JEchmia Stanneella, F-v-R. (p. 248). " Rather smaller than M. metallicella, of a 

 pale silvery gray, inclining to a yellowish colour, veiy glossy : the duller posterior 

 wings have besides a very faint violet tint. Before the anal angle of the anterior 

 wings is a whitish spot, but it is so lost in the pale ground colour that it only becomes 

 perceptible when the sun shines on it." A single specimen taken by Mr. Douglas, 

 in company with sericiella, May 4, 1849, at Coomb Wood. 



Myelois Artemisiella, Steph. MSS. Not closely allied to any species I am ac- 

 quainted with. Exp. alar. 7 — 9 lines. Head, thorax and anterior wings pale dirty 

 ochreous, the latter with a paler sinuous hinder fascia, followed by a dark cloud on 

 the costa, and preceded by a similar dark cloud a little removed from the costa, which 

 is continued as a dark streak along the middle of the wing to the base : near the 

 costa, a little before the hinder fascia, is a black spot ; and a row of dark spots 

 on the hinder margin : posterior wings pale cinereous. This species has been bred 

 by Mr. Simmons from larvae, feeding within the stems of Artemisia campestris. 



Bucculatrix cristatella, F-v-R. A single specimen, the locality of which is un- 

 known, is in Mr. Douglas's collection. A note of the distinctive characters of this 

 species appears in the Society's Transactions, vol. v. p. 128. 



Gracilaria P Ocnerostomella. Exp. alar. 4 — 5 lines. Last joint of palpi stout 

 and not pointed: head, thorax, antennas and anterior wings concolorous, gray, some- 

 times with a slight ochreous tinge : the wings are entirely destitute of markings, 

 which readily distinguishes it from any known Gracilariae, whilst the longer palpi 

 immediately separate it from Ocnerostoma ; and the smooth head, long posterior legs, 

 and long cilia at the anal angle of the anterior wings, at once remove it from Argy- 

 resthia. I exhibited an imperfect specimen of this species to the Society in Novem- 

 ber last, as Argyresthia Amiantella ?, imagining the hairs on the crown of the head 

 to have been rubbed off : the sight of several fine specimens, taken by Mr. Douglas, 

 at Mickleham, in June, 1848, has convinced me that it is not Amiantella, and not 

 even an Argyresthia ; but from the thickness of the last joint of the palpi it ill accords 

 with any known Gracilaria. 



Crambus uliginosellus, Z. in litt. Distinguished from C. pascuellus, with which it 

 has hitherto been confounded, by its shorter and less pointed anterior wings, the white 

 streak on which is less gradually pointed ; the posterior wings are whiter, and the 

 palpi and thorax are likewise whiter. One specimen taken at Lewisham, at light, 

 June 21st, 1848. 



Mr. Westwood exhibited a specimen of Ophion undulatum, taken in this country. 



April 1, 1850.
