slightly virescent, each with an irregular testaceous basal patch 

 and interrupted apical fascia. The antenna?, the parts of 

 the mouth, the margins of the thorax and elytra, and the 

 legs pale ferruginous. Head dark brown or piceous, about 

 the same breadth before as behind the eyes, upper surface 

 exceedingly densely and pretty deeply corrugated all over, so 

 much so as to appear almost opaque ; clypeus transverse, nar- 

 rowest in front, wrinkled, separated from the front by a marked 

 straight line ; labrum about the same length as the clypeus, 

 narrowest in front, truncate, with a longitudinal groove in the 

 middle in front, and a puncture on the margin near the apex ; 

 mandibles sharp and projecting, but not so much so as in the 

 next species ; terminal joint of palpi subcylindric and subacumi- 

 nate. Antennae about the length of head and thorax, the end 

 of the fourth, the fifth and remaining joints flattened. Eyes 

 very large. Thorax considerably broader than head, cordiform, 

 gently convex in the middle, and with very broad and deeply 

 reflexed margins, which have here and there a few large punc- 

 tures scattered in the bottom of the hollow; the disk very 

 faintly wrinkled across, and with a dorsal longitudinal stria ; 

 fuscous, but paler than head, in some lights faintly virescent ; 

 margins semitransparent and broadly testaceous; posterior 

 angles nearly right-angled ; base truncate. Scutellum testaceo- 

 fascous, impunctate. Elytra shining, broader than thorax, but 

 not twice as broad, somewhat convex ; base nearly straight ; 

 sides very slightly expanded ; pitchy black when looked at from 

 in front backwards, virescent when looked at from behind 

 forwards, deeply punctate-striate ; eight striae, besides scutellar 

 and marginal strise ; the interstices convex and apparently im- 

 punctate; but with a very powerful lens, a few punctures of the 

 faintest description may be traced, disposed in a row along each 

 interstice; a fovea on the inner side of the second interstice near 

 the apex, another about one-third from it, and another on the 

 third stria about the same distance from the base ; a series of 

 round, flat-bottomed fovea? on the marginal interstice ; apex ob- 

 liquely truncate and excised, the exterior apical angle flattened and 

 rounded ; the seventh stria sweeps round at the apex, enclosing 

 those nearer the suture ; margin inflexed ; inflexed portion and 

 raised edge of margin testaceous ; a transverse testaceous patch 

 about one-fourth from the base is disposed as a series of longi- 

 tudinal stripes occupying five interstices as follows :— the longest 

 stripe between the third and fourth stria?, the second longest 

 between the second and third, the shortest between the fourth 

 and fifth, and the next shortest (two of nearly equal length) 

 between the fifth and seventh ; a transverse, interrupted, testa-
