area ; it is hoped that sufficient insecticides will soon be received to 

 deal successfully with this outbreak. Olive trees in Malaga are 

 attacked by various pests, including Phheotribus scarabaeoides (oleae) 

 and Saissetia oleae.

The formula here recommended against cutworms has aheady 

 been given [see this Review, Ser. A, vii, p. 262]. The substitution of 

 9 oz. of white arsenic for 1 lb. of Paris green has been suggested ; 

 six lemons or oranges chopped finely and added to the mixture increase 

 its attractiveness for cutworms. Maize tops, potato haulms, turnip 

 tops etc. soaked for about 5 minutes in 1 lb. of Paris green to 10 gals, 

 water, have proved successful as baits in South Africa. 



The following additional maize pests [see this Review, Ser. A, vii, 

 p. 84] are recorded. Euxoa {Agrotis) radians, Gi.cn., also occurriug on 

 lucerne, vegetables, and other crops ; Prodenia litura, F., attacking all 

 the above as well as weeds and Lantana ; and the pumpkin beetle, 

 Aidacophora olivieri, which attacks the leaves and silks of maize. 

 In the north coast river districts one of the most serious pests is a 

 Chrysomelid, Monolejjta rosae, Blackb., which attacks the silk of the 

 maize cob as well as citrus and many other fruits of which the blooms 

 and young foliage are injured. During the winter these beetles have 

 been known to swarm on Acacia spp. The pepper tree is attacked 

 both in winter and summer. A list is given of dates of appearances 

 on different food-plants from March 1918 to February 1919. 



Various remedial measures have been tried and so far as the present 

 experiments go, a spray that quickly dislodges the beetles and enables 

 them to be further sprayed on the ground seems likely to be the 

 most satisfactory.

The caterpillars of a Lithosiid, Nola metallopa, are reported to have 

 been causing severe damage to Eucalyptus rostrata. They feed on 

 the green leaves and cause withering of the branches and twigs. A 

 description is given of the various stages.

In AustraUa the gregarious larvae of several species of the genus 

 Perga are common at certain seasons, especially March and April, 

 feeding on the foliage of young Eucalyptus trees, but the perfect 

 iusects are comparatively rare, since the larvae are attacked by 

 many Dipterous and Hymenopterous parasites. Perga dorsalis, 

 Leach, has an extended range round the coast and is common in 

 Victoria and New South Wales. The gregarious larvae feed at night 

 and rest during the day, those that pupate in the soil in the middle 

 of April having been found to produce adults ia the early part of
