distant at their base, somewhat approximate in pairs on the 

 hinder and outer portions of the disk, and are each impressed 

 by a single row of distinct punctures ; deeply impressed in front, 

 they become shallower and their puncturing less distinct below 

 the middle, and towards the apex of the elytron are quite obso- 

 lete; the 9th and 10th rows are placed at a greater distance 

 from the adjoining striae than any of the other pairs ; w^ithin the 

 outer border is a deep impunctate sulcation, which extends the 

 whole length of the margin. Hinder thighs not extending be- 

 yond the elytra, their under surface furnished near the apex 

 with a short ridge, either extremity of which is armed with a 

 short tooth ; hinder tibiae with the basal half curved, the apical 

 half nearly straight, the apex not raucronate; on their inner 

 surface at the base is an obtuse tubercle.

Head punctured, a flattened triangular space on the forehead, 

 impressed on the centre of its basal margin with a deep fovea; 

 epistome smooth, impunctate, impressed with a deep longitudinal 

 groove; antennae as long as the head and thorax, black; the 

 black patch on the face is transverse, and often extends quite 

 across between the eyes ; the latter prominent, their inner mar- 

 gins narrowly and obliquely notched. Thorax rather broader 

 than long, sides obtusely angled at their middle, deeply con- 

 stricted just behind their apex; above subcylindrical, trans- 

 versely grooved near the base and again in front, the anterior 

 sulcation running into the lateral constriction ; surface shining, 

 subrcmotcly punctured. Scutelluni triangular, its apex notched. 

 Elytra parallel, dehiscent at their apex, subelongate, upper sur- 

 face rather more closely punctured than the thorax, longitudi- 

 nally depressed along the suture, impressed at the base within 

 the shoulders ; basilar space obsoletely raised ; on each elytron 

 are three large black spots — one, oblong, at the base, extending 

 over the humeral callus, a second, transverse, placed just before 

 the middle, arising jtist within the lateral border and extending 

 across nearly to the suture, and a third, subapical, triangular, 

 its anterior border notched. Hinder thighs in the c? strongly 

 inci-assate, armed beneath near the apex with a stout tooth ; in
