2. D. Fallciil L\v. : tliu dcscripLioii uL" 1). nUjripes " from Mr. Dalo'.s 



collection " ill Walker's Ins. Brit. Dipt, must refer to B. 

 Falleni or D. Meujenii. I Lave seen Dale's specimeu, which 

 was takeu at Glauville's Woottou on August 2ncl, 1839, and 

 1 have a note that it is not D. Meir/enil. D. Falleni may 

 therefore be acknowledged as British, while the closely 

 allied D. Mcigenii is also very likely to occur. 



3. D. melanopiis Meig. : 1 have seen only two males of this species, 



which 1 took in the New i'orest on June 2Gth, 1S72. 



4. D. picipes Meig. : this is the I), fastuosus of Haliday, and occurs 



in various localities over all parts of Britain. 



5. D. campcstris Meig. : not uncommon from Penzance to Suffolk 



and Norfolk. It is easily distinguished in both sexes by the 

 two pre-apical spines on the middle femora, while occasionally 

 the hind femora also bear two. 



6. D. planitarsis Fall. : very rare as far as my expex'ieuce goes, but 



that may be because it is probably a spring species, Col. 

 Terbury gave me a male taken at Lyndhurst on May 1st, 

 1S97, and I have seen it from Aberdeen. I cannot trace 

 Kowarz's distinctive character of the female, based upon 

 more than one bristle beneath the middle tibiae. 



7. D. h'pidiis Stjeg. : it is sti*ange that Haliday never recognised this 



rather common species as British. I have taken it from the 

 south of England to the north of Scotland. 



8. D. LA.TICOLA n. sp. : ^ . affiuis Z). plcipcdi, sed facie magis des- 



cendente, pedibus anterioribus magis ferrugineis, et costa 

 ubi vena subcostalis excipit modice sed distincte incrassata. 



(J . Face almost dcscendiug to the level of the bottoui of the eyes (and jct the 

 species is apparently a Dolichopus ratlier than a Hygroceleuthus), moderately broad 

 as it is hardly more than three times as long as broad, white but hardly silvery ; 

 frons shining bluish but dusted ; palpi blackish-brown ; postocular cilia all black. 

 Antenna) wholly black, not short, third joint pointed and forming an almost 

 equilateral triangle. 



Thorax dusty blue-black ; prothorax with delicate pale pubescence. 



Abdomen, when viewed from behind, greyish-green, and not sliining until the 

 blue-green dorsal part of the Cfth segment ; hind margins of tlio segments con- 

 spicuously blackish. Hypopygium shining black but dusted beneath, long and 

 narrow as it reaches almost to the base of the third ventral segment ; lamella} dull 

 pale yellow with a rather narrow black end ; when viewed from beneath these 

 lamella; have a narrow black margin on the outside and liave the fringe curling 

 inwards as well as outwards, on the outer side of the lamellae there is only a short
