ABT. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 147 



This female is smaller than the male Cameron described, being less 

 than 20 mm. in length. The anterior metatarsus is broader and 

 flatter than usual in this genus, thus agreeing with the male from 

 which the species was described. In this respect it resembles Bembix 

 palmata Smith, but the dilation of the anterior metatarsus is less 

 pronounced on this specimen than on palmate. The clypeus bears a 

 pair of large, basal, black spots; the scutellum and metanotum each 

 bears a narrow, interrupted fascia, and the scutum bears a broken 

 U-shaped discal mark. The propodeum bears a prominent curved 

 fascia, and the sides of the thorax and propodeum are yellow, except 

 a black spot below the tegula on the mesopleura, another in front 

 and above the middle coxa, and a vertical black stripe on the pro- 

 podeum. The fasciae on tergites 1-5 are narrow, the first inter- 

 rupted, the second inclosing a pair of black discal spots, and the 

 third, fourth, and fifth biemarginate on anterior border. The yellow 

 on the sternites is limited to small lateral spots on 2 and 3. The 

 anterior metatarsus is provided with only five spines.

I have at hand a single female that I have referred to this species. 

 On the lateral border of the clypeus running to the ventral margin 

 is a short but deep depression, causing the clypeus at this point, 

 when viewed from in front, to appear to overhang the base of the 

 mandibles. With regard to the maculations, this specimen agrees 

 with Handlirsch's description of the species. It is from Australia 

 and bears the label, " N. Queensland, Coll. Bingham."

 except large medial black spot ; scape below ; f rons between antennae; 

 broad but shortened anterior orbits; three spots on frons below the 

 level of anterior ocellus; pair of spots on vertex not connected with 

 orbits; broad posterior orbits, above extending inward and down- 

 ward on the occiput ; prothorax almost wholly ; broad lateral lines and 

 U-shaped discal mark on scutum; broad fascia on posterior border 

 of scutellum; fascia on metanotum; broad, curved fascia on pro-
