No. 5.] Note on two new species of Aphids from India. 278 



But the life-history of these Rhizobiinj© is still obscure, and for a time it 

 will be well to retain the genus, as Kaltenbach has done. I now describe 

 an Aphis feeding in plenty on the roots of Zigyphiis jujubcB in the 

 neighbourhood of Kaladhugbi, India. They were collected some two or 

 three years ago by Mr. Octavius Greig. 



Rhizolius jujuboe n. sp. — Long, oval, hirsute, and of a rich brown 



colour; the smaller individuals being paler. Antennas very short, with 



five joints, the terminal joint being somewhat clavale and ending with two 

 setae. 



Eyes close to the insertion of the antennse, very small and not faceted. 

 Nectaries absent. Legs stout and short, tarsi with one claw only. Rostrum 

 reaching to the second coxae. 



The young are much smaller and are much more aphis-like in general 

 form. 



The companies were attended by ants, but for what purpose it is not clear, 

 since the Aphides do not possess nectaries to pour out " honey dew." 



Size 16 X 7 millemetres.
