olive fly, Dacus oleae, which so severely infested the trees in 1916 

 that in some localities the crop had to be gathered unripe. Ceratitis 

 capitata, Wied., which is now endemic, infests many fruits such as 

 oranges, mandarines, persimmon, etc. 



A useful insect that gives rise to the gall so much sought after in 

 Morocco for the preparation of leather, has now been determined as 

 a species of Erioj)hyes \E. tlaiae] [see this Revieiv, Ser. A, v, pp. 191, 

 291]. In any case, the planting of tamarisk is only advantageous if 

 the insect is imported with the plant, which has not always been the 

 case.

 with the rice weevil [Calandra oryzae] and Tenebroides mauritanicus

 ants being found in a crate of vegetables ; the peach moth on peaches
