j^ its short, convex form, pale castaneous colour, remote and almost invisible puncta- 

 tion, and large yellow antennae, of which the fifth joint is much longer than the 

 sixth. 



I cannot perceive any difference between some specimens which have been sent 

 to me under the names of Orth. pilosiusculus, Duv., and Orth. anxiiis, Rey, and 

 the present species ; but as I have not yet been able to examine the original de- 

 scriptions of those species, I cannot speak positively as to their identity. 



Orthoperus mundus, sp. n. 



L. c. ^"1 lin., = •75-'87 mm. Latus, rotiindatns, sat depressus, aterrimus, alu- 

 taceus, hand nitidus ; capite magno, distincte alutaceo, oculis prominentihus ; pronoto 

 late I lato, ad basim latissimo, minute alutaceo, impress io7iibus ttihus levibus ad basim 

 notato, una mediali et utrinque altera laterali, disco impunctato, lateribus rotimdatis 

 et marginatis, margine ipsa, dilutiori, margine basali scutellum versus multum pro- 

 ducts angulis fere reef is ; elytris capite atque pronoto parum latioribus, sesqui 

 longioribus, prope media latissimis, sat profunde alutaceis, punctis parvis, equi- 

 distantibus, striatim dispositis notatis, lined suturali impressis, lateribus valde ro- 

 tundatis, fortiter marginatis margine dilutiori, apice valde rofundato, dilutiori ; 

 abdominis pygidio hand exserto ; pedibus brevibus, gracillimis, Jlavis, tibiis an- 

 terior lb us fortiter incurvatis ; antennis sat longis, flavis, clavis nigro-piceis, articulo 

 qiiinto sexto longiori, liaud latiori. 



Body broad, rounded, slightly depressed, deep black, alutaceous, not shining. 

 Head large, minutely alutaceous ; eyes large and very prominent ; antennse rather 

 long, yellow, with the club pitchy-black and the fifth joint longer, but not broader 

 than the sixth. Thorax broad, widest at the base, minutely alutaceous, witli three 

 faint impressions near the base, one in the middle and one on each side, disc im- 

 punctate, sides rounded and margined, with the margin pale, basal margin much 

 produced towards the scutellum, with the angles nearly right angles. Scutellum 

 moderate, obtusely triangular. Elytra rather broader, and one-half longer than the 

 head and thorax, widest near the middle, rather deeply alutaceous, marked with 

 small equidistant punctures arranged in striae, and an impressed line on each side of 

 the suture, sides much rounded and strongly margined, with the margin pale, apex 

 much rounded and pale. Legs short, very slender, anterior tibiae much incurved. 

 TJnder-parts piceous. 



Differs from all other species in its rounded and depressed form, large head and 

 prominent eyes, deep black colour, and in sculpture. 



This very distinct species was often found by my brothers and myself in a small 

 spot near Weston-on-the-Green, in Oxfordshire, but I have never seen an example 

 of it in any other British or foreign collection which I have examined, nor have we 

 ever met with it in any other locality. 



Orthopeeus coriaceus, Eey. 



Orth. coriaceus may be known by its small size, oval and rather narrow shape, 

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

 antennse, and long slender legs. 



This species has also been sent to me under the name of Orth. pilosiusctdus, 

 Duv.
