above is both cheaper and better. Eeferences will be found to it in the 

 Index, under the name of " Chiswick Compound." 



Where the Mites are observable, as in the case of this attack, and 

 also in that of Hay Mite, collected in great masses on the ground, all 

 common sense measures (which will suggest themselves) will be 

 desirable for shovelling them up, or otherwise collecting them, and 

 destroying them. 



STRAWBERRY. 



strawberry-leaf Beetle. Galenica tenella, Linn. 



The Galenica (or as it has recently been called, the GaleruceUa) 

 tenella, is a very little beetle, only an eighth of an inch, or slightly 

 more, in length, which was observed last year doing much harm in one 

 district to Strawberry leaves. The beetle may be easily identified 

 from description with the help of a fairly strong magnifier. It is 

 oblong-ovate, and convex in shape, and the general colour is of some 

 shade of dull yellow, or brownish. Looked at more minutely, the 

 head is yellow, with a broad black stripe or baud across the top. Tbe 

 thorax or fore body also of some yellowish tint, with, in some instances, 

 a dark line along the central furrow, and on each side of the furrow is 

 a small round depression. The wing-cases pitted, so as to be slightly 

 granulated, on the surface, and rather shiny, and in the specimens 

 sent somewhat variable in colour, sometimes yellowish, sometimes of 

 a brown tint, with the margin and the suture yellow, and occasionally 

 a spot on the shoulders of a dark brown. The body black beneath, 

 with the tip of the abdomen pale ; legs pale ; and the horns long, palest 

 at the base, black towards the end. 



This kind is recorded as being found " in this country in July, 

 frequenting Willows, Alders, &c." ; and in Germany it is mentioned 

 by Kaltenbach, as being repeatedly noticed by himself on young plants 

 of Spirma nlmaria (Meadow Sweet), and "once in greater numbers " on 

 the Potentilla anserina (" Silver Weed" with us), of which it greatly 

 damaged the leaves by its gnawings. 



The Spircea, and still more the Potentilla, are nearly allied to the 

 Strawberry, so that it is not surprising that it should be found on this 

 plant ; but still, until the observation of it was sent from Hants, I 

 was not aware of it having been noted as a Strawberry pest. Plentiful 

 samples, both of the beetles and of the injured leaves, were sent ; and
