by nearly all the free-ranging butterflies, and by many strong- 

 flying noctuids. Utetheisa bella was not uncommon in the drift- 

 line on Aug. 23rd. 



Hymenoptera and Lepidoptera I did not save for determina- 

 tion owing to their dilapidated condition. The former group is well 

 represented by Bombus, Apis and several Ichneumonids and a few 

 saw-flies. 



The true Neuroptera are represented only by the delicate 

 lace-wings. As determined for me by Mr. Roger C. Smith, these 

 are. —

Of Trichoptera, the pupal skins of three species, all unde- 

 termined, appeared abundantly in both flotsam and drift, the dates 

 of maximum accumulations being Aug. 1st, 8th, 24th and 25th. 

 The one common adult of the drift-line was Agrypina curvata Banks 

 — not"Glossosoma sp.?" as reported in my first paper (1900) on 

 Banks' determination. Neuronia concatenata Walk, once appeared, 

 a single specimen, and also an undetermined Leptocerus. 



Of Odonata, there are always present a few large dragon- 

 flies, species of i^schna and Anax, and often there are smaller 

 ones, Sympetrum, Lestes, and Nehalennia. 



The Orthoptera of my drift collection, numbered but seven 

 species. The three which numbered five or more specimens each 

 (as determined by Mr. H. H. Knight) were: — 



Telligidea lateralis Say. VI, 13-148, of which but 34 were females. 

 Melanoplus femur-rubrum DeG. VIII, 23-24, of which one was a female. 

 Choriophaga viridifasciata DeG. VI, 13-5, all brown females. 



The Ephemeridae are represented abundantly in both flotsam 

 and drift by innumerable cast nymphal skins, and by much fewer 

 adult specimens. I have seen acres of the water surface along shore 

 covered in scattered patches with floating felted masses of the skins 

 of Ephemera simulans. On the 21st of July, 1906, there occurred 

 a peculiar drift, that was composed almost entirely of the wings 

 and other disintegrated fragments of adult Mayflies. It lay in 

 grayish, curving lines, so thin it might have been easily overlooked, 

 spread over the sand at the farthest reach of the gentle waves that
