The sequence of the Orders is somewhat unusual, and we are sur- 

 prised that no mention is made of the Neuropterous families Psocidas, 

 Perlidae, and Ephemeridse. 



Additional value to this important work is the inclusion therein of 

 a large Bathy-Orographical map of the Clyde Basin, which was 

 specially prepared for the Meeting of the British Association. 



The Stridulatinq Organs of Waterhugs (Bhipichota), especially of Corixid(B. 



By G. W. KiRKALDY, F.E.S.' In "the ' Journal of the Quekett 



Microscopical Club, April, 1901. 

 After passing carefully in review the observations and opinions of 

 writers who have referred to this subject, from Frisch, in 1740, to 

 Handlirsch, in 1900, the author states his belief that stridulatioh is 

 brought about in these insects by a method different from any 

 previously suggested. " In 1874 Landois described the ' comb ' on 

 the anterior tarsus of the male in Corixa, and its action (as he thought) 

 on the last segment of the rostrum." Kirkaldy, however, brings to 

 notice the fact which he has discovered, that there is " on the inner 

 surface of the femora (in the males only), near the base, a specially 

 modified area of minute chitinous pegs arranged in regular rows." 

 These form the str 'ululating area. In the author's opinion " the 

 ' comb ' of the left tarsus is drawn somewhat obliquely across the 

 femur of the right leg, or vice versa," and in this way stridulation is 

 brought about. This paper, which extends to fourteen pages, contains 

 much valuable information on the structure and stridulation of water- 

 bugs, the text being illustrated by two clear plates containing details 

 from no fewer than twenty-six different species. w j Lucas

 One hundred and twenty-eight parasitic Hymenoptera are recorded 

 by Mr. Ashmead, doubtless a small proportion of the forms actually ex- 

 isting in the Hawaiian Isles ; of these, eighty-seven are new to science. 

 Of the fourteen families represented, all have a wide geographical 

 range ; the 128 species are distributed among sixty-nine genera, of
