quadripustuhlus, L. The former inhabits the whole of Europe and 

 Northern Asia. In Italy it chiefly attacks Filippia oleae, Pollinia 

 polleni, Aspidiotus ostreaejormis {hetulae) and Aulacaspis {Diaspis) 

 pentagona. In Italy there are three generations a year. In Europe, 

 the insect is attacked by the Chalcidoid parasites, Homalotylus 

 jlaminius, Dalm., and Tetrastichus epilachnae, Giard. The eggs are 

 also destroyed by inites. 



E. quadripustulatus occurs throughout Europe and is similar in 

 habits to C. bipustulatus. Both species have been liberated in orchards 

 of lemon, orange, and olive trees, the citrus being infested with Coccus 

 citricola, Campb., and the olives with Saissetia oleae, Bern.

Paraleptomastix ahnormis, Gir., a Chalcidoid parasite of Pseudococcus 

 citri (mealy bug) has been successfully reared in California and liberated 

 in infested orchards. At San Diego, on trees which had been fumigated 

 two weeks before observations were made, the remains of mealy bugs 

 from which the parasites had issued, were found. This seems to show 

 that probably the full-fed larvae and the pupae, at least, are resistant 

 to hydrocyanic acid gas. Its apparent resistance to fumigation and 

 the aversion shown by predaceous Coccinellids for mealy bugs para- 

 sitised by it, after a certain stage of development is reached, renders 

 this insect especially suitable under California conditions.
