There are but few insect enemies of the vine in Tunisia. The 

 principal ones are a scale, Pseudococcus vitis ; a mite, Eriojphyes vitis ; 

 Anomala vitis ; Agrotis pronuba ; and Rhizotrogus sp. Up to the present 

 the Pyralid, Sparganothis pilleriana, and the vine-moths, Clysia 

 amhiguella and Polychrosis botrana, have not been recorded. Phylloxera 

 was first observed in 1906. Most of the vines attacked no longer 

 exist, having been destroyed by the authorities. At present only one 

 vineyard is known to be infested, and as it happens to be in an isolated 

 situation there is little danger of the spread of this pest.

A brief account is given of a Lepidopterous pest of spineless cactus, 

 'described by Brethes as Neopyralis ronnai, gen. et sp. n. The author 

 noticed the infestation in an imported cactus and succeeded in breeding 

 the adult moths. The female lays several eggs on each cactus stem, 

 and the larvae feed voraciously and easily pass from one stem to 

 another, causing severe injury. They are polyphagous — at least as 

 regards the various species of cactus.

One of the less known pests of tea is the Capsid bug, Hyalopeplus 



smaragdinus, Rpk., which is closely allied to Helopeltis, though very 



far from being as dangerous. 



The imago, larva and egg are described. Little is known of the life- 

 history. In the laboratory at Buitenzorg the larvae moulted six 

 times before attaining full-growth in 9-10 days. The young larvae 

 lemain motionless on the tea buds. The unago is restless and flies
