NOTES AND SYNONYMY OF HYMENOPTERA IN THE 
COLLECTION OF THE TRANSVAAL MUSEUM, 
By Dr. H. BRAUNS. 
The following paper deals with some types of the late Peter Cameron, 
collected mainly by Mr. Janse and described in the Annals of the Transvaal 
Museum. Only a part of the species described is at present in the Transvaal 
Museum. Descriptions by the same author on South African Hymen optera 
are to be found in the Transactions of the Philosophical Society of South 
Africa (now Royal Society), the Annals of the South African Museum, and 
in the Records of the Albany Museum, Grahams town. The large quantity 
of Hymenoptera from all parts of the world acquired by the late P. Cameron 
is now the property of the British Museum and contains some 2000 type 
specimens. The descriptions of these types are scattered over the whole 
world in various publications. Unluckily the majority of all these types 
are not valid, having been based on already known and described species. 
The late Geoffrey Meade Waldo, R. E. Turner, and Claude Morley have 
already studied a part of the type material deposited in the British Museum. 
The results of their study is to be found in the Annals and Magazine of 
Natural History, Ser. 8, Vols. XIV and XVI. I have myself published 
notes on synonymy of Cameron’s types in the Deutsche Ent. Zeitschrift 
and in the Revue Zool. Africaine. The synonymy could not be established 
in all the species before me. It will be necessary to study such material 
again when monographs of difficult genera are available, which is at present 
not the case. Up to that time such types have to be considered as valid. 
The material before me is in a very bad state of preservation. The types 
of the very small Braconidae, Ichnenmonidae, and Chalcididae cannot be 
recognized any more and should be discarded. They will be a ballast 
only in the literature. I have indicated such species , with an asterisk. 
1. Plesia transvaalensis Cam. <J Type. Annals of the Transvaal 
Museum, Nov., 1910, p. 119. 
This is not a Plesia , but a $ of Myzine. Cameron could not 
distinguish between the of Plesia and Myzine and committed 
many errors in his descriptions as pointed out by Turner in his paper, 
“Notes on the Scoliidae” — Trans. Ent. Soc., London, Dec. 21, 1910, 
p. 392. 
2. Plesia pacificatrix Cam. Type. Ibidem , p. 118. 
As the preceding species, this is not a Plesia but Myzine (J. 
3. Discolia pallidipilo sella Cam. $ Type. Ibidem, p. 120. 
This specimen is the <$ of Discolia Wahlbergi Sauss., and 
therefore synonymous with this species. 
4. Dielis transvaalensis Cam. £ Type. Ibidem, p. 121. 
This specimen is Elis barbata Sauss. ? and synonymous to 
the latter.
