JTomalofa.] STAPHYLINIDiE. Ill' 



sparingly, punctured, sixtli almost impunctate ; legs yellow, sometimes a 

 little pitchy. L. 2| mm. 



Male with the uj^per plate of seventh segment of hind hody with a 

 notch on middle of hind margin, lateral margin on each side produced 

 into a small tooth ; third and fourth joints of antennae strongly ciliated, 

 and thorax impressed in middle. 



At sap of felled trees ; also in cut grasi?, moss, &c. ; occasionally in sandpits ; not 

 common ; Mickleliam, D;irenth Wood, Weybridge, West Wickliam, Sittingboiirne, 

 Shirley ; Littlington and Hurst, Sussex ; Winchester ; Knowie, near Birmingham ; 

 Repton, Burton-ou-Trent ; also recorded from Manchester in fungi, but this may be 

 in error as its habitat is usually different ; Scotland, local, Sohvay district only ; 

 ThornhiU (Sharp). 



K. sodalis, Er. {incisa, Mais, et Rey, Atheia sodalis, Thorns.). 

 Rather like the preceding, but larger ; somewhat convex, rather shining, 

 black with the elytra obscurely brownish, or nearly black ; head rather 

 small, finely and indistinctly punctured ; antennae somewhat stout, 

 thickened towards apex, pitchj'- with paler base, joints 2-3 nearly equal, 

 fourth about as long as broad, 5-10 gradually more distinctly transverse, 

 eleventh as long as the two preceding together ; thorax transverse, but 

 not so plainly as in the preceding species, narrowed in front, distinctly 

 and not finely punctured, with a broad obsolete impression in front of 

 'scutellum, sometimes appearing double ; elytra longer than thorax, thickly 

 and plainly punctured and pubescent ; hind body shining, segments 2-4 

 distinctly l3ut not thickly punctured, 5-6 nearly impunctate ; legs reddish 

 yellow. L. 3 mm. 



Male with the hind margin of upper plate of seventh segment 



emarginate and very obsoletely crenulate. 



In decaying fungi, dead leaves, moss, &c. ; sometimes at sap ; not uncommon ; 

 Loudon district generally ; Tonbridge ; Birmingham district ; Bewdley ; Needwood ; 

 Manchester; N'<irthumberlaud district; Scotland, local, Forth, Dee, Sohvay, and 

 probably other districts. 



K. humeralis, Kr. {fennica, J. Sahib., Atheta palUdicornis, Thorns., 

 Homalota {Mycota) humeralis, Muls. et Eey). Very like H. sodalis 

 but differs, according to IMulsant and Rey, in being generally darker, 

 except as regards legs ; in this respect, however, it must be variable, as 

 Dr. Sharp (Ent. Mo. Mag. viii. 247), comparing it with H. sodalis, speaks 

 of it as " smaller, with paler elytra and antennae," and his single specimen 

 certainly presents these characters in a marked degree; the antennae are 

 decidedly shorter with the fifth to the tenth joints more strongly 

 transverse ; the elytra are shorter, and the hind body is even more 

 sparingly punctured ; in the male the hind margin of the upper plate of 

 seventh segment of hind body is scarcely sinuate, and finely and 

 obsoletely .crenulate, the outside crenulations being the strongest. 

 L. 2| mm. 



Very rare ; Cirencester (McNab) ; Winchester (Horner) : in France this species 

 occurs rarely among dead leaves and in old faggots on which there is fungoid growth.
