GOOSEBERRIES ENEMIES. 225 



diffused, are not very common. Nemafcus appendiculatus and N. consobrinus larvae 

 are troublesome in some years on gooseberry and currant bushes, and both are green 

 in colour. The former species has a black abdomen in the saw-fly, and is the smallest. 

 The latter is also smaller and duller in colour than N. ribesi, and there is only one brood 

 of caterpillars in a season, these passing into the ground to pupate : they are easily 

 cleared away in winter as advised for N. ribesi. 



Red Spider. This pest (Bryobia (Acarus) speciosa) sometimes appears on gooseberry 

 leaves in dry weather during April, and loses no opportunity of preying on the trees 

 during the season. Syringing thoroughly with bisulphide of calcium (Vol. I., page 

 248) or lime-water (Vol. I., page 260), and repeating a few times, is a simple, safe, and 

 efficient remedy, but feeding the roots with water or liquid manure and mulchings is 

 also necessary in dry seasons and in hot soils.
