The reasons for the s}'nonymy given above were set forth in my 

 previous paper on the Bembicine wasps and need not be repeated 

 here. This species is well marked and is not likely to be confused 

 with any other species thus far described from North America. 



SPECIMENS EXAMINED 



Texas: CotuUa (May 5, 1905, W. D. Pierce). 



Wi8CX)nsin: North Hudson, St. Croix County (July 7-12, 1910). 



This species has been reported also from Georgia, Kansas, and 

 Louisiana.

This species, which is known only from the type (a female) in 

 the United States National Museum, may be readily recognized by 

 its unusually long, narrow labrum and its rugose sixth tergite. 

 When this species was described I raised the question of the possi- 

 bility that this may be the female of Berribix stenehdoma Parker, 

 rot so much because of the resemblance of the two sexes as because 

 of the resemblance of the male and female, respectively, to the male 

 and female of Bembix helfragei Cresson. But until more evidence 

 is available I do not think it proper to associate the two as sexes of 

 one species. The type bears simply the label "Ariz." 



BEMBIX INTEGRA Panzer 



Bembex Integra Panzer, Faun. Ins. Germ., vol. 8, 1805, p. 84. — Handlirsch, 

 Sitz. Akad. Wissensch. Wien, Math.-Nat. CI., vol. 102, 1893, p. 701.— 

 Dalla Torre, Cat. Hym., vol. 8, 1897, p. 506. 



The male of this species, with respect to the dilation of segments 

 2-4 of the anterior tarsus and of the middle metatarsus, resembles 

 zonata, but on this species the dilation of the anterior tarsus is 

 marked with black, which is not the case on zonata. The middle 

 femur on this species has the posterior border distinctly curved and 

 strongly dentate, whereas on zonata it is straight and not dentate.
