ART. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 87 



10 and 11 are deeply excavated; and segment 12, which is longer than 

 the preceding segment, is strongly curved, squarely truncate at the 

 apex, and its posterior apical angle forms an evident point. The 

 anterior metatarsus is broad and bears five stout spines. The middle 

 femur is plain. The second sternite is plain and the sixth has at its 

 middle a low, rounded elevation that can not be classed as a tubercle 

 or process. The seventh bears an evident median carina bordered on 

 either side basally by a less evident carina. The seventh tergite bears 

 a pair of evident, nonspinose. lateral angles and at its apex is 

 strongly emarginate. 



Allotype (female).. — The allotype in color and maculations very 

 closely resembles the type. The Hagellum below is not so light, the 

 metanotum is wholly black, the fasciae on the tergites are narrow 

 and all, except that on the fourth tergite, are interrupted medially; 

 that on the fifth is reduced to widely separated lateral spots. Lateral 

 spots are borne only by sternites 2 and 3. The maculations on the 

 legs are somewhat better developed than on the type and the tarsi 

 show the same markings borne by the type. 



The anterior metatarsus bears only five spines. The inner eye 

 margins are only very slightly divergent at the clypeus. The lateral 

 parts of i\\B second sternite are closely covered with relatively fine 

 punctures; toward the mid line the punctures are fewer and coarser; 

 while on the mid line there is a narrow longitudinal area devoid of 

 punctures. The abdomen shows a beautiful purplish irridescence.

I have before me eight males and three females that I have referred 

 to this species. The males, with respect to the antenna, the middle 

 femur, the second and sixth sternites, the seventh tergite, and the 

 genital stipites, agree with Handlirsch's description of the species. 

 The maculations, however, can hardly be termed yellow; they are 

 more nearly white with a faint yellowish or creamy tinge. While 

 the different specimens show some variation in the extent of the 

 maculations, this variation is no greater than that which Handlirsch 

 points out in his description. 



Of the three females that I have referred to this species the macu- 

 lations are decidedly yellow, but on the tergites they are less exten- 

 sively developed than on the males. On two of the females the
