Ministry of Communications to the necessity for more rational buildings- 

 for elevators and grain stores and for a thorough cleansing and disinfec- 

 tion of the same between the removal of one cargo and introduction 

 of another, and also confirms the resolutions of a special conference of 

 railway officials and entomologists in 1912 in Moscow, with regard to 

 Calandra granaria, prohibiting the acceptance for transport of grain 

 infested with, that pest, and dealing with the method of isolation of 

 grain cargoes discovered during transport to be infested with this 

 weevil. The Congress referred this resolution for consideration at the 

 next Congress, where this question ought to be re-opened and thoroughly 

 discussed, and adopted a resolution proposed by V. Plotnikov urging^ 

 the necessity of special disinfecting stores at the Custom houses for 

 cotton seed imported into Russia from abroad. 



III. On the question of the direction of, and co-operation between, 

 the work of entomological organisations, the Congress adopted a 

 resolution, which recommends (1) the establishment of a " Russian 

 Society of Economic Entomologists," the articles of association of 

 which are to be discussed at the next Congress ; (2) the establishment 

 of some central authority to which the separate Entomological 

 Organisations should present yearly reports on the local insect pests 

 and the damage caused by them ; and (3) the foundation of a journal 

 of Applied Entomology.

This paper consists of a review of damage caused during 1913 by 

 insects and fungi in Denmark. Cereals were attacked by the larvae 

 of Tipida paludosa, which caused severe injury at Thisted, where as 

 early as the end of May, about five acres of oats were destroyed. 

 The larvae of Phyllopertha horticola, at the beginning of October, 

 destroyed the rye at Kibaek. Heterodera schachtii var. avenae 

 was, as usual, very common in the oat fields all over the country. 

 The attacks of these nematodes were first observed at the end 

 of May, and in many locahties over 50 per cent, of the fields 

 investigated were found to be infested. In most cases, the cultivation 

 of oats several times in rotation was held to be responsible. The 

 first puparia of Hylemyia coardata were found on the 9th May. 

 The infested area, which previously had been chiefly in Lolland- 

 Falster and the South of Fyn, has during the last ten years moved 

 northwards. The severity of the attack in 1913 is attributed 

 to the mild winter, which favoured the early development of the 

 fly. Oscinella [Oscinis) frit has been abundant in many localities 

 and caused serious injury, but less so than in 1912. Late-sown oats 

 were chiefly attacked. As in 1912, Chlorops taeniopiis was very 

 scarce. Attacks on rye by the caterpillars of Trachea {Hadena) secalis 

 have as usual been recorded in May and June, and in one 

 locality, as early at the end of April. At Aarhus, the severity 

 of infestation has diminished successively during the last few years
