5. Myzine immaculatus Cam. (sic!). § Type. Ibidem , p. 117. 
Should be immaculata ! 
6. Myzine erythrostomus Cam. (sic !). $ Type. Ibidem , p. 117. 
Should be erythrostoma ! and is synonymous to Myzine rufifrons.

Cameron, p. 150, marks his type “ male,” while the type 
specimen before me is a “ female.” The description of Cameron 
points to a $. He compares, p. 150, his C. Jansei with C. melanospila 
Cam. I have already, loc. aliis, stated that C. melanospila is 
synonymous to C. diodonta Schletterer, so is C. Jansei Cam. The 
specimen represents the form of diodonta Schlett. as it occurs in 
the north of South Africa. The synonymy must therefore be read 
thus : — 
Cerceris diodonta Schlett. 
C. melanospila Cam. 
C. Jansei Cam. 
9. Cerceris heterospila Cam. § Type. Ibidem , 150, p. 151. 
There -are three specimens, two of each labelled as “ Type of 
heterospila .” The third specimen is labelled as “ Type of heterospila 
Cam. var.” Two of them have the locality-label “ Doornfontein,” 
one only the number “ 4125.” All three specimens are while 
Cameron marks his type of heterospila as a $. Two of the specimens, 
viz., the one No. 4125 and the one labelled “ heterospila var.,” agree 
well with the description though the sex is wrong. The third does 
not belong to the described species, but is a small £ of Cerceris 
ventrilobata m.i.l., as I have it in my collection. It is at present not 
quite certain whether this m.i.l. name will be stable or prove to be 
synonymous with a previously described species. The two above 
mentioned must therefore at present be considered as the type and 
type var. or the species described as heterospila Cam. and “ female ” 
has to be altered into male ” in Cameron’s description.

This specimen is not collected by Janse and therefore not 
described with the other material in the Transvaal Museum Annals. 
Bearing the locality-label “ Pearston ” (Cape Colony) it is 
apparently a specimen collected by Dr. Broom at Pearston. 
Cameron described, loc. cit., some Hymenoptera collected by 
Prof. Dr. Broom at Pearston. The specimen before me is apparently 
the type of the description as cited above. Cameron omits in his
