thus become a synonym of Maskell's species under the name of R. poae. 

 Mytilapsis drimydis, Msk., is undoubtedly the second instar of a species 

 of Fiorinia, probably F. stricta, Msk., now placed in the genus Leucaspis 

 [see this Review, Ser. A, iv, p. 322]. A new Diaspidid is described 

 under the name of Odonaspis ! leptocarpi, sp. n., occurring on Lepto- 

 carpus sp.

This paper discusses the advisability of planting belts of trees of a 

 kind innnune from the attacks of the shot-hole borer of tea [Xyleborus 

 fornicatus] and the tea tortrix [Howona coffearia], such as Acacia 

 decurrens, between all tea-estates, as a means of checking further spread 

 of these and other pests [see this Review, Ser. A, v, p. 51]. These belts 

 should be 30 ft. wide, and should consist of closely-planted trees, 

 supplemented by a thick undergrowth. This would be a large under- 

 taking, involving considerable expense, but in the author's opinion is 

 well worth consideration,

The information contained in this report relating to insect pests of 

 tea, Hevea, coconuts and rice has already been abstracted [see this 

 Review, Ser. A, v, p. 51]. Pests of fruit and vegetables included the 

 Geometrid moth, Thalassodes quadraria, feeding on mango in AugiLst ; 

 the same plant was damaged by a leaf-miner and a leaf-roller in 

 September, and by the Chrvsomelid beetle Monolepta orientalis, Jac, 

 in October. The scale, Oudahlis solani, Green, infested egg-plants in 

 April, and the lace-wing bug, Urentius echinus, Dist., attacked them in 

 August ; a shoot-borer of the same plant appeared in December, but 

 could not be reared to maturity. It was probably the Pyralid, 

 Leucinodes orbonalis. A Lepidopterous borer of potatoes was reported 

 in September. An ant, Dorylus indicus, attacked rhubarb and turnips 

 in March. The caterpillars of Terias sUhetana defoHated Sesbania 

 grandiflo'ra in August. The larva of BelipjM laJeana appeared on 

 Gliricida maculata in September. The Capsid bug, Disphinctus 

 formosus, punctured guava leaves in October ; this bug is allied 

 to the HelopeUis which attack tea and cacao and does the 

 same kind of damage. Citrus trees were attacked by a shot-hole 

 borer, XyIebon(s sp., in June, by an Aphid in November and 

 by mites on the bark in December. Weevil larvae, probably those of 

 Odoiporus lonyicollis, attacked plantains in November. The cigarette 

 beetle, Lasiodernm serricorne, was an important pest of dry tobacco. 

 A small Trogositid beetle, which was also supposed to be attacking the 

 tobacco, was shown experimentally to be predaceous on this beetle and 

 on A raeceriis fasciculatus. 



Among green-manure plants, Albizzia was attacked by a scarlet mite 

 in February, by Xyleborus in June and by Terias silhelana and Arbela, 

 quadrhioiata m September. A mealy-bug attacked Tcphrosia Candida
