The Early Stages of the Life History of 

 Polystoechotes Punctatus Fabr.,* 



By Paul S. Welch

 of the Hemerobiidae. Thus far only two species have been re- 

 ported from North America, namely P. punctatus, Fabr. and P. 

 vittatus Say. The latter appears to have been reported only from 

 New Jersey and Pennsylvania, but the former is said (Banks, 

 '05, p. 28) to occur "all over the northern half of our country and 

 extending southward in the mountains, as into North Carolina, 

 New Mexico and Arizona; more coinmon in the northwest than 

 elsewhere." P. punctatus is not only widely distributed but it 

 also occurs in some localities in great numbers during certain 

 parts of the summer, hence it seems strange that the immature 

 stages of this attractive insect should remain uiiknown so long. 

 The adult has been well known for many years, but information 

 concerning the life history has apparently been lacking. The 

 only account of this insect known to the writer which contains 

 any data at all on any of the stages of the life history is that of 

 Needham ('01, p. 551) in which the eggs are described as follows: 

 "I obtained some of the eggs in July by confining some of the 

 females of Polystoechotes in a pasteboard box. The eggs were
