species. The features most characteristic of the species and enabling 
its ready recognition are the peculiar character of the second pair of 
lobes, the more massed or irregularly circular arrangement of the 
paragenital glands, and the number and arrangement of the dorsal pores.

FATAL TEMPERATURE FOR SOME COCCIDS IN GEORGIA. 
By W. M. Scott, dAilanta, Ga. 
On the 12th and 13th of February, 1899, Georgia experienced the 
coldest spell of weather that has visited that State for many years. 
In Atlanta the temperature fell to 5° F. on the 12th and — 8° on the 
13th. In south Georgia, reaching to the Florida line, the minimum 
temperature for the 15th ranged from 0° to —6° F. 
This severe freeze had a destructive effect on certain scale insects, 
while others seem not to have been affected at all. On February 28, 
fifteen days after the freeze, | commenced to investigate the condition 
of the San Jose scale (Aspidiotus perniciosus) in southwest Georgia, 
aud continued the work until infested orchards in nearly every portion 
of the State where scales exist were examined. Wherever cases of 
San Jose scale have been found in north Georgia, such severe measures 
have been adopted to eradicate them that opportunity was not afforded 
to note the effects of the freeze on the scale in this north Georgia 
section; therefore these notes refer only to south Georgia. 
In November, 1898, the San Jose scale was discovered at Albany, 
Ga., thoroughly infesting about one dozen peach and plum trees ina 
back dooryard. These trees were condemned and ordered either to be 
treated or dug up. The owner of the premises died soon thereafter, 
and the scales were left unmolested until February 28, when I inspected 
the premises again and found the scales apparently all dead. Upona 
thorough inspection of the infested trees, not a living scale could be 
found. The minimum temperature for Albany February 13 was — 4° F. 
The San Jose scale has been at Cuthbert, Ga., for several years, and 
large commercial orchards are infested. Some of these orchards had 
been treated before the February freeze and others had not. On 
March 2 I made an inspection of these orchards and only found a very 
few live seales. Orchards that had been sprayed with 25 per cent
