Black, not very shining, convex, without hair or setae, except 

 upon the legs, which are fairly slender. The eyes rather large. 

 The ])ronotum with an oval impression in tlie middle, d'>ep 

 in front and extending from front to hind margm, and tlie 

 elytra broadly roimded behind, narrowly flattened at the sifles 

 and very dee])ly grf)oved, except at the sides, which are strongly 

 and closely punctured. 



$. Elongate-ovate and very convex. The hedd is strongly 

 and very closely punctured, the sides nearly straight, obtusely 

 angular in front, diverging and ending abruptly behind the 

 eyes. The mandibles have each a large triangular sluirj) tooth 

 at the inner edge. The pronotum is ever^^where coarsely and 

 very closely punctured. The lateral margins are irregularly 

 serrate, very feebly curved in front, strongly rounded be^'ond 

 the middle, the base straight and hind angles absent. Thi^ 

 scutellum bears a few punctures. Tlu^ dorsal grooves of the 

 elytra are very deej), the intervals rather closely and irregularly 

 and the sides and aj^ices rugosely pimctured. The lateral 

 edges are gently curved and finety serrate. The menlum, 

 the sides of the metnsterrmm and the bases of the ventral sterniteft 

 are coarsely pmictured. 



(J. Rather parallel-sided and sub-cylindrical. The head is 

 flat, sparsely or moderately ])unctured, with tlu' fnmt margin 

 very gently excised, the sides almost straight and ])arallel , endiuix 

 rather abruptly behind, with a sharj) triangular tooth beliind 

 the eye. The pronotion is finely and scantily, moderately, or 

 very strongly and closely punctured, with the lateral edges 

 irregularly and rather finely crenate, nearly straight and 

 parallel to far beyond the middle, where they meet the base in a 

 very blunt angle. The sciitellum bears a few punctures. Tlie 

 elytra bear six very deep but not very regular dorsal striae, the 

 intervals are finely punctured and the sides, as well as the base 

 and a])ices, are rugosely i)unctiuvd. The shoulders are acutely 

 angular and the lateral margins finely crenate in front. The 

 mention is opac]ue, the sides of the metasternnm are rugose aiid 

 the ahdivnen is scantily ])unctured. 



Variation of the male. Small males resemble the female.
