'^. — Cnmjioden silvestrii, sp. n. (fig. 7 a). 



= C. staphyJinus Silv., non Westwood. 



See i*einarks under description of C. stapln/linus. 



Silvestri examined British material from Dublin, and Leamside and 

 Pensbaw, Co, Durham. Curiously enough he did not receive specimens 

 of our commonest British Campodea, which I now bring forward as the 

 tiiie C. staph ylinus, falling into Section II. 



ExGLi.yD : Lizard Pt., Cornwall, April 1915, and Swansea, Jan. 

 1916 (P. A. Buxton). Ringwood, Hants, Aug. to Dec. 1912 (C. B. 

 Williams). I have only seen a few examples (all juvenile) from 

 Northumberland and Durham, while gardneri and staph ylinv.s are to 

 be found everywhere. 



Irelaxd: Ballvcastle. Co. Anti-im, Aug. 1915 {X. H. Foster). 



4:. — Campodea gardneri, sp. n.* (fig^- 5 k 7). 



Length l-9-2'3 mm. White. Minor setae elongated, pointed, simple; 

 much as iu $ilvestrii, but fewer and longer, being intermediate between that 

 species and redii Silv. Major setae as in tig. 7. Antennae 19-segmeuted, 

 about 0"-4 the length of the body, Xotum with all the major setae present. 

 Tergites without submedian major setae: 5-9 with sublateral posterior, and 

 lateral major setae. Cerei 8-10 segmented, very similar to the cerci of 

 C. silcestrii XM. plu-^iochaeta Silv.. but noticeably stout basally, less than half 

 the length of the insect, 8-10 segmented. Apical seta of style with a single 

 branch near base, subapical S'^ta branched towards middle, and the third main 

 seta branched distally. 



Apart from its small size this species differs from sUvestrii {staphylinus 

 Silv.) and its variety plusiochneta very sharply iu the character of the major 

 setae and of the type of stylus. In size it more closely approaches redii Silv. 

 (165 mm. long), but in that species both the major and minor setae are longer 

 and, in the latter case, fewer, whilst the sublateral posterior major setae are 

 found on tergites 4-9,

 A large sj^ecies, described fi-om examples taken at Berkhamsted 

 {Coinage). 



* I flml particular pleasure in dedicating this species to mj firiend Mr. John Gardner, F,E.S,, 

 of Hart, as a small mark of appreciation for the help and encouragement I have received at his 

 hands since I first turned to Entomologr.
