224 RHYNCHOPHORA. 
1. Piazorrhinus cionoides, sp.n. (Tab. XII. figg. 22, 22 a.) 
Broad-ovate, very convex, shining, black, with a brassy or violaceous lustre, the rostrum, antenne, legs, and 
abdomen testaceous or rufo-testaceous; thickly clothed with long, adpressed, greyish-white pubescence, 
the elytra with a large, common, transverse, rounded space on the disc before the middle almost bare. 
Head closely punctate, the eyes very large and somewhat narrowly separated; rostrum very stout, 
flattened, much widened outwards, about as long as the prothorax, punctured at the sides, carinate at 
the base, the carina flattened, smooth, and widening forwards; antenne short, the club stout and ovate. 
Prothorax much broader than long, very wide at the base, rapidly narrowing forwards, closely punctate. 
Elytra gibbous, broad, the shoulders not prominent, obliquely truncated in front almost in a line with 
the sides of the prothorax (as seen from above); deeply punctate-striate, the interstices convex and 
thickly punctulate. Legs rather stout, the intermediate and posterior femora each with an extremely 
minute tooth. . 
Length 33-32, breadth 23-33 millim. (2.) 
Hab. Mexico, Playa Vicente (Sallé), Atoyac (H. H. Smith); Guatemata, Las 
Mercedes, Pacific slope (Champion). 
A very curious species, with the general facies of a Cionus, and also not unlike 
certain American Coccinellids of the genera Poria and Azya, except that it has only 
one large bare space on the disc of the elytra. ‘The anterior femora are unarmed, and 
the tooth on each of the other pairs is very minute. Three specimens. 
®, Piazorrhinus rufipes, sp.n. (Tab. XII. fig. 23.) 
Subovate, shining, nigro-piceous, the apical half of the rostrum, the antenna, legs, and pygidium ferruginous, 
the femora sometimes blackish at the middle; the head and prothorax clothed with ochreous, and the 
sides and apex of the elytra broadly, the propleura, legs, and under surface with white, pubescence, 
the scutellum with yellowish hairs, the rest of the elytra almost bare. Head closely, somewhat coarsely 
punctate, the eyes very large and well separated ; rostrum very stout, widening outwards, in the ¢ quite 
short, in the 9 about as long as the prothorax, coarsely, closely punctate, the apical portion smooth ; 
antenne rather long, the club elongate-ovate, acuminate, about equalling joints 2-7 of the funiculus 
united. Prothorax transverse, conical, closely, somewhat coarsely punctate, the disc with a smooth, 
abbreviated, median carina. Elytra much wider than the prothorax, convex, subparallel at the base, the 
humeri a little swollen ; deeply punctate-striate, the interstices narrow, convex, and punctulate. Legs 
rather long, the femora unarmed. 
Length 23-23, breadth 13 millim. (d¢ 2.) 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
Easily recognizable by the unarmed femora, the comparatively long antenne, and 
the peculiar colour and arrangement of the pubescence on the upper surface. The 
elytra have a broad space at the sides and apex clothed with rather long, adpressed, 
white hairs, and the rest of their surface is almost bare. ‘The pubescence of the 
prothorax is golden or fulvous on the disc, becoming white at the sides. Two females 
and one male. 
3. Piazorrhinus inermis, sp.n. (Tab. XII. figg. 24, 24a.) 
Subovate, shining, ferruginous, a little darker beneath, the elytra with a common, V-shaped, blackish patch 
at the middle; above somewhat sparsely clothed with ochreous pubescence, the dark elytral marking 
bare, the under surface and legs with white hairs. Head closely, somewhat coarsely punctate, the eyes
