82.— NOTES ON TWO PSYLLID GALLS EXHIBITED, WITH 

 EEMAEKS ON INDIAN PSYLLID.^.

 Entomologist, Madras.

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

 the group of jumping plant-lice or Psyllidae lias 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 Kieffer's " Monograph of Gall-making Psyllids " published 

 in the Annals of the Br^issels 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 Mxiseum by Crawford. 



The following species have so fax been noted : — 



(1) Psi/lla cislclkita, Buckt., on mango shoots ; Dehra Dun (7. 



M. N. Ill, 1, p. 1.3). 



(2) Petnphigns CEdificator,Jiut\s.t., oiiPistacia terebinthvs ; Baluchis- 



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



(3) Phacopteron lentiginosum , Buckt., on Ganiga pinnnta ; 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 undescribed species making galls on Alstonia scholaris and 

 Ficus glomerala. 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 prominent gall-like structiu-e on the jilant. This 

 Crawford has named Etiphaleriis cilri (probably it is the same as found 

 on Citrus plants elsewhere). 



The two kinds of galls just before you are : — 

 (1) That of PhacojAeron lentiginosmn on Garuga pinnata from 

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

 are very badly galled and in the worst cases the plantg 

 show nothing but these cylindrical, ovoid or iinger-lilce 

 galls which often give the appearance of a cluster of
