The following Elateridae are injurious to inaize and devour the 

 seed, roots and stem of the plants ; Agriotes lineatus, L., A. obscurus, 

 L., Melanotus puncfolineatus, Pelerin, in Hungary; Athous hirtits, 

 Hbst., in Podofia and Bukovina ; Athous niger, L., and A. niger, 

 var. scrutator, Hbst., in Kiev. According to Del Guercio, the larvae 

 of these beetles feed from October to May on decomposing organic 

 substances, so that the destruction of weeds in the fields is unimportant. 

 The cultivation of the soil during droughts, when the larvae prepare 

 to pupate between the end of March and the end of April, may have 

 some practical importance in Italy. In Russia, it might be necessary 

 to postpone this cultivation for IJ or 2 months, as the larvae do not 

 pupate before the end of July. A new enemy of adult Elaterids, viz., the 

 Carabid beetle, ^/osci/s cephalotes, L., is recorded. Among the Tene- 

 BRiONiDAE, the imago of Crypticus quisquilius, L., is injurious in Italy 

 and France, but no damage by it in Russia has been observed. 

 Tetraneura ulmi, Deg., attacks many plants, including maize, in its 

 root-form, while the leaf-form lives on elm trees. Against the root 

 form, the root of the stubbles should be burnt in situ. Maize should 

 not be sown near elms, nor elms planted near maize. The Ufe-history 

 of Tetraneura rubra, Licht., resembles that of T. ulmi. Other aphid 

 pests of maize are : — Pentaphis setariae, Pass., in Italy ; Aphis zeae, 

 Rosl., A. maidis. Pass., and ^4. maidis-radicis, Forbes, in North America ; 

 A. sorghi, Theo., and A. runiicis [papaveris, F.) in Russia; and A. 

 sorhi, Kalt, and A. podi in the Crimea. The roots of maize are 

 attacked by Heterodera radicicola, Greef, and H. schachfii, Schmidt.

A general review is given of the work done by the Station and by 

 individual members of the staff, some of which has not been com- 

 pleted, owing to the war. The effects of machorka* (tobacco) dust on 

 the surface and subterranean pests of beet was investigated by the 

 author. The dust proved effective against nematodes and flea-beetles 

 and was also more or less effective as a manure. Some experiments

 centage of nicotine. — Ed.]
