PREFACE 



Early in 1921 the "Check-List of the Insects of Connecticut" 

 was published as Bulletin No. 31 of this Survey. Since then 

 many additional species and records have been collected, and the 

 present paper is a list of these additions together with the correc- 

 tion of certain errors discovered in Bulletin No. 31. Some of the 

 additions have been brought to light in the publication of Bulletin 

 No. 34, "The Hemiptera of Connecticut," and others in Bulletin 

 No. 39, "The Odonata or Dragonflies of Connecticut." 



In order to facilitate ready reference all names in the appendix 

 (pages 354-361) of Bulletin No. 31 are included in the present list, 

 but are excluded from the figures given in the second column of 

 statistics. Mere correction of the name of a species listed in 

 Bulletin No. 31 is not included. Hence the statistics given in the 

 following table may be considered a fairly accurate summary of 

 the species and varieties of insects that have been recorded from 

 Connecticut up to the time that this manuscript went to press, 

 May 1938.
