defines Mimecomutilla do not apply to purpurata Smith as described 

 by Bischoff who had for study a metatopotype of that species from 

 the British Muséum. Still différent from either purpurata Smith or 

 from Ashmead's interprétation thereof are spécimens which hâve 

 been identified by Péringuey and other South African entomo- 

 lists as purpurata and which hâve been made by Bischoff his species 

 renominanda. Bischoff called this the génotype of Mimecomutilla, 

 but was incorrect in doing so, since Ashmead had already established 

 purpurata Smith as génotype. Furthermore renominanda also does 

 not agrée with the characters assigned by Ashmead to Mimecomu- 

 tilla, since it possesses three distinct submarginal cells and Mime- 

 comutilla was characterized as having only two. 



According to Bischoff, and we hâve no occasion to disagree with 

 him, purpurata Smith is a true Mutilla. Mimecomutilla Ashmead based 

 on it as génotype (even if misidentified) must therefore be reduced 

 to a synonym of Mutilla. For the group which Bischoff calls Mime- 

 comutilla, typified by his renominanda, there seems to be no need to 

 find an applicable name, since we cannot find any characters by 

 which to recognize it as distinct from Smicromyrme. Spécimens of 

 both sexes of renominanda determined by Bischoff lie before us and 

 it is very vertain that there is no distinction in the shape of the maie 

 head, such as indicated by Bischoff in his key, between the majority 

 of the species of thèse groups although it is true that in rufipes Fa- 

 bricius) the type of Smicromyrme, the head is slightly prolonged ind 

 pointed medially. The weak différence in the sculpture of the pygi- 

 dial area in the female and the occasional différence in the macu- 

 lation of the second tergite of this sex cannot be looked upon by us 

 as substantiating generic or even significant group distinctions. 

 Furthermore, in the maies, rufipes and renominanda both agrée in 

 having externally dentate mandibles and there are groups of species 

 which Bischoff puts both in Mimecomutilla and in Smicromyrme 

 which possess mandibles unarmed externally. 



We hâve before us a maie of Lobotilla leucopyga var. leucospila 

 (Cameron) identified by Bischoff and other spécimens which agrée 

 with it. The clypeus is of the same type as in certain other species of 

 Trogaspidia, that is to say there is a superior raised area, a depres- 

 sed, transverse disk, and a narrow, anterior, transverse area. But,
