 the muscoid flies of the Old World except Europe; and studied the 

 species of botflies of the genus Cuterehra, in collaboration with 

 Maj. E. E. Austen, of the British Museum. C. T. Greene worked 

 on a revision of the genus Anastrepha of the family Trypetidae, of 

 definite importance because of the discovery of members of the genus 

 in the southernmost parts of the United States, including Florida 

 and the Brownsville area in Texas. Foster H. Benjamin completed

 Mediterranean fruit fly. Dr. Alan Stone undertook a critical revi- 

 sionary study of the genus Tabanus. Dr. A. G. Boving prepared

 and Nicobium castaneum. One paper, describing the larva of the 

 coccinellid beetle Decadiomus pictus, was published. L. L. Buchanan
