“when immense numbers appeared simultaneously and completely 
cleared the orchards of the county of the seale.” 
An interesting ladybird of the genus Scymnus was found in 1892 by 
Dr. Blaisdell preying upon the San José Seale at the Coronado parks, 
near San Diego. This species was described by Dr. Blaisdell as Seym- 
nus lophanthe n. sp., but has not proved very effective in destroying 
the Aspidiotus. 
In the September, 1892, number of the Agricultural Gazette of New 
South Wales Mr. A. Sidney Olliff reported the receipt of a typical 
series of Aspidiotus perniciosus on the fruit, leaves, and twigs of Pear 
from West Maitland, New South Wales. Mr. Olliff further stated that 
although this species had not previously been recorded as oceurring in 
Australia, it had been known to some fruit-growers for a number of 
years. 
In an important paper read by Mr. Alexander Craw before the State 
Horticultural Society of California, December, 1892, the San José Scale 
is stated to be unquestionably of foreign origin, and it is further sur- 
mised, on the authority of Mr. John Britton, of San José, that it was 
introduced into California upon trees received from Chile by the late 
James Lick. 
In Bulletin 7 of the New Mexico College of Agriculture, published in 
June, 1892, Mr. C. H. Tyler Townsend, entomologist of the station, 
records the occurrence of the species at Las Cruces upon apple, pear, 
plum, peach, quince, and rose, and states that it was brought into New 
Mexico on young trees from California. The winter eggs are mentioned 
in Mr. Townsend’s account as turning orange-yellow in spring and 
hatching the first or second week in May. 
SUDDEN APPEARANCE OF THE SPECIES IN THE EAST. 
The first week in August, 1893, Dr. C. H. Hedges, of Charlottesville, 
Va., sent specimens of pears and peaches affected by this insect to the 
Division of Vegetable Pathology of this Department, on the supposi- 
tion that the scales were the manifestation of a fungous disease. They 
were referred to this Division and Dr. Hedges was informed of the 
destructive character of the insect, and advised to spray with kerosene 
emulsion, as examination of the specimens showed that the insects 
were hatching at the time. He was unable to trace the origin of the 
trouble. He sent specimens from pear, currant, plum, Japanese plum, 
and dwarf apple. 
In view of the great importance of the subject, Mr. E. A. Schwarz 
was sent to Charlottesville about the middle of August to make a 
thorough investigation, and in December Mr. D. W. Coquillett was sent 
to continue them, and to definitely delineate the area of infection. From 
the detailed reports submitted it appears that the scale occurs most 
abundantly ina little pear orchard forming a square of about one-third 
of an acre about one-third of a mile from the center of the city, adjoin- 
ing one of the main roads leading into the open country. The orchard
