Females 



Propodeum with posterolateral angles weakly angled above but not dentate; 



scutellum with a discal depression, not ending in two tubercles 



saussurei Brauns. 



Propodeum with its posterolateral angles dentate above; scutellum with a longi- 

 tudinal median fossa and ending in two tubercles alfkeni (Du Buysson). 



M. saussurei undoubtedly is more closely related to alfkeni than it 

 is to the genotype of Masaris, in which genus it has heretofore stood, 

 as the following considerations will show. In Masaris the ventral 

 segments two and three are both armed with strong processes, in 

 alfkeni is probably more like it than that of saussurei; the ocelli of the 

 ment is elongate, tapered, and ends in two prominent tubercles or teeth, 

 while in both alfkeni and saussurei it is short and rounded, the apical 

 margin broadly emarginate; in both alfkeni and saussurei the larger 

 spur of the hind tibia is bifid, but not so in Masaris. Neither the an- 

 tenna of the male of alfkeni or saussurei is like that of Masaris, but 

 alfkeni is probably more like it than that of saussurei, the ocelli of the 

 male of Masaris are close to the eyes, those of both saussurei and 

 alfkeni much more distant, this character being due to the much closer 

 approach of the eyes to each other on the vertex in Masaris; the post- 

 seutellum of Masaris is not covered by the scutellum, and is bifid, while 

 in both saussurei and alfkeni it is entirely covered by the scutellum 

 and rounded, and finally, the subalate lateral angles of the propodeum 

 are of a very different type from that which obtains in both alfkeni 

 and saussurei. 



It is probable that the other South African species now placed in 

 Masaris will go in Masariella also, but as I have not seen specimens I 

 cannot say. It is further probable that after the species have been 

 thus studied it may become desirable to erect a separate subgenus for 

 saussurei and probably others on the basis of the difference in the 

 antennae and seventh ventral segment of the male.
