described his ustulata from "Mexico" and mentioned a bluish colora- 

 tion. The female of the present form does have some bluish irides- 

 cence, and it must be remembered that in 1842 much of what is now 

 in the southwestern United States belonged to Mexico. Miss Louise 

 Russell has compared specimens from Texas with Dahlbom's type for 

 me, and reports that they agree very well.
