the elytra with rows of narrow, oblong punctures separated by broad interstices, the 
vestiture very different, the legs more elongate. 
5. Metriophilus horridulus, sp.n. (Tab. XXVIII. fig. 31.) 
Oblong-ovate, subopaque, nigro-piceous or black, the antenna obscure ferruginous; sparsely clothed with 
small fulvous or greyish scales, which are somewhat fasciculate on the elytra and are often condensed 
into a small patch on the median lobe of the prothorax, and also thickly set with long, suberect sete. 
Head densely, rugulosely punctate, flattened above the widely separated eyes; rostrum strongly 
curved, stout, somewhat gibbous at the base, about as long as the prothorax, rugosely punctate and 
tricarinate, sparsely punctate and shining at the tip, the antenne inserted far beyond the middle in both 
sexes, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax transverse, rounded at the 
sides anteriorly, narrowed and constricted in front; coarsely, rugosely punctate. Scutellum minute. 
Elytra much wider than the prothorax, narrowing from about the middle, flattened on the disc 
anteriorly ; with rows of oblong, narrow, subquadrate punctures, the interstices alutaceous, almost flat 
on the disc, convex at the sides, broader than the punctures, the suture slightly raised. Beneath opaque, 
very sparsely punctate. Fifth ventral segment of the d with a semicircular ridge before the apex, that 
of the ° triangularly swollen in the middle at the tip. Legs short; femora acutely dentate, the tooth 
on the anterior pair rather long. 
Length 33-44, breadth 14-2, millim. (¢ 2.) 
Hab. Nicaraeva (Sailé), Chontales (Belt, Janson); Panama, Bugaba, David, 
Caldera, Volcan de Chiriqui, Tolé (Champion). 
A common insect in Chiriqui. Smaller than UM. fugazr, the surface duller above 
and beneath, the seriate punctures on the elytra not so coarse, narrower than the 
interstices. The sparser vestiture of the elytra (which does not hide the sculpture), 
the smaller scutellum, and the more strongly dentate femora, separate it from the 
Venezuelan M. lynx, Faust. The surface is slightly shining in some specimens, 
opaque in others. 
6. Metriophilus minimus, sp.n. (Tab. XXVIII. figg. 32, 32 a.) 
Oblong-ovate, opaque, nigro-piceous or black, the elytra sometimes mottled with rufo-piceous, the antenn 
and the tips of the tarsi ferruginous; sparsely clothed with rather coarse ochreous scales, with a few 
blackish scales intermixed, the latter condensed into three or four spots on the disc of the prothorax, and 
the ochreous scales subfasciculate on the elytra, especially towards the apex, the elytra also somewhat 
thickly set with semierect sete. Head rugulosely punctate, flattened and subfoveate above the widely 
separated eyes; rostrum stout, strongly curved, a little longer than the prothorax, rugosely punctate and 
feebly carinate, finely punctate at the tip, the antennz inserted far beyond the middle, joint 2 of the 
funiculus shorter than 1, the club ovate. Prothorax transverse, constricted and narrowed in front, 
closely punctate. Scutellum small, squamose. Elytra much wider than the prothorax, flattened on the 
disc anteriorly ; with rows of oblong, subquadrate punctures, the interstices alutaceous, narrow, convex, 
becoming subcostate towards the sides, the suture also a little raised. Beneath opaque, sparsely, rather 
coarsely punctate. Legs short; femora sharply dentate. 
Length 23-34, breadth 13-14 millim, 
Hab. Nicaracua, Chontales (Janson); Panama, Bugaba, Volcan de Chiriqui

Many specimens. Smaller and less elongate than M. horridulus; the prothorax
