In reply to a subscriber it is pointed out that the leaves of pears 

 sent by him are infested with the mite, Eriophyes pyri, Pgst., which 

 causes the disease frequently mistaken for that due to the fungus, 

 Fusicladium pyrinum. These mites cause the formation of thick, 

 yellow or red scales on the lower surface of the leaves and are only 

 dangerous when they are so numerous as to bring about the withering 

 and dropping of the foliage. The removal and destruction of the 

 damaged leaves and spraying with kerosene emulsion before the un- 

 folding of the buds, in which the pests winter, are recommended. 

 These mites also attack service trees, Cotoneaster, dogwood and quince.

In reply to a subscriber, it is stated that the leaves of Laurus 

 nobilis, L., sent by him, are infested with the Psyllid, Trioza alacris, 

 Flor, attacks of which cause curling of the leaves. The removal and 

 destruction of the infested leaves is the only known, remedy ; seedlings 

 should be disinfected, if necessary, with carbon bisulphide or 

 hvdrocvanic acid.

This note records the discovery in Chili of a new Microlepidopteron 

 injuring potatoes quite as badly as, if not worse than, Gelechia 

 galbanella, Zell.,* which was present in company with it ; it has been 

 named by Mr. Klunder van Gyen, Dichortieris {Trichotaphe) tangolias.

 January 1916, pp. 950-958, 2 plates. 



Damage to fruit trees by Capsid bugs is well known in the United 

 States and Canada. Attack on apples in Britain was first recorded 

 in 1910, since which date several other records have been made. 

 A census of the bugs found in affected orchards seems to show that the 

 green Capsids, Plesiocoris rvgicollis and OrtJwtylus marginalis, cause 

 most of the damage, and that of these P. rugicollis is the more 

 inj urious. The brown Capsids, Psallus ambiguus and Atractotomus mail, 



[♦As this species is a European one, only known to feed on moss, this is 

 probably a mistake for the well known Phthorima^a operculella. — Ed.]
