3. r )2 CLAVICORNIA. [Mycetopliagus. 



variable in size, and occasionally those before apex are very small or 

 even absent ; sometimes the spots are entirely wanting, but I have 

 never seen a British specimen of this variety ; antennae gradually 

 thickened to apex, with the last joint long and pointed, joints 1-6 red, 

 7-10 dark, last joint more or less brightly yellow ; thorax transverse, 

 as broad behind as elytra, strongly narrowed in front, base sinuate, pos- 

 terior angles projecting, upper surface distinctly and rather thickly 

 punctured, base with a deep fovea on each side ; elytra with punc- 

 tured striae, interstices finely punctured ; under-side and legs reddish. 

 L. 5-6 mm. 



In fungi on old stumps of trees, under loose bark, &c. ; local, but common in some 

 districts ; London district, common and generally distributed ; Wicken Fen ; 

 Glunvilles Wootton; Netley ; Exeter; Swansea; Newnham, Gloucestershire; Sal- 

 ford Priors ; Hunstauton, Norfolk ; Repton ; Sherwood Forest ; Scarborough ; Ripon ; 

 not recorded from any English district north of Yorkshire, and mentioned by Dr. 

 . Sharp as very rare in Scotland, without any locality being given. 



IMC. piccus, F. Oblong, ferruginous or pitchy-red, with the head 

 and elytra usually darker than thorax, under- side bright brownish-red ; 

 the elytra are furnished with more or less variable waved spots and 

 markings, of which two fascia towards base, which often meet at suture, 

 appear to be the largest and most constant. Erichson (Naturgesichte 

 der Insect. Deutsch. iii. 408) mentions eight distinct varieties of 

 coloration ; antenna? ferruginous, penultimate joints often darker ; thorax 

 shaped much as in the preceding species, but with the sides rather more 

 rounded towards the front, upper surface thickly punctured ; elytra with 

 fine punctured strife, which become obsolete towards apex, interstices 

 finely punctured ; pubescence as in the other species light on the light 

 spots and darker on the dark spots ; legs testaceous yellow. L. 4-4| mm. 



In fungi on old trees, &c. ; not common ; Forest Hill, Surrey ; Lee, Kent ; Nor- 

 folk ; Suffolk; Hastings; New Forest ; Bristol ; Swansea ; Shrewsbury ; Need wood ; 

 Sherwood Forest ; Manchester district ; not recorded from the Northumberland and 

 Durham district or from Scotland. 



1*1. atomarius, F. This species is easily distinguished from any of 

 the others by its deep black colour and the small yellow patches on 

 elytra, and also by the plain longitudinal impression on thorax before 

 scutellum; it is of long elliptical form, finely pubescent; head distinctly 

 punctured, antenme reddish-brown, penultimate joints usually darker, 

 last joint lighter at apex ; thorax as broad behind as elytra, closely and 

 strongly punctured, hind margin bisinuate, posterior angles well marked, 

 projecting ; elytra with a small transverse waved band behind middle, 

 some larger patches towards base, and many small dashes and markings, 

 yellow ; disc somewhat depressed, strise rather well marked and dis- 

 tinctly punctured, interstices finely punctured ; under-side blackish or 

 brownish ; legs brownish-red, femora darker. L. 3^-4^- mm.
