Leia nasuta {Mycetophila id., C. 1173. 17^). 



L. fusca abdomine albido-piloso ; antennis basi pedibusque flavis ; 



trochanteribus nigris, m.f. Long. 2-J- — 8 lin. 

 Not uncommon about rivulets at Holywood. 

 Add. Wings as in Mycetophila, fig. 21. (Meig. 1. pi. ix.) 

 The face of the male is usually armed with a deflected horn 

 or spine. There are three ocelli nearly in a line on the vertex, 

 which determines its place in the genus Leia, Mycetopldla 

 flavipes of Macquart (S. a B. i. 130) seems nearly allied. 

 Limnobia Aegle, C. 1157. 37". 



This is identical with Idioptera pulchella {Limnobia id. 

 Meig. vi. 275. Idioptera maculata, Macq. S. a B. i. 94). 

 Spania Fallenii, C. 1203^. 2.— Ent. Mag. i. 162. 



Notwithstanding the different form of the antennae I am led 

 to consider this as the female of Sp. nigra, which occurs more 

 frequently in the same marshes in the month of June. The 

 proboscis is longer in the females and the palpi not exactly 

 linear. I have no longer any doubt as to the place of this ge- 

 nus among the Leptidce. 

 Medeterus ruficornis, C. 1256. 5. App. 279. 



M. obscure aeneus, fronte thoraceque olivaceis ; antennis brevis- 

 simis rufis margine apicis fusco ; palpis pedibusque pallidis, 

 tarsis fuscis ; nervo transverso ordinario ab alae margine remoto, 

 m.f. ; hypopygio recondite, m. Long. I4 lin. 

 Tarbert, July. 

 Dolichopus sabinus, C. 1258. 9^. App. 279. 



D. ciliis genarum albidis ; viridi-seneus antennis basi subtus rufis ; 

 pedibus pallidis, tarsis nigris basi pallidis ; alarum costa ex- 

 teriore infuscata, m.f. ; tibiis posticis basi variolosis, femoribus 

 imberbibus, lamellis albidis, m. Long. 2 lin. 

 Killarney and Tarbert. 

 Dolichopus signifer, C. 1258. 9^ App. 279. 



D. ciliis genarum albis ; viridi-seneus femoribus apice tibiisque 

 pallidis posticis apice nigris; alarum apice nigricante ; m.f. 

 femoribus posticis subtus fusco- ciliatis, lamellis albidis, m. 

 Long. 2 lin. 

 On a sandy islet in Roundstone Bay. 

 Platypeza infumata, C. 1248. 14. 



P. caesia halteribus pedibusque fuscis, tarsis basi pallidis ; thoracis 

 macula tridentata atra ; abdominis fasciis atris, duabus anterio- 

 ribus confluentibus,/. Long. -I lin.
