508 SOUTH AMERICAN HALTICIDAE (cOLEOPTERA) 



hair, the yellow markings and pubescence are like lateralis; body beneath 

 shining black, the anterior legs are yellow with the upper side of the apical 

 half of the femora and apex of tibiae and tarsi black, hind legs yellow with 

 the apex of femora particularly on top and the tarsi black, claws appendiculate. 



Near lateralis but much smaller with different colored legs. 

 Three examples bear the type data, also one probably from 

 same place in Second Jac. coll. marked "n.i.m." 



Metriotes sericeus nov. sp. 



Elongate black, elytra punctate striate black, with a narrow 

 sub-border stripe of yellow color, the entire surface thickly cov- 

 ered with very short appressed grayish yellow pubescence, so 

 thick as nearly to obscure all the markings. 



Type. — Peru. Square green label. (Callanga?) Second Jac. 

 coll. "n.i.m." Length 5.5 mm. 



Clypeus with usual side carinae which are blunt and form at their junction 

 a smooth knob or tubercle between the antennae and ending in a deep longitu- 

 dinal frontal fovea with high side walls making two frontal tubercles, vertex and 

 neck punctulate; antennae filiform, black, reaching the middle of the elji^ra; 

 thorax transverse, sides margined, straight, all the angles prominent, two 

 oblique side basal depressions giving prominence to the middle which is rather 

 shiny, the rest of the surface opaque with black pubescence; the scutellum and 

 elytra present an unbroken surface of sericeous pubescence, under which the 

 markings are but faintly made out; body beneath and legs shining black, 

 outside edge of hind tibiae serrate, claws appendiculate. 



With the type I associate an example from (ochabamba^ 

 Bolivia, (Germ.). 



Metriotes marginatus iiov. sp. 



Elongate, black, clypeus, thorax and small antehumeral spot 

 rufous, elytra strongly punctate striate, with very short ashy 

 pubescence, which is thickened so as to show a narrow distinct 

 sutural edge and a wide sublateral stripe to the apex. 



Type. — Cochabamba, Bolivia. (Germ.) Length 4.5 mm. 



Clypeus smooth with the usual carinae rather obsolete, the usual frontal 

 fovea makes two rather prominent knobs, limited behind by an obsolete trans- 

 verse depression, vertex and neck punctulate; antennae fihform, black, reach- 

 ing below the middle of the elytra; thorax transverse, sides margined, straight, 

 all the angles prominent, an obsolete transverse basal and side oblique depres- 

 sion brings the disk into prominence, the surface finely pubescent; elytra witli 

 a very obsolete basal depression, the small rufous spot adjoins the thorax and 

 just touches the humeral knob; body beneath and legs black, somewhat pu-
