200 THE ENTOMOLOGIST. 



ChLAMYS FULVIMANA, Sp. n. 



Obscure feneous below ; the head, antennae, and the spotted legs 

 fulvous, above black ; thorax with a deeply divided basal elevation, 

 the sides finely and closely punctured, the elevation strigose ; elytra 

 with nine tubercles, closely and strongly punctured ; sides of the 

 breast and the abdomen fulvous. Length, 5 millim. 



Head finely punctured, fulvous, the vertex with a black central 

 spot ; antennae fulvous ; thorax finely and closely punctured, black, 

 the sides with an elongate blunt callosity, the base strongly raised 

 at each side, deeply divided above, and slightly carinate at the top 

 of each division, the latter rugosely strigose; elytra constricted at the 

 middle, strongly punctured, the anterior portion with five tubercles; 

 a large one at the middle of the base, three small ones placed tri- 

 angularly below the first tubercle, and one of strongly transverse shape 

 near the suture at the middle ; five more small tubercles are placed at 

 the posterior portion of the elytra, at which place the interstices are 

 more or less rugose or reticulate ; the suture is finely serrate ; pygidium 

 finely rugose, carinate at the middle ; sides of the breast, and to a less 

 extent of the abdomen, as well as the legs, fulvous ; the femora and 

 tibiae with an elongate black streak at the outer side ; abdomen obscure 

 aeneous, finely punctured, the breast more strongly so. 



Hab. Costa Eica. 



I only know a single specimen of this well-marked species, 

 which seems allied to C. knochi, Koll., but has a differently sculp- 

 tured thorax, and coloured under side and legs. (My collection.) 



Chlamys surinamensis, sp.n. 



Bright cupreous ; the labrum and antennte fulvous ; thorax entirely 

 covered with fine confluent reticulations, the basal portion raised, 

 sulcate at the top, the sides with a blunt tubercle ; elytra sparingly 

 punctured, with four acutely raised flexuose ridges at the outer disc, a 

 short oblique ridge below the scutellum, and one near the suture below 

 the middle. Length, 5 millim. 



Head entirely covered with confluent longitudinal reticulations, 

 cupreous, the epistome more finely and closely reticulate-rugose ; 

 labrum and antennae fulvous ; thorax with the posterior portion 

 elevated, the elevation divided by a short but broad and very deep 

 sulcus, the back of the raised portion suddenly perpendicularly de- 

 flexed, and limited by a transverse sulcus, the sides likewise raised into 

 a broad blunt tubercle, the entire surface closely confluently reticulate ; 

 scutellum smooth, bright cupreous, its apex bisinuate ; elytra broadly 

 subquadrate, slightly narrowed posteriorly, with the following highly 

 raised cupreous costffi or ridges : a short oblique one immediately 

 below the scutellum from below the base to the suture ; a second one 

 from the middle of the base to the middle of the elytra, where it forms 

 an acute angle, and is continued along the suture, or gradually ap- 

 proaching it towards the apex ; at the latter place it turns upwards, 

 and continues along the lateral margin in a flexuose line to the 

 shoulder ; a third ridge begins in front of the shoulder, and, after 

 joining the second one at the middle, accompanies it for some distance,
