Appendix. 189 



X. AsteroUcanium hambusae, Boisduval ; Insectologie Agricole (1869). 



Specimens sent by Mr. Fletclier from Egypt on Bamhusa arundinacea. 

 Mr. Newstead says it is common at Assouan on Bambusa sp. He also 

 gives the following localities elsewhere : Algeria, West Indies, Brazil, 

 Ceylon, Britain (" Cocc. Brit. Isles," ii., p. 153), and now adds as additional 

 localities Grenada and Mauritius. Its habitat seems to be the various 

 species of bamboo. Their presence on the leaves is marked by yellow 

 stains. 



XI. Icerya seyyptica, Douglas ( = Crossotosoma aegypticum, Douglas). 



The so-called Fluted Scale is most harmful in Egypt, feeding upon 

 banyan, fig, orange, and many other trees. At Alexandria it infested most 

 of the gardens and killed the trees right off in 18S9 and 1890. It is also 

 known as the Egyptian Mealy Bug. Cairo has also suffered from this 

 pest. 



This pest also occurs in India, where it is much parasitised, and hence 

 possibly indigenous to that continent. It also occurs in Australia, where 

 it has been found at Sydney on Goodenia ovata. The white waxy excretions 

 of this species are absolutely pure wax, and as the excretions readily fall 

 without the insects, it has been suggested that this wax might be used for 

 economic pui*poses such as making line wax candles (" Insect Life," iii., 

 p. -I:24). This wax is said to be quite as fine as the white Chinese wax 

 secreted by Ericeruspe-la, which lives on the so-called Insect Tree, Lkjuatrum 

 lucidum. The white wax industry of the Plain of Chien-Chang is .described 

 in " Garden and Forest " for January 28, 1891. 



XII. Dactylopius sp ? 



A specimen was sent by Mr. Fletcher too imperfect to identify, but is 

 thought by Mr. Newstead to be probably a species of Dactylopius.
