[.ACE WINGS CAN BE ACCMMATLSKI) IN NEW ZEALAND. (Special to the Herald.) CHRISTCHURCH, this clay. Experiments conducted by Mr. A. Ton. noir. entomologist at the Canterbury Museum, show that the green lace wing, introduced to New Zealand from British Columbia, to deal with the green aphis on oaks, can be at least acclimatised in New Zealand. Whether or not they will check the aphis will be disclosed when the experiments ha.ve advanced a stage. About 6CO perfect lace wings .sent to Mr. Tonne,ir lyy Dr. Tijlyard, chief hiolo‘gist of the Cawthorn Institute, Nelson, have been held captives in bags tied to infected twigs of oaks in the Museum grounds in North Hagley Park, and in Mr. .1. R. Montgomery's garden, Carlton road. Feudal ton. In a vivarium at the Museum some of the insects have laid many eggs. These are very small, ovAl. and like the perfect insects, light green. It is on the larvae or grubs that entomologists rely for help in, the war against the a,plii.s. 'l'he perfect insects are pretty little o'vikircs; their laeo-like wings are diarlianou.s, but tlieir greatest beauty is in their eyes, which are golden, a charac-

ter that inis earned for them an appro nriate entomological name. “Chagsopa" (golden eyes).
