REMARKS. 



This species was originally described by Douglas from material 

 collected at Alexandria (loc. cit.). It is very widely distributed in 

 Egypt, and in Cairo, Alexandria, and Suez, it is a decided pest. The 

 street trees of Cairo, many of which are species of Ficus, suffer every 

 year and in particular F. nitida and F. infectoria. Fortunately the 

 Ficus spp. are hardy trees, or the damage would be very much greater 

 than at present. Periodically the Cairo street trees are sprayed with 

 a jet of water, and this has a beneficial effect by washing away many 

 of the insects and thus keeping the attack within reasonable limits.

BIBLIOGRAPHY: Mask., N.Z. Trans., xi, p. 221 (1878). 



The adult female is ovoid and dark reddish, the colour being 

 somewhat obscured by white secretionary matter. The ovisac is 

 very characteristic, having a surface of closely matted fibres fluted 

 longitudinally ; it extends underneath the body of the insect, tilting 

 it forward on to its anterior margin, and beyond the posterior extremity 

 of the abdomen to a distance of about 4-5 millimetres. 



Length of adult female 5-6 millimetres. Breadth 3 -5-4-5 millimetres.

REMARKS. 



This species is very generally distributed in Egypt, but can hardly 

 be regarded as a pest. It is largely kept under control by certain 

 COCCINELLID^E. Lemon trees in Upper Egypt occasionally get a 

 heavy infestation.
