56 REPORT OF NATIONAL MUSEUM, 1924 



the material in the families Bupresticlae, Cerambycidae, Elateridae, 

 and Eucnemidae, has been arranged and placed in trays by W. S. 

 Fisher, J. A. Hyslop, and H. S. Barber. Dr. A. Boving has fin- 

 ished the arrangement of the collection of Palearctic coleopterous 

 larvae, as well as the entire larval collection of Carabidae, half of 

 the Chrysomelidae and part of the Curculionidae. William Schaus 

 has continued arranging and identifying the Macrolepidoptera so 

 far as drawers and cases permitted. A rearrangement has been pos- 

 sible in the Palearctic part of the geometrid subfamily Larentiinae, 

 the South American Epipaschiinae, the Old World Pieridae, and 

 Hypsidae. H. G. Barber has arranged most of the Hemiptera of 

 the family Reduviidae, and John R. Greely, under the supervision 

 of W. L. McAtee transferred and arranged the Hemiptera of the 

 Baker collection. The collection of aphids is still housed in the Bu- 

 reau of Entomology Building. P. W. Mason, under Dr. A. C. 

 Baker's direction, has rearranged and revised the collection in two of 

 the smaller genera. The coccid collection was removed from the 

 bureau building early in 1924 to a room on the third floor of the 

 Natural History Building, where it is now under the care of Harold 

 Morrison, who has revised and arranged the subfamily Ortheziinae. 

 C. T. Greene has continued his work on the Diptera and placed the 

 adults of the families Bombyliidae, Asilidae, Phoridae, Conopidae, 

 There vidae, Platypezidae, and part of the Tabanidae in trays and 

 arranged the collection. S. A. Rohwer reports that in the section of 

 Hymenoptera as much progress in arranging the collection was 

 made as was possible with the equipment, as all the drawers and 

 trays which could be spared for rearranging the material were used, 

 and more could have been utilized if they had been available. The 

 present condition of the insect collections is good, and there is little 

 or no infestation with museum pests. 



In the division of echinoderms a large number of specimens have 

 been placed in permanent containers and transferred to the study 

 collections and much previously unidentified material has been de- 

 termined. Practically all the material received in current accessions 

 was indentified and added to the study series. Thanks to the volun- 

 tary work of Miss Elisabeth Deichmann, of Copenhagen, who studied 

 the holothurians of our collection for more than half a year, all of 

 our unidentified material in this difficult group has been determined. 



Curatorial work in the division of plants in connection with the 

 upkeep and increase of the herbarium has continued satisfactorily 

 during the past year. In the course of a general review of West 

 Indian and Costa Rican ferns, Doctor Maxon has reidentified a con- 

 siderable amount of herbarium material, and Mr. Standley has per- 

 formed a similar service in the case of many groups of flowering
