METRIOPHILUS. 589 
from about the middle in the 2, and at the tip in the $. Prothorax transverse, constricted and 
narrowed in front, the sides rounded anteriorly; closely foveolato-punctate. Scutellum rather large, 
rounded, densely squamose. Elytra flattened anteriorly, with rows of oblong punctures, the interstices 
alutaceous, broad, almost flat on the disc, convex at the sides. Beneath very sparsely punctate. Legs 
short ; anterior femora sharply, the others feebly, dentate. 
Length 43-52, breadth 24-24 millim. (¢ 2.) 
Hab. Paxama, Bugaba (Champion). 
Three specimens. Near WM. horridulus, but with the prothorax foveolato-punctate, 
and the scutellum rather large and rounded. The very coarsely sculptured prothorax 
separates M. cribricollis from M. nigrescens and other species with opaque surface and 
black sete. 
12. Metriophilus nigrescens, sp. n. (Tab. XXIX. figg. 3, 3a.) 
Subovate, broad, opaque, black, the antenne ferruginous ; clothed above with small brownish scales intermixed 
with short, coarse, semierect, black sets, which are condensed into numerous, interrupted, sinuous, 
transverse lines on the elytra and into four small fascicles on the prothorax (two at the apex and two on 
the disc), the latter with a small fulvous spot on the median lobe, the scutellum similarly coloured, the 
vestiture of the under surface and legs dark brown. Head arcuately depressed in front, rugosely 
punctate ; rostrum stout, strongly curved, becoming gibbous basally, rugosely punctate at the sides and 
base, and for the rest smooth and shining, the antenne inserted at about the middle, joints 1 and 2 of 
the funiculus subequal in length, the club ovate. Prothorax strongly transverse, rounded at the sides 
anteriorly, much narrowed and constricted in front; closely, rather finely punctate, feebly binodose on 
the disc and also at the apex. Scutellum rounded, prominent. LElytra very much wider than the 
prothorax, flattened on the disc anteriorly, subparallel to near the middle; seriate-punctate, the 
interstices alutaceous, broad, and almost flat. Beneath sparsely punctate. Legs short, stout, rugose ; 
femora subclavate, the anterior pair sharply, the others more feebly, dentate. 
Length 53-64, breadth 3-34 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Four specimens, probably including both sexes. Distinguishable by the numerous, 
irregular, sinuous, interrupted lines of black sete on the elytra, the rather finely 
punctured, fasciculate prothorax, and the very opaque surface, above and beneath. 
13. Metriophilus ramosus, sp. n. 
Subovate, opaque, black, the antenne and the tarsi in part ferruginous; sparsely clothed with very minute 
cinereous or brownish scales intermixed with short, coarse, semierect, black sete, the latter clustered 
into scattered, irregularly reticulate lines on the head, prothorax, and elytra, the prothorax also 
bifasciculate on the disc and at the apex, and with a small fulvous spot on the median lobe; the 
vestiture of the legs black, variegated with cinereous, that of the under surface very sparse. Head 
rugosely punctate, arcuately depressed in front ; rostrum strongly curved, rugose and subcarinate at the 
base, for the rest shining and almost smooth. Prothorax strongly transverse, very abruptly narrowed in 
front, the sides angulate or subdentate behind the apical constriction; sparsely, unequally punctate, and 
feebly binodose on the dise and at the apex. Scutellum oval, convex, shining. LElytra very much wider 
than the prothorax, subparallel to near the middle, flattened on the disc anteriorly, the humeri obliquely 
truncated in front; seriate-punctate, the interstices alutaceous, rather broad, and almost flat. Beneath 
sparsely punctate. Legs short; femora subclavate, the anterior pair sharply, the others more feebly, 
dentate ; tibie narrowed and slightly hollowed on the outer edge towards the apex. 
Length 44-5, breadth 23-2} millim.
