[Dec., 
Dr. Pilsbry has completed the publication of a monograph of the 
Hawaiian tree snails, Achatinellidce, together with a supplement 
describing new material collected in 1913. The preparation of a 
monograph of the family Tornatellinidce., also largely Hawaiian, is 
well advanced. 
Insects. 
Dr. Henry Skinner, head of the department of Entomology, reports 
that he and Mr. E. T. Cresson, Jr., have rearranged the families 
Gyrinidse, Hydrophilidae and part of the Scarabaeidse among the 
Coleoptera and the exotic and American Syntomidae, Uranidae and 
the genus Catagramma among the Lepidoptera. Considerable time 
has also been devoted to a study of over 8,000 Acalyptrate Diptera. 
Dr. Horn’s types of Coleoptera in the families Throscidae, Mala- 
chidae, Cleridae, Ptinidae, Lucanidae and Scarabaeidse have been 
located and numbered, as well as many of Grote’s types of Moths. 
The local collection is being entirely rearranged in cabinets in the 
Entomological rooms, where it is easily accessible and can be added 
to from time to time. The arrangement of the Odonata, Orthoptera, 
Lepidoptera, Rhopalocera, and part of the Heterocera and Coleop¬ 
tera has been completed. 
In the Orthoptera Mr. J. A. G. Rehn has rearranged the Blattidse 
and Dermaptera, the exotic Mantidse and a considerable portion of 
the North American Tettigoniidae. He has been engaged more or 
less regularly throughout the year, in conjunction with Mr. Morgan 
Hebard, in studying the Orthoptera collected by them in the south¬ 
eastern United States, together with material from the same area 
loaned by Cornell University, the State of Georgia and individual 
collectors. In this connection six genera were critically revised, 
and papers on them are in press or in process of completion. 
Mr. Rehn has also made considerable progress in the study of 
Brazilian Orthoptera received from various sources and has started 
upon the determination of African collections submitted by the 
Berlin Museum and German National Entomological Museum, 
from which the Academy will receive a duplicate series. A collec¬ 
tion of Phasmidse from New Guinea, sent by the Royal Zoological 
Society of Amsterdam, is to be worked up on the same terms. 
Mr. Hebard, who has spent much time studying his private col¬ 
lection, which is deposited at the Academy, has presented many 
specimens originally in the Bruner collection and has continued to 
maintain a preparator whose services have been given liberally to the
