is to keep the plants in a healthy vigorous condition by proper 

 manuring, proper tilling of the soil, and proper pruning. It 

 should be borne in mind also, that it is not the Coffee plant 

 which alone gives sustenance to the Bug; it will be found on 

 mostly all plants of the jungle, and especially those of a suc- 

 culent nature, which should be carefully removed from the 

 vicinity of a Plantation, 



The White Bug. 



There is a Coccus possessing similar characteristics with the 

 last described, but having gigantic proportions in comparison 

 with it ; it may be named the White Bug from its colour. 

 I found the first example I have seen upon a Bullock's 

 heart tree (Annona reticulata ) growing in a garden not far 

 from the Fort, and though there were but few of them to be 

 found on the tree, they have had the effect of retarding its 

 growth in a remarkable manner, and causing it to produce 

 very abortive fruit. Its outer surface is rather square shaped, 

 and instead of being smooth, like the last, it is ridged and 

 groved in a perpendicular direction :— on detaching one from 

 the branch, the same dust-like substance was scattered about, 

 which on examination proved to be the ova of the insect. It 

 is a fortunate circumstance that this insect is not so univer- 

 sally found as the former, as it appears to be much more in- 

 jurious to vegetation than the Coffee Bug. 



Cotton Aphis. 



The next insect I have to describe is the Cotton Aphis, 

 which appears to be altogether a different variety from the 

 other members of the same family, and not altogether confined 

 to the Cotton plant. 



I found an example on a Cotton plant growing in a very 

 confined locality and in an extremely rich soil; the accom- 

 panying engraving will explain the difference of appearance 

 between this and the last two insects. They are easily re- 

 cognised on the plant by the white wool like substance with 

 which they are covered, and on removing this, they are to
