26 THE MAYFLY 



black-headed gulls hopping about amongst the 

 trees from twig to twig, with all the agility of 

 the little sparrow, in their eagerness to take toll 

 of these tit-bits of the insect world. 



Mr. Eaton writes of Ephemera lineata : 



" Anterior segments greenish-grey, modified 

 with bistre-brown ; hinder segments more of 

 a yellowish-brown. The dorsal markings of 

 the segment consist of longitudinal, curved, or 

 slightly sinuous black streaks tapering at both 

 ends viz. in the anterior segments, two such 

 streaks, which are long, on each side of the 

 middle of the back ; in the hinder segment, be- 

 tween these two pairs of streaks, two short black 

 lines from the base of the segments. Ventral 

 markings, a pair of longitudinal black lines. 



" I have met with this species in England 

 only in the neighbourhood of Reading in Berks. " 



Personally, I have never found this species, 

 but I give the description in case other angler- 

 entomologists should be more fortunate. The 

 figure given in the " Dry-Fly Man's Handbook," 

 showing these markings, is reproduced here by 

 the kind permission of Mr. Hal ford. Ephemera 

 vulgata and Ephemera danica were drawn from 

 specimens in my possession, and the single seg- 

 ment showing the markings of Ephemera lineata 

 is reproduced from a drawing by Mr. Eaton 

 in the " Transactions of the Entomological 

 Society." (Fig. 3.) 



It should be noted that Mr. Eaton's descrip- 

 tions given above have reference to the imagines 

 only.
