0\x'r twenty years ayo. when there was a threat made h\- the i'ro- 

 \incial Hoard of Horticulture to enforce the rei;nlatioii- and coinpel llie 

 people to spray for this scale, 1 pointed out then tliai tliere were several 

 other trees than those i^rowini^ in our orchards upon which the scale fed 

 and flourished. Since then 1 ha\e noticed many more, helon^iny to very 

 different natural orders.

We notice from this that we ha\e several different orders re|)re 

 sented. and 1 douht nut that there are many others that ha\-e not come 

 to in\- attention. I ha\e found the insect at sea le\cl up to an altitude 

 of not les> 'than 3,000 feet, 



llappily foi- us here the scale is e.Ntreiucly snl)ject to parasitism and 

 rejiroduces slowly, else with our henehcent climate it would he difficult 

 to kee]3 in check. 



Little more need be said. I should he pleased to hear from anyone 

 who has recorded thi.s scale on any other host plant than I ha\e men- 

 tioned. The life history is siin].)le and sin^^le brooded and outlined for 

 the Society in an article in our last annual Proceedings* by Mr. 

 Treherne.
