A new Cecidomyid, Coccodiplosis pseudococciy gen. et sp. n., is here 

 described from Java. The larvae feed upon scale-insects, including 

 various species of Pseudococcvs, such as P. adonidum, P. citri, P. cro- 

 tonis, etc. Other new Diptera from Java include a Muscid, Pentato- 

 mophaga hicincta, gen. et sp. n., bred from the coffee bug, Pentaiomu 

 plebeia, Voll., and an Agromyzid, Agromyza tephrosiae, the larvae cf 

 which mine in the leaves of Tephrosia.

The Lycaenid, Gerydus boisduvali, Moore, has been observed in 

 Central Java attending colonies of the scale, Pseudococcus crotonis, 

 on cacao plants infested with the black cacao ant, Dolichoderus bituher- 

 culatus The butterfly strokes the scales with its proboscis and drinks 

 their secretions. The swarms of black ants in no way interfere with its 

 activities and they, in turn, are not disturbed by it. A number of 

 the Lycaenid pupae were found in an old nest of D. bituberculatus used 

 in cacao plantations to encourage this ant.
