Aphalara pilosa, Oshn. 



Scott gave a descriptioti of Aphalara artemisice, Forst., in Ent. 

 Mo. Mag., xiii, p. 67, and subsequently, on page 282, he introduced 

 the species as British on material taken by J. C. Dale on July 27th, 

 1843, and he expressed his opinion that these specimens, the locality 

 for which he did not mention, were probably found on Artemisia 

 maritima. Naturally I concluded that the Aphalara which I found 

 on Artemisia maritima at Weybourne, Norfolk, belonged to the same 

 species as those mentioned by Scott, particularly as my specimens 

 agreed very well with his description of A. artemisice, Forst., so far 

 as it goes. My description of Aphalara artemisice (Hem. Horn. Brit. 

 Isl , p. 232) was made from Weybourne specimens, and Professor 

 Oshanin recognised in it his Aphalara pilosa. I have not been able 

 to trace the specimens recorded by Scott, but Professor Poulton has 

 kindly allowed me to examine specimens from the Dale Collection, 

 taken in the Isle of Portland in 1877, which appear to be the true 

 A. artemisice, Forst. The two species may be readily distinguished as 

 follows : — 



Elytra naked ; cell 4 subequal in length to the width of its distal edge... 



artemishe Forst. 

 Elytra with scattered pale hairs ; cell 4 nearly twice as long as the width of its 

 distal edge pilosa, Osh. 



A. artemisice, Forst., lives on Artemisia absinthium and A. cam- 

 pestris ; Dale's Portland specimens could not have come from the 

 latter, but as Mansell-Pleydell (Flora of Dorset, ed. ii, 1895, p. 155) 

 says that the former occurs by the roadside on ascending to the 

 Verne, and among the quarries at Portland, there seems a reasonable 

 probability that they came from that plant. 



Trioza silacea, Meyer-Dur. 



munda, Flor (nee Forst.). 

 T do not know this as a British species, though " Britannia " is 

 given for it by Oshanin. Flor, writing of silacea, Meyer-Dur, under 

 the impression that it was the same as munda, Forst., gives amongst 

 other localities England (Walker) and Ireland (Haliday), but it seems 

 likely that he copied these particulars from Forster's account of his 

 munda. T. silacea was found by Flor abundantly on nettles in July 

 and August ; it may be distinguished from our common nettle- feeding 

 species by the forceps of the male, which are gradually narrowed and 

 little more than twice as high as their width at the base.
