226 THE ENTOMOLOGIST. 



7. Gonatopiis hicolor, Curt. 



Dryinus j^edestris, Hal. Entom. Mag. ii, 1835, p. 221 (?); 

 Dryinus bicolor, Curtis, Brit. Entom. fol. 206-7, 1828 ; Gonatopns 

 nigriventris, Nees, Mon. ii, 1834, jd. 386 ; Dicondylus pedestris, 

 Walk. Entom. Mag. iv, 1837, p. 412: Entom. vii, 1874, p. 27, 

 fig. ; G. hicolor, Kieff. Hym. d'Europ. 1904, p. 108 {ncc Ashm.). 



Germany, Corsica, and Britain, whence Chitty records it in 

 the counties of London, Kent, Herts, and Haddington. Probably 

 not rare, though formerly merged in error with G. pedestris by 

 Walker. The synonymy given in 'Genera Insectorum,' liv, 1907, 

 is erroneous. I took the Herts specimen beneath Genista anglica 

 on a common just above Boxmoor station on August 9th, 1903. 



8. Gonatopns distinctiis, Kiefi:'. 



Andre, Spp. Hym. d"Europ. 1904, p. 509. 



This species was thought sufficiently distinct to merit a name 

 by its author, who picked it out of the series, considered by the 

 latter to be identical, in Marshall's British collection. Chitty 

 knew the species from Surrey' in June and July, and from Corn- 

 wall. I have recorded it (Proc E. Irish Acad, xxxi, 1911, No. 24, 

 p. 17) from Clare Island during June, 1911 ; and Donisthorpe 

 tells us in 1915 that it consorts with the ants Myrmica rubra 

 var. IcEvinodis and Formica fusca var. gleharia, Nyl. It has twice 

 occurred to me in the New Forest by sweeping ; once in a 

 gravel-pit at Brockenhurst on Julv 7th, 1909, and once in 

 Matley Bog on June 9th, 1911. 



To these I can now add : 



9. Gonatopns pilosus, Thoms. 



G. formicarius var. 7, Nees. Mon. ii, 1834. p. 383 ; G.ptilosus, 

 Thoms. Ofv. 1860, p. 180; Kieff. Spp. Hym. d'Europ. 1904, 

 pp. 91, 501. 



A specimen of this genus with both the thoracic nodes bearing 

 erect white pilosity (that on the anterior node distinguishes it 

 from the remainder of the genus) occurred to me among dead 

 leaves of bracken in shallow rabbits' scratchings in a sandy bank 

 at Icklinghara, in Suffolk, on June 6th, 1916 ; it w'as running 

 among the debris in company, not ouly of the two ants Tetra- 

 morium caspitum and Lasius niger, but also of males and females 

 and nymphs of the rare Capsid Systellonotus tnguttatns, said by 

 Saunders to occur with ants. Another specimen occurred to me 

 in the same parish, but upon the sandy "plains," some mile 

 and a half from the above locality, in company of Lasius alienus 

 beneath Erodium cicutarinni on the preceding Juneljl^h. The 

 species figures in Marshall's 1873 catalogue as British upon an 

 erroneous foundation, since G. striatns was mistaken for it. 



This well-authenticated association of Gonatopi with ants is
