18. D. popularis Wied. : the most beautiful of the species as yet 



recorded from Britain. 1 have met with it locally in numerous 

 localities from Dawlish to Tongue. 



19. D. signatus Meig. : moderately common from Lyndhurst to 



Lairg. 



20. D. urhanus Meig. : readily distinguished in both sexes by its 



black hind tibiae. Moderately common from Lyndhurst to 

 Inveran. 



21. D. trivialis Hal. : very common from Penzance to Aberlady. 



22. D.festivus Hal. : also common from Penzance to Dolgelley. 



23. D. virgultorum Walk. : this and the next species are distinguished 



by their almost whitish-yellow legs, and by an obvious spine 

 on the basal joint of the middle tarsi ; they also seem to me 

 to avoid marshy districts and occur on shrubs growing on 

 the dry banks at the sides of country lanes. Both species 

 are rare, but D. virgultorum has occurred to me at various 

 localities in Sussex. 

 2-t. D. arbustoruin Stann. : this species occurs in similar localities to 

 the previous one in Hampshire and Sussex, though in very 

 restricted localities. 



25. D. nitidus Fall. : this and the next species are well distinguished 



from all known British species (except Hygroceleuthus dia- 

 detna) by the rectangular twist of the discal vein. Z>. nitidus 

 is by far the less common of the two, but I have taken it 

 in the Norfolk Broads, at Sutton in Lincolnshire, and in 

 numbers at Rydal. 



26. D. griseipennis Stann. : common from Penzance to Aberlady. 



27. D. signifer Hal. : recorded by Haliday in Walker as from "a 



sandy islet off the western coast " of Ireland ; a reference to 

 Haliday's original description in Ann. Nat. Hist., ii, 184, 

 November, 1838, gives this locality, " on a sandy islet in 

 Roundstone Bay ;" I find that Eoundstone Bay is a small 

 bay off Connemara. Although the species is well recognised 

 over most of Central Europe, it has never since been re- 

 corded as British again until now, when I record two male 

 specimens taken by Mr. C. Gr. Lamb at Padstow in Cornwall 

 in September, 1903, and in 1904. 



28. D. clavipes Hal. : Haliday states that this species is " not rare 



on the sea coast (E. S. I.) ;" I have met with it only at
