The President exhibited numerous specimens of the Cicada sep- 

 tendecem of North America, in the various states of &^'^, larva, pupa, 

 and imago ; and, by his permission, an extract from a Letter which 

 he had received from Dr. Harlan, of Philadelphia, was read ; from 

 which it appeared that the larvae reside under ground, although the 

 eggs are deposited in slits which the parent flies make with their 

 ovipositors in the twigs of trees. On making their escape from the 

 earth they are greedily feasted upon by birds, and it had been noticed 

 that chickens eating them deposited eggs with colourless yolks ; their 

 septendecenary appearance was also confirmed by the writer*.
