METRIOPHILUS. 587 
less setose and variegated with rather coarse scales, the scutellum rounded and 
Squamose ; the elytral interstices convex throughout. I have not detected any 
sexual differences. 
7. Metriophilus nitidus, sp. n. 
Oblong-ovate, shining, piceous, the antenne and the tips of the tarsi ferruginous; the head and prothorax 
sparsely, and the elytra more thickly, clothed with fulvous scales intermixed with rather long, similarly- 
coloured, semierect set ; the vestiture of the under surface very sparse, that of the legs more abundant 
and setiform. Head rugulosely punctate, slightly flattened above the widely separated eyes ; rostrum 
strongly curved, rugulose at the base and very sparsely, finely punctate thence to the tip, the antenne 
inserted at a little beyond the middle, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax 
transverse, narrowed and feebly constricted in front; coarsely rugosely punctate. Scutellum small, 
depressed. Elytra much wider than the prothorax, narrowing from the middle; with rows of coarse 
subquadrate punctures, the interstices narrow, punctulate or rugulose, flat on the disc, convex at the sides, 
Beneath coarsely, somewhat closely punctate; fifth ventral segment foveate, the fovea almost enclosed 
by a v-shaped prominence. Legs rather short; anterior femora somewhat sharply dentate, the others 
obsoletely dentate or unarmed. 
Length 33-45, breadth 13-2 millim. (¢.) 
Hab. Panama, Bugaba (Champion). 
Two males. Smaller than MW. fugax, the vestiture uniformly coloured, the femora 
more feebly dentate, the fifth ventral segment of the male with a V-shaped 
prominence. 
8. Metriophilus occultus, sp. n. 
Oblong-ovate, opaque, black, the antenne ferruginous; the prothorax clothed with short, fulvous and 
blackish, setiform scales ; the scutellum whitish or ochreous ; the elytra somewhat thickly clothed with 
fulvous scales, with a few intermixed darker scales on the apical declivity, the interstices each with a 
row of semierect sete; the legs thickly, and the under surface very sparsely, clothed with narrow 
fulvous and cinereous scales. Head rugulosely punctate, transversely depressed in front, the vertex 
shining and more sparsely punctured; rostrum strongly curved, somewhat gibbous at the base, rugulose 
and subcarinate, sparsely punctate and shining at the tip, the antenne inserted at a little beyond the 
middle, joint 2 of the funiculus shorter than 1. Prothorax transverse, rounded at the sides anteriorly, 
narrowed and constricted in front ; coarsely, rugosely punctate. Scutellum small, rounded, squamose. 
Elytra much wider than the prothorax, flattened anteriorly; with rows of narrow, subquadrate 
punctures, the interstices alutaceous, rather broad, flat on the disc, convex at the sides, the suture 
cariniform. Beneath very sparsely punctate ; fifth ventral segment with an indistinct transverse curved 
ridge in the middle at the apex in the g. Legs short; femora foebly dentate. 
Length 33-4, breadth 13-2 millim. (¢ 2.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Three specimens. Very like M. horridulus, but with the vertex of the head 
shining and rather sparsely punctate, the scutellum squamose and more promi- 
nent, the vestiture of the elytra fulvous, with intermixed darker scales on the 
apical declivity. Compared with M. tenuipes, Faust, it is less elongate, and has 
a stouter rostrum, &c. ‘The head and rostrum are sometimes feebly carinate.
