584 PROCEEDINGS OF THE ACADEMY OF [DeC, 



In the order Diptera the famihes Tipulidae and DoHchopodidse 

 have been rearranged. 



In the Coleoptera the labelling of the Horn types has been con- 

 tinued and the rearrangement of the family Scarabseidse completed. 



In the Hymenoptera, the rearrangement of the Ophionini and 

 Pimplinse has been finished. 



In the Lepidoptera, the Welles collection was safely transported 

 from Ehvyn, Pa., and the following families rearranged: Agrotinse, 

 Syntomidse, Saturnidse, Lycsenidse, and the exotic Nymphalidse and 

 part of the Pieridse. 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 will 

 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-
