Clearly, Dr Lintner found this species in far greater abundance at Long 

 lake, Hamilton co, N. Y. in August 1885 1; for he wrote of it, " Hundreds 

 could be seen resting on the parlor walls. '^ 



But two hemerobian genera have been accounted aquatic hitherto. 

 These are O s m y 1 u s , a European genus, whose life history has been 

 fully made known by Hagen and Brauer, and Sisyra, whose larvae, 

 common in fresh-water sponges in Germany and in England, seem to 

 have been determined by exclusion ; at least I have been unable to find 

 any account of the rearing of the larvae or any description of the pupae 

 or the cocoons. I reared many of the larvae at Saranac Inn during the 

 past season; and bred also the American genus C 1 i m a c i a , of whose 

 habits nothing seems to have been known hitherto. It also is aquatic, 

 and, like Sisyra, lives on fresh-water sponges. 



Larvae and pupae of these two genera may be separated as follows. 



Larvae 



a Setae on the dorsum of the thorax pedunculate (i. e. the setigerous tubercles 



elevated considerably above the level of the integument) Climacia 



aa Thoracic setae sessile Sisyra 



Pupae 



a Tips of the fore tarsi extending posteriorly beyond the apices of the maxillary 

 palpi ; the fifth segment of the latter less than twice the width of the fourth . 

 Outer covering of pupal case of open regular hexagonal mesh 



Climacia 



aa Fore tarsi and palpi with apices about on a level; fifth segment of the 



maxillary more than twice the width of the fourth. Outer covering of 



pupal case close woven Sisyra
