Nebraska M. H. Swenk (March 20): The lilac form of the oyster-shell 
scale is very abundant in some parts of northeastern Nebraska. 
Colorado C. F. Gillette (March 6): I am not sure that I noted in any 
of ray reports last year that the oyster-shell scale, which was 
becoming so abundant on our ash, willow, and cottonwood trees, 
in northern Colorado, and on the purple lilac, was almost ex- 
terminated during the winter of 1929-30 by the severe cold 
weather -- the temperature here at Fort Collins going as low 
as 38.5 degrees below zero. We were only able to find occa- 
sional live specimens of the scale in this vicinity Last sum- 
mer.

again appearing in small, scattered infestations i^The/'Vai 6 - 1 ' 
ley. In most cases the infestations ore slight, especially 
in the citrus, although one rather serious infestation was 
found on grapefruit in Tempe. This infestation was attri- 
buted to a nearby infestation on Fittosporum tobira which 
had been reported too late to control by means of establish-

case where the beetles were established last year a nearly 
corjplote control was secured.
