A FORTNIGHT in SCOTLAND in SEARCH of AQUATIC RHYNCHOTA. 

 BY G. W. KIEKALDY, F.E.S. 



I arrived at Perth early on August 20th, and had the pleasure of 

 making the personal acquaintance of that indefatigable collector, Mr. 

 T. M. McGregor. As it was raining nearly the whole day, I spent 

 the greater part at the Natural History Museum, which is under the 

 Curatorship of Mr. A. M. Eodger. An account of this interesting

 development of the black pigment, is rastrate. I have never before 

 seen a similar case in the Corixidce. In Methven Bog a single 

 example of Hydroessa {= Microvelia) pygmeea was taken ; although 

 Mr. McGregor has captured it before, it has not yet been recorded, 

 with the exception of Edinburgh, from Scotland. 



On the 22nd it was pouring, and I therefore resorted to the
