of it has been transferred from miscellaneous containers into stand- 

 ard vials. To facilitate identification work in the Orthopteroid 

 insects, A. N. Caudell arranged a systematic series of the North 

 American forms in the families Forficulidae, Blattidae, Mantidae, 

 Grylliidae, and the subfamilies Tettiginae, Oedipodinae, and Truxa- 

 linae of the Acrididae. Dr. T. E. Snyder continued his study of 

 white ants, and rearranged a part of the collection with addition of 

 interesting accessions in this order. W. S. Fisher rearranged all 

 of the West Indian beetles of the subfamily Lamiinae, and in addi- 

 tion placed other material of this group in trays. Dr. M. W. Black- 

 man completed arrangement of the bark beetles of the superfamily 

 Scolytoidea in standard trays and drawers. The bark beetles are 

 now arranged in a systematic manner so that all of the material of 

 the group is readily accessible to specialists who wish to consult it. 

 Dr. W. Schaus continued rearrangement of the exotic Macrolepid- 

 optera so far as is practicable with the drawers and cases available. 

 During the year he devoted much energy and effort to the securing 

 of subscriptions for the purchase of the Dognin collection, and 

 succeeded in obtaining sufficient money to assure the acquisition of 

 this collection. In May he arranged for the purchase, and in June 

 sailed for France to pack and ship the material. He was accom- 

 panied by J. A. Barnes as assistant. C. Heinrich and A. Busck have 

 continued their studies and rearrangement of the collection of 

 Microlepidoptera. The collection of larval Microlepidoptera of 

 the families Noctuidae, Pyralidae, Saturniidae, Sphingidae, and 

 Geometridae, have been catalogued and labeled. The Olethreutidae 

 from the Fernald collection have been added to the regular collection 

 and the group completely rearranged. Mr. Heinrich submitted a 

 manuscript describing new forms and revising those previously 

 described. 



In the section of Hemiptera the Mexican and Central American 

 Membracidae have been fully identified and the collection re- 

 arranged, the North American Telamonini, Cryptostemmatidae, and 

 Ploiariinae have been revised and rearranged, and also the Neotropi- 

 cal Coreidae in so far as they are identified, all by W. L. McAtee 

 and J. R. Malloch. H. G. Barber identified many of the bugs of the 

 family Lygaeidae. Dr. H. G. Dyar and R. C. Shannon have re- 

 studied and rearranged -the North American flies belonging to the 

 family Simuliidae and have completed a revision of this group. 

 C. T. Greene has continued transfer to the tray system of certain 

 groups of flies in which he is especially interested. He continued 

 his arrangement of the collection of immature stages of Diptera 

 and reports that of the 61 families of Diptera, the Museum now 

 contains representatives of 54, in this stage of growth. The na-
