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 Musca domestica was mentioned. If the 
flies are boiled in a solution of caustic potash the ovipositors of 
the females will be extended. 
BROOKLYN ENTOMOLOGICAL SOCIETY. 
At the annual meeting, held January 11, 1912, resolutions 
of sympathy were adopted for Prof. John B. Smith, whose
