of the îuitennal depression strongly jjunctured ; antennal tuber- 

 cles smooth and shining. 



Clj^peus roundly narrowed towards the apex, which is rufous. 

 Thorax strongly and closely punctured ; the parapsidal furrows 

 deep ; the pronotum is more closely punctured than the raeso- 

 uotum, and the latter than the scutellum ; the latter is bilo- 

 bate at the apex ; the lobes are not very prominent. Meta- 

 notum coarsely, irregulated reticulated; its central area is 

 obliquely narrowed at the base ; shortly above its middle are 

 2 stout, irregular transverse keels, the lower one being also 

 in the middle of the area ; the lower part is of equal width, 

 the upper part roughened, the lower smooth; the sides of the 

 metanotum become gradually, roundly narrowed, the base being 

 dilated. Abdomen sessile, smooth ; as long as the thorax ; the 

 last segment does not project much ; the apical segments are 

 covered with rufous pubescence ; the ventral more densely, 

 with longer rufous pubescence. 



Except at the base above and the apex below the meso- 

 pleurse are stoutly striated in the centre ; the part bordering 

 the striated part at the base is roundly curved ; on the lower 

 part of the border are, above, 3 large round foveae, below, 4 

 more widely separated ones, these being edged at the apex 

 by a shining border. The keel on the hind femora is black ; 

 it occupies the bnsal two-thirds ; the part inside the keel is 

 densely covered with white pubescence. The hind coxae have 

 their upper basal half black. The punctures on the pronotum 

 are closer and run more into each other than do those on 

 the mesonotum. There is a smooth, shining line on the malar 

 space. The anterior coxa3 are black, not red like the others. 

 The antennse are 12-jointed and are placed immediately over 

 the clypeus. Hind tibise slightly, roundly dilated on the inner- 

 side ; the end bears a stout black, and a narrower red spine ; 

 they are about one third longer than the tarsi ; behind the 

 basal 2 joints of the tarsi are of equal length.
