KHYXCHOPHOKA. 



9. Metamasius scutiger, sp. n. ('Jab. v. figg. 17, 17 a, s .) 



Subfusiform, opaque above, black, the elytra with a very large, common, anteriorly-dilated, scutiform, fulvous 

 patch extending from the base to near the tip (leaving the shoulders, apex, and sides posteriorly, 

 black), the fifth interstice with a small black spot before the middle, the prothorax with two faint 

 reddish spots at the base. Head closely punctate, the frontal fovea oblong ; rostrum about as long as 

 the prothorax, feebly curved, the broad, abruptly-widened basal portion coarsely punctate, the apical 

 portion rather slender and very sparsely punctured, smooth at the tip. Prothorax as long as broad, 

 subconical, abruptly constricted in front, the hind angles rounded, the base bisinuate ; sparsely punctate, 

 the disc flattened posteriorly. Scutellum narrow, elongate-triangular. Elytra subcordate, finely striate, 

 the stride with scattered coarse punctures, the alternate interstices a little wider than the others. 

 Pygidium rather narrow, rugosely punctate. Beneath very sparsely punctate; first ventral segment 

 faintly sulcate along the middle. Tibiae curved externally, fringed with extremely short hairs. 



Length 6|, breadth 2| millim. ( 6 .)

Hdb. Panama, Bugaba (Champion). 



One specimen, assumed to be a male. A small form, with peculiar elytral markings, 

 and not very closely allied to any of the other species here enumerated. It has the 

 anterior and middle coxae widely separated. The prothorax in certain lights appears 



to hflvp a denser velvetv-black snot on the middle of the disc. 



10. Metamasius sulcirostris, sp. n. 



cJ. Oblong- elliptic, opaque above, pruinose, black, the lower part of the flanks of the prothorax (and in one 

 specimen two very faint parallel vittse on the disc also) rufescent. Rostrum very stout, arcuate, shorter 

 than the prothorax, broadly, sharply sulcate beneath (the sulcus with an acute median ridge), finely 

 punctate, the widened basal portion sulcate and rugosely punctured. Prothorax as long as broad, 

 rounded at the sides anteriorly, deeply bisinuate at the base, somewhat closely punctate laterally and 

 on the flattened portion of the disc, the rest of the surface with minute scattered punctures. Scutellum 

 oblong-triangular, hollowed down the middle. Elytra a little wider than the prothorax, subcordate, 

 finely punctate-striate, the interstices flat. Pygidium sparsely punctate, pilose. Beneath sparsely, 

 rather coarsely punctate; ventral excavation deep, the fifth segment with a few hairs towards the 

 apex. Anterior and intermediate coxae with a small tuft of hairs. Femora and tibiae finely ciliate, 

 the tibiae somewhat curved. 

 Length 12|-13, breadth 5 millim. 



Hdb, Guatemala, near the city (Salviri) ; Nicaragua, Chontales (Belt). 



Two males, agreeing precisely in their general structure. This species bears a close 

 resemblance to Cactophagus validirostris (Gyll.), bat may be separated from it 

 the narrow, non-sulcate peduncle of the submentum, the less approximate anterior 

 coxae, the deeply, inferiorly sulcate rostrum ( 6 ), the very sparsely and less coarsely 

 punctured prothorax, the base of which is strongly bisinuate, the longer hairs on the 

 pygidium, &c. It is possible that more distinctly rufo-maculate forms may occur. 



11. Metamasius cincixmatus, sp. n. (Tab. V. figg. 18, 18 a, b, 6 . 



cJ . Elongate, fusiform, somewhat convex, opaque above, shining beneath ; black, the prothorax and elytra 

 rufous, the former with a broad posteriorly bifurcate median vitta and a transverse patch on each side 

 at the base, and the latter with a transverse spot on each side below the shoulder, a common angulate 

 median fascia (widened inwards), and an oblong patch on the suture at the apex, black. Eostrum 

 stout, curved, much shorter than the prothorax, almost smooth ; sulcate, laterally crenate, and also 

 angulate at the tip, beneath ; the frontal fovea small. Prothorax longer than broad, flattened on the
