worked during the whole term in the Entomological Department 

 on Diptera and Hemiptera, and Mr. G. Jack has continued his 

 biological studies for a part of the time. 



The Assistant has rearranged the Lepidoptera of North Amer- 

 ica, and a part of the exotic Lepidoptera. He has completed 

 the exhibition boxes for the South American, and partly for the 

 Asiatic Fauna. Among the Neuroptera, the large family of 

 Myrmeleon was studied and described, especially the North 

 American species, which are ready for publication. 



The beginning of a Monograph of Hemerobidas, two papers, 

 is printed in the Proceedings of the Boston Society of Natural 

 History, and the Palpares and Acanthaclisis in the Canadian 

 Entomologist, four papers, with the title, " Stray Notes on Myr- 

 meleon." Several papers are published in the Entomologica 

 Americana. 



The Assistant visited Washington, Baltimore, Philadelphia, 

 and New York, to study the entomological collections of those 

 cities, and to obtain some material for a paper on Mr. T. Glover, 

 and his large but little known work, which he published in the 

 Stettiner Entomologische Zeitung.
