38 PARASITES OF GIPSY AND BROWN-TAIL MOTHS. 
first summer there remained of the stock at Washington about 1,000 
beetles. Among the colonies sent out the best success was obtained 
in Georgia. An orchard at Marshallville in that State, containing 
some 17,000 peach trees and covering about 85 acres, adjoined a 
larger orchard containing about 150,000 trees, all scatteringly in- 
fested with the scale. The ladybirds were liberated in August, 1902, 
in the smaller orchard, and an examination made 11 months 
later indicated that they were rapidly spreading and would soon 
cover the orchard. The number of beetles in all stages present was 
estimated at nearly 40,000. Colonies established in the Northern 
States perished. In the South the almost universal adoption of the 
cheap and satisfactory lime-sulphur washes destroyed the possi- 
bility of rapid multiplication and destroyed the majority of the bene- 
ficial insects. This species has not been found recently, but prob- 
ably exists in Georgia. The introduction and establishment of the 
species was successful, but it was practically killed out by the cheap 
and satisfactory washes in general use. Without the washes the 
probabilities are that the ladybird would be found at the present 
time occurring in great numbers in southern orchards. 
THE PARASITES OF DIASPIS PENTAGONA TARG. ° 
For a number of years the mulberry plantations of Italy had 
suffered severely from the attack of the msect known as the West 
Indian peach scale (Diaspis pentagona Targ.). This insect occurs 
in the United States and is widely distributed in other parts of the 
world. In the United States, however, it is not especially injurious. 
In 1905, at the request of Berlese, the writer sent parasitized Diaspis 
from Washington to Florence, Italy. One of the parasites which 
issued, Prospaltella berlesei How., was artificially reared in Florence 
by Berlese and his assistants, and at the time of present writing has 
been so thoroughly established in several localities that the ultimate 
reduction of the Diaspis to harmless numbers is confidently antic- 
ipated by Berlese. Similarly, Silvestri at Portici has introduced 
the same species from America, and also certain ladybirds, and is 
making the effort to import the parasites of this species from its 
entire range. 
THe Work oF Mr. GEORGE COMPERE. 
Mr. George Compere, employed jointly by Western Australia and 
California as a searcher for beneficial insects, for several years has been 
traveling in different parts of the world in search of beneficial insects 
which he has either sent or brought to California and Western Aus- 
tralia. One of the most interesting of his achievements was sending 
living specimens of Calliephialtes messor Grav., an ichneumon fly, from 
Spain to California. This species is a parasite of the codling moth.
