Notes on the Life-history of an Endemic Hemerobiid 



(Nesomicromus vagus Perk.). 



BY F. W. TERRY. 



During a collecting trip up the local valley of Palolo last March, 

 several eggs of this small Hemerobiid were found on the leaves of 

 a composite which was infested with aphides. From these eggs 

 several larvae hatched, from which adults were finally bred.* 

 The young emerged Mar. 5th, '07., feeding readily on aphides of 

 various species, becoming fully-fed Mar. 14th. They commenced 

 spinning cocoons the following day, and pupated Mar. 16th, 

 emerging as adults Mar, 24th. 



The total period occupied from eggs to adult being about 3
