A/euchara.] stapiiylinid;e. 17 



elytra are not so distinctly sinuate at the posterior angles ; the liind 

 body is much more sparingly and fcel)ly piuictured than in eitlier of 

 the two preceding species, with the exception of the apical segment, 

 which is thickly and phiinly punctured ; the slender antennae and 

 narrower thorax, as well as the duller appearance of the thorax and 

 elytra, will serve to separate it from A. li/gtf^a and A. moesta, between 

 ■which two species it is intermediate as regards the punctuation of the 

 hind body. L. 3^-4 mm. 



Rare; in decaying vegetable refuse; first introclueed by Mr. Bold (Ent. Mo. Mag. 

 vii. 275) on specimens from Newcastle-on-Tyiic ; Scarborough (pigcou-cotes, Lawsoii); 

 Leamington, Knowle near Birmingham, and Rugley Park (W. G. Blatch); Scotland, 

 Braemar (Sharp). 



A. moesta, Grav. {Darijodma {PoJi/rJ/ara) mocsta, Grav.). This 

 species bears a somewhat close resemblance to A. laim(/mosa and its 

 allies, but may at once be distinguished by its almost impunctate and 

 shining hind body, the apical segments of which are almost entirely 

 smooth; as a rule it has the legs and antennae more or less reddish, and 

 the elytra are sometimes dai'k reddish brown ; the antennae are more 

 strongly thickened and have the penultimate joints more transverse than 

 in A. lanu(jinosa or A. villosa, and in this point it resembles A. h/gd'a, 

 from which it may be easily separated by its sculpture ; it is broader 

 and less linear than A. villosa, and has the elytra much more coarsely 

 punctured ; in some points it resembles darker specimens of A. moerens, 

 but has the antennae less thickened and the hind body less evidently 

 punctured. L. 3-4 mm. 



Male with the dorsal plate of seventh segment of hind body truncate 

 or almost truncate, and finely and oljsoletely crenulate on apical border, 

 ventral plate prolonged and furnished with long cilia. 



In moss, uung, haystack refuse, sea-weed, &c. ; comrann and widely distributed 

 throughout England and the southern part of Scotland ; Ireland, Dublin and Waterford, 

 and probably widely distributed. 



A. mycetophag-a, Kr. (5a77/of?ma {Polijcliara) nif/refopJtaffa, 'Sluh. 

 et Key). Rather elongate, broader in front, and much narrowed behind, 

 finely and rather thickly pubescent ; pitch-black, with the elytra, apex 

 of hind body, and often the apex of the several segments of the latter 

 reddish brown ; head finely punctured, antennae pitchy with reddish 

 base, rather strongly thickened from the hfth joint inclusive, joints 

 5-10 strongly transverse; thorax broader than long, narrowed in front, 

 with sides strongly rounded, finely and rather thickly punctured ; elytra 

 hardly as long as thorax, strongly transverse, very thickly and somewhat 

 rugosely punctured ; hind body gradually but distinctly narrowed from 

 base to apex, thickly punctured towards base, rather sparingly towards 

 apex ; legs red. L. 3|-4 mm. 



Male with the seventh segment of hind body slightly emarginate and 

 obsoletely crenulate on apical margin.
