Bothynoderca ])unrtivenlriii, (jlerm., has decrcsased during the last 

 three yeai's and in the year under report no measures were taken for 

 its control. 



BoGOYAVLENSKY (S. (J.). Tanymecus paUiatus, ¥., pp. G-23, 8 figs. 



The Editor remarks that this pest of the subfamily Tany- 

 MECINAE is widely spread in Western Europe and in iiussia, when; 

 it has been very conunon during the last three years and tlie author 

 was entrusted with the investigations on its biology. Of the beetles 

 found in tlie trap trenches, T. 'palliatus constituted 70 per cent., and 

 it is thought that the increase in their numbers is related to the 

 decrease in those of Bolhynoderes punclivenlris. The beetles appear 

 during the first half of Ay)ril on sugar-beets and also other plants, 

 including Uiilca, Chenopodium album, Bela vulyari.s, Sojd hispida, 

 ])eas, clover, vetches, chicoiy, sori'el, H>isynd)riti-iii, I)oppy, potatoes, 

 Lontiuvhpurjmreuni, \j. (dead-nettle), maize, onions and garlic, although 

 it is uncertain whether all of these actually serve as food. Considerable 

 damage is done to the foliage of the food-plant. Pairing begins soon 

 after the appearance of tlie beetles in spring and is repeated during the 

 oviposition period, which lasts for two to three months. In nature 

 the eggs are pi'obably chi(;fly deposited in the soil near the base of the 

 ])laiits. The egg-stage lasts from J 4 to 2i) days, according to the season. 

 The larvae, which are figured and described, moult at intervals of two 

 weeks. The investigations have not been completed , and it is uncertain 

 w'hether they live more than one year or Avhcther they injure the roots 

 of beet.

The Editor points out that this insect was first found in trap- 

 trenches in f 90G by i*rof. V. Pospielov and that its eggs and larvae were 

 unknown. The author has now been able to obtain and describe both. 

 The development of the egg in May lasts about 27 days.
