228 RHYNCHOPHORA. 
interstices almost flat and asperato-punctate. Legs short, the femora each with a small sharp tooth, 
the tarsal claws with a sharp tooth. 
Length 23,, breadth 13 millim. (2.) 
Hab. Guaremata, Cahabon in Vera Paz (Champion). 
One specimen, slightly abraded. Broader and much more robust than P. scutellaris, 
the rostrum very broad, the femora acutely toothed, the tarsal claws with a sharp 
tooth, the elytral interstices wider and less convex. The elytra, as in that species, 
have an angulated transverse fascia before the middle, which is dilated into an 
- irregular ring on the disc.

Piazorhinus scutellaris, Gyll. in Schénh. Gen. Cure. iii. p. 4727; Lec. Proc. Am. Phil. Soe. xv. 
p- 210°. 
Subovate, the head and prothorax dull, the elytra shining; black, the elytra with a brassy lustre, the antenne 
and tarsi rufo-testaceous, the antennal club sometimes infuscate ; sparsely clothed with grey or yellowish 
pubescence, which on the elytra is mainly concentrated into two narrow transverse fascise—the one 
before middle strongly angulate and sending off a branch to the scutellum, the other straighter and 
placed at about one-third from the apex,—the vestiture of the scutellum, under surface, and legs white. 
Head sparsely punctate, the eyes comparatively small and somewhat widely separated ; rostrum stout, 
very short, and rugulosely punctate in the g, longer and with the apex nearly smooth in the 9; antenne 
short, the club ovate. Prothorax transverse, subconical, closely punctate, sometimes with a short median 
carina. Elytra much wider than the prothorax, subparallel in their basal half, the humeri a little 
swollen ; deeply punctate-striate, the interstices convex and roughly punctulate. Legs comparatively 
slender, the femora each with an excessively minute tooth. 
Length 12-14, breadth 1-15 millim. (¢ @.) 
Hab. Nortu America! 2, Atlantic States 3.—Mexico, Omilteme in Guerrero (H. H. 
Smith); GuatemaLa, San Juan and San Gerdnimo in Vera Paz (Champion); Panama, 
Volcan de Chiriqui (Champion). 
Eizht specimens, differing from North-American examples of P. scutellaris in having 
the pubescence a little shorter and the elytral fascie somewhat narrower. Extremely 
like P. cingulatus, but with the eyes much smaller, the elytral pubescence differently 
arranged, and the legs more slender, the femoral tooth being very minute. 
12. Piazorrhinus cingulatus, sp.n. (Tab. XII. fig. 30.) 
Subovate, the head and prothorax dull, the elytra shining; black, the elytra with a brassy or violaceous lustre, 
the rostrum reddish at the tip, the antennse and tarsi ferruginous or rufo-testaceous, the antennal club 
sometimes darker ; sparsely clothed with a grey or yellowish pubescence, which on the elytra is concen- 
trated into an irregular patch behind the scutellum and a common, curved fascia (extending outwards to 
beneath the humeri) at the middle of the disc, the vestiture of the seutellum, under surface, and legs 
white. Head sparsely punctate, the eyes very large and narrowly separated ; rostrum very short and 
stout in the d, longer in the 9, widening outwards, thickly punctate, in the 2 feebly carinate at the 
base and almost smooth at the tip; antenne short, the club ovate. Prothorax broader than long, 
slightly rounded at the sides, subconical, closely punctate, and sometimes with a short median carina, 
Elytra much wider than the prothorax, subparailel in their basal half, the humeri broadly rounded ;
