FIELD NOTES ON BRITISH SAWFLIES. 47 



have founds, pictus (Morice forget to " masculate " the species 

 of this genus) sparingly in the marshes of the Little Ouse at 

 Brandon ; it has occurred to rue at the Haven Street Woods in 

 the Isle of Wight, and Miss Chawner takes it in the New Forest, 

 always in June, I believe. R. punctulatus occurs with the follow- 

 ing in woods, and is very liable to be mixed with it, though dis- 

 tinctly rarer ; I have it from Norfolk, Suffolk, and the Isle of 

 Wight. R. viridis, a beautiful and very pugnacious species 

 (with which bottle no other insect!), is abundant everywhere 

 from May to September; Banchory in the Highlands (Elliott), 

 Ardross in Co. Ross (Gorham), Tuddenham Fen (Chitty), Suffolk, 

 New Forest, Isle of Wight, &c. It is especially common on the 

 flowers of Heracleum sphondylium. R. fulvipes is confined to 

 May, in my experience ; it occurs throughout Suffolk, and is 

 usually taken on bramble-leaves. R. aucuparice is even earlier 

 in its appearance, about April 28th ; it is commoner than the 

 last, and only extends to early June. Usually taken by sweep- 

 ing damp hedge-bottoms ; Burwell Fen in Cambs, and Skegness 

 in Lines (Elliott), common all over Suffolk. Our single species 

 of Perineura must be widely distributed, if the female in Capron's 

 collection was from his usual locality, Shere in Surrey, for males 

 are recorded from Cadder in Lanark, but these are the only 

 known indigenous specimens ; it is said to occur in May, pro- 

 bably among ferns (besides E. M. M. 1910, p. 236, cf. I. c. 1911, 

 p. 103). Pachyprotasis rapes is one of the commonest British 

 insects in June, continuing to appear sparingly through July 

 and August, even to September in Scotland. All my specimens 

 are from woods, usually by sweeping; Felden in Herts (Piffard), 

 New Forest (Miss Chawner), Banchory (Elliott) ; abundant in 

 Lincolnshire and Suffolk. P. antennata has extremely rarely 

 occurred to me, but is, I believe, common enough about Lynd- 

 hurst ; Halbert took it at Belclare, on the Mayo coast, in July, 

 1910, and I once found it atHelpston Heath, near Peterborough, 

 in June. 



The deep red and black, often with conspicuous white mark- 

 ings, render Macrophya a striking genus, while the rarity of 

 most of its species adds to its interest. Morice says all our 

 species are " mostly fairly common, at least in the southern 

 counties," but I have not found them so. Excepting the two 

 doubtfully British M. albipuncta and M. diversipes, I have, never- 

 theless, obtained all our species but M. rufipes, known from 

 Swanage, Worthing, Effingham, and the New Forest. My M. 

 punctumalbum were taken at the last locality by Miss Chawner ; 

 it is said to frequent privet during May and June. M. duo- 

 decimpunctata seems much commoner in the fens and broads of 

 the eastern counties than elsewhere ; Morice has taken it " occa- 

 sionally," and suggests an attachment to alder, which is probably 

 correct, for in East Anglian marshes, where that tree abounds,
