angled and simiate, shaped much as in the preceding species, posterior 

 angles plainly emarginatc, forming an acute angle with tlie basal margin 

 which slightly projects ; the general sculpture is moderately strong. 

 L. 2-2} mm. 



Male with the posterior femora slightly thickened, the intermediate 

 tibifB slightly curved, and the posterior sinuate on their inner side and 

 dentate in the middle. 



In putrid funp:i ; very local, but common where it occurs ; Aslitead, Clayprate, Til- 

 pate, Esher, Micklfham, Sliirley, Darcnth Wood, Merewortli, Sevenoaks," Chatham, 

 Sheerness, Tonbridge ; Norfolk ; Hastings ; Glanvilles Wootton ; St. Leonards 

 Forest ; New Forest ; Parkhurst Forest, Isle of Wight ; Devonshire ; Swansea ; 

 Somersetshire and Shropshire (Stephens) ; there are no northern records except 

 Solway district, very rare, " Raehills, Rev. W. Little," which requires confirmation ; 

 Stephens says that he used frequently to take it at roots of old fir trees near Hertford ; 

 in all probability there was fungoid growth in or near the spot in which the specimens 

 occurred. 



PHLCEOBIINiE. 



The single genus that forms this sub-family is distinguished from all 

 the other groups except the Proteininre by its transverse and sublinear 

 anterior coxae, which are not prominent ; it is by many authors classed 

 with the latter group, but is distinguished from it by the presence of a 

 single ocellus on the vertex, and by its shorter elytra ; the tarsi are all 

 five-jointed. 



PKZiCEOBZUZ^, Lacordaire. 



One species only is contained in this genus ; in general appearance it 

 is something like a Megartlirus, but may easily be distinguished super- 

 ficially by its large transverse head, shorter elytra, and more paralkd 

 form ; it is found in moss, &c., and is not uncommon in many parts of 

 the country. 



P. clypeatum, Mull, (corticale, Lac). Oblong, rather depressed, 

 of a dull reddish testaceous colour, with tlie head and disc of thorax often 

 darker, clothed with fine short and diffuse whitish pubescence ; head

 and rugosely punctured, with front border much raised, and dilated before 

 eyes in two small ear-like prominences, eyes large, black ; antennce about 

 as long as head and thorax together, black or blackish, with base and 

 apex reddish ; thorax very short, more than twice as broad as long, as 

 broad as elytra, bisinuate at base, which is broadly produced in middle, 

 and irregular and somewhat crenulate at sides, with evident central 

 channel ; elytra more than twice as long as thorax, rather strongly and 

 thickly sculptured ; hind body with at least four segments visible, finely 

 and asperately sculptured ; the sculpture of the front parts is often more 

 or less raised in minute prominences ; legs reddish testaceous. L. 2-
