of species found in all the genera except one, namely, the genus 

 ■Ceraphron. The genus Ceraphron will now contain over forty 

 Australian species, that number being nearly three-fourths 

 of the total number of Australian species in the whole family. 

 Of the species described herewith, twelve were received from 

 the South Australian Museum, the remainder being taken by 

 Mr. A. A. Girault and myself in North Queensland. Only 

 one species, Aphanogmus braconis, Dodd, has been bred. 



The types are all in the collection of the South Australian 

 Museum. 



The magnification used was f-in. objective, 1-in. optic,
