Trent by the late John Sang, at York by the late W. Prest, 

 Mr. Porritt recognised it as an insect he had taken at Edlington 

 Wood near Doncaster, and I discovered it in great abundance 

 in Hezleden Dene near Hartlepool, and the following year at 

 Edder Acres, a wood near Thornley Station, and closely con- 

 nected with the upper end of Castle Eden Dene. In the dene 

 itself Mr. E. R. Bankes found it "plentiful on tree trunks, and 

 very conspicuous." Shortly afterwards it was found to be the 

 same insect that had been taken by Mr. Dale and named 

 Ulmella so long before. The new name, Conspicualis, ought to 

 have been dropped, but both names had been placed on our 

 lists, and still appear on some. This long explanation will 

 prevent future confusion. 



Eor these counties I have no records except from the woods 

 and denes around Hartlepool, but the insect is so plentiful in 

 these that it must occur elsewhere, and if collectors will 

 examine the tree trunks in rather open woods in the latter 

 half of July and the beginning of August I will be surprised 

 if they do not turn up Ulmella. 



Mr. Meyrick merges Ulmella with Amligualis, but those 

 who have given special study to the group have no hesitation 

 in pronouncing them distinct species.

This is another insect introduced since the publication of 

 Stainton's Manual. It was first announced in the Entomologist's 

 Monthly Magazine, vol. iii., p. 1, and in the Entomologist's 

 Annual for 1867, p. 140. This also has been "lumped" with 

 Ambigualis, but it appears to have strong claims to distinctness. 

 It is larger and more robust looking, with broader forewings 

 and more rounded costa. I never saw it alive myself, but those 

 who have tell me it is noticeably distinct as it sits on the trees. 

 There is also in Basistrigalis a thickening of the first line at
