Ain. 5 GENERIC EEVISION OF THE FOSSORIAL WASPS PAEKER 93 



short prominent lateral carinae. The seventh tergite is deeply 

 sinuate laterally, narrowed and truncated at the apex. 



The allotype (female) differs but slightly from the type with 

 respect to its maculations; the lateral spots on the scutellum are 

 continued by narrow lines that almost meet at middorsal line; there 

 is a broken line on the metanotum; there is a narrow fascia on the 

 propodeum and the spot on its lateral angle is larger; the fascie on 

 the first tergite is continuous but narrowed dorsally; that on the 

 second incloses a pair of black spots; the apex of the fifth tergite is 

 ferruginous and the sixth is wholly so. The antenna is ferruginous, 

 but the scape, the first segment of the flagellum and the base of the 

 second are black above. The apex of the flagellum is darker than 

 the rest of it, but the contrast is not so great as on the type. The 

 sixth sternite is ferruginous and carinate on the midline. The disk 

 of the second is smooth and bears on either side the midline numer- 

 ous coarse punctures. The sixth tergite is triangular in outline, 

 rounded at the apex and bears, except along its median part, 

 numerous, short, stout spinelike hairs. 



The wings in this species are lightly but uniformly infumated, the 

 infumation being somewhat more pronounced in the female than in 

 the male. The pubescence is of normal character. The clypeus is 

 strongly arched and only slightly carinate at base. The frons be- 

 tween the antennae likewise is only weakly carinate. The anterior 

 metatarsus is provided with six spines. On both type and allotype 

 the ferruginous bands between the lateral yellow spots on the sternites 

 inclose more or less black that may take the form of a narrow trans- 

 verse line. Of the paratypes (females) two have the fascia on the 

 first tergite interrupted and the base of the clypeus strongly bordered 

 with black, and one of the two has both the metanotum and propo- 

 deum without maculations. On both, the fascia on the second tergite 

 has a pair of deep anterior emarginations instead of the inclosed black 

 spots found on the allotype. A third has the markings on the thorax 

 and propodeum white. On this specimen the antennae are almost like 

 those of the type in color. 



The type of this species was received in an exchange and had been 

 identified as Beinhex capensis Lepeletier by R, H. R., Stevenson, for 

 Avhom the species is named. The original description of B. capensis 

 Lepeletier states that the antenna is black, whereas in this species 

 the scape and the first eight segments of the flagellum are ferruginous. 

 Furthermore, in this species neither the clypeus nor the labrum is 

 marked at all v/ith black and the process on the sixth sternite, instead 

 of being small and subacute, is prominent, broad, and rounded at 

 the apex. It is further distinguished from capensis by the infumated 

 wings.
