partly geminate ; puncturation from middle downwards more 

 regular and in single rows, last two rows more distinct ; interstices 

 flat. Presternum longer than broad, deeply concave anteriorly. 



Hah. Brazil. 



Of entirely fulvous colour ; the puncturation of thorax very 

 remote, that of the elyti^a iri-egular at base. I received a speci- 

 men from Mr. C. Bruch at the La Plata Museum without a more 

 detailed locality. 



Metallactus donckieri, sp. n. 



Yellowish white ; thorax sparingly punctured, disc with a black 

 triangular spot ; elytra closely punctate-striate, a transverse band 

 at the base and another at the apex black. 



Yar, Elytra with two spots at base and one below middle 

 black. 



Length 3| millim. 



Head with central longitudinal groove, nearly impunctate at 

 vertex, the latter sometimes with a triangular black spot ; lower 

 portion of the clypeus and the labrum brownish ; lower four joints 

 of antennae more or less pale below, following three black, rest 

 w^anting, third and fourth joints equal. Thorax twice as broad as 

 long or somewhat broader, sides nearly straight, base with a deep 

 oblique depression at each side ; surface sparingly impressed with 

 deep punctures at disc and sides, the middle with a triangular 

 black spot or fulvous band, sides with another more obscure mark. 

 Elytra with closely placed rows of deep punctures of transverse 

 shape, those near the suture more confusedly arranged, the 

 punctures partly absent at the middle between the 6th and 8th 

 rows ; interstices slightly convex. Pygidium, under side, and legs 

 yellowish white ; presternum slightly longer than broad. 



Hah. Jalahy, Prov. Goyaz, Brazil. 



I have taken the banded form as that of the type, but between 

 this and the spotted varieties probably other variations occur. 

 The species seems almost identical with some of the varieties of 

 M. nigro-omat%is Stal, but may be at once distinguished by the 

 pale under side and legs, and by the interrupted punctures at the 

 sides of the elytra,. 



Metallactus partitus, sp. n. 



Head, breast, and middle cf the abdomen black ; clypeus flavous ; 

 thorax fulvous, with an anterior black spot, closely punctured ; 

 elytra finely punctate-striate, black, a transverse band at the 

 middle fvdvous. 



Length 3| millim. 



Head sparingly punctured at vertex, the latter black, lower 

 portion pale fulvous, strongly punctured ; anterior edge of clypeus 

 black, labrum pale fulvous ; eyes closely approached at middle, 

 very large, their emargination small and triangular; antennae 

 extending to middle of elytra, black, lower five joints fulvous, 

 third joint slightly shorter than fourth, basal joint black above. 

 Thorax about one-half broader than long, sides obliquely but
