AET. 5 GENERIC REVISION OF THE FOSSORIAL WASPS PARKER 149 



Black: labrum; mandibles except tips; clypeus in part; minute 

 spot between antennae; pair of spots at their insertion; minute spot 

 below anterior ocellus; spot on scape below; anterior orbits, almost 

 obsolete; posterior orbits narrowed and shortened above; fascia on 

 j^ronotum continued on tubercles and sides of prothorax; pair of 

 lateral spots on side of prothorax; lateral lines and U-shaped discal 

 mark interrupted at midline on scutum; fascia on posterior border of 

 scutellum; fascia on metanotum; curved fascia on propodeum ex- 

 tended on posterior surface and narrowly interrupted ; lateral angles 

 and side (in part) of propodeum; vertical spot on metapleura; tri- 

 angular spot on mesopleura ; continuous fasciae on tergites 1-5, first 

 with pair of rounded dorsal and pair of pointed lateral anterior 

 emarginations, second and third narrowed at midline and each en- 

 closing pair of discal spots, fourth and fifth broadly biemarginate 

 on anterior border; pair of lateral spots on sternites 2-5, those on 

 second and third extended and attenuated medially; femora, except 

 line on both anterior and posterior surface; tibiae, except line on 

 anterior and posterior surface of first and second pairs and on pos- 

 terior surface of third pair ; and tarsi ; yellow. 



The markings on the thorax and abdomen are bright lemon yellow ; 

 those on the legs are darker in shade ; the markings on the head are 

 very pale. The flagellum is black and the wings are hyaline. The 

 pubescence is light in color and normal in development. The sixth 

 tergite is roundly pointed and is uniformly and rather coarsely 

 punctate, except at the apex and on the midline of the posterior half 

 of the tergite, which are devoid of punctures. The f rons is relatively 

 broader than usual and the inner eye-margins are parallel. The 

 black basal border of the clypeus on one specimen is expanded at the 

 midline so as to reach almost to the ventral border of the sclerite; 

 on the other specimen the black is confined to a pair of irregular 

 basal siDots.

Type (female). — Black: labrum; clypeus, except a pair of narrow 

 lines paralleling the basal margin; mandibles, except tips; frons to 

 level of anterior ocellus, except pair of large black spots; scape, 

 except small apical spot above; anterior orbits deflected inward at 

 anterior ocellus and reaching almost to vertex; posterior orbits 

 broad below; prothorax, except three anterior black dorsal spots; 

 broad lateral lines and long, narrow discal lines on scutum; fascia 

 on posterior border of scutellum; fascia on posterior border of 

 metanotum; curved fascia on dorsum of propodeum broadly ex- 

 tended on posterior surface; lateral angles and sides of propodeum 

 almost wholly; metapleura; mesopleura almost completely; broad
