or ocliraceous ; tlie elytial inivrkings consisting of two fasciae 

 on the disc, neither reaching the suture — the antemedian one 

 transverse and extending downward on the outer part of the 

 disc (in one specimen divided into two spots), the postmedian 

 one oblique and extending outward to near tlie margin, — a 

 spot on the shoulder (sometimes extending across the base), 

 and a small apical patch ; sparsely clotlied with decumbent 

 yellow hairs intermixed with numerous, very long, erect, 

 dark setae. Head rugosely punctate on each side of the 

 smooth median space; antennje witli joints 5-10 sublrian- 

 gular, slightly decreasing in length. Prothorax oblong- 

 cordate, narrower in ? , constricted and transversely depressed 

 before tlie base, longitudinally rugose, except along the 

 smooth median line, tiie setigerous marginal tubercles well 

 developed. Elytra moderately long, subparallel in their 

 basal half ; interruptedly striato-punctate, the punctures 

 becoming very tine towards the apex, the transverse post- 

 basal depression deep, the interstices almost smooth, flat on 

 the disc, uneven towards the sides. Penis-sheath of r? 

 curved and acuminate at the tip, two long filamentary pro- 

 cesses projecting from it beneath, each process dilated at the 

 apex and bearing a conspicuous seta. 



Length 3^-4i mm. ( c? ? .)

iSeven specimens, one somewhat immature. This species 

 seems to be very nearly related to, and a little smaller than, 

 P. decoratus, Keitt., from La Luzera, Colombia; but the 

 elytra in the latter are said to be irregularly punctate, and to 

 have two transverse fascia?, the suture, base, and apex ferru- 

 ginous. In the Brazilian insect the dark portions of the 

 elytra are condensed into a narrow sutural stripe, a post- 

 basal fascia, a common saddle-shaped mark at the middle, 

 and a large, common, oval, subapical patch. The a^deagus 

 is partly extruded in two of the males before me. 



4. Platamops quadrisignataSy sp. n. 

 Moderately elongate, rather convex, shining ; piceous or 

 obscure ferruginous, the basal joints and tip of the antennae, 

 the tarsi, and a large humeral patch on each elytron and an 

 indeterminate patch of variable extent on the disc towards 

 the apex (not reaching the suture), testaceous or rufescent ; 

 sparsely clothed with decumbent yellow hairs intermixed with 

 numerous, very long, erect, darker setae. Head rugosely 

 punctate on each side of the smooth median space; antennse 

 rather short, joints 5-10 subequal in length, 6-10 subtri- 

 angulai. Prothorax oblong-cordate, longitudinally rugose
