OCCURRING ABOUT IIOLYWOOD. 163 



positively say, without a more detailed examination than I have 

 materials for, possessing only a pair, and the fragments of a third 

 wanting the head. These were all taken at Holywood, about 

 eight years since. The trophi are prominent, with fleshy lips, and 

 long exserted linear palpi. A single Spania occurred this summer 

 near the waterfall in the Devil's Glen, but as it escaped from me, 

 I cannot identify the species. 



Medeterus alpinus. Nigro-ceneus,2)edibusferrvgineis, alisfuU- 

 ginosis jilcigU' hyalina, hypostomate argenteo. Mas. Oculis 

 conjluentibus, alts intus angustatis. 



(To division B.) A minute species, half the size of M. curvipes : 

 mouth prominent, silvery: eyes of the male contiguous, of the 

 female divided by a very narrow line : front steel blue : body 

 metallic, greenish black : legs ferruginous, thighs above with a 

 dusky line, feet brown : wings dusky black, the disk whitish 

 hyaline, transverse nervure and a dot on the 4th dusky. In the 

 male the wings are much narrowed from the 5th nervure to the 

 base, the tip is more determinately coloured, and the nervures 

 suiFused with black. 

 Near the summit of Sliebh Donard, upon spots of black 



springy peat; elevation nearly 3000 feet. In moory uplands 



of Wicklow. 



Porphyrops riparius. 



The male, described under this name in the 19th number of the Zoo- 

 logical Journal, is the other sex of P. rufipes there mentioned as a 

 native ; but as it does not exactly accord with Meigen's description 

 of the male of that species, the synonym may be doubtful. 



P. pumilus. 



The males of this and some cognate species, have no spine on the 

 hind metatarsus : my divisions A and B, should be re-united as they 

 stand in Meigen, (and probably the genus Rhaphium reduced to 

 the same ;) but P. flavicollis seems to differ from the rest by its 

 reflected hairy palpi, &c. 



Dolichopus jucundus. Viridi-ceiieus, incisuris nigris, antennis 

 bast riifis, coxis anticis pedibusque jmllidis, tarsis apice 

 nigris, alarum nervo quarto rectangulatim fracto. Mas. 

 Femorihiis iruberbibus, larnellis longius ciliatis. 



Resembles D. nitidus (Fallen), but the third joint of the antennae 

 is shorter and blunt, black at the end, the rest ferruginous with a
