8.'J2 THE LATE MR. M. .TACOBY ON XEW [Nov. 26, 



tudinally strigate and finely pubescent. Elyti^a with deep and 

 irregular rows of punctures, those near the suture still more 

 confusedly placed ; all rows distinct except at the extreme apex, 

 the latter with a round fulvous spot not extending to either 

 margin ; another narrow elongate spot is placed in front of the 

 shoulders, extending nearly to the middle of the lateral margins 

 but not to the humei-al callus. Body below finely pubescent, 

 black; legs purplish black, extreme base of the femora fulvous. 

 Prosternum. broaxl, subquadrate, finely punctured and pubescent, 

 surface slightly concave. 



Hah. Brazil. 



The entirely purplish ground-colour, strong elytral punctura- 

 tion, and the shape of the elytral markings distinguish this species, 

 of which I received a specimen from Mr. 0. Bruch, of the 

 La Plata Museum, without detailed locality. M. palcumon ^u.^. 

 and allied species all differ in their black colour and diii'erent 

 markings. 



Mbtallactus peruanus, sp. n. 



Flavous ; vertex with a black spot ; thorax and elytra black, 

 the last-named with four raised spots placed subquadrately at 

 suture, two other spots at apex and the pygidium white. 



Length 4 millim. 



Head with a few punctures at vertex, the latter with a trian- 

 gular black spot at base, middle with a longitudinal groove, 

 entire sides occupied by the large oblique eyes, which closely 

 approach at top, their emai-gination very broad and subtriangular, 

 their surface spotted with black ; lower portion of face im- 

 punctate ; base of antennae with a brownish spot, lower six 

 joints piceous, more or less pale at base, rest broken off, third 

 joint shorter than fourth. Thorax about one-half broader than 

 long, narrowed anteriorly, the sides and middle with patches of 

 irregularly placed distinct punctures, forming a W-shaped band, 

 rest of surface impunctate, black. Scutellum obscure fulvous, 

 truncate at apex. Elytra with fine, partly geminate rows of 

 punctures at the black portions only, the white spots impunctate, 

 raised, those near the scutellum raised to a point at the apex of 

 the latter ; the black portion at the sides likewise convex and 

 smooth, surrounded by a few rows of punctures ; each elytron 

 with three large round white patches, one at base near the 

 scutellum, followed immediately by a, similar patch at the suture, 

 and the third rather smaller at the apical angle ; besides these 

 markings, a short elongate spot somewhat obscure is placed near 

 the lateral margins at the apex. Pj^gidium, under side, and legs 

 yellowish white ; prosternum twice as long as broad. 



Hah. Peru. 



This is one of the most peculiarly marked and sculptured species 

 of the genus, and much distinguished by the raised black and 

 white elytral spaces devoid of punctures and the elytral markings. 

 I have only a single specimen.
