144 CLAVicouNiA. [Orihoperus. 



collection, now in the possession of Mr. Mason, and was probably taken 

 at Scarborough. 



O. mundus, l^Iatth. Broad, rounded, slightly depressed, deep 

 black, alutaceous, not shining ; head large, eyes very prominent, antennae 

 rather long, yellow, M'ith the club pitchy-black and the fifth joint longer 

 but not broader than the sixth. Thorax broad, widest at the base, mi- 

 nutel}^ alutaceous, with three faint impressions near the base, margins pale, 

 posterior angles nearly right angles. Elytra widest near middle, rather 

 deeply alutaceous, marked with small equi-distant punctures arranged in 

 strise, margins pale, apex much rounded and pale ; legs short, very 

 slender, anterior tibia? much incurved ; under-side pitchy. L. | mm. 



This species was found rather commonly by the Rev. A. Matthews iiud his brothers 

 in a small spot at Weston-on-the-Green, Oxfordshire, but has never been met with 

 in any other locality. 



O. corticalis, Eedt. This is the largest of the pale castaneous 



species ; it may be known by its broadly oval form, pale castaneous 



colour, and bright yellow legs and antennas, of which the fifth joint is 



scarcely longer than the sixth ; the anterior tibiae are unusually long and 



much incurved. L. 1 mm. 



Two specimens have been taken by the Rev. A. Matthews in Sherwood Forest ; it 

 has also occurred at Lcith Hill, Surrey. 



O. punctatulus, Ma^th. Oval, moderately convex, shining, cas- 

 taneous, alutaceous throughout, with the elytra rather closely punctured ; 

 head moderate, eyes not prominent, antennre rather short, ferriiginous, 

 with the club black, sixth joint not smaller than the fifth ; tliorax small, 

 indistinctly punctured, with margins yellow ; elytra long, widest near the 

 middle, with apex obtuse ; legs rather large, ferruginous. L. | mm. 



One specimen taken by Mr. Matthews near Gumley, Leicestershire, is the only 

 example known. 



O. atoxnus, Gyll. This species may be distinguished by its short 

 oval and rather convex form, remote and almost invisible punctuatioii, 

 and large yellow antennas, of which the fifth joint is much larger than 

 the sixth ; legs yellow. L. -| mm. 



In vegetable and haystack refuse, &c., Leitli Hill, Surrey, Sbeerness, The Holt, 

 Farnham, Weston-super-Mare; Robin's Wood, Reptou ; Ireland, near Watcrford. 

 Mr. Matthews says that it is the most .'abundant of the British species ; it is probably 

 widely distributed, but often overlooked, owing to its minute size ; this also is most 

 likely the case with several of the other species. 



O. coriaceus, Key. This species may be known by its small size, 

 oval and rather narrow shai)e, somewhat bright, though dark, castaneous 

 colour, small head and thorax, large shallow punctures on elytra, robust 

 yellow antennaj, and long slender legs. L. f mm. 



Found in the London district, but I do not know the locality.
