area is described and notes are given on signs l)y which the presence of the insect 

 may be known, and on the present conditions of infestation by this insect in the 

 Ohio grajae belt. Tlie species is described in its different stages and notes are given 

 on its life history. The number of eggs laid by female beetles varied between 106 

 and 184. The duration of the egg stage, as determined by the author, was from 9 to 

 12 days. Experiments were devised for the purpose of testing the l)urrowing power 

 of the larva?. A glass tube i in. in diametei'and 17 in. in length was bent so that 

 4 in. were vertical, and filled with loose earth. Grubs placed on the surface of the 

 soil in the vertical part of the tube made their way down into the soil and through 

 the whole length of the tube within a few days. One grub made its way through 7^ 

 in. of tightly packed soil within 6 days. It was found that the larvje were able to 

 exist for a considerable time without food. The insect feeds chiefly on grapes, but 

 is also known to attack the Virginia creeper and occasionally other plants. A 

 number of experiments were made in testing remedies for controlling this in.sect, and 

 as a result of these experiments it is recommended that the soil be thoroughly stirred 

 between the r(jws and near to the vines, so that the insects may be exposed in their 

 ]Hipal condition. The beetles may be collected by special catchers so constructed 

 that they may be ojierated rapidly, and these remedies may be suijplemented by 

 thorough spraying, preferably with arsenate of lead. It appears that no one method 

 can be entirely relied ujion to control the insect. A brief bibliography of the species 

 since 1866 is also given.

 Agr. Soc. and School Agr., 4 [190;/), Xu. 5, pp. 197-208, 2)ls. 4). — Brief notes on the 

 biology of insects, with a special account of the habits and life history of leopard moth, 

 plum-stem borer, ami a mmil)er of scale insects, together with a brief discussion of 

 peach-leaf curl. 



Sugar-cane borers — insecticides and fung-icides, P. Bona.mk {Sta. Agron. 

 Mauritlu-'i, Bui. No. 7, 1902, jjp- 28). — The common sugar-cane borer of Mauritius is 

 not Dlatrxa saccJiaralis, but Sesumia nonagrioides. Notes are given on the habits and 

 life history of this species, a translation of a note on the sugar-cane borer by H. 

 Maxwell-Lefroy is presented, and a brief discussion is given of the formuhe and 

 method of applying conunon insecticides and fungicides. 



Cabbag-e-root magg'ots, G. H. Carpenter {Jour. Depd. Agr. mid Tech. In.<itr. Ire- 

 land, 3 {1902), No. 1, pp. 109-113, pi. 1). — Biological and econ()mic notes on I'horbia 

 brassicx. The species is reported as having occurred in unusual numbers during the 

 year 1901. In combating this insect it is reconunende<l that close attention be given 

 to the i^lants in order to determine the egg-laying period, and that eggs should be 

 destroyed at once. A dressing of gas lime has been found useful in keeping off the 

 flies. The use of tarred cards around the stem of young plants may be relied upon 

 to some extent in preventing the deposition of the eggs. Brief notes are given on 

 the natural enemies of this insect.

 a number of species of Coccid* belonging to the genera Epilachna, Coccinella, Calli-

 bibliography of works relating to Australian Coccidaj is appended to the article.
