40 THE FLORIDA BUGGIST 
atumbler. On March 7th there was only one living mite and the 
eggs were still red in color, but they were not normal nor had 
they hatched. They were soft, and when broken contained a 
liquid instead of a young spider. Another collection of leaves 
made just after the freeze and examined on February 15th, gave 
the same results; the eggs did not hatch. On another tree there 
were many unhatched eggs. On February 17th these appeared 
to be very soft. On these same leaves there were 13 young mites 
that had evidently hatched since the freeze. No doubt the 
adults, young mites and eggs were largely killed when in exposed 
places. 
In fairly well protected spots the adults and young were not 
killed. On February 29th there were 23 adult females, 8 males 
and 10 young mites living on a few camphor leaves. The eggs, 
however, did not appear to be normal. They had that same dull 
look as the others that never hatched. 
The observations on this mite show that all.stages are easily 
affected by the cold, and especially are the eggs damaged, which is 
contrary to expectations. The adults survive only in protected 
places. On June 1 there were practically none of this species pres- 
ent, while there are specimens of Tetranychus sexmaculatus and 
Tetranychus citri. 
NOTES ON SOME INSECTS OF SOUTH FLORIDA IN 1917 
By R. N. WILSON 
(Paper given before the Florida Entomological Society.) 
The above title is somewhat too inclusive, as the observations 
were made almost entirely in Palm Beach County, tho some were 
made in other counties. 
Dictyophorus reticulatus—The Lubber Grasshopper. These 
large grasshoppers were very numerous on some of the drained 
saw-grass lands along the Palm Beach Canal in the Everglades, 
but because this land has not yet come under cultivation little 
damage resulted. Along the shores of Lake Okeechobee where 
severe injury has resulted from their attack during certain years, 
these grasshoppers were present in small numbers, but were not 
troublesome. The writer’s previous experience with this species 
at Fellsmere and other points had proved that it could be controll- 
ed with the so-called “Kansas Mixture” (bran, paris green, syrup 
and citrus fruit) even when there was a large influx from sur- 
rounding lands. None of the melanic forms were found, as would 
be expected from the known distribution of the various forms.
