No. 33. Vitcx hctcrophylla ROXB. 



A leafgall caused by a gallmite. 



On either surface of the leaf are developed round granular patches 

 of a bright white colour. Average size about 3 mm. On the reverse side 

 the galls are hardly discernable. The gallgrowth consists of peculiarly 

 formed hairs, which are clubshaped and multicellular.

No. 34. Rubiacea. 



On a shrub which was flowering belonging to the above mentioned 

 family, I found a gall caused by a gall-mite. It seems better to leave the 

 détermination of this gall to another scientist, who collects material in 

 Hongkong. Descriptions of galls on plants which hâve not been deter- 

 mined are of no use, if they hâve no striking features, which is true in 

 this case.
