Cimicidae, 30 species and 183 specimens, 5 species totalling 

 about 100 specimens. 



Myodochidae, 14 species, over 20 specimens of one of them, 

 and a total of over 46 specimens. 



Coreidae, 7 species and 18 specimens. 



Tingids, 4 species and 35 specimens, some 32 being Galcatus. 



Reduviidae, 4 species and 5 specimens. 



Aradidae, 3 species and 8 specimens. 



Aquatics, all families, 9 species and 16 specimens, of which 

 nearly half were Gcrris rufoscutellatus. 



Miridae were not collected, as they were by far too dilapi- 

 dated to be of much service. 



The relative abundance of the families is what should be ex- 

 pected, in view of the fact that the Cimicidae are abundant in 

 numbers and strong fliers, and that the Myodochidae, next to 

 the Miridae, are the largest of the Heteropterous families and 

 most abundant as to individuals. No significance is to be at- 

 tached to the presence of water-bugs in the lake drift, as these 

 were probably drowned by their own element. Those on the 

 ocean shore, however, had got there by flight, and at the time 

 they were taken were quite lively. 



This is in the nature of a preliminary report, and it is hoped 

 that later study may be more enlightening as to the precise con- 

 ditions that determine these flights and their significance, as 

 well as the season of the year when they are most likely to 

 take place. 



Ecto or Endoparasitism? A plea for Greater Definiteness in the 

 Citation of Host Data in the Parasitic Hymenoptera. 



There is a strong tendency among students of parasitic Hymenoptera 

 and economic entomologists to ignore the matter of the exact relation 

 of the parasitic larva to the body of the host, i. e., whether it is ecto- 

 or endoparasitic. Many authors, even though they themselves rear 

 the parasites, are content to record merely "lired from." "reared from," 

 or "parasitic upon" such and such a host. Quite often, it is true, .me 

 can make a plausible guess from a knowledge of closely-related forms, 

 but this method cannot be universally applied with safety. 



The economic importance and the purely scientific value of bionomi- 

 cal studies in the parasitic Hymenoptera demand an ever-increasing 

 exactness of observation and record. Those who publish on material 

 which they have reared are usually in a position to state whether the 

 parasites are external or internal in habit. If this information is given, 

 the value of their contributions will be increased. C. H. RICHARDSON,
