Louisiana, Mississippi, District of Columbia and New York. In its more 

 northern localities it is scarce. In the south, where attention has only 

 recently been drawn to its injuries, it multii)lies rapidly, and becomes a 

 serious enemy to the peach and pear. 



The New Peach Scale {Diaspis lanatus, Morgan & Cockerel)). — 

 This species seems to be indigenous to the West Indies, where it has 

 been found in Jamaica, Trinidad, Martinique, Barbadoes, Santo Domingo 

 and Grand Cayman. In the West Indies it occurs upon a great variety of 

 food-plants.* In Ceylon it has been found to affect cultivated geranium 

 plants. In the United States, it is now known in one locality in Florida, 

 another in Georgia, and in the District of Columbia, doing very consider- 

 able damage in each of these localities to peach trees. Its introduction 

 from the West Indies into the United States is apparently rather recent. 



The San Jose or Pernicious Scale {Aspidiotus perniciosus, Comstock). 

 — This insect is known positively to occur in Australia, Chili and Hawaii, 

 outside of the United States. In the United States it made its first 

 appearance rather more than twenty years ago in the vicinity of San Jose', 

 Cal. It was probably introduced at that point throngh importations of fruit 

 trees and shrubs made by Mr. James Lick. Ito original home is not 

 yet known. The supposition that it is a Chilian insect, originally made 

 by Mr. Alexander Crow, seems negatived by recent evidence, and it is 

 probable that it reached Chili from the United States. It spread through 

 California, reaching British Columbia within the last two years, and 

 spreading eastward, it reached Idaho on the north, and TJevada, Arizona 

 and New Mexico on the south, also within the last few years. A chance 

 importation of California nursery stock has also established it at one 

 point in Missouri, one in Florida, one in Virginia, one in Indiana, three 

 in Maryland, two in Pennsylvania, one in New York State proper, and 

 several in Long Island, and many in New Jersey. 



7he Red Scale of Florida {Aspidiotus ficus, Ashmead). — This scale is 

 probably of West Indian or South American origin. For many years in 

 the United States it was known only in the State of Florida, where it was 

 introduced first into an orange grove near Orlando upon a sour orange 

 tree brought from Havana, Cuba. Investigations made by Comstock in 

 1880 showed that it was an abundant species in the public gardens of the 

 City of Havana. From the introduction at Orlando, the species spread 

 rapidly through the orange-growing regions of Florida. Until recently it 

 was supposed to have been introduced into Louisiana during the New
