" Paisley pug." He said that when he exhibited these insects 

 on a former occasion (Abst. Proc, 1890, p. 60) he was then 

 disposed to consider them referable to E. satyrata, whilst Mr. 

 Tutt and others were of opinion that they were dark examples 

 of £". virgaureata. He had recently received pupae of the insect 

 in question, and having compared them with pupae of E. casti- 

 gata he had now come to the conclusion that the so-called 

 "Paisley pug" was a melanic form of that species. If the 

 imagines were examined in different positions the characteristic 

 linear markings of E. castigata could be clearly traced. 

 Referring to E, virgaureata, Mr. Tugwell said that he had 

 ascertained from local collectors that that species did not 

 occur in the Paisley district, and that golden-rod, the food 

 plant, which was extremely rare in the neighbourhood, did 

 not exist at all in the particular locality where the dark 

 Eupithecia were taken. Mr. Barrett thought that absence of 

 golden-rod had very little bearing on the question, as the 

 larva of E. virgaureata would feed on several other plants ; 

 from an examination of Mr, Tugwell's melanic specimens, 

 however, he was inclined to consider them referable to E. 

 castigata. At Cannock Chase he had found E. castigata in 

 profusion on the boughs of oak trees, and a large proportion 

 of the specimens were nearly as dark as the examples under 

 discussion, whilst others gradated between that form and 

 the type.
