ART. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 153 



BEMBIX GENEROSA. new species 



Figures 107, 108 



Type (female). — Black: clypeus; labrum; mandibles, except tips; 

 frons below level of anterior ocellus, except pair of black spots; 

 scape, except small spot above; broad anterior orbits; broad pos- 

 terior orbits united above: prothorax entirely; broad lateral lines and 

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

 scutellum; metanotum; broad, curved fascia on propodeum; pos- 

 terior surface, lateral angles and sides of propodeum; sides and 

 venter of mesotharax and metathorax entirely; continuous fasciae 

 on tergites 1-6, the first with deep, round, median, anterior emargi- 

 nation, almost inclosed, and pair of shallow, posterior, dorsal emargi- 

 nations, second inclosing pair of elliptical, dorsal, black spots, third, 

 fourth, and fifth biemarginate on anterior border, sixth with anterior, 

 lateral emarginations ; second sternite, except large median and small 

 transverse posterior spot; lateral spots on sternites 3-5 connected by 

 broad, apical bands; legs, except small black spot above on posterior 

 femora; yellow. 



The flagellum, which changes to fuscous at the apex, is black above 

 and yellowish below. The wings are hyaline and the second abscissa 

 of the cubitella is lacking. The anterior metatarsus bears eight 

 spines. The disk of the second sternite is densely covered with 

 minute punctures and is also covered with a very fine, short pubes- 

 cence. The pubescence elsewhere on the body is unusually short and 

 sparse, in fact, almost lacking. The sixth tergite bears a small 

 pygidal area, which is set off by lateral ridges and whose surface is 

 coarsely punctate and shows an evident median carina. The sixth 

 sternite is densely and finely punctate with coarse punctures scattered 

 over its surface, and is accordingly provided with, fine, dense pub- 

 escence, in which are scattered many relatively longer, coarser hairs. 



This species stands close to B. chlorotica Handlirsch, from which 

 it differs in its slightly smaller size and in the character of its 

 maculations. 



Length 16 mm. Described from a single specimen bearing the 

 label, " S. Somala Karo Lola 6. 5. 01, B. v. Erlanger." 



Type. — In the Zoologisches Museum der Universitat, Berlin. 



BEMBIX PIRAPORAE, new species 



Type (female). — Black: labrum; mandibles, except tips; clypeus; 

 lower part of frons produced upward in a stripe on the midline to 

 join a large spot below anterior ocellus ; a smaller spot on either side 

 this large central spot; broad anterior orbits reaching vertex, where 

 they are deflected inward away from eye-margins; scape below;
