Vol.1] Bradley. — The Taxonomy of the Masarid Wasps 399 



The rather long neck, and the shape of the head and prothorax are 

 suggestive of Xiphydria; the humeri entirely rounded, parapsidal fur- 

 rows absent; scutellum in the genotype with a median furrow and 

 ending in two tubercles, in saussurei, however, simply longitudinally 

 concave ; tegula elongate, bluntly rounded, not pointed posteriorly, 

 covering the base of the scutellum, its outer margin entire, coarsely 

 punctured ; propodeum concave posteriorly, its side rounded, not cari- 

 nate, but superiorly mucronate or dentate. 



Medio-cubital cross-vein opposite M^ -j- Cu^ ; anterior trochanter 

 unarmed ; the tarsal spur arcuate, simple ; the tarsus not much short- 

 ened and flattened ; femora and tibiae with simple surfaces ; middle 

 tibia in the genotype with one large apical spur beneath and an addi- 

 tional short stout spine at apex on the upper side ; in saussurei. there 

 are two stout spurs beneath and one above ; the posterior tibial spur, 

 bifid as in Pseudomasaris ; claws with a small tooth beneath near the 

 base. 



Abdomen cylindrical, the last dorsal segment unarmed, the apical 

 margin broadly emarginate ; ventral segments unarmed, the seventh 

 of the genotype with a deep depressed pocket at base extending be- 

 neath the sixth segment, its apex except in saussurei broadly, not 

 deeply rectangularly emarginate, the apical border in the middle of 

 the emargination produced into two teeth with a deep rounded notch 

 between. 



Genitalia not examined. 



5. Differs from the male in the following particulars: clypeus 

 convex but not gibbous; antennae much shorter, the segments of the 

 flagellum short, fonning a compact oval club, not unlike that found in 

 females of Pseuelomasaris: spur of anterior tibia shorter and broader; 

 anterior tarsus shorter and flattened ; abdominal segments as in female 

 Pseud&masans, the apical segments unarmed and broadly rounded at 

 apex. I have not dissected the mouth parts, but the labial palpi have 

 three segments, the third equal to the second, and bearing one or more 

 stout curved spines near the apex, and there may be a fourth segment 

 represented by a minute tubercle ; the maxillary palpi I cannot make 

 out. 



Type. — Masaris edfkeni (Du Buysson), genus monobasic. 



Habitat.— ^outh Africa. 



Key to the Species of MASAEIELLA 

 Male.s 



Club of antenna elongate, oval, not sharply differentiated from rest of flagellum, 

 slightly hooked at tip and flattened beneath; seventh ventral segment with 

 a conspicuous deep basal pocket, extending beneath the sixth, its apical 

 margin broadly rectangularly emarginate, in the middle with two teeth separ- 

 ated by a deep and rounded median notch alfkeni (Du Buysson). 



Club of antenna very short, broadly ovate, convex beneath, shaped as in Pseudo- 

 masaris texana, the tip bluntly rounded, not hooked; seventh ventral segment 

 slightly produced and truncate at apex, considerably obscured by numerous 

 long silky hairs at its base with a weakly marked shallow pocket extending 

 beneath the sixth segment ....: '. saussurei Brauns.
