governments, in the first half of October, and in South Russia, at the 

 end of that month and the beginning of November. The eggs remain 

 over the winter and hatch in the sprhig of the next year (in Bessarabia, 

 in the first half of April). The larval stage lasts six weeks, and pupa- 

 tion takes place in the earth, at a depth of 2-3| inches, and lasts three 

 months and frequently longer. Remedies include trap-belts to prevent 

 the females, which cannot fly, from getting on the trees to oviposit 

 and digging the soil of the orchard, followed by rolling, against the 

 pupae. Where Jione of these remedies have been applied in autumn, 

 the trees should be sprayed with some insecticide against the cater- 

 pillars. The author has obtained good results with the following 

 recipe : 6 oz. of Paris green, 12 oz. of quick lime, 2| lb. of green soap 

 in 27 gallons of water, the soap being added to make the liquid adhesive. 

 It is better to prepare it on a large scale, and 54 gallons may be pre- 

 pared as follows : — About 48 gallons of water are poured into a wooden 

 barrel, cut in half. The Paris green (mark 707) is moistened with 

 some water into a paste and then washed into the barrel ; the lime 

 is slaked and, when thoroughly mixed with water, poured into the 

 barrel ; the soap is dissolved in some hot water, to which cold water 

 is afterwards added to cool it, and the whole poured into the barreL 

 The remaining quantity of water is added and the bulk well stirred 

 and mixed. It is advisable to spray twice ; when the buds start ta 

 unfold and again after the blossoming.

The author refers to an article published in the above journal on 

 the Tenebriouid beetle, Podonta nigrita, in which it is stated that this 

 insect is recorded for the first time in Russia, and that neither its life- 

 history nor its various stages are known. He points out that he 

 published in 1897, in No. 46 of the Bulletins of the Ministry of Agricul- 

 ture and CrowTi Estates, a note on his observations on this insect, the 

 larvae of which were discovered by him during his investigations on 

 the parasites of the com weevil. He then stated that the imagines 

 of these pests injure grain and rape crops, while the larvae, which are 

 similar to those of Tenehrio molitor, probably feed on the roots of plants. 

 A parasite of the insect was also discovered, Anthrax pggarga, Lw., 

 probably a variety of A. ixion, F., which, in one case, destroyed 50 

 per cent, of the larvae of P. nigrita.

 insect is given from the report of the station at Sniiela. j
