ENEMIES. 



In studying the slides of the ^National Collection of Coccidse one 

 partially mature specimen of the parasite Aspidiotiphagus citrinus 

 Craw was discovered inclosed in the body of an adult insect collected 

 in Washington, D. C, on Chsemerops humuU and the same chalcid 

 has also been reared from material on Persea gratissima from Hono- 

 lulu, Hawaii. In addition to the above a species of Aspidiotiphagus 

 was reared from this scale on an unknown plant collected at Hong- 

 kong by Mr. Koebele, and he also collected Prospaltella aurantii 

 How. from this coccid on Ficus sp. at Swatow, Canton, China. 



Among the fungous enemies of this coccid the redheaded fungus 

 (Sphxrostilhe coccophila) has been recorded ' by Mi-. John Parkin 

 from Mauritius on infested Camellia.
