ing July and August adults appear in abundance and in the 

 latter part of the season adults only are observed. It seems 

 probable that a single generation for the year is the rule for the 

 species in Maine but this can not be stated with certainty. 



Idiocerus provancheri. 

 This species recorded as occurring in bogs was collected in 

 July in both nymphal and adult stages. A wider description of 

 the nymphs may be of service in further recognition of the 

 species.
