284 THE ENTOMOLOGIST 



Southampton (Gorham). T. equiseti is hardly rarer in Suffolk 

 and the New Forest ; Elliott found it at Clunie, in Scotland, on 

 August 16th, 1907. But I do not know the other two species 

 of the genus. 



The Dolerides mark the beginning of the end of these 

 remarks, for after them are only the Tenthredinides, which I 

 shall reserve for a final note. Two of our three Loderi are 

 known to me : L. palmatiis by a pair captured at Tostock, in 

 Suffolk, by Tuck in June, 1899, and a doubtful male from Bram- 

 ford ; L. vestigialis is not uncommon in marshes at Foxhall, 

 Barton Mills, and Farnham, in Suffolk, from the end of May to 

 middle of June. The genus Dolerus is one of the best known 

 and most difficult of elucidation ; some of its species are 

 ubiquitous and others extremely rare. I possess but a single 

 female of Z). triplicatus, captured by the late A. J. Chitty at 

 Colchester in May, 1907; but D. madidus is not infrequent from 

 the end of April to beginning of July in marshes at Ipswich, 

 Tostock, Matley Bog, and Burley, in Hants, being sometimes 

 swept at dusk. My single D. ferrugatus was found at Gosfield, 

 in Essex, early in June, 1903, by Alfred Beaumont. D.jJratensis 

 is extremely abundant everywhere ; I have found it at all times 

 from April 1st to August 29th about Dover, the Norfolk Broads, 

 and all over Suffolk. On the wing it has a peculiarly straight 

 and sustained flight, accompanied by a distinct humming noise, 

 buzzing along like a Zygaenid moth. My only D. cericeps was 

 swept at Hursthill, or Queen's Bower, in the New Forest, on 

 July 11th, 1909 ; but D. palustris is much commoner, and 

 turned up at Rookley Wilderness, in the Isle of Wight ; at 

 Dunwich, Bentley, Bramford, and Stanstead, in Suffolk; and 

 Gorham found it in Herefordshire. Many of the black-bodied 

 species are abundant, though difficult to name. Of these, 

 1). gonager is among the commonest, and usually turns up by 

 sweeping reeds ; I have it from Norfolk, Suffolk, Hants, and 

 Kent, the dates of capture varying from May 9th to July 14th. 

 D. liogaster seems, on the contrary, to be very rare, since my 

 single specimen turned up on reeds at Tiieberton, in Suffolk, on 

 July 10th, 1900; but the handsome D. hamatodes is by no 

 means infrequent in my paddock and even on the windows here. 

 I have received it from Doncaster, and used to find it on aquatic 

 plants about Ipswich at Foxhall, and on the banks of the Gipping 

 from April 19th to June 5th. The var. ravus of D. sanguini- 

 collis is common in Suffolk at Brandon, Lavenham, and Stoke- 

 by-Clare at the end of May ; I have also taken it at Burley, in 

 the New Forest, early in July. D. niger is a large and fine 

 species, unknown in Suffolk, though it has occurred to me at 

 Setley and Rhinefields, in the New Forest, on July 12th, and at 

 Helpston Heath, near Peterborough, on June 13th. D. anthra- 

 cinus is the earliest of all species in my experience, since I have
