Living Myrmecina graminicola. — Mr. Donisthorpe ex- 

 hibited a colony of Myrmecina graminicola, Latr., whicli he 

 had kept in captivity for over five years, having taken it when 

 it was an incipient colony at Box Hill, May 1, 1910. His object 

 in showing this colony was to call attention to the number of 

 winged females which had been reared in the nest this summer. 

 He stated that over 50 such females and one male had been 

 produced, and that a number of the former had now removed 

 their wings, as do fertilised females. It was a very remarkable 

 fact that only once previously — when the late Lord Avebury 

 had some winged females produced in an observation nest of 

 Formica fusca — have females ever been reared from eggs laid 

 in captivity. 



Mr. Donisthorpe stated that the ants liad been supplied 

 with large quantities of animal food (gnats, and other flies, 

 other ant larvae and pupse, etc.), which had no doubt some- 

 thing to do with the rearing of the females, but as all his other 

 observation nests had been treated in the same manner and 

 had not produced such females, this could not be the only 

 explanation.
