perfectly sound, and has continued so to the present time. I applied the 

 tar only to the unsound places. I cannot speak from actual experience further 

 than I have stated, and I cannot be sure that the improvement in the apple 

 trees before recorded resulted from this application ; but such was the im- 

 pression of the owner. 1 would recommend W. to use the tree guard, of 

 which a description was given in a former volume of this Magazine (vol. xiii. 

 p. 166.), as the only effectual protection against animals having the very vexa- 

 tious propensity of which he complains, and which, at the same time, never 

 injures the trees. The cows referred to in that article, having been com- 

 pletely foiled by the guard recommended, began to attack the bark of some 

 elms of large growth. As soon as this was observed, the gas tar was applied to 

 the wounded parts, and they did not proceed any farther that season ; but the 

 following spnng, as soon as they were turned out, they began their attacks 

 again on the new bark formed over the former wounds ; exposure to weather 

 having, it is presumed, destroyed the offensive qualities of the application. 

 I would not, therefore, recommend any one to depend on the tar alone, as it 

 would require frequent renewing, and irreparable mischief might result from 

 inattention to this in time. — Charles Lawrence. Cirencester, Sept. 23. 1838. 



Tlie Genus Corrce^a.. — How many species of Corrae^a are there ; and are all 

 of them natives of New South Wales? Are Corrst'a rufa and C. Milnen'i 

 distinct species, or merely seminal varieties ; and where are the two latter to 

 be purchased, and at what |)rice ? Have any seedlings been raised in this 

 country; and, if so, have any varieties been produced by that means ? I should 

 be greatly obliged to any of the readers of the Gardener''s Magazine, if they 

 would answer these queries, or such of them as they can. — S. Kensington, 

 Sept. 28. 1838. 



Afr. Westwood's Answer to various Questions respectifig Insects. — The 

 insects in the pear leaves just received, are dead larvae of a small lepidop- 

 terous insect, which I presume are the young of Argyromyges Clercke//a 

 (Tinea CI. Linn.), described in the Gardener'' s Magazine, vol. xiii. p. 524. 



The little blue beetles, found feeding on the willow leaves, are Chrysomela 

 (Pha3\ioH) vitellinas, a very common species, of which the larvse feed in 

 company, forming little regiments, and keeping in a line. 



It is impossible to make anything out, decisively, respecting the grubs sent 

 from the cauliflowers at Oxford. They are evidently dipterous, and, most 

 likely, belonging to one of the ilfuscidze ; perhaps a species of Anthomjia, 

 allied to A. ceparum, the onion fly, described in my series. 



The insect which perforates the deal laths from Petersburg, sent by 

 W. H. Baxter, is »S'irex Juvencus, female, in the larva state. See Arb. Brit., 

 art. Pinus, p. 2140. 



The insects sent by Larix from Neath, South Wales, which attack the trans- 

 planted larches, are Hylobius abietis. See Arb. Brit., p. 2140. I shall probably 

 make this species one of my series. — J. O. Westwood. Oct. 4. 1838.

A PAPER was read " On the Cultivation of the Strawberry," by John Dis- 

 ney, Esq., F.H.S. The author stated that, having found the ordinary modes 

 of preserving clean the fruit of the strawberry, while growing, ineffectual, he 

 had devised" the following method. He first raises the bed into ridges, 

 from 4 in. to 6 in. high, and 24 in. apart at the upper edge ; planting the runners 

 in the valleys, at the distance of 12 or 15 inches. Then, when the flowers ap- 

 pear, he paves the whole of the ground with the large flat pebbles easily pro- 

 cured in gravel-pits, selecting such as are 3 or 4 inches in diameter, and about 

 1 in. thick. From this plan the author finds that he derives the following 

 advantages : — 



1. The rain water runs in between the pebbles, and readily finds its way to
