 BY G. B. BUCKTON, f.r.s., etc. 

 I. Chaitophoriis maculatus^ n. sp. 



Plate No, XVII {fig. i). 



Head and pronotum honey-yellow ; front broad between the eyes and 

 bristly, eyes large and red. Body pink or yellowish, tuberculose, and 

 furnished with capitate hairs. Nectaries short and hardly visible, tail blunt. 

 The upper-side garnished with numerous brown spots disposed in vertical rows 

 down the dorsum. Antennae about the length of the body. Legs honey- 

 yellow, hind and front femora rather dilated. The sides of the thorax in some 

 specimens are swollen. 



The wings are short, rounded at the tips, and veined as in Chaitophorus, 

 The stigma is large and punctured, nervures slightly clouded at their termi- 

 nations. 



Size of apterous female z'o millemetres. 

 Infests Medicago saliva in Jodhpur, India. 



2. A NEW ROOT-FEEDING APHIS. 

 Uliifiobius jujuhce n. sp. 



Plate No. XVII {Jig. 2). 



Burmeister formed the genus Rhizobius to include certain aphides having 

 subterranean habits, and amongst other characteristics seemed to be apterous 

 in all their metamorphoses. Since his day Lechtenstein and others have 

 conclusively shown that many insects of this family have both serial and 

 under-ground habits as illustrated by Aphis subterranea and the destructive 

 Phylloxera vasialrix of Europe and America. 



1 Specimens were forwarded to the Indian Museum in March 1897 by the Superintendent 

 of Forests, Marwar, as destructive to lucerne grass {Idedicago saliva) in Jodhpur, E. B.
