I am sending yon, nuder separate cover, a small pamphlet on ''The Enemies of the 

 Coffee Tree," compiled by the late Mr. J. Neitner. Since the pnblication of this paper 

 many new enemies have made their appearance, notably the Lecaniiim viride, which 

 has practically wiped out coffee cultivation in many districts. Its vigor, the rap- 

 idity with which it is projDagated have defied any remedial measures that we could 

 afford to apply, and consequently planters are everywhere turning their attention to 

 the cultivation of tea in the place of coffee. The tea plant also has many insect ene- 

 mies; but, from the method of cultivation, which allows of periodically pruning 

 down the bush, it is better able to withstand them. 



I have noted as enemies of the tea, several species of " Red Spider," Tetranychus 

 and allied genera. 



Lecanlum coffew and a species of Aspidiotus. (Fortunately the Lecaniiim viride does 

 not flourish on the te.a plant). 



Terines fatalis, which eats through the stem just below the surface of the ground. 



Several small Lepidoptera belonging to the Tortricidae. 



A boring larva, Zeuzera coffeiv. 



The larvjTB of A'/roiis consurrata and A. diffusa are very mischievous in nurseries of 

 young tea plants. 



There are numerous other caterpillars that feed upon the leaves of the tea, but 

 damage caused by them is so small as to be of no account. 



It may interest you to know that specimens of a Lecanium found by me on mango 

 leaves, and sent to Mr. J. W. Douglas, of London, have been identified by him as L. 

 acnmivatum, Signoret (Essai sur les Cochenilles, Annales de la Soc. Entom. France, 

 1873, p. 397, PL 12, fig. 1) described from specimens found on orchids in the Luxem- 

 bourg gardens in Paris. Mr. Douglas tells me he has lately received this same 

 Lecanium from Demerara, where it is found upon both mango trees and orchids. 



It has for some time seemed to us that the scale insects of the coffee 

 plant which do so much damage in Ceylon and other parts of British 

 India could be successfully treated with the remedies which we have 

 found in this country so valuable against the scale insects of the orange, 

 viz, the kerosene soap emulsions, and we hope soon to bring this before 

 the attention of the British Government. 



PLANTS INJURED BY CAPSUS QUADRIVITTATUS. 



Mr. Warren H. Manning, of Beading, Mass., sends the following list 

 of plants injured during 1888 in Brookline, Mass., by this plant-bug: 

 The following plants were injured considerably, many others slightly : 



Deutzia crenata, badly. 

 Galium boreale. 

 Heliotrope (garden), badly. 

 Lemon Geranium. 

 Valeriana officinalis, badly. 

 Tauacetum vulgare. 

 Aralia spinosa. 

 Acer Japonicum. 

 Lysimachia clethroides, badly. 

 Achillea sp. 



Ranunculus acris fl. pi. badly. 

 Phlox suffruticosa, not P. paniculata. 

 Hydrangea pan'culata grandiflora. 

 Hibiscus Syriacus. 

 Philadelphus coronarius aureus. 

 Lunaria rediviva, very badly. 

 Campanula persica? folia. 

 Polemoninm reptans. . 

 Hypericum perforatum, badly. 



This insect's impartiality is noticeable, taking, as it did, acrid, bitter, aromatic, 

 and sweet tasting leaves, and smooth or rough surfaces.
