616 Capt. T. Broun on new 



at eacli side behind the eye it has an angular lobe which 

 projects quite as far as the lateral margin o£ the thorax, this 

 causes the head to appear constricted behind that point ; its 

 surface is moderately finely punctured ; the punctuation, 

 however, becomes finer and more distant towards the middle 

 of the base. Thorax 2^ lines long by 5 broad, apex widely 

 but slightly emarginate ; the lateral margins are thick and 

 somewhat reflexed, but become obsolete near the rounded 

 front angles ; the sides are almost straight, but near the base 

 are obliquely and rather abruptly narrowed, so that the 

 posterior angles are not at all well marked ; the base is 

 almost quite truncate ; its punctuation is rather coarser than 

 that of the head, but becomes finer and more remote towards 

 the front. Elytra narrower than thorax, rounded behind, 

 humeral angles nearly rectangular ; their side margins are 

 like those of the thorax ; their sculpture consists of irregular, 

 moderately close, and coarse punctures, and two or three ill- 

 defined linear elevations on each. 



TihicB hispid, the anterior with a stout inner calcar reaching 

 the extremity of the third tarsal joint, the external apex 

 bidentate ; the intermediate obviously angulate outwardly and 

 with a small median tooth ; the posterior triangulate at the 

 extremity and grooved along the hind face. 



Mandibles large, curvate, bifid at apex ; near the base on 

 each there is a short anguhu' tooth just below the level of the 

 labrum ; at the middle on the inside of each mandible there 

 is a large tooth, directed upwards, which is bifid* at the apex, 

 and near the front on ttie lower surface there is a short 

 angular projection j none of these inner teeth touch the 

 corresponding ones when the mandibles are closed. 



Underside rather finely punctured. 



The form of the male is like that of L. ithoginis (no. 19G6). 



The mandibles differ materially from those of that species 



and L. Helmsi, and the lobe-like projection behind each eye 



does not occur in any other species known to me. % incog.
