ON THE PROCTOTRYPID GENUS GONATOPUS, LJUNCH. 225 



-two or three specimens in August, 1908, at the roots of rough 

 grass and beneath stones on the coast sand-hills at Lowestoft ; 

 and possess two more found, presumably at Felden, in Herts, by 

 Albert Piffard about 1900. 



3. Gonatopus pedestris, Dalm. 



Sv, Ak. Handl. 1818, p, 86 ; Nees, Mon. ii, 1834, escll. synon. 

 'et c? ; Thorns. Ofv. 1860, p. 180; Kirchner, Lotos, vi, 1856, p. 233, 

 fig. 5; Mik. Wien. Ent. Zeit. i, 1882, p. 215, pi. iii, figs. 4-10; 

 Kieff. Hym. d'Europ. 1904, p. 96. G. Ljimchii, Westw. Loud. 

 Mag. vi, 1833, p. 496 ; Chitty, Ent. Eec. 1907, p. 80. 



Till the end of the last century it was customary to consider 

 all British Gonatopi as referable to G. pedestris, bo nothing can 

 be ascertained respecting its true distribution with us. Chitty 

 •could not distinguish Westwood's type — taken on Wimbledon 

 Common — from true G. pedestris, and thought them synonymous. 



4. Gonatopus oratorius, Westw. 



Loudon's Mag. Nat. Hist, vi, 1833, p. 496 ; Chitty, Entom. 

 Eec. six, 1907, p. 79. 



Sunk as a synonym of G. pedestris by Walker, and reinstated 

 by Cbitty on examining the Oxford type. The latter regarded it 

 as distinct from any of Kieffer's species. It was found on Eipley 

 Common, and " it ought to be possible still to take this insect 

 on the Surrey commons." 



5. Gonatopus distinguendus, Kieff. 



Andre, Spp. Hym. d'Europ. 1904, p. 116. 



Described from a British female taken in a sandy place. The 

 late Alfred Beaumont subsequently found it at Kilmore, in Ireland, 

 on August 11th and 15th, 1898. I possess one of those taken on 

 the 11th ; it is labelled " sand-hills by sweeping." 



6. Marshalli, Kieff. 



Gonatopus lunatus, Nees, Mon. ii, 1834, p. 383 {nee Klug) ; 

 G. Marshalli, Kieff. Hym. d'Eur. 1904, p. 121. 



Kieffer gives the above synonymy, but it is difficult to under- 

 stand how Nees' species could differ from that of Klug, when the 

 former distinctly and only says of it : " Habitat Beroliui (Klug). 

 Feminam vidi, a cl. Klugio ad me missam," without claiming to 

 have taken it himself. Also Kieffer does not record it from 

 Germany; simply, "Angleterre: He de Purbeck, Swansea," which 

 Chitty considers an error for Swanage, and doubtless correctly, 

 for at lib. cit. p. 510 we find nothing but "Patrie : He de Purbeck 

 et ile de Corse. (D'apres les types de la collection de Marshall.)" 

 I have taken this species running in a gravel pit at Lymington 

 on August loth, 1901.
