GEEEN BUG IN MYSORE . 7 



to be infected. The outbreak in Coorg was noticed 

 simultaneously, and in an article in tlie Planters' Chro- 

 nicle in June 1913, Anstead noted the fact that the area 

 of infestation in Coorg was greater than that in Mysore. 



Sources of Infection in Mysore. — Though the pest 

 broke out in the coffee estates only in 1913, it was in 

 existence in the State at least some years previous to 

 this date. The first reference to the scale in Mysore 

 occurs in the annual report of Dr. Lehmann, the Agri- 

 cultural Chemist, for the year 1901-02.^ Specimens of 

 a scale had been received early in the year from an estate 

 near Santaveri. These had been forwarded to Mr. L. de 

 Niceville, Entomologist to the Government of India, who 

 identified them as L. viride (C. viridis). This identifica- 

 tion was wrong, however, even though in his letter to Dr. 

 Lehmann he went so far as to point out that " the mealy 

 bug appearance of the insect is caused by a white mould 

 and is not secreted by the insect itself." In giving this 

 caution, Mr. L. de Niceville had evidently in mind 

 the distinction between green bug and the mealy bug. 

 Nevertheless, the identification was wrong for, in Dr. 

 Lehmann's report of the year 1903-04,'^ this pest is referred 

 to as the green mealy scale and not as green bug. In 

 the interval between the two reports, Lefroy, Imperial 

 Entomologist, had visited the estate near Santaveri and 

 identified the pest as Pulvinaria psidii. There is practi- 

 cally no doubt that the latter identification was the correct 

 one. 



A still later but now correct reference to L. viride oc- 

 curs in the Planters' Chronicle of the 21st December 

 1912. It had been brought to notice at the annual meeting 

 of the United Planters' Association of Southern India 

 that the gardens of the florists in Bangalore, and possibly 

 the Lal-Bagh also, were infected and that the pest had 

 been introduced into the Mudgere Taluk, in 191 J, on one 

 of the orange plants brought from Bangalore. To prevent 

 the Lal-Bagh acting as a distributing centre of the 

 scale, Mr. Anstead addressed the Superintendent on 

 the advisability of establishing a fumigatorium in the 

 Gardens and, in accordance with this suggestion, one was
