136 Mr. H. T, Stainton's Remarks on Extracts 



which it also resembles in size ; but on the anterior wings of 

 cursor'iella the two spots lie more obliquely to one another, and 

 its inner margin at the base is yellow. The likewise very similar 

 assimilella wants the inner marginal streak, which also has a 

 yellowish spot on the disk. 



" At Frankfort-on-the-Main (V. Heyden) and at Vienna in 

 the Prater, on fences in June. (Mann.)" 



I should have said undoubtedly this was the suhhimaculella of 

 Haworth ; but that Zeller says " cilia clear grey." The yellow 

 base (which is so frequently continued on the inner margin), the 

 yellow spots placed obliquely to one another, are here fully de- 

 scribed ; but Zeller says cilia clear grey (hell grau). Now in 

 our species they are the same colour as the spots, yellowish. 



Zeller gives, as a doubtful synonyme, trimaculella, Haworth, 

 Staph. Now in the first place the trimaculella of Stephens is not 

 the trimaculella of Haworth : it is quite true that Mr. Stephens 

 has copied Haworth's description, but he has added to it four 

 Tvords, which will not apply to Haworth's species. At the same 

 time the remainder of Haworth's description will hardly apply to 

 any other species ; so that the description in the Illustrations being 

 a patchwork concern, half applying to one species and half to 

 another, is good for nothing. The trimaculella of Haworth is the 

 rufella of Zeller ; and Haworth's name, having priority, must 

 stand. 



Haworth says (Lepidop. Brit. 583, 82) : 



*' Alis atris, stria lata basi, maculisque duabus posticis flavi- 

 cantibus. 



" Habitat forte in populo. Imago i. Jul. Populi truncis, at raris- 

 sime. Exemplarium unicum quod cepi sedentem solum vidi. 



" Expansio alarum 2| lin. 



" Descriptio : praecedentibus minor. Alae anticse atrae, stria 

 latissima emarginat^, a basi fere ad medium lutescente, maculisque 

 duabus posticis oppositis marginalibus fere confluentibus flave- 

 scentibus." 



Stephens says (Illustr. 4, 267) : 



" Alis anticis atris, stria latd basi, maculisque duabus posticis 

 flavicantibus. 



" Anterior wings deep black, with a very broad emarginated 

 yellowish streak, reaching from the base to near the middle of 

 THE INNER MARGIN, and two spots towards the apex, placed one 

 on the costa, the other towards the hinder angle and sometimes 

 nearly confluent: posterior wings dusky black." 



" Rare : found at the beginning of July in the vicinity of Lon- 

 don, in gardens."
