number of specimens of the same parasite from Aspidiotus perniciosus, 
and Mr. E. M. Ehrhorn states that it is the most abundant parasite of 
this species around San Francisco. Mr. Ehrhorn also reared from the 
same scale insect Aphelinus mytilaspidis LeBaron, and Asp idiot ipha (jus 
citrinus (Craw). Mr. Alex. Craw, in the report of the State Board of 
Horticulture of California for 1891, made the statement that the 
Aphelinus fuscipennis just mentioned had been found doing such 
effec'ive work in subduing the San Jose scale in an orchard in the 
neighborhood of Los Angeles that the complete restoration of the 
orchard was confidently looked for. Mr. Coquillett informs me, how- 
ever, that while this orchard did recover to a very large extent, it 
afterwards became reinfested, and he is not at all sure that the partial 
restoration was due to the work of this parasite. Several times in his 
experience he has seen trees recover and the scales die off, without 
apparent cause. No exit holes of parasites were found in the scales? 
and the insects seemed to have died from some disease. A figure of 
Aphelinus diaspidis is introduced, which will assist in the identification 
of A. fuscipennis, the only eastern parasite yet found.*

NEW FACTS AS TO THE ORIGINAL HOME OF THE SPECIES. 
At the time of the printing of Circular No. 3, in April 1894, I was 
obliged to follow the latest California utterances on the subject of the 
probable original home of the San Jose scale, and stated that it was, 
according to the most trustworthy authority, first brought to California 
on trees imported from Chile by the late James Lick, about 1870. 
This statement was derived from a paper read by Mr. Alex. Craw 
before one of the California Horticultural Conventions, and Mr. Craw 
gave as his authority Mr. John Britton. I have since corresponded 
* Since this was written a single specimen of Anaphes gracilis How. was reared 
from specimens of the scale collected at Riverside, Md. The type of this species was 
reared in 1880 from Alytilasjiis pomorum, the common oyster shell hark-louseof the 
apple.
