and another smaller one near the margin completethe sculpture 

 of the elytra, which are closely punctured and of a violaceous black 

 colour ; the pygidium and the underside are rugosely punc-tured, 

 the anterior legs nearly entirely fulvous, the posterior ones more 

 or less stained with black, the tarsi are broad and transverse. 



Hab. Brazil, Groyaz (Deyrolle). 



This species must surely be closely allied to C. lima Lac. and 

 several others contained in that section, but does not agree with 

 either of them ; the elongate shape and the coloration are similar 

 to those of C. elongata, but it is a very much smaller species and the 

 sculpturing of the thorax is quite different. In C. lima the latter 

 part is Hkewise provided with three tubercles, but they are placed 

 at the sides and not in front ; the elytra in the last-named species 

 are likewise provided with six tubercles, while here no tubercles 

 are visible except near the apex and the ridges are very distinct 

 and acute ; the general colour is not black, but bluish or violaceous. 

 In one of the specimens the thorax shows no trace of fulvous 

 except at the apex of the two frontal tubercles ; if looked at side- 

 ways, its elevated portion ends in a somewhat triangular ridge 

 posteriorly. 



Chlamts peruana, sp. n. 



Obsciu-e cupreous, the antennae and tarsi fulvous ; thorax with 

 the middle portion strongly raised, canaliculate at the top with 

 transverse ridges, sparingly punctured and finely strigose ; elytra 

 deeply and sparingly punctured, the suture entirely smooth, the 

 disc with some strong tubercles, notably two transverse ones at 

 the middle and four or five near the apex. 



Length 3 millim. 



Head with a longitudinal depression at the vertex, scarcely 

 punctured and finely strigose ; antennse pale fulvous, the last six 

 joints thickened but not very strongly transverse ; thorax with the 

 middle portion strongly raised into a round elevation, the middle of 

 which is canaliculate and bounded laterally at the postei'ior portion 

 by acute ridges (if viewed sideways), which extend downwards at 

 the sides in a kind of network, a slight callosity is also visible 

 between the elevation and the lateral margins, the interstices are 

 very sparingly punctured but finely strigose, the anterior margin is 

 also accompanied by a row of distinct punctures ; scutellum of usual 

 shape, strongly transverse ; elytra subquadrate, scarcely constricted 

 at the middle, each elytron with two short longitudinal ridges 

 (near the suture and at the middle), which are joined at the middle 

 in shape of a semicircle, forming strongly raised acute tubercles ; if 

 looked at sideways, another compressed ridge runs from the 

 middle to the apex, where it ends in three or four highly raised 

 tubercles, the interstices are strongly but remotely punctured and, 

 like the other parts, finely strigose ; the underside and legs very 

 obscure cupreous, the breast strongly punctured, the abdomen with 

 a tubercle or callosity at the sides, the pygidium with a deep sulcus
