A SYNOPSIS OF BKITISH PROCTOTRYPIDiE (oXYURa). 133 



Though only recorded from Sweden, this is not an uncommon 

 species with us, and seems confined to the autumn. It ranges 

 from August 9th, when I took it in the West Leake Woods near 

 Nottingham, in 1914, to October 8th, when it occurred under 

 some sacking lying on the ground in Dodnash Wood, in Suffolk • 

 it has occurred by sweeping at Blythburgh Wood, and I have 

 noticed it on the Lowestoft cliffs flying slowly and hovering over 

 the sand, about half-way up their face, on an oppressively hot 

 morning with slight westerly breeze. Foxhall (Tomlin) : Tostock 

 near Bury St. Edmunds (Tuck) ; Felden, in Herts (Piffard). 



10. Proctotrypes elongatus, Hal. 



Proctotmpes elongatus, Hal., I.e., p. 11, ? . Serphus elonaatus 

 Andre, Z c, p. 302, ? . 



Somewhat rare in northern Ireland, " in litoribus " (Haliday), 

 which Kieffer considers to mean " rivage de la mer.' It has not 

 been anywhere discovered since first described in 1839, and is 

 said to be similar in its abdominal and terebral structure to 

 Paracodrus apterogynus ; nor is the male yet known. 



11. Proctotrypes calcar, Hal. 



Proctotrupes calcar, Hal., I.e., p. 12, $ 2 ; Toll., I.e., p. 28, 

 pi. xix, fig. 10, ? . P. calcaratus, Thorns., I.e., p. 419, 3 . Serphus 

 calcar, Andre, I.e., p. 306, $ 2 . 



The large radial cell, combined with elongate pale legs and 

 evenly sculptured metathorax, render this a very distinct species. 



A common insect in woods from spring to autumn, extending 

 throughout Europe, from Sweden to Spain and Algeria. Haliday 

 considered it very common in woods and among grass on coast 

 sandhills, and recorded it from England. For its most interesting 

 parasitism upon the centipede, 'Lithe-bins foi -ficatus, cf. Edward 

 Newman's paper in ' The Entomologist,' iii, 1867, p. 342, " A 

 Proctotrypes Parasitic on a Myriapod " ; I know of no subsequent 

 breeding. One of our commonest species, at least in the east of 

 England, and ranging from early May to September 8th, most 

 abundant in June. About half my localities are on the coast, 

 but it also frequently occurs inland in marshes, and sometimes 

 on lime-tree honey-dew, at Barton Mills. Mildenhall, Monks 

 Soham, and Walberswick in Suffolk ; Bury St. Edmunds (Tuck) ; 

 Mablethorp, in Lines, and Newstead, in Notts (Morley) ; Clacton- 

 on-Sea (Newbury) ; Felden, in Herts, several (Piffard) ; Beigate, 

 in Surrey (W. Saunders) ; Lyme Begis, in Dorset (Chitty) ; New 

 Forest (Lyle) ; Olveston, in Gloucester (Charbonnier) ; Arnold. 

 Edwinstow, in Sherwood Forest and Aspley Woods in June, 

 Thorney in August ; and Epperstone Park during September, in 

 Notts (Carr) ; Killarney, in S.W. Ireland.
