Editorial abstract of the fifth lecture on entomology by C. V. Riley, given at the Lowell In- 

 stitute, Boston, Mass., January U\ 1892. The economy and social life of the honey bee, and 

 the ant, and social wasps, were explained as the basis for a discourse on the development of 

 intellect and reason in insects, the author finding that as in man the higher intellectual devel- 

 opment and social organization have resulted from the long period of infantile dependence; 

 so in these insects the long period of larval dependence may be considered Hie primary cause 

 of their high intelligence and organization among insects.
