PIAZORRHINUS. 225 
very large, convex, rounded, and well separated; rostrum very short and stout, widening outwards, 
coarsely, closely punctate, smooth at the tip; antenne rather long, the club elongate-ovate, acuminate, 
a little shorter than the funiculus. Prothorax transverse, subconical, slightly constricted in front, 
coarsely, closely 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. Femora unarmed. 
Length 23, breadth 14 millim. (<¢.) 
Hab. Guatemaa, San Gerénimo (Champion). 
Very closely allied to P. rufipes, but ferruginous in colour, the elytra with a 
common, V-shaped, bare, blackish patch at the middle, the antenne a little longer, 
the eyes more convex, the prothorax more coarsely punctured; the vestiture of the 
upper surface is yellowish, the elytra having a very large triangular patch at the base, 
as well as the sides and apex, pubescent. One specimen. 
4, Piazorrhinus uniformis, sp. n. 
Subovate, shining, black, the apical half of the rostrum, the antennz, and legs ferruginous ; somewhat sparsely 
and uniformly clothed with whitish pubescence, which is seriately arranged on the elytra (there being a 
single row of hairs on each of the strive and interstices), the vestiture of the scutellum dense and white. 
Head sparsely punctate, rugose between the eyes, which are very large and narrowly separated ; rostrum 
very stout, widening outwards, shorter than the prothorax, rugose at the base, smooth at the tip; 
antenne short, the club acuminate and about as long as the funiculus. Prothorax much broader than 
long, somewhat rounded at the sides, narrowing almost from the base, feebly constricted in front, closely 
punctate, the disc obsoletely carinate posteriorly. Elytra much wider than the prothorax, convex, 
subparallel in their anterior third, the humeri rounded and not prominent; deeply punctate-striate, the 
interstices narrow, convex, and roughly punctulate. Legs short, the femora unarmed. 
Length 13, breadth 1 milim. (@.) 
Hab. Panama, Tolé (Champion). 
One specimen. The uniform, seriately arranged pubescence, the short, ferruginous 
legs, and unarmed femora, separate this small species at once from its allies. 
5. Piazorrhinus albofasciatus, sp.n. (Tab. XII. figg. 25, 25 a.) 
Subovate, rather broad, shining, black, faintly mottled with ferruginous (or obscure ferruginous, with the 
prothorax and elytra mottled with black), the antenne ferruginous, the legs wholly or partly of that 
colour; the elytra with angulated fascia of ochreous and white hairs, the pubescence on the prothorax in 
great part ochreous, and that on the under surface and legs white. Head closely punctate, the eyes 
very large and well separated; rostrum very short and stout, slightly longer in the 2, widening 
outwards, somewhat coarsely punctate, almost smooth at the tip; antenne short, the club ovate and 
compact. Prothorax transverse, subconical, feebly constricted in front, closely punctate, more or less 
gibbous and carinate at the middle of the disc. Elytra much wider than the prothorax, convex, 
subparallel in their basal half, subtruncate at the apex, the humeri a little swollen; deeply punctate- 
striate, the interstices narrow, convex, and punctulate. Legs short and stout, the femora each with an 
acute tooth, that on the hind pair small. 
Length 2-24, breadth 14-14 millim. (¢ Q.) 
Hab. Guatemata, Coban, San Isidro (Champion). 
Distinguishable by the oblong prominence on the disc of the prothorax (this being 
very conspicuous in the San Gerénimo insect), the angulate ochreous and white fasciz
