irregular spots along the suture black. The male has the first ventral segment 
hollowed down the centre, and the fifth transversely depressed in the middle towards 
the apex. The femora are strongly dentate, the tooth on the anterior pair long.

Oblong-ovate, opaque, black, the antenne and the tips of the tarsi ferruginous; the prothorax somewhat 
thickly clothed with blackish setiform scales, which are clustered into two fascicles at the apex, and 
with three short fulvous streaks at the base; the elytra densely clothed with intermixed fulvous and 
cinereous scales, and with a rather broad space at the apex (extending forwards at the sides) sparsely 
clothed with blackish scales, with a few cinereous scales intermixed, the interstices each with a row of 
rather coarse semierect sete; the under surface and legs very sparsely clothed with narrow brownish 
and cinereous scales. Head transversely depressed and sparsely, coarsely punctate above the widely 
separated eyes, the vertex densely, finely punctate ; rostrum strongly curved, a little longer than the 
prothorax, rugosely punctate and carinate at the base, the apical half sparsely finely punctate, the 
antenne inserted slightly beyond the middle, joint 2 of the funiculus shorter than 1, the club ovate. 
Prothorax transverse, narrowed and feebly constricted in front; closely, coarsely punctate. Scutellum 
small, convex. Elytra much wider than the prothorax, flattened on the disc; with rows of narrow, 
oblong punctures, the interstices alutaceous, rather broad, flattened on the disc, convex at the sides and 
apex, the suture cariniform. Beneath opaque, sparsely coarsely punctate. Ventral segmonts 1 and 2 
connate at the middle. Legs short; femora dentate, the tooth on the anterior pair long. 
Length 43-5, breadth 2-22 millim. 
Hab. Mexico, Jalapa (Hoge), Teapa (H. H. Smith). 
Four specimens. Narrower and more depressed than JM. definitus, the black apical 
patch extending forwards at the sides, the head with a transverse depressed space 
above the eyes sparsely, coarsely punctate, the legs not so stout. Less elongate than 
M. tenwipes, Faust, the head differently sculptured, the black apical patch sharply 
defined, &c. 
11. Metriophilus cribricollis, sp. n. 
Oblong-ovate, opaque, black, the antennae ferruginous; the prothorax very sparsely clothed with short, 
decumbent, blackish sete, the elytra with minute dark brown scales intermixed with rather coarse, 
semierect, blackish setee, which are here and there clustered into small fascicles, the scutellum ochreous ; 
the vestiture of the under surface and legs sparse, brownish. Head rugosely punctate, flattened above 
the eyes; rostrum strongly curved, somewhat gibbous at the base, rugose, shining and almost smooth
