PIIYSIMERUS. 



transverse, rectilinear, at the base slightly constricted and transversely 

 depressed ; the anterior angles subacute ; the surface finely flavo- 

 pubescent, punctate, flavo-rufous. Scutellum triangular, fuscous. 

 Elytra much broader than the thorax, depressed, punctate-striate 

 (the punctures being broad and shallow, and the striae almost ob- 

 solete : at the apex the punctures are obsolete) ; the surface rufo- 

 flavous, clothed throughout (more or less) with a fine ashy pubescence : 

 two transverse bands of a rufo-piceous colour (the one at the hume- 

 ral angle, and the other medially) extend from the margins to about 

 the fifth stria, where they are obliquely inflected (in the direction of 

 the apex) to the suture ; these angulated fasciae are broader and 

 more prominent in some examples than in others ; in all they are 

 well-defined. Antenna filiform, sufficiently robust, flavous, the first, 

 and also the sixth and seventh joints being rufo-fuscous. Legs flavo- 

 testaceous throughout.

 and the Rev. H. Clark. 



Besides the differences in colouring and marking (which appear to 

 be tolerably constant) between this and other allied species, struc- 

 tural differences are apparent : in P. angulo-fasciatus the base of the 

 thorax is more constricted than in P. brevicollis, and the surface of the 

 thorax is more equate than in P. bituberculatus ; in the sculpturing 

 of the head, also, important differences may be traced. 



21. Physimerus bituberculatus. 



P. oblongo-ovatus, latus, depressus, subpubescens, Jlavo-rufus ; ca- 

 pite breui, ad basin longitudinaliter carinato, punctato ; ihorace 

 transverso, rectangulari, ad basin depresso, antice elevato, rufo- 

 fusco, antice et ad latera rufo ; elytris latis, depressis, punctato- 

 striatis, rufo-fuscis, ad humeros, et juxta apicem transverse rufo- 

 fiavis ; antennis filiformibus, Jlavis ; pedibus flavis, fernoribus 

 postitis fusco suffusis. 



Long. corp. 2 lin., lat. 1 lin. 



Oblong-ovate, broad, depressed, subpubescent, flavo-rufous. Head 

 short, transverse, slightly depressed, hardly produced ; eyes large 

 and prominent; between the eyes, and above the insertion of the 

 antennae, is a small T-shaped depression, while above it, extending 

 to the base of the head, is a longitudinal carination ; surface finely 

 punctate. Thorax transverse, rectangular ; the anterior angles de- 

 pressed ; this depression extends in an oblique direction to the mid- 

 base, giving a prominence to the anterior part of the thorax, which 

 divides itself (very distinctly by colour, and also, less distinctly, by
