AKT. 5 GENERIC REVISION OF THK FOSSORIAL WASPS PARKER 91 



The wings of the male are slightly and uniformly infumated 

 while those of the female have the apical third clear and the basal 

 two-thirds heavily infumated. On one of the two female paratypes 

 the lateral spots on the tergites are lacking and on the other much 

 reduced and on both the ferruginous on the terminal segment is 

 much reduced.

BEMBIX DORIAE Magretti 



Bcitibex doriae Magketti, Ann. Mus. Geuov.. vol. 21, 18S4, p. '/M. — IIaxulirsch,

There is in the collection of the United States National Museum a 

 single male of this species determined by Magretti. The basal half 

 of the wings is heavily infumated, the apical part clear. The an- 

 tenna, with the exception of the last three segments of the flagellum, 

 is ferruginous, and segments 7-9 of the flagellum are spinulose be- 

 neath. The maculations of head, thorax, propodeum, and legs are 

 ferruginous with a show of yellow on the labruni and mandibles, and 

 on the tibiae and tarsi, especially on the hind pair. The clypeus 

 shows a marked silvery pubescence. Maculations on the thorax are 

 reduced to a narrow line on the pronotum, spot on side of prothorax, 

 tubercles in part, and small lateral spots on scutum above base of 

 wings. On the propodeum the only maculations are spots on tlie 

 posterior lateral angles. The fasciae on tergites 1-5 are yellow and. 

 very broad. The first is abruptly narrowed and interrupted at the 

 middorsal line; the second incloses a pair of narrow transverse discal 

 spots; and the third, fourth, and fifth cover practically the entire 

 surface of their respective tergites. The visible surface of tergites 

 and 7 are ferrugThous. All sternites are ferruginous with 2-r) 

 bearing small lateral yellow spots. 



The middle metatar.sus on its lower surface at the middle bears a 

 prominent, longitudinally compressed, thin dilation. The second 

 and sixth sternites bear prominent processes. The specimen was 

 taken at Keren, Eritrea, February 27, 1900.

The male of this species, with regard to structural characters, 

 stands close to donae Magretti. It differs from that species in 

 having the fasciae on the tergites pale instead of yellow, and in
