DESCRIPTIONS OF SOME NEW SPECIES OF 

 CHLAMYD^ FEOM SOUTH AMERICA. 



By Martin Jacoby. 



Chlamys trimaculata, sp. n. 



Flavous ; the bead and thorax spotted with purplish or black, 

 posterior portion of the latter moderately raised, the elevation undivided ; 

 elytra with a single tubercle at the base, the latter, three spots at the 

 middle, and the apex, deep purplish, the rest flavous, with brown punc- 

 tures, the middle and sides with some short ridges. Length, 4 millim. 



Head closely rugose-punctate, flavous, the middle with a more or 

 less distinctly marked dark purpUsh band ; antennae fulvous, the ter- 

 miual joints rather darker ; thorax with the basal portion gradually 

 raised into a rounded elevation, the back of which is bounded by a 

 serrate ridge and perpendicularly deflexed, the entire surface is covered 

 with small rugosities and reticulations, more or less of flavous coloura- 

 tion, the back of the elevation dark purplish to a greater or smaller 

 degree, the anterior portion stained with some small purplish spots, 

 placed transversely ; elytra subquadrate, with a single conical tubercle 

 at the middle of the basal margin, followed by an oblique ridge towards 

 the suture, which below the middle runs parallel with the suture to 

 some distance from the apex, another shorter ridge is placed still 

 closer to the suture anteriorly, and joins the other one near the 

 middle ;. smaller ridges occupy the posterior portion of the elytra at 

 the sides ; the latter are rather deeply sulcate below the shoulders, the 

 basal and apical portion are reddish brown, as well as three elongate 

 spots at the middle ; of these two are placed near the suture, one below 

 the other, and the third (the largest) at the side of them ; the rest of 

 the surface is pale yellowish, marked with dark brown punctures ; 

 pygidium, under side, and legs flavous, closely reticulate. 



Hah. Jatahy, Prov. Goyaz, Brazil. 



At first sight this species seems identical with C. reticulata, 

 Klug, but in that species the thorax has two broad purplish 

 bands, and another one at each side, and the elytra are provided 

 with another tubercle near the suture at the middle, and a third 

 near the apex, of which there is no trace in the two specimens of
