Pseudococcus virgatus and another species — probably P. crotonis ; 

 Psychid caterpillars ; a Limacodid, Belippa lalcana ; and the coffee 

 weevil, Araecerus fasciculatus. 



Phaseohts lunatus was repeatedly attacked by Agromyza phaseoli, 

 some crops being destroyed. 



Maize pests included the caterpillars of Heliothis obsoleta {armigera), 

 Cirphis {Lcncania) iniipinida, and cutworms. 



Oil palms suffered from Oryctes rhinoceros, 0. tritnbercnlatus and 

 Rhynclwphoriis [ferriigineus]. The Lepidopterous pests of these palms 

 were M elissohlaptes rufovcnalis, Amathusia phidippus, Discophora 

 celinde, Setora nitens, and Psychids. The last-named did much damage 

 in some cases. 



A small plantation of Ricinus was defoliated b}' the Noctuid, 

 Achaea janata {Ophiusa melicerta). 



Rice pests included Nymphtda depunctalis, Schoenohins incertclhis 

 [hipunctifer) and Scirpophaga sericea ; Spodoptera maiiritia ; the bugs, 

 Leptocorisa acuta, Nezara viridula, and Podops vermicidata — of which 

 the last-named did considerable harm in Sumatra ; and Tetraneiira 

 oryzae ; as well as locusts, grasshoppers and crickets. 



Tobacco was attacked by the caterpillars of Heliothis, Phytometra 

 {Plusia) and Prodenia. Now that the accumulated stocks of baled 

 leaf have been shipped the infestation by Lasioderma serricorne and 

 Setomorpha margalaestriata is of less importance. 



Tea was attacked to some extent by the caterpillars of Attacus atlas, 

 Belippa laleana {Nemeta hohor), Acanthopsyche snelleni, Stauropiis 

 alternns, a large Liparid, Psychids, the Limacodids, Thosea cervina 

 and Setora nitens, and Andraca hipunctata. Hclopeltis theivora, 

 H. antonii, the Pentatomid bug, Cantheconidea rohusta, an unidentified 

 Capsid, Hyalopeplus smaragdimis, and the tea-seed bug, Poecilocoris 

 hardwicki, also infested tea, other pests of which were a Curculionid, 

 Corigetus scapularis, Coccids, Zenzera coffeae and other borers, and 

 the tea-seed fly, Adrama determinata. 



Mangos were extensively attacked by the mango fly, Dacus 

 ferrngineus.

The bulk of the information given here has already been noticed 

 [R.A.E., A, vii, 269, 518]. 



Great variations in size, shape and colour are met with in Xylotrechus 

 quadripes, Chevr., so that many species of this genus described from 

 the Far East may prove synonymous. X. sappho, Pasc, is considered 

 by Wallace a synonym of A', javanicus, Cast. & Gory, and the latter 

 will probabl}/ prove to be identical with A^. quadripes, Chevr., for 

 the specimens received b}' the author from Java are very similar to 

 the species found in Tonkin on Coffea arabica and, especially, on 

 C. liberie a. 



Very shady situations are distasteful to the females. This has been 

 clearly shown in the laboratory, and in plantations the least shaded 

 places appear to suffer most. 



Experiments to detennine the length of the life-cycle in Tonkin 

 are in progress ; in the case of eggs deposited on living coffee bushes
