590 RHYNCHOPHORA. 
Hab. Guatemata, Las Mercedes, Cerro Zunil, Zapote (Champion). 
Four specimens, all from the Pacific slope. Smaller and narrower than I, nigrescens ; 
the prothorax angulate or dentate, and also subfasciculate, at the sides before the 
middle, very abruptly narrowed in front, and sparsely, unequally punctate; the 
scutellum small, &c. The black sete on the anterior portion of the elytra are 
condensed on each side of the scutellum into an oblique line, which extends forwards 
to the base. 
14. Metriophilus ramulosus, sp. n. (Lab. XXIX. figg. 4, 44.) 
Oblong, opaque, black, the antennw and tarsi ferruginous ; sparsely clothed with very minute brownish scales 
intermixed with short, coarse, black sets, the latter condensed into six fascicles on the prothorax (four 
in a transverse series across the middle and two at the apex) and various short, dense, oblique, irregular 
lines on the elytra, the prothorax with a fulvous spot on the median lobe; the vestiture of the head, 
legs, and under surface brown and cinereous intermixed. Head rugosely punctate, arcuately depressed 
in front; rostrum as in M. ramosus. Prothorax strongly transverse, abruptly narrowed and strongly 
constricted in front, binodose at the apex and quadrinodose across the middle ; closely, equally punctate 
and faintly canaliculate. Scutellum small, oblong, dull, and squamulose. Elytra much wider than the 
prothorax, subparallel in their basal half, flattened on the disc anteriorly ; seriate-punctate, the inter- 
stices alutaceous, rather broad, almost flat. Beneath sparsely punctate. Legs short; femora subclavate, 
the anterior pair sharply, the others more feebly, dentate. 
Length 4, breadth 2 millim. 
Hab. Panama, Bugaba (Champion). 
One specimen. Narrower than Jf. ramosus; the prothorax closely, uniformly 
punctate, with four isolated fascicles of black sete placed transversely across the disc, 
as well as two others at the apex, the sides not dentate ; the black lines on the elytra 
not reaching the base. An allied form occurs in Brazil (Cryptorhynchus piligerus, 
Jekel, in litt.). 
15. Metriophilus nigrisetis, sp. n. 
Subovate, opaque, black, the antenne and tarsi ferruginous ; sparsely clothed with intermixed minute cinereous 
and larger brown scales, the prothorax and elytra fasciculate with suberect, black, setiform scales, the 
prothorax sometimes with a fulvous spot in the middle at the base; the vestiture of the legs blackish, 
mottled with cinereous. Head transversely flattened in front, rugosely punctate, the eyes widely 
separated ; rostrum stout, strongly curved, rugosely punctate and feebly carinate, smooth along the 
middle in its apical half, shining and more sparsely punctate in the 2, the antenne inserted at about 
midway, joint 2 of the funiculus shorter than 1, the club ovate. Prothorax strongly transverse, abruptly 
narrowed and constricted in front, and also narrowed behind; rugulosely punctate. Scutellum small. 
Elytra short, widest about the middle, much broader than the prothorax, the humeri not prominent ; 
seriate-punctate, the interstices rather broad, alutaceous, almost flat. Beneath rather coarsely punctate. 
Legs short ; anterior femora rather sharply, the others feebly, dentate. 
Length 34-4, breadth 14-23 millim. (d 2.) 
Hab. Muxico, Juquila (Sallé), Chilpancingo (Z/. H. Snvith); Guatemata, Calderas 
(Champion). 
Three specimens, one of the two males having the rostrum much shorter than the
