O. corticalis, Eedtenbacher, Faun. Aust. p. 299, 1858. 



L. c. y% lin. — 1 mm. — Ovalis, valde convexus, nitidas, indistincte alutaceus, 

 fere glaber, rufo-castaneus ; capitc modico ; pronoto parvo, antice levissime exciso, 

 angulis fere obsoletis, ad basim latissimo, lateribus circulariter rotuudatis, distincte 

 marginatis, linea transversa ad basim impresso, margine basali scutellum versus 

 leviter product;i, angulis obtusis ; dijtris capite atque pronoto multum latioribus et 

 plus quam duplo longioribus, prope media latissimis, levissime alutaceis, punctis 

 exiguis, remotis, striatim dispositis, notatis, lateribus leviter marginatis, valde 

 rotundatis, apicibus obtusis ; abdominis jjygidio exserto ; pedibus longis, Isete 

 flavis, tibiis anterioribus valde elongatis et fortiter incurvatis ; antennis longis, 

 robustis, Ifete flavis, articulis duobus basalibus magnis, quinto sexto lougiori, 

 baud latiori, clavis valde incrassatis. 



Head moderate ; eyes rather small ; antennjE long and robust, bright yellow, with 

 the two basal joints very large, fifth longer but not broader than the sixth, and 

 the club very much iucrassated. 



Thorax small, very slightly excised in front, with the anterior angles almost obso- 

 lete, widest at the base, sides circularly rounded and distinctly margined, 

 indistinctly ahitaceous, with a transverse impressed line near the base, basal 

 margin slightly produced towards the scutellum, with the angles obtuse. 



Scutellum small, triangular. 



Ehjtra large, much broader and more than twice longer than the head and thorax, 

 widest near the middle, very faintly alutaceous, marked with very minute 

 remote punctures arranged in strije, sides slightly margined, much roimded, 

 with the apex obtuse. 



Abdomen with the pygidium exposed. 



Legs long, bright yellow, with the anterior tibiae very long and strongly mcurved. 



Under parts pale castaneous, with the venter paler. 



Differs from 0. brunnipes in its oval rounded form, the small size, slight emargina- 

 tion, and obsolete anterior angles of its thorax, rounded sides of its elytra, and 

 bright yellow and differently formed legs and antennte. 



Habitat, Europe. Taken by myself in Sherwood Forest. 



Orthoperus Japonicus, sp. u. 



L. c. y^'o lin. = 1 mm. — Late ovalis, convexus, nitidus, regulariter et sat pro- 

 funde punctatus, totus castaneus ; capitc minime exserto, oculis parvis, baud 

 prominentibus ; pronoto parvo, modice et remote punctato, interstitiis glabris, 

 nitidis, linea basali distincta et coufertissime punctata, lateribus leviter mar- 

 ginatis, margine basali leviter siuuata, anguHs acutis ; ehftris sat magnis, capite 

 atque pronoto latioribus et duplo longioribus, pone media latissimis, pronoto 

 magis profuude et magis confertim punctatis, interstitiis alutaceis, lateribus leviter 

 marginatis, apice rotundato ; pj-gidio vix exserto ; pedibus brevibus, gracillimis, 

 Isete flavis ; antennis modicis, ad bases laete flavis, apices versus obscurioribus. 



Body broadly oval, convex, shining, regularly and rather deeply punctured, entirely 



castaneous. 

 Head very little exserted ; eyes small, not prominent ; antennte moderate, bright 



yellow at the base and dusky towards the apex. 

 Thorax small, moderately and remotely punctured, with the interstices smooth and 



shining, basal line distinct and very closely punctured, sides faintly marguied, 



basal margin faintly sinuated, with the angles acute. 

 Scutellum very small, subtriangular, and punctured.
