of the Genus ^laiamops. 471 



P. {SpitJiohates) maculatus, Champ. The types of P. deco- 

 ratus and P. viitatus, Keitt., are, I believe, in the Oberthiir 

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

 thus : — 



Antennae widened from fifth joint. 



Eyes larger ; elytra immaculate .... setosiis, Champ. [Panama.] 

 Eyes smaller ; elytra maculate. 



Prothorax smooth at base ; elytra 



bimaculate binotatus, sj). u. [Colombia.] 



Protborax closely punctate to base. 

 Elytra strongly attenuate poste- 



rioi'ly, fusco-bicruciate .... telephanoides, sp. n. [Brazil.] 

 Elytra less attenuate poste- 

 riorly. 

 Elytra transversely bifasciate, 



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

 Elytra obliquely bifasciate, 



striato-punctate obliquus, sp. n. [Brazil.] 



Elytra quadrimaculate i-signatus, sp. n. [Brazil.] 



Elytra vittate vittatiis, Reitt. [Colombia.] 



Antennte widened from ninth joint ; (America, 



elytra spotted maculatus, Cbamp. [Central 



1. Platamops binotatus, sp. n. 



Elongate, attenuate posteriori}', shining ; ni<;ro-piceous, 

 tlie head in front, the basal joints and tip of the antennaj, 

 the Hanks oi the prothorax, and a large patch on each elytron 

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

 the femora and tibia? 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 ; 

 antenna? long, joints 5-10 subequal, longer than broad. 

 Prothorax convex, oblong-cordate, strongly constricted and 

 transversely sulcata before the base; sparsely, coarsely, 

 separately punctate on each side of the rather broad smooth 

 median space, the constiicted basal portion almost impunctate, 

 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 post- 

 basal depression deep ; sparsely, rather coarsely punctate, 

 the punctures becoming very small from the middle onwards, 

 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 })osterior tarsi very elongate, 

 much longer than the anterior pair.
