NOTES AND EXHIBITS. 117 



Mr. T. Steel exhibited specimens of one of the common small 

 clay-nest-building wasps, Alastor erinrgus Sauss., from Brisbane, 

 together with the brood-nests which the insect had constructed 

 out of the gum of the Mango tree instead of the usual clay. 

 When gathered, the gum is soft and plastic, but, after a time, 

 becomes exceedingly hard and tough, with the result that when 

 the wasps emerge from the pupae they are unable to cut their way 

 out of the gum-cells and so perish. Numbers of dead wasps were 

 to be found within the gum-cells. 



Mr. R H. Cambage exiiibited, for Mr. J. H. Maiden, portion 

 of a flowering branch of Eucalyptus leucoxylon, F.v.M., collected 

 by Mr. Osborne Wilshire, at Deniliquin, where it is locally 

 known as " Bastard Gum." This is the common " Blue Gum " 

 of South Australia, and the " Blue Gum " or " White Ironbark " 

 of Victoria; but the first occasion on which it has been recorded 

 for New South Wales. Of course E. sideroxylon A. Cunn., 

 erroneously included by Mueller under E. leacoxylon^ is common 

 enough in New South Wales. 



Mr. T. Harvey Johnston recorded the occurrence in New 

 South Wales, of the following Entozoa, specimens of which were 

 exhibited : — (1) Tcmiia solium Linn., from man, a very rare 

 parasite in Australia, this being the first recorded occurrence. 



(2) Its cj'stic stage, Cysticercus cellulosce Kud., encysted in the 

 muscle of a pig, this being the first Australian record of it. 



(3) Tcenia saginata Goeze {T. mediocanellata Kchm.), the 

 unarmed human parasite which is rather uncommon; this is the 

 first record for New South Wales, and the second for Australia. 



(4) Dibothriocephalus latus (Linn.), also from man, this consti- 

 tuting the only Australian record of a tapeworm commonly met 

 with near the Baltic Sea; probably taken from a foreigner who 

 contracted it elsewhere. (5) Moniezia alba Perr,, from the 

 intestine of sheep in the New England district; it has not been 

 noted before from Australia. (6) Schistosomum hctunatobium 

 Bilharz, the ova of which were taken in Sydney from a returned 

 South African Soldier; this trematode has been recorded twice
