The usual treatments against Clysia anihigudla and Polychrosis 

 hotrava are reviewed, and descriptions are given with illustrations of 

 suitable implements for the various processes advocated for scraping, 

 brushing, etc. of the bark.

The dates for dusting with quick lime against the vine moths [Clysia 

 amhigueUa and Polychrosis hotrana] [R.A.E., A, vii, 46] should be 

 regulated by those of emergence of the young larvae in the district 

 under observation. 



Owing to the abundance of Sparganothis pilleriana, 1 lb. of lead 

 arsenate dissolved in water was added to every 9 gals, of Bordeaux 

 mixture used for spring spra^ang. This treatment was repeated at an 

 interval of ten days, after which no larvae were seen and no scorching 

 was noticed.

The larvae of Sparganothis pilleriana, Polychrosis hotrana, the 

 poplar sawfly and Aphids on Japanese spindlewood [Enonymus'] 

 were used in the experiments here described. From 10 to 20 parts 

 per 1000 of chloropicrin were found sufficient to kill all larvae and 

 Aphids after an exposure of from 5 to 10 minutes. Used at half this 

 strength it proved equally efifective against the larvae, all of which 

 died within 24 to 48 hours after exposure.

The Longicorn, Cyrtognathus fornicatiis, L., has been recorded as 

 attacking vines in Morocco during 1918. The injury is caused by 

 the larvae attacking the roots two or three inches below the surface 

 of the ground, and they are able to cut through vines of a diameter 

 of ? to I of an inch. The adults appear in July, but are seldom seen. 

 The native food-plant of this beetle is a dwarf palm, and it probably 

 {ittacks vines only when there is a scarcity of this plant.
