The tables given below show the values of the dally abundancy: the days of survey are to be found on the horizontal coordinate whilst the values of abundancy are on the vertical one. Generally, we may state that the curves give the most conforming picture of the reality in time. Their conformation afford* us with the anserws to our two problems indicated before: to specimen dencity and its numerical establishment. Of the values of the daily abundancy of the curves or tables we may, by the use of mathematical averages compute on one hand the abundancy within the squares and on the other the abundancy of scavengers for Potentillo-Quercetum during the spring. The numerical values are given at the end of the characterization of every beetle species: Thanathophilus thoracicus L. /Table 1./ In the square I. the abundancy is evenly low till the middle of May /2-3/, and after a sudden increase /19/ the curve became approximately straight in the second half of May. This does not change till the middle of June. Square II. differs insofar from square I. that the abundancy values reach constancy but gradually up to the second half of May /7-10/. The abundancy of square I.: 7,3 - 7 The abundancy of square II.: 8 Spring abundancy: 7- 8/1200 m

2 Necrophorus vespilioide3 Kerbst /Table 2./ Whilst square II. - though of incomplete data - the constancy of abundancy evenly /2-3/, - after an apex showing in the second half of May /4/, - there is a considerable oscillation in square I. even in June. With regard to the deficient data and their oscillation, the abundancy of this species is supposedly constant only in the second half OÎ June, in early summer.
