CARDANUS BOILEAVI. 191 



thickened densely punctate margin; the front margin of the 

 head regularly concave; the clypeus angularly notched, the 

 sides of the notch convex, the lateral angles pointed. The 

 mandibles smooth and shining, strongly curved, the tip 

 slightly directed upwards and forwards; a blunt tooth, 

 directed inwards and upwards, is present at the base. The 

 surface of the head shows a regularly curved smooth im- 

 pression which unites the emarginations between the lateral 

 front angles and the ocular canthus, this impression is, 

 however, slightly interrupted in the middle by some large 

 and deep punctures. At the inside of each eye a raised and 

 coarsely punctate triangle is present the tops of which are 

 separated from each other by a less punctate space. A streak 

 along the front margin of the head is smooth and im- 

 punctate. 



The thorax is distinctly longer than broad ; the anterior 

 angles are protruding and narrowly rounded; the sides are 

 not quite parallel, the thorax being broadest at about one 

 third from the base; the basal third of the lateral margins 

 is distinctly crenulate; the basal margin is slightly bisinuate 

 and accompanied by a narrow groove which has large 

 punctures at its bottom. Just behind the middle of the 

 front margin a distinct tubercle is visible which is followed 

 by an elongate more or less rhomboid space of large deep 

 punctures extending to the base of the thorax. Very fine 

 punctures are scattered over the surface intermixed with 

 some larger ones which are arranged in three pairs of 

 groups of which the most distinct one is situated on the 

 basal half midway between the central patch of punctures 

 and the lateral margins. Near to the front margin of the 

 thorax the punctures are very distinct and close together. 



The elytra are not quite as broad as the thorax, sub- 

 parallel, inconspicuously narrowing to the apex which is 

 regularly rounded; the basal margin is concave, the shoulders 

 are prominent, the lateral margins crenulate at the shoulder- 

 region ; the sutural region is depressed on the basal half 

 of the elytra, on the apical portion the first costa lays in
