LECTURES" 15- 
A VALUABLE collection of the co-types of the ants obtained by Pro- 
fessor Filippi Sylvestri of Naples in a‘trip across South America some 
years ago has been presented to the Museum by the collector. The: 
corresponding type collection was described by Professor Carlo Emery 
of Bologna. 
THE great Scudder collection of fossil ants from Florissant, Colorado, 
has been loaned to the Museum for study and description. The col- 
lection consists of more than 4,000 specimens representing about 40: 
species. None of these species has been described, and there is ample- 
material for the work. ‘The specimens are almost entirely males and 
females which dropped into the Tertiary lake of Florissant while on 
their nuptial flight. Practically no workers are represented in the: 
series.
