YII. Ceroplastes africanus. Green, on Acacia (ex-collection Brit. Museum). 



These specimens are undoubtedly referable to Ceroplastes africanus. 

 Green [Ann. and Mag. Nat. Hist., ser. 7, vol. iv., p. 188. Types Coll. 

 Brit. Mus.]. In drawing up his diagnosis of this species (I.e. p. 190), Mr. 

 Green refers to the examples from Egypt, and says that they agree with 

 those from the Cape in general appearance and structure, including the 

 characters of the anal tubercle and stigmatic clefts. But as he was unable 

 to make a critical examination of the antennte, he could not decide. 

 Examples with perfect antennae have now been examined, and as the 

 structural details of these organs are found to agree with Mr. Green's 

 ample description, there can be no further doubt as to their identity with 

 the types from Cape Colony. 



It is evidently a not uncommon species in Egypt, as Newstead has 

 received it in some numbers from Luxor on young branches of Acacia 

 nilotica, and also from Cairo and Assouan on the same plant or a species 

 closely allied to it. The specimens from the first-named locality were 

 collected in 1899 by Prof. Schweinfurth, the others by Dr. L. A. Jagers- 

 kiold. The cereous test or covering in all the examples are in an imperfect 

 condition, and may be slightly " weathered," having lost all trace of the 

 sculpture noted by Mr. Green in his types. The most salient character, 

 and one by which it may readily be distinguished from all other known 

 species of the genus, is the strongly defined cephalic extension, or " trowel- 

 shaped projection," in which respect it closely resembles the $ of Vinsoiiia 

 sfrllifpra, Westw.

The outline of the puparium of the female is nearly circular, with a 

 slight inclination to be triangular. Fresli examples are described as being 

 greenish-yellow in colour, with a sparse covering on the dorsum and a 

 fringe of pinkish hair-like rods of secretion. It infests a number of plants, 

 upon which it produces pustules or swellings. It is most destructive to the 

 fig and oleander, but is said to be rarely so on other plants. It is a pest in 

 the West Indies, and is found also in Brazil, Mexico, Florida, California, 

 S. Carolina, Antigua, Trinidad, Australia, New Zealand, and in France. 

 Mr, Maxwell Lefroy * says that " it is a curiously destructive species, a 

 few only being sometimes sufficient to kill a twig or small branch. A 

 small pustule is formed below the insect, suggesting the injection by the 

 insect of some poison which not only leads to the formation of the pustule, 

 but to the speedier death of the infested twig, leaf or stalk." As a remedy 

 he suggests the use of the kerosine emulsion. 



Mr. Fletcher sent this species from Egypt on Ficus sycomorus and Ficus 

 cardica. They also attack Pelagonivms and other ornamental plants in 

 Egypt, writes Mr. Fletcher.
