margins white, margins and apical points o£ the clypeus black, 

 antennae and palpi fulvous-red. Thorax transverse, strongly 

 rounded at the sides in front, posterior angles rounded, the base 

 slightly emarglnate before the scutellum, coarsely but not very 

 closely punctured, a narrow lateral border and sometimes two 

 small discal spots white. Scutellum coarsely punctured with 

 a smooth central line. Elytra with two broad discal costae and 

 the sutural margin smooth, the interstices with very coarse 

 irregular variolose punctures, the sides more finely punctured, 

 the outer margin with a narrow white border dilated inwardly 

 at the sutural angle. Pygidium very finely strigose, a large 

 spot on each side, sometimes united at the apex, white. Beneath 

 broadly Avhite at the sides, centre of metasternum greenish, 

 mesosternal process short and obtuse ; abdomen broadly im- 

 pressed and with large transverse white spots in the centre, 

 underside of the anterior and posterior femora and a marginal 

 band on the intermediate femora white, anterior tibiae with two 

 strong lateral teeth, the four posterior tibiae with one small 

 external tooth. The female has the legs stouter, the anterior 

 tibiae broader, the four posterior tibiae Avith a larger tooth and the 

 abdomen convex and with only two or three small basal spots 

 in the centre. Length 11-13 mm.

Eeceived from Dr. Candeze with the preceding species to 

 which it is closely allied, but differs in having the clypeus more 

 narrowed in front, the thorax broader and more strongly rounded 

 at the sides, the costae on the elytra much broader, the meso- 

 sternal process more prominent, the upper surface less closely 

 punctured, the pubescence more sparse, and no white spots on 

 the elytra. The lateral bands on the thorax are abbreviated 

 l)ehind in some specimens and in others turned inwardly or 

 dilated at the jDosterior angles ; the white spots on the head also 

 vary in size and are sometimes entirely absent ; one of the speci- 

 mens before me has all the markings of an ochreous or creamy 

 colour instead of white.
