Gonodontis obliquaria, Moore, Lycia robustum, Butl., and Boarmia 

 selenaria, Hb. Other food-plants of these moths previously recorded 

 by other entomologists or from the author's own experiments are : — 

 For T. fuscaria : TJiea japonica, T. sasanqua, Acer palniatum, Pyrus 

 floribunda and Primus tomentosa. For B. theae : Primus communis. 

 For L. robustum : Eurya japonica, and Pyrus mains var. tomentosa. 

 For B. selenaria : Morus alba. Keys to the larvae and imagines are 

 appended. 



Preventive measures are also discussed. As the eggs are laid under 

 the bark of pine trees near the tea plantation, they should carefully 

 be searched for and collected. Spraying with a mixture of insect- 

 powder, soap and water, while the larvae are still young, is also 

 recommended.

Grape-vines in New Zealand are not greatly troubled by insect 

 pests. Phylloxera is confined to a few localities in the far north of the 

 Dominion, and need not be present there if the growers would take 

 advantage of the resistant grafted vines available from the horti- 

 cultural stations. Cryptoblabes gnidiella {Albinia wokiana) and 

 Thyridopteryx herrichi spin webs among the fruit and eat the stems 

 of the berries at the time when these are about half grown. The 

 remedy is a spray of 1| lb. arsenate of lead to 50 gals, water. Pseudo- 

 coccus (mealy bug), which is the most serious pest of vines cultivated 

 under glass, is not of much importance in vineyards, except where 

 there is a general neglect of pruning and cleaning ; in such cases the 

 best treatment is the removal of all rough, scaly bark after pruning, 

 and syringing with hot water.

San Jose scale [Aspidiotus perniciosus] is the most prolific and 

 destructive of all orchard insect pests, and, although easy to destroy, 

 is most difiicult to eradicate, as any small number of individuals that 

 escape spraying are sufficient to start a new infestation, which rapidly 

 attains the same extent as the previous one. If the scraping of trees 

 to remove rough bark was made compulsory, as it is in Tasmania for 

 the control of codling-moth [Cydia pomonella], it is probable that the 

 difficulties of eradication of this scale, which shelters under the bark, 

 would be greatly minimised. The greatest amount of damage to fruit- 

 trees is done from the time the sap ceases to flow until the scale becomes 

 dormant, which in a mild season is well into the winter. In order to
