the bamboo at Dehia, covering the foliage of the plants with its sooty- 

 black excretion, thereby doing- some injury. 



The winged female and the (apterous?) male are undescribed. 



The general appearance of this insect may suggest some affinities both 

 with the genus Lachnus and the genus Chaitophorus ; but the small 

 size of the insect, the short legs, the peculiar front, and the position of 

 the very short rostrum will eliminate it from the first genus, whilst the 

 non-tuberculose and slightly hirsute characters of the abdomen, etc.. will 

 separate it from the latter. 



An examination of the winged insect will be interesting, and show 

 the group to which this aphis should be referred.
