furnislicd along their inner surfaces in both sexes with soft black hairs of moderate 

 lengths, and are armed on their outer sides and ends with long black spines ; the 

 inner extremities of the tibia?, and under-surfaces of tarsi, are clothed like the other 

 tai-si with golden hairs. 



Tliis interesting fly seems to bo widely distributed on tlio British 

 coast, but is of rare occurrence. It lives jimong the remains of sea 

 weed and other marine rejectamenta above high water mark. The 

 first specimens I saw were kindly sent to me for identification by 

 Mr. W. H. Harris of Cardiff,* who captured them on the Welsh 

 coast, in September, 18S4. He found another pair near Cardiff this 

 last summer (1S85), and also a single specimen at Ilfracombe in July. 

 I ca])tured a pair myself (cJ & ? ) at Douglas, Isle of Man, on June 

 20th, 1885, in company with numerous specimens of Fucelhafucorum, 

 Scatina liforea, and other marine flies ; but though I searched carefully 

 on many subsequent days, I never met with another individual.
