thoini, and this revision, the first for the tribe, should provide
a basis for future biological studies. A revision of the larvae
and adults of the genus Protodejeania and of several other
tachinid genera is also in progress, as is a study of the biting
midges of Polynesia.
Dr. Nicholas S. Obraztsov continued his study of the New
World moths belonging to the family Tortricidae, with the objective
of establishing a family classification that is coordinated
with that for the European tortricids.
During the year the collection of insects and spiders was increased
by 88,000 specimens, which brings the total collection to
well over 12,000,000 specimens. The complete re-curating of the
Hymenoptera collection progressed satisfactorily.
Through the curatorial efforts of Mr. Wilton Ivie, the usefulness
of the agelenid spider collection was improved, and
Dr. Arnaud curated the tachinid fly collection, identifying and
segregating 370 holotypes. Most of the material collected by
Drs. Rozen and Rindge during their field trips was mounted
and labeled. Professor T. C. Maa of the Bernice P. Bishop Musum,
Hawaii, who visited the Museum, collected ectoparasites
from preserved bats in the Department of Mammalogy and the
Archbold Collections. As a result, the Department of Entomology
at the present time has the finest collection in the world
of the bat-fly of the genus Ascodipteron.
Exhibition activities in the department centered around plans
for the new Hall of the Biology of Invertebrates. Dr. Rozen and
Miss Alice Gray worked with other members of an interdepartmental
committee on plans for the following sections: the origin
of life, viruses, evolution and speciation, classification, communication,
and biological rhythms. In addition, Miss Gray
spent considerable time collecting insects and other invertebrates
in the New York area for use in the new hall.
