of the German Central African Expedition, loaned to him for 

 study by the Berlin Museum, and on which he had spent the 

 greater portion of the past year. The series contained two 

 hundred and twenty-six species, of which eleven genera and 

 subgenera, and eighty-one species proved to be new. An 

 analysis of the relationship of the Orthopterous fauna of the 

 Central African lake region and Uganda showed that the 

 greater portion of the species not peculiar to the region were 

 of West African forest region relationship, the eastern steppe 

 element being less numerically. This proportion has been 

 found to be carried out in a number of groups of animals and 

 plants similarly analyzed. Some idea of the richness of 

 species in certain localities was given, and a number of strik- 

 ing species from the collection exhibited. He also exhibited 

 a collection of Orthoptera from Egypt, sent for study by 

 Edgard Chakour. 



Dr. Calvert made some remarks on the collection he had 

 presented, and said he had been giving a course at the Univer- 

 sity of Pennsylvania on the transmission of disease to human 

 beings by insects. He gave a history of the disease, nagana, 

 conveyed to animals by Glossina morsitans and brevipalpis, and 

 sleeping sickness conveyed by G. palpalis. A rapid way to de- 

 termine the sex of Mnsca doinestica was mentioned. If the 

 flies are boiled in a solution of caustic potash the ovipositors of 

 the females will be extended.
