The geographical range of the pest under consideration is extensive. 

 It is found in the Isle of France and in Madagascar, and it would be 

 interesting to learn something about its ravages, and to ascertain when 

 it was first observed, how supposed to be introduced, etc.. in the islands 

 named. It does not yet affect all the mango-producing districts of India, 

 but its march is progressive. Restricted apparently at one time to Dacca 

 and the Southeastern districts, Backergunge. Furridpore, etc., I learn it is 

 working its way westward and northward, and throughout Bengal and 

 the neighboring districts. An article on the subject will be found at 

 page 558 of Rets and Rayyet for 1885, in which we are told that this 

 insect-pest has invaded the Presidency, and that in the season of 1885 it 

 showed itself in the well kept orchard of Kaly Kissen Tagore. I learn 

 from a gentleman residing in Ballygunge that every tree in his garden is 

 infected. Rcis and Rayyet also informs us that Slyhet was formerly 

 practically tree from this circulio, two or three mangoes per 1,000 alone 

 being tainted. During the last few years the pest has gained ground so 

 rapidly in Sylhet that now not a single tree nor fruit is free. 



ITS INTRODUCTION 



The mango weevil is not recorded by Dr. R. C. L. Perkins in 

 that part of Fauna Hawaiiensis, published in 1900, dealing with 

 the family of beetles to which this species belongs. As the col- 

 lection of the species therein recorded by Dr. Perkins ceased 

 some two years previous to the above date, it is almost certain 

 that the weevil of the mango has been introduced since 1898. It 

 came from India, or possibly the Philippines, if it occurs in the 

 latter country, since mangoes have been shipped to Hawaii from 

 both places. The beetle was introduced either during the de- 

 velopmental period in the seeds or in the hibernated state in the 

 soil about plants from the infested countries, or possibly even in 

 packing or crevices of boxes containing plants. 



ITS OCCURRENCE IN HAWAII 



The mango weevil is first recorded from the Hawaiian Islands 

 by the writer in August, 1905. 1 The first specimen observed was

 lulu, 1005, pp. 231-233.
