11. South African and Aiistralian Aculeate Hymenoptera 

 in the Oxford Miisenm. By the late Col. C. T. 

 Bingham, F.Z.S. 



[Read May 3id, 1911.] 



The following paper forms the concluding section of the 

 lamented author's memoir published in these Transactions 

 for 1911 (No. XXII, p. 528). When the proofs of this 

 memoir were received from the printers, it was realised 

 that the concluding portion was wanting. Publication 

 could not well be delayed, and the paper appeared with 

 the introductory note adjusted to suit the circumstances. 

 The missing manuscript — mislaid as the result of a curious 

 accident — having been lately recovered, it is obviously de- 

 sirable that the memoir should be completed as soon as 

 possible, and that its second part should appear in as close 

 proximity as possible to the first. 



The following paper contains the description of one 

 Aculeate captured by Dr. F. A. Dixey, and four by Dr. 

 G. B. Longstaff, in South Africa in 1905. It also includes 

 descriptions of five Australian Aculeates in the Hope 

 Collection. I had long been interested in the peculiar 

 types of synaposematic pattern found in all large groups 

 of Australian Aculeates, and reproduced in many non- 

 Hymenopterous mimics. Col. Bingham very kindly deter- 

 mined the species in an illustrative collection, and wrote 

 the following descriptions of those which were new to 

 science. 



The types of all descriptions are in the Hope Depart- 

 ment of the Oxford University Museum. 



In this, as in the first part of the memoir, I have acted 

 under the kind and skilled advice of Mr. Rowland E. 

 Turner.
