needed for the national collection were taken. In ISIay Mr. Field spent 

 12 days in the entomologically neglected area of western Virginia and 

 West Virginia collecting information, especially on the extent of the 

 ranges of boreal species in the southern mountains. 



At the close of the year Dr. O. L. Cartwright, curator of Coleoptera, 

 was on a trip to London and Paris to study type specimens of scarab 

 beetles of the Bahamas and Micronesia. 



Dr. Paul J. Spangler, associate curator of Coleoptera, spent 7 weeks 

 during July and August in Mexico and southwestern United States 

 collecting much needed material for his investigations on water beetles. 

 So little is known about the merging of the Nearctic and Neotropical 

 Zones in Mexico that all expeditions to this area are pointed toward the 

 elucidation of this factor. Not less than 6 of the genera collected 

 represent new records for Mexico and not less than 20 species are new 

 to science. Larvae for nearly all the species were collected, and all the 

 information on immature forms is new. Specimens of semiaquatic 

 beetles of the very rare family Georyssidae were collected in quantity. 



Kalph E. Crabill, Jr., curator of Myriapoda and Arachnida, was 

 in Europe at the beginning of the fiscal year and staj^ed there until 

 mid-August, during which time he visited the Zoologische Samlung 

 des Bayerischen Staates, Munich, and the British Museum (Natural 

 History) for thQ purpose of studying typical and ordinary chilopod 

 specimens. In upper Bavaria and northern Austria he undertook 

 four collecting trips which netted some 1,200 specimens, including some 

 topotypes and a host of species not previously represented in the 

 national collections. 



From mid-July to mid-August, Dr. Oliver S. Flint, Jr., associate 

 curator of neuropteroids, was on a field trip to the islands of Jamaica, 

 Dominica, St. Lucia, and Grenada, conducting studies on the Antillean 

 caddisfly fauna. During 4 days spent on Jamaica and about a week 

 each on the other islands he collected 2,000-3,000 insects, of which 500 

 or more are Trichoptera. In April and June he was back in Dominica 

 as a participant in the Bredin-Archbold-Smithsonian biological sur- 

 vey of that island. Dr. Flint completed two papers dealing with 

 certain species of Nearctic Trichoptera in the collection of the Museum 

 of Comparative Zoology, Cambridge, and new species discovered in 

 the United States. 



Jason R. Swallen, chairman of the department of botany, visited 

 South Africa in September and October at the invitation of the 

 National Botanic Gardens of South Africa to join in the Golden Jubi- 

 lee Celebration of the Gardens. The celebration included over a 

 month's tour of the country, which afforded an opportunity to collect 

 about 200 specimens of grasses, including a number of species new to 

 the National Herbarium.
