P. {Spitliohates) macnlatus, Clianiit. Tlie types of P. deco- 

 ratus and P. viltatus, Keitt., are, 1 believe, in the Oberthiir 

 collection at llennes. The ei^ht species may be tabulated 

 thus :— 



Antenna? widened from fifth joint. 



KyeB larger ; elytra immaculate .... svtosus, Champ. [Panama.] 

 Eves smaller; elytra maculate. 



I'rothora\ smooth at base ; elytra 



bimaculate binotatus, sp. n. [Colombia,] 



Protborax closely punctate to base. 

 Elytra strongly attenuate poste- 

 riorly, fusco-bicruciate .... Mephanoidea, sp. n. [Brazil.] 

 Elyfra less attenuate poste- 

 riorly. 

 Elytra transversely bifasciate, 



irregularly punctate .... decoratus, sp. n. [Colombia.] 

 Elytra obliquely bifasciate, 



striato-punctate obliquu.<<, sp. n. [Brazil.] 



Elytra quadrimaculate 4-sipiatus, sp, n. [Brazil.] 



Elytra vittate vittatus, 'Reitt. [Colombia.] 



AntennsB widened from ninth joint ; (America, 



elytra spotted macvlatux, Champ, [Central 



1. Platamops binotatus, sp. n. 



Elongate, attenuate posteriorly, shining ; niftro-piceous, 

 the head in front, the ba.'jal joints and tip of the antennse, 

 the Hanks ot the j^rothorax, and a large patch on each elytron 

 below the humeri, rufous or tenuginous, the tarsi testaceous, 

 the femora and tibise darker ; very sparsely clothed with 

 decumbent yellow hairs intermixed with very long, erect, 

 scattered setae. Head rugosely punctate on each side of the 

 smooth median space, the eyes rather small, prominent ; 

 antennte long, joints 5-10 subequal, longer than broad. 

 Protborax convex, oblong-cordate, strongly constricted and 

 transversely sulcata before the base ; sparsely, coarsely, 

 separately punctate on each side of tlie rather broad smooth 

 median space, the constricted basal portion almost inipunctate, 

 the five setigerous marginal tubercles small. Elytra mode- 

 rately elongate, broad, gradually widened to the middle and 

 rapidly narrowed thence to the apex, the transverse j)Ost- 

 basal depression deep ; sparsely, rather coarsely punctate, 

 the punctures becotning very small from the middle onward.'^, 

 and showing a faint trace of a linear arrangement on the 

 disc, the postmedian sutural depression rather deep, the 

 interstices smooth, flat on the disc, uneven towards the sides 

 and apex. Intermediate and posterior tarsi very elongate, 

 much longer than the anterior pair.
