second and third slender, both thickened at the apex, the last longest, fourth 

 and following nearly equal, somewhat moniliform, the apical joints closely 

 approximating, the terminal one large, nearly as long as the basal one, and 

 very obtuse. Falpi long, the apical joint very long and slender ; head 

 rounded, slightly exserted; thorax somewhat orbicular, polished; elytra 

 very short and entire ; abdomen broad, depressed, margined ; body glabrous ; 

 legs long, slender ; tibiae slightly ciliated ; tarsi moderate, posterior rather 

 slender, with the basal joint elongate.

Page lU. Genus 490 e. 'ROhlTOCYiKRk, Mannerheim. 



Antennae geniculated, the basal joint longest, clavate, second rather shorter 

 than the third, the remainder gradually increasing in thickness, truncate at 

 the apex, the terminal one generally oblong-ovate. Maxillary palpi elongate, 

 the penultimate joint long, subclavate, the terminal one very slender, 

 subulated ; labial very short, terminal joint slender, aciculate ; body rather 

 depressed, mostly sublinear behind; thorax wider than the head, with the 

 sides rounded; tarsi with the basal joint longest, the rest of equal length 

 with each other. 



In this genus I have included from Nos. 13 (Aleochara xanthopa) to 114 (Aleo. 

 glauca), with the exception of Al. Haworthi, which constitutes the genus 

 Zyras. 



Page 145. Genus 490 f. OLIGOTA, Mannerheim. 



Antennae faintly geniculated, nearly as long as the head and thorax, the basal 

 joint long and thick, cylindric, second stouter, globose, four following 

 extremely minute, globose, remainder abruptly thicker, broad, compressed, 

 and with the large rounded terminal one forming a club. Maxillary palpi 

 with the penultimate joint rather stout and globose, terminal minute and 

 acicular ; body sublinear, depressed ; head not concealed beneath the thorax, 

 which is wider than the head, short, transverse, slightly convex ; legs short ; 

 joints of the tarsi nearly equal. 



This genus corresponds with section C. b 2. (p. 145) and one new species.

Antennae geniculated, more or less thickened towards the apex, the second
