 EEMARKS ON INDIAN PSYLLID^.

Unlike other minor groups of insects it is gratifying to note that 

 the group of jumping plant-lice or Psj'llidse has been studied to some 

 extent in India. The previous records are chiefly by Buckton and 

 Kieffer and latterly by Dr. Crawford. I am sorry I have not been able 

 to see KielTer's " Monograph of Gall-making Psyllids " published 

 in the Annah of the Brussels Entomological Society in 1905, which would 

 certainly have helped in preparing this note, and also given us infor- 

 mation as to whether these galls are recorded by him. The early records 

 of Indian Psyllids to which we have easy access are in the pages of 

 Indian Museum Notes by Buckton and latterly in the pages of the 

 Records of the Indian Museum by Crawford. 



The following species have so far been noted : — 



(1) Psylla cistellata, Buckt., on mango shoots; Dehra Dun (7. 



M. N. Ill, 1, p. 13). 



(2) Pemphigus cedificatar,Bnc'kt. , onPistacia terebinthus ; Baluchis- 



tan {I.M.N. Ill, 1, p. 71). 



(3) Phacopteron lentiginosum, Buckt., on Ganiga finnata ; Poona 



and Dehra Dun (I.M.N. Ill, 5, pp. 18-19). 



(4) Psylla obsoleta, Buckt., on Diospyros melanoxylon ; Bombay 



{I.M.N. V, 2, p. 35). 

 In Lefroy's Indian -Insect Life, Plate LXXX, we have figures of 

 two other undesciibed species making galls on Alstonia scholaris and 

 Ficus glomerata. There is another species. of Psyllid we have in Coim- 

 batore, a pretty bad pest of a species of garden Cardia ; it does not 

 however make any jKominent gall-like structure on the plant. This 

 Crawford has named Ewphalerus cifri (probably it is the same as found 

 on C^Vrws jDlants elsewhere). 



The two kinds of galls just before you are : — 

 (1) That of Phacofteron lentiginosum on Ganiga pinnata from 

 pepper gardens in North Malabar. As you see, the leaves 

 are very badly galled and in the worst cases the plants 

 show nothing but these cylindrical, ovoid or finger-like 

 galls which often give the appearance of a cluster of
