a 
Hatching of evgs of Centeter cinerea.--M. H. Brunson, Moorestown, 
resorts that egzs of C.. cinerea laid during the past season in the 
field and in the orepagation cage have recently been examined, to 
determine the percentage of eg:s that hatched. ne results of the 
examination are shown in the following table:

The parasitized beetles from the field and from the propagation 
cage were handlea idéntically. The only apparent reason for this 
marked difference in the percentage of beetles forming puparia was 
that many of the parasite larvae died because the beetles obtained 
from the propagation cage died immediately after they were placed in 
the cages for puparia formation. Examination of the remains of the 
beetles showed that tieir death was due te a disease. This condition 
apparently caused a low »puparia formation in 1932 but in 1931 puparia 
formation was aoout the same in beetles collected in the field and 
those Clore y in the propagation cage, which indicated that the dis— 
o,? 
ease was not present in wie ae used in propagation that year.

Beet leafhovper predictions for 1934.--J. wh Chamberlin, of the 
Twin Falls, Idaho, daboratory , reports that the prospects are for low 
populations of the beet leafhopper (Hutettix t PE Ey Nene Bak.) in the 
counties of Twin Falls, Jerowe, Minidoka, and Cassia, Utah, during 
the coming season. As a result, "curly top," the disease resal iia 
from beet leafhopper infestations, is not expected to be a serious 
factor in reducing yields of sugar beets or other Repo crops 
in these counties. This prediction is based principally upon studies 
of weather conditions, leufhopper populations, and host plant condi- 
tions throughout the summer and fall of 1933 and during the past 
Winter. Considering the unfavorable summcr and fall weather condi- 
tions, together with the small numbers of leafhoppers that entered 
hibernation, it is believed that the extremely mild winter of 1933- 
64 will be of little importance, so far as leafhopper injury the 
coming season is concerned. However; no information available at 
this time would encourage the planting of beets in close proximity
