848 THK LATE MR. M. JACOBY OX NEW [Nov. 26, 



black, rest black, basal joint black above, third joint much shorter 

 than fourth. Thoi'ax about one and a half times broader than 

 long, sides subangulately rovmded near base, but slightly narrowed 

 in fi'ont; ; sui-face with a rather deep oblique impression near base 

 at each side, strongly and rather closely punctured, black, some 

 narrow, irregulai*, short stripes at the extreme lateral margins 

 pale yellow, basal margin not produced at middle. Scutellum 

 broader than long. Elytra about one-half longer than thorax, 

 very strongly punctate-striate, extreme apex nearly smooth ; a 

 regular subquadrate dark red spot is placed at the shoulders, 

 extending inwards as far as the third row of punctures and down- 

 wards nearly to the middle of the elytra. Under side black, 

 covered with rather long white pubescence ; legs black ; femoi'a 

 all margined with yellow below. 



Uah. Brazil. 



I possess only a single apparently female specimen of this 

 species, which may be known from other somewhat similarly 

 marked by the strong puncturation of the head and upper parts 

 and the regular, nearly squai'e-shaped elytra! patch, as well as the 

 colour of the femoi'a. 



Metallactus bolivianus, sp. n. 



Below black ; head obscure fulvous, with a, central white patch ; 

 thorax short, spai-ingly punctured, yellowish w^hite, with a large 

 subquadrate black patch at each side ; elytra finely punctate- 

 striate, pale yellowish, a transverse band at the base, another 

 below the middle, and the sutural and apical margins black. 



Length 4 millim. 



Head flat, the inner margins of the eyes, the intermediate 

 space, and the clypeus distinctly punctured, the latter and the 

 vertex obscure fulvous, intraocular space yellowish white ; eyes 

 w^ell separated, subquadrately emarginate, this space strongly 

 punctured ; antennse with the lower five joints black (the rest 

 wanting), third joint slightly shorter than the foui'th. Thorax 

 twice as broad as long, of equal width, not narrowed anteriorly, 

 the sides feebly rounded anteriorly, the base with a short but 

 deep sulcus at each side ; surface very remotely punctured at the 

 disc, the sides rather more closely and strongly so ; the ground- 

 colour yellowish white, the sides w^ith a large subquadrate black 

 patch, more closely approached to the anterior than the posterior 

 margin, its lower edge oblique. Scutellum broader than long, finely 

 punctured, black, its apex truncate. Elytra paxallel-sided, rather 

 strongly punctate-sti'iate, the punctured rows closely approached 

 and rather irregular at the base, more widely separated pos- 

 teriorly, of the same colour as the thorax, the base with a 

 transverse narrow black band not extending to the lateral 

 margins; a similar band is placed below the middle, extending 

 to the extreme lateral and apical margins, the latter therefore 

 including a round flavous spot at the apex of each elytron. 

 Under side and legs black, sides of the abdominal segments flavous.
