660 PROCEEDINGS OF THE ACADEMY OF [DeC, 



Dr. Pilsbry has completed the publication of a monograph of the 

 Hawaiian tree snails, Achatinsllidx, 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 

 Gyrinidae, Hydrophihdse and part of the Scarabseidse among the 

 Coleoptera and the exotic and American Syntomidse, 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 Throscidse, Mala- 

 chidse, Cleridse, Ptinidae, Lucanidse and Scarab2eida3 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 Mantidae 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 ^ame 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 Phasmidae 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 libci-ally to the
