222 ANNALS OF SCOTTISH NATURAL HISTORY 



Limnebius truncatellus, llioms. — Dumfries, Kirkcudbright, 

 Wigtown. 



Chfetarthria seminulum, Herbst. — (Sharp and Lennon.) 



Helophorus tuberculatus, Gyll. — Dumfries district (Lennon), two 

 specimens. 



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

 ^Marshes (Lennon). 



H. nubilusj F. — Dumfries, Kelton and Caerlaverock Salt Marshes 

 (Lennon). 



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

 sumably var. csqualis, Thoms., although I cannot definitely 

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

 marshes. 



H. viridicoUis, Steph. ( = aeneipennis, Thorns.). — Dumfries, Kirk- 

 cudbright ; H. stn'gifrons, Thoms,, 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, AIa?'sh ( = Mulsanti, J^ye). — Dumfries, Kelton ; 

 Kirkcudbright, Preston Merse. 



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

 Gordon).

 Cargen Burn.

scarce. 

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

 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 !
