G54 Dr. II. Braiins on neto 



cell triangular at apex, with hardly any trace of an appendix. 

 Second cubital cell sessile, triangular. Recurrent nervures 

 interstitial. Third cubital cell nearly rectangular. 



Black ; yellow are the clypeus, a spot on the upper side 

 of the mandibles near the base, the margin of the face ad- 

 joining the clypeus, broadly between eyes and clypeus, two 

 small spots above the antennjB, the tegulffi and the transverse 

 bands of the tergites 1-5, of which the first and last two or 

 tliree are more or less broadly interrupted^ the fifth some- 

 times largely reduced in size. The extension of the bands 

 varies probably within certain limits. The colour of tho 

 bands is paler than clypeus &c. The greater part of the 

 mandibles, scapulas, pygidial segment, and the ventral surface 

 are ferruginous, the tergites except the bands darkish brown, 

 the base more blackish. Legs light brown. Tibite ii. and 

 femora i. and ii. yellow underneath. Median segment and 

 abdominal base thickly clothed with long white pubescence. 

 Wings hyaline, with nervures testaceous. Flagellum of the 

 anteiniEB brown. 



? . — As in the male, but mostly without the yellow spots 

 above the antennse. Abdominal segments not constricted on 

 the sides and above, less narrowed towards the apex. The 

 yellow fascise are broader and more complete. Legs all 

 ferruginous, the femora 1 and 2 yellow beneath, 



Stcrnites without tubercles, the second sparsely punctured. 

 Pygidial segment long, pointed at the apex, the sides raised 

 and carinate. Pygidial area sharply defined, raised, finely 

 and regularly carinate on the surface (about 8-10 longitudinal 

 carinulse). The space between area and edges of the segment 

 smooth and shining. The sixth sternite long, pointed at 

 a[)ex, compressed in the middle. 



The distance of the eyes on the vertex is in both sexes 

 very nearly the same. Tlie female seems to be somewhat 

 smaller than the male. 



JIab. Willowmore, Cape Colony ; nesting in the sand of 

 dry river-beds, November-January. 



The prey of this species comprised Xo»iia, llalictiis, JHfis, 

 &c., in one case a Dipteron ; the latter probably a mistake ! 



Mr. Turner, to whom I sent the species, informs me that 

 tlie British Museum has a pair of this species from the 

 Zambesi and S. Nyasaland, in which all ferruginous colour is 

 replaced by black; but otherwise they agree perfectly with 

 the southern specimens. lie further points out a close 

 relationship witii the Indian I^alarus comben'^ Turner.
