the middle, close to the basal marghi ; scutellum transversely 

 curvilinearlj triangular, closely punctured : elytra more or 

 less sinuate-truncate (and a little wider than base of prothorax) 

 at the base ; a space, more or less open, between the base of 

 the elytra and base of prothorax ; sides very slightly rounded, 

 more or less gradually narrowed from the middle to the apex; 

 expanded lateral margins wide,reflexed or concave, transversely 

 and somewhat reticulately rugose-punctate, and studded with 

 small granules 5 disk closely, finely, and rather unifonnly 

 punctured, the interstices (especially at the sides) a little 

 elevated and reticulate and studded with indistinct minute 

 granules ; a series of narrow longitudinal costaj more or less 

 indicated, and an irregular row of rugged foveas, just within 

 the expanded margin, not extending to the apex : underside 

 brownish black, shining, finely punctured ; flanks of prothorax 

 more or less strongly (especially basally) longitudinally rugose, 

 the underside of the expanded lateral margins being transversely 

 rugose : legs dark brown, shining ; femora finely and not 

 closely punctured ; tibiffi closely submuricately punctured, the 

 anterior obliquely truncated at the outer side at apex ; hind 

 tibiffi quite straight ; tarsi and antenna reddish brown ; joint 

 8 of the latter subpyriform, 9 and 10 a little transverse, subtur- 

 binate, 11 large, broadly rounded cit apex. 



Length 8^-9 lines ; wndth of elytra 4|-4|- lines.

There is a very great amount of individual variation in the 

 species of this genus in the form of the prothorax (especially) 

 and elytra, and in the amount and intensity of the punctuation 

 &c. of their surface. 



In one of the three examples of the present species before 

 me (possibly a female, as similar differences exist in individuals 

 of the other species whereof a series has been obtained), the 

 form is more expanded or more broadly oval, the head and 

 prothorax are broader in proportion to their length, the sides 

 of the latter, instead of gradually narrowing in a slight curve 

 from base to apex, are subparallel to a little beyond the middle, 

 thence rapidly curvedly narrowed to the apex ; besides the two 

 ordinary fovea? at each side of the middle, at the basal mar- 

 gin, there is also a broad transverse line or depression, feebly 

 arched, subparallel and near to the basal margin ; the elytra 

 are broader and less narrowed behind, and the base is squarely 

 truncated ; and the punctuation on the prothorax and elytra 

 (especially on their disks) is more open. 



Altogether the largest, most expanded and 0])aque, and 

 least convex form in the u'cnus.
