SECRETARY'S REPORT 45 



a specimen of Pieris virginiensis Edwards, one of the rarest of eastern 

 butterflies. Over 100 mature larvae of Ewphydryas 'phaeton Drury 

 and a good series of GlaucopsycTie lygdamus Dbldy., another early- 

 spring rarity, also were collected. 



During the latter part of August Dr. Donald R. Davis, associate 

 curator of insects, conducted studies on Microlepidoptera in the 

 Tenkiller Lake district of Oklahoma. As this is an area practically 

 unknown entomologically, these studies Avere particularly significant 

 in producing information on distribution, ecology, and new species. 

 Prior to this, in July, on a visit to the Dismal Swamp area of Virginia 

 in company with Dr. Flint, Dr. Davis collected 300 specimens of 

 Microlepidoptera, along with a sizable sample of leaf miners. Three 

 species of leaf miners were reared, and leaves mined by several addi- 

 tional species were collected. 



Associate curator O. L. Cartwright, who in May accompanied Dr. 

 Spangler to the vicinity of Oakland in Garrett County, Md., collected 

 specimens of seven species of Scarabaeidae, including three rare 

 species, the basis for new Maryland State records, and one species 

 (nine specimens) apparently new to science. 



During July Dr. Donald F. Squires, associate curator (now curator) 

 of marine invertebrates, was in New Zealand conferring with officers 

 of the New Zealand Oceanographic Institute regarding the identifica- 

 tion and study of deep-water coral banks, and with the New Zealand 

 Geological Survey staff regarding the occurrence of such banks as 

 fossils. At the Auckland Museum and Institute he studied recent 

 collections of corals, particularly those made by fisheries research 

 vessels. He also examined outcroppings of fossil deep-water coral 

 banks at two localities in Wairarapa. 



In November, while participating in the annual meetings of the 

 Bahamas National Trust, Dr. Squires conducted preliminary explora- 

 tions, with other members of the Trust, of the reef tracts at Lyford 

 Cay, New Providence Island. 



From late in March to early in May, Dr. Squires carried out field 

 work on R/V Chain of the Woods Hole Oceanographic Institution, as 

 part of the international Equivalent I operation, in the area from 

 Recife, Brazil, to Trinidad and east to longitude 25° W. He collected 

 samples and made numerous bathymetric observations on the struc- 

 tures knowTi as shelf-edge prominences off the Orinoco River Delta. 

 Also, he made collections of corals from 40 to 200 fathoms in the 

 vicinity of St. Paul's Rock and in the approaches to Paramaribo, 

 Surinam. 



As a participant in the International Indian Ocean Expedition from 

 the middle of January to the middle of March, Charles E. Cutress, Jr., 

 associate curator of marine invertebrates, visited the Indian Museum
