TSpeorus st/lvicola, Ed. Pict. {Baetis sylvicola, Ed. Pict. ; Epeorus ffeminus, 

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

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



Rhithrogena aurantiaca, Burm. — A ^ imago at Ponte de Morcellos ; other 

 species of this genus no doubt occur in the Estrella, but none of the most likely 

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



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

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



JEcdyiirus iluminum, Pict. — A ^ sub-imago from the stream flowing south of 

 Monchique was captured on May 19th. 



This list is based almost entirely upon specimens now in tbe 

 collection of Mr. E. McLachlan.

OCCURRENCE OF BOTH STEGANOPTYCRA PYGM^ANA, HB., AND 

 S. ABIEOANA, DUP., IN ENGLAND, AND THE LATTER SPECIES 

 IDENTIFIED AS THE TORTRIX SUBSEQUANA OF UAWORTH. 



BY WILLIAM WAEREN, F.E.S. 



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

 Asthenia fyifmcsana^ as follows : — 



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

 with silvery, enclosing three longitudinal Mack 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 

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

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



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

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

 description in the Manual to be pygmceana, " except that the ocellus had 

 no black lines." On comparing one of these insects with those 

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

 species: Mr. Boden's being abiegana, Du\). ; the others, pi/ ffmcsana,}lh. 



Of pi/ffmceana a very accurate description is to be found in 

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

 Forst-Insekten, p. 22G, who also figures the insect in all its stages, 

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

 by Herrich-Schaffer, iv, p. 281, who also figures abiegana, fig. 128. 



I give here a short description of each : — 

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

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

 basal patcli with its outer edge consisting of i\oo distinct curves, which at their
