FIELD NOTES ON BRITISH SAWFLIES. 191 



at Brandon at the end of August, 1905, where also, as well as at 

 Winterton in Norfolk, I have swept Eriocampoides annulipes in 

 June. E. variipes, Klug, is not uncommon in June and July at 

 Walberswick, and in the Bentley Woods. The two interesting 

 species, E. cethiops and E. limacina, are not at all common with 

 us ; the former was, however, not rare on May 31st, 1900, 

 examining the leaves of Rosa canina in the Bawdsey Marshes, 

 near Felixstowe, and I noticed several on those of cultivated 

 roses in the garden of our lodgings in Wicken early in June, 1902. 

 Of the latter, I have given some account in the first volume of 

 ' The Countryside ' from a number of cherry-tree leaves sent me, 

 from which this " slugworm " had quite devoured the epidermis ; 

 it rarely turns up in the Suffolk Bentley Woods and the Kent 

 Blean Woods, though essentially a garden insect. Hoplocampa 

 pectoralis and H. rutilicornis must, I think, be rare, since I have 

 found but one of each, the former in a very marshy place among 

 osiers at Barton Mills on June 12th, 1889, and the latter (female) 

 on some bushes in Dodnash Woods, near Ipswich, on April 27th, 

 1897. But both H. cratcEgi and H./crru^ri/iea are abundant in 

 hedges throughout the spring, and in June, 1899, I bred one of 

 the former, referred by Mr. Morice to the doubtfully distinct form 

 H. aZpi?ia, Thoms., which I am strongly of the opinion (though 

 my notes fail me) emerged from a gall of Cynips kollari, where it 

 had perhaps hybernated. 



Several of the Blennocampides are among our commonest 

 sawflies, and all have a particularly svelte appearance, claiming 

 particular attention in the net. Mesoneura opaca {Dineura 

 verna, olim) appears pretty regularly in the Bentley Woods 

 about May 20th, but I have not seen Phymatoceros aterrima there 

 since 1894 ; and both sexes of Pareophora nigripes are rare at 

 the same time of year at Foxhall and Lavenham, in Suffolk. 

 All my Periclista melanocephala were taken at Bentley or Assing- 

 ton in woods in May, except one pair, which the late Mr. J. W'. 

 Cross sent me during the same month from Brockenhurst, in 

 the New Forest, where, in Matley Bog, I found Ardis sulcata not 

 rarely in the middle of last June. Tomostethus fidiginosus is 

 common throughout Suffolk and in the Isle of Wight from the 

 end of May to that of August, usually by sweeping low herbage, 

 and both T. duhius and 2\ luteiventris are among the commonest 

 British species, being constantly swept from low herbage in damp 

 situations ; the former I have from Norfolk, Suffolk, and Cam- 

 bridgeshire, while its black-thoraced variety nigrans, Knw., was 

 very abundant in Matley Bog, among alders, last June, and with 

 it occurred the latter species in the greatest profusion, as, 

 indeed, it also does in Suffolk, Norfolk, and the Isle of Wight. 

 Of the genus Blennocampa, as now restricted to six species, none 

 can be called really common, though B. pusilla and B. alternipes 

 are perhaps most frequently met with, the former in May and
