222 ANNALS OF SCOTTISH NATURAL HISTORY 



Limnebius truncatellus, Thorns. Dumfries, Kirkcudbright, 



Wigtown. 

 Chffitarthria seminulum, Herbst. (Sharp and Lennon.) 



Helophorus tuberculatus, GylL Dumfries district (Lennon), two 

 specimens. 



H. porculus, Bedel. Dumfries, Kelton and Caerlaverock Salt 

 Marshes (Lennon). 



H. nubilus, F. Dumfries, Kelton and Caerlaverock Salt Marshes 

 (Lennon). 



H. aquaticus, L. Dumfries, Kirkcudbright ; a smaller form, pre- 

 sumably var. agnails, Thorns., although I cannot definitely 

 separate it from the type, is also common, especially on salt 

 marshes. 



H. viridicollis, Steph. ( = seneipennis, Thorns.}. Dumfries, Kirk- 

 cudbright ; H. strigifrons, Thorns., I have taken in Renfrew- 

 shire. It possibly occurs in the Solway district ; but until the 

 appearance of Mr. Edwards's paper on the ' British Helophori ' 

 ("EMM.," ser. 2. xix. Oct. 1908), I had not attempted to dis- 

 tinguish it. I am not yet clear in my own mind that it is 

 worthy of specific distinction. 



H. dorsalis, Marsh (=Mulsanti, Rye}. Dumfries, Kelton; 

 Kirkcudbright, Preston Merse. 



H. brevipalpis, Bedel. Dumfries, Kirkcudbright, Wigtown (J. G. 



Gordon). 

 H. arvernicus, Muls. Dumfries, R. Lochar ; Kirkcudbright, 



Cargen Burn. 

 Hydrochus brevis, Herbst. Kirkcudbright, Maxwelltown L. 



(Lennon). 

 H. angustatus, Germ. Kirkcudbright, Maxwelltown L. ; one only, 



(Lennon). 

 Henicocerus exsculptus, Germ. Kirkcudbright, R. Nith, R. Ken ; 



not common. 

 Octhebius marinus, Payk. Dumfries, Kelton and Caerlaverock 



Salt Marshes ; Kirkcudbright, Preston Merse. 

 O. pygmaeus, K-- Kirkcudbright, Dalbeattie, Castle - Douglas ; 



scarce. 

 O. bicolor, Germ. Dumfries, Kelton ; not common. 



O. rufimarginatus, Steph. Kirkcudbright, Cargen Burn (one 

 specimen only) ; Lennon (MS. list) speaks of it as very rare, 

 and there is only one specimen in his Collection. 



O. auriculatus, Rey. Dumfries, Kelton, a few specimens, but it 

 has not been searched for !
