 segetis, a few specimens of Athous niger L. were recorded ; Elateridae were 

 reported at Tula and Riazan ; at Kharkov, Agriotes sp. ( ? ) caused injury 

 to wheat (i()0 acres were resown) and to cabbages ; at Kiev, beets were at- 

 tacked b}^ the adult .4. lineatus ; in Podolia, by Athous, Limonius, Mela-

 roides Fabr.), in Bessarabia, devoured young heads of rye; (7) Podosta ni- 

 grita F. was observed in fairly large numbers on the ears of wheat at Ekate- 

 rinoslav, its injurious action in relation to grain crops however is not yet 

 quite clear ; in the government of Kuban, it caused injury to beet ; at »Stav- 

 ropol it was found in quantities in grain fields, on Bassica Rapa oleifera 

 and other plants ; (8) Opatrum sabulosum I,., at Kiev, Astrakhan and Khar- 

 kov, caused injury to peas, melons, water-melons, cucumbers and young wheat 

 plants ; (9) Gonocephaliim pusillmn Fabr.. at Astrakhan, attacked plots sown

 jured roots of clover; at Kharkov it attacked clover and lucerne ; at Kher- 

 son, the roots of lucerne ; at Kiev, the adults preferred the leaves of the 

 peas to those of the beet ; at Stavropol this species was found on the leaves 

 and roots of lucerne ; (20) Sitones lineata ly., at Orel, Riazan and Kharkov, 

 on several pulses ; also found at Stavropol ; (21) Baris chloris Fabr. great- 

 ly injured (up to 80 "„) kohlrabi, the larvae devouring the whole of the stems; 

 rarely met with on the roots ; at Kharkov the insect caused serious injur\ 

 to cabbages; (22) Apion sp. attacked clover, at Orel; and was found through- 

 out Riazan; at Tula the number of larvae which usually feed on clover 

 had considerably diminished, in 1914 according to Sapozko, the ex- 

 cessive drought retarding, development and flowering cf the clover, and con- 

 sequently a part of the generation of the clover weevil was displaced in 

 its life cycle ; according to Stcherbakov's data obtained at the agricultural 

 experiment Station of Chatilov (government of Tula), Apion is harmless 

 agriculturally, and cannot be deemed to have any adverse influence on 

 the production of clo\rer seed ; at Tchernigov the weevil was found on a
