 We might then hope for some good result. I might multiply 

 instances ; but, to confine the question to one point now, Mr. 

 Koebele should never have been allowed to leave New Zea- 

 land without making arrangements for further supplies of 

 insect friends to man. He showed by his first consignment 

 that the thing is possible. Had there been here an expert 

 scientist managing a proper department, he would have seen 

 the full value of the experiment, and would have taken care 

 to have it repeated. Our debt to our American friends is, as 

 I said, large ; the lesson they have tried to teach us is a good 

 one : all that we want is some man of common-sense and right 

 feeling to acquit the first and learn the second. 



This is a matter on which, as this Society knows, I have 

 for a long time endeavoured to induce the rulers of the colony 

 to be reasonable, and to establish a properly-equipped Agricul- 

 tural Department (or " Bureau," if the term is preferred), under 

 the charge of a properly-qualified scientific expert. Constant 

 dropping of water, they say, will in time wear away a stone. 

 Let me still hope for final success at some future time. 



I have also to record my thanks to Messrs. French, Olliff, 

 and Tepper for their Australian insects ; to Mr. Cotes for those 

 from India ; and to Messrs. Douglas, Cockerell, and others for 

 help, and specimens from different countries. Lastly, I must 

 acknowledge the very friendly terms in which many cor- 

 respondents have referred to the work on Homoptera con- 

 tained in my papers of the last fifteen years. 



Group DIASPIDINiE. 

 Genus Aspidiotus, Bouche. 



Aspidiotus cladii, Maskell. N.Z. Trans., vol. xxiii., 1890, 



p. 3. 



This species has been sent to me by Mr. Koebele from 

 Semaphore, South Australia, on Lejndosjwma. The speci- 

 mens are much finer, larger, and darker-coloured than those 

 originally described by me from Victoria, but I cannot other- 

 wise separate them. 



Aspidiotus acacias, Morgan. Ent. Mo. Mag., Aug., 1889, 



p. 353. 



Mr. Koebele has sent me specimens which are so near to 

 this species that I will not separate them : they occur on 

 Eucalyptus sp. at Whitton, New South Wales. 



Aspidiotus acaciae, Morgan, var. propinqua. 



On Acacia sp. at Mount Victoria, New South Wales, occurs 

 an insect very near to A. acacia, differing only in the deeper
