distinctly wider behind than in front, the sides converging in front, 

 the posterior angles very round. Mandibles thick, triangular, finely 

 striated, sharply and closely punctured, obtusely dentate, the apical 

 tooth more acute in the smaller £ $ . Scape short, not reaching to 

 the posterior border of the head ; the three apical joints form a slight 

 club, nearly as long as the rest of the flagellum, the 1st joint of the 

 flagellum nearly as long as the following three taken together, 2nd- 

 7th joints wider than long. Clypeus with two strong carinae con- 

 tinued down from the frontal carinae, the anterior margin shallowly 

 sinuate. Frontal carinae flat, widely divergent posteriorly, continued 

 backwards as a fine ridge, which ends well behind the eyes in the $ 

 max., but in the £> $ media and minima not extending back beyond 

 the front of the eyes. The latter small, and situated behind the 

 middle of the sides. Pronotum with the anterior portion depressed, 

 forming a distinct neck, the posterior portion flat, and with distinct 

 but rounded anterior angles ; it is (excluding the neck) widest in 

 front, and twice as wide as it is long in the middle. The thorax is 

 constricted between the pro- and mesonotum, but the suture is not 

 clearly defined above. Mesonotum much narrower than the pronotum ; 

 its anterior two-thirds is level with the pronotum, and bears on each 

 side a strong rounded tubercle, behind which the surface slopes 

 steeply down to the meso-epinotal suture. The mesonotum is widest 

 across the tubercles. From the suture the epinotum rises upwards 

 for a short distance, and then slopes gradually downwards towards 

 declivity, which is moderately oblique. Close to the base, the dorsum 

 of the epinotum bears a pair of lateral tubercles, smaller and flatter 

 than those of the mesonotum. The epinotal spines are slightly 

 curved, and directed upwards, backwards and slightly outwards, and 

 are as long as the space between them at their base. The declivity is 

 margined laterally by ridges, which merge above into the base of the 

 spines, and below terminate in two small laminate teeth. 1st joint 

 of petiole as long as wide, widest in the middle, the dorsum flat or 

 shallowly concave, and bearing on each side, just above the steep 

 anterior face, an upward and outwardly directed spine. Second node 

 wider than long, convex above and in front, the posterior margin 

 depressed, the anterior angles dilated, narrower behind than in front. 

 Seen from the side, the spines of the first node hardly project above 

 the level of the dorsum of the 2nd node. Abdomen round, slightly 

 flattened above ; 1st segment a little longer than wide, truncate at the 

 base, with distinct lateral angles, and forming four-fifths of the abdo- 

 men above.
