48 THE ENTOMOLOGIST. 



it is to be met with abundantly, often in such numbers as to 

 become a pest in the sweep-net among reeds and osiers. It is 

 confined here to June 5th-20th, and a diligent search at its 

 headquarters on May 22nd and July 4th revealed none ; Wicken 

 Fen in Cambs, Surlingham and Rockland Broads in Norfolk, 

 very rare at Brockenhurst, but always to be found in North-west 

 Suffolk at Barton Mills, Brandon, and Tuddenham Fen. M. 

 rustica is more widely distributed, though rarer in the eastern 

 counties. I have only a couple of specimens, taken at Woolpit, 

 in Suffolk, by Rasor in July, 1904, and sent by Rev. E. N. Bloom- 

 field, probably from the Hastings district. M. blanda is very 

 rare here ; I swept a single female from oak in a lane at Wher- 

 stead, near Ipswich, on June 16th, 1904. M. annulata (neglecta, 

 Cam.), on the contrary, is common in Suffolk at Tim worth (Col. 

 Nurse), Needham Market (Platten), Bentley, Barton Mills, Bram- 

 ford, and Moulton ; I have also seen it in the New Forest and 

 Isle of Wight. Both M. albicincta and M. ribis seem rare ; the 

 former has been swept in marshes at Brandon and Rockland 

 Broad in early June, the latter at Burwell Fen, and once — only 

 once in twelve years' collecting there— at Belstead, in Suffolk, at 

 the end of May, 1904. Why so few Allantus species have turned 

 up, I do not know, unless they be rare; at least one, A. rossii, 

 seems doubtfully British, and I have never seen half the remain- 

 ing nine. A. scrophularim is a remarkably handsome, vespiform 

 species, always to be met with along with Vespa germanica at 

 Scrophularia nodosa throughout Suffolk. Sich has given it me 

 from Malvern in Worcester ; it is not an early species, but is on 

 the wing from the middle of June to that of August. Of A. 

 marginellus and A. amosmis, I possess single examples only, pre- 

 sumably captured about Ipswich in 1894, but if such were the 

 case, it is strange they never put in a second appearance. 

 A. arcuatus can be accused of no such retiring habits, for it is 

 ubiquitous from June 5th to September upon all sorts of umbel- 

 liferous flowers, from which I have frequently seen it chase flies, 

 though I was never so fortunate as to witness a capture ; but 

 Elliott has given me a female, which he took at Banchory in the 

 Highlands, in the act of masticating a female Empis pennipes, 

 Linn., proving its carnivorous propensities. I have it from 

 Clare Island, Co. Mayo ; Glengarriff (Andrews), Skene and 

 Ballater (Elliott), Isle of Wight, Hants, Wilts, Lines, Suffolk, 

 and Northants. 



Next we come to the typical and handsome genus Tenthredo, all 

 of which have terrible jaws, and must on no account be boxed with 

 other insects. Only T. mandibularis of the thirteen indigenous 

 species is unknown to me. T. maculata is one of our largest and 

 most striking sawflies, and is beaten from bushes in the middle of 

 sparse woods in the middle of June ; I took it this year flying 

 slowly along in the Willingham Woods, near Louth, in Lincoln-
