326 PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



Of mealy-wings we have chiefly the Dialetirodes eugenice on Eugenia 

 and Aleiirodids on Bassia and Citrus. 



Of plant-lice pests we have several, and of these the chief are those 

 found on cotton, tobacco, Citrvs, lab lab, cow-pea and cJioJam. 



Bamboo VVoolly Aphis. On bamboo we occasionally find a species 

 of wnolly a^ihis coming in large colonies (PI. 19, fig. 2). It is not the 

 same as Fletcher's fig. 392. 



The Coconut Aphis (Cerataphis latanice), Fletcher's fig. 393, has not 

 been noted since. 



Coming to Scales and Mealy-bugs there are a good many species of 

 importance. In a paper I prepared for the Session of the Inchan Science 

 Congress held at Lahore in 1918, I hsted 32 species of Coccids having 

 some economic importance. Though all these are not had pests at 

 present, some of them are really important. Of these mention might 

 be made here of the following. 



Pidvinaria maxima, Gr., a bad pest of nim trees (Melia azadirachta). 



Ceroplastodes cajani, on lab lab stems and Ocimum ; often bad. 



Anomalococcvs indica, Gr., on bahil (Acacia arabica). 



Pseiidococcvs sacchari. Bad on paddy. The disease is called Scorai 

 now in Tamil and often reported from Tanjore, Trichinopoly and Madura 

 districts. Fields badly attacked show the infestation patches here and 

 there. 



Phenacoccvs insolihis. Bad on brinjal plants, Madras, Coimbatore, etc. 



Rifersia sacchari. On sugarcane stems. This is the commonest 

 species of mealy-bug on cane, and is different from Psendococciis sacchari. 



Icerya cegyptiaca. On jak, Malabar and Nilgiris. This is the species- 

 to which I referred at the last meeting (p. 152 of Eeport). 



Hemichionaspis aspidistrce. On pepper in Malabar, and also on 

 Ficus leaves elsewhere. 



Aspidiohis tamarindi. On tamarind. Coimbatore etc. 



Phenacoccvs iceryoides. On mango ; in Coimbatore. Northern Circars- 

 and Tanjore. 



Pseiidococcvs corymbatvs. On cotton, mango and jak. In different 

 places. 



Aspidiohis avrantii. On rose, Malabar. 



Aspidiohis curcvmce or harhi. On turmeric rhizomes at Coimbatore-. 



Pseudococcvs lotigispinvs ? Bad in,side leaf-sheaths of young coconut 

 trees ; Coimbatore, Malabar and South Kanara. 



Orthoptera. 



Among grasshoppers no new pest of any importance has been noted.. 

 The wingless grasshopper, Crthacris sp., was however found pretty ba<J
