NOTES ON A PSYCHID NEW TO NORTH AMERICA 
(FUME A CASTA PALLAS, Lepidoptera: Psychidse) 
By Donald W. Farquhar 1

In 1931, workers from the Gipsy Moth Laboratory in 
Melrose Highlands, Massachusetts, found examples of an 
unknown case-bearer associated with the introduced beech 
scale, Cryptococcus fagi Bar., near Jamaica Pond, Boston, 
Massachusetts. Specimens of the case-bearer brought into 
the laboratory were observed to feed on the eggs and 
agamic females of the scale, but since this choice of food 
was decided to be purely incidental and the chief interest 
of the laboratory was in the scale rather than in the case- 
bearer, no further work on the latter was done. The writer, 
however, was interested in the identity of the insect and sent 
examples of the cases to Dr. Frank Morton Jones of Wil- 
mington, Delaware, who was unable to place them among 
any of the known North American forms and suggested 
that an attempt be made to secure adults. In 1932 two 
male adults were obtained, and in 1933 over 2,000 adults of 
both sexes were reared from larvae collected just prior to 
pupation ; this ample material enabled careful study, result- 
ing in the determination of the insect as the European 
Fumea casta Pallas. A discussion of the characters estab- 
lishing its identity is given in the paper which follows, 
while the present paper deals with the distribution and 
biology. 
ir rhe writer wishes to express his deep appreciation to Frank Mor- 
ton Jones, specialist in the Psyehidse, who has been most generous in 
giving of his time and knowledge. A paper which follows, and which 
bears the name of the writer of the present paper as coauthor, is al- 
most entirely Dr. Jones’ own work. 
Thanks are also given to Harold Morrison, C. F. W. Muesebeck, 
A. B. Gahan, and R. A. Cushman, all of the taxonomic unit of the 
Bureau of Entomology, who examined parasitic material and made 
determinations where possible.
