Epeorus syloicola, Ed. Pict. {Ba'etis sylvicola, Ed. Pict. ; Epeorus ffenilnu-t, 

 of Trans. Linn. Soc. (2) Zool., iii, 238). — In flight, at 10.30 a.m. on June 7th, ovei* 

 a stream in the Estrella, south of Sabugueiro, at an altitude of 4200 feet. 



Rhithrogeiia aurantiaca, Burm. — A ? imago at Ponte de Morcellos ; other 

 species of this genus no doubt occur in the Esti-ella, but none of the most likelj 

 streams were visited in the evening, being far from Cea. 



Heptagenia sulphurea, Mull. — Ponte de Morcellos ; the specimens have been 

 noted as a variation in op. cit., p. 270. 



Ecdyurus flutninum, Pict. — A 9 sub-imago from the stream flowing south of 

 Monchique was captured on May 19th. 



This list is based almost entirely upon specimens now in the 

 collection of Mr. E. McLachlan.

OCCUEEENCE OF BOTH STEGANOPTYCHA PYGMJEANA, HB., AND 

 S. ABIEGANA, DUP., IN EN&LAND, AND THE LATTEE SPECIES 

 IDENTIFIED AS THE TOETRIX SUBSEQUANA OF UAWOETH. 



BY WILLIAM WAEEEN, F.E.S. 



In vol. ii, p. 207, of the Manual, Mr. Stainton describes an insect, 

 Asthenia pygmcsana, as follows : — 



" Fore-wings glossy, pale grey, with reddish-brown markings ; ocellus edged 

 with silvery, enclosing three longitudinal black lines ; hind-wings with the base 

 pearly-white. Two specimens formerly in Haworth's collection ; locality unknown." 



I am not aware that any more specimens of the insect were taken j[ 

 until a few years since, when Mr. Boden came across them somewhere 

 in the London district ; of these iiisects I possess a pair. 



A fortnight or so ago, a friend showed me on his setting-board 

 three Tortrices which he had lately taken, and made out from the 

 description in the Manual to he pijgmceana," except that the ocellus had 

 no hlack lines.'''' On comparing one of these insects with those I' 

 captured by Mr. Boden, it was at once evident they were distinct 

 species : Mr. Bodeu's being ahiegana, Dup. ; the oi\iev^,pygm(jBana, Hb. 



Of pygmceana a very accurate description is to be found in 

 Snellen's De Ylinders van Nederland, p. 342, and in liatzeburg's 

 Eorst-Insekten, p. 226, who also figures the insect in all its stages, 

 T. 12, fig. 9. Both species are described in Ileinemann, p. 217, and 

 by Herrich-Schaffei*, iv, p. 281, who also figures ahiegana, fig. 128. 



I give here a short description of each : — 



Tygmaana, Hb. — Fore-wings greyish-brown, with a few rust-coloured scales 

 intermixed, especially towards the hind-margin. Markings dark blackish-brown ; 

 basal patch with its outer edge consisting of two distinct curves, which at their
