584 PROCEEDINGS OF THE ACADEMY OF [Dec., 
In the order Diptera the families Tipulidse and Dolichopodidae 
have been rearranged. 
In the Coleoptera the labelling of the Horn types has been con¬ 
tinued and the rearrangement of the family Scarabaeidae completed. 
In the Hymenoptera, the rearrangement of the Ophionini and 
Pimplinae has been finished. 
In the Lepidoptera, the Welles collection was safely transported 
from Elwyn, Pa., and the following families rearranged: Agrotinae, 
Syntomidae, Saturnidae, Lycaenidae, and the exotic Nymphalidae and 
part of the Pieridae. The genera Kallima, Papaipema and Autographa 
were also rearranged. 
In the Orthoptera the series of the genera Orchelimum, Cono- 
cephalus and Atlanticus have been rearranged in the new type of 
double box, which was all the general rearrangement possible during 
the year with the few boxes available. 
Mr. J. A. G. Rehn spent two months in the field in company with 
Mr. Morgan Hebard, working in the Gulf States from northern 
Florida to eastern Texas. The trip, which was highly successful, 
resulted in securing a very large series from the most neglected 
portion of the eastern States, of which collection the Academy wall 
receive one-half. 
Mr. Hebard has continued his studies, based very largely on the 
material in his own collection, here deposited, and in the Academy 
series. He has also continued to maintain a preparator, whose 
services as in the past have been given very liberally to the Academy. 
By his aid it was possible to have mounted practically all the 
previously unmounted Orthoptera owned by the Academy. In 
collaboration with Mr. Hebard, Mr. Rehn has completed the final 
portion of an extensive paper on the Orthoptera of the southeastern 
United States, which was based largely on the field work conducted 
under the auspices of the Academy. The same authors have made a 
synoptical study of the genus Atlanticus and progress has been made 
on a similar treatment of the genus Mermiria. 
Mr. Rehn has been and is at present engaged in studying extensive 
Brazilian collections, of which the Academy will receive the first 
set of such material as it does not already possess. He has also 
made some additional progress with the study of the extensive 
African collections placed in his hands by other institutions, but 
owing to the greater urgency of other work this has been temporarily 
laid aside. 
A large number of visiting entomologists have studied the collec-
