218 RHYNCHOPHORA. 
finely, punctate. Legs stout, finely punctate; femora sulcate and unarmed beneath ; tibie: broad, the 
intermediate and posterior pairs angulate externally near the base. 
Length 2, breadth 13 millim. 
Hab. Panama, Bugaba (Champion). 
One specimen. One of the smallest of the Central-American forms, and distinguish- 
able by the very short, stout rostrum, the finely striate elytra, and the broad tibiz, the 
intermediate and posterior pairs only angulate. The prothorax is unimpressed at the 
base, and the elytra are not depressed along the suture. 
14. Diorymerus sexstriatus, sp. n. 
Ovate, black, shining. Head sparsely, finely punctate, transversely depressed between the eyes ; rostrum very 
stout, short, closely punctate in the g, smoother in the 2. Prothorax smooth, the median lobe only 
with a few fine punctures, the base depressed on each side of it. Scutellum small, oblong. Elytra 
depressed along the suture, each with the three inner strie deep, and the others (the two marginal ones 
excepted) very faint or almost obsolete, these latter with scattered fine punctures. Beneath closely 
punctate, the flanks of the prothorax almost impunctate. Legs closely punctate ; femora sulcate and 
unarmed beneath; tibis almost straight, the intermediate and posterior pairs subangulate near the 
base externally. 
Length 31-31, breadth 2-21, millim. (d 2.) 
Hab. Gvaremaa, Chacoj and San Juan in Vera Paz (Champion: 3 2); PANAMA, 
Bugaba (Champion: @ ). 
One specimen from each locality. Very like D. cribrarius, but with the prothorax 
almost impunctate on the disc and flanks and the base depressed on each side of the 
median lobe, the three inner strie of the elytra deep and without definite punctures, 
the intermediate and posterior tibie less acutely dilated near the base, the ventral 
segments 3 and 4 distinctly punctate. 
15. Diorymerus ornatus, sp.n. (Tab. XII. fig. 23.) 
Ovate, shining, black, the elytra with a large rufous humeral patch. Head sparsely punctate, transversely 
depressed in front; rostrum short, arcuate, moderately stout, sparsely punctate, striate at the sides. 
Prothorax slightly depressed at the base on each side of the median lobe, smooth, the median lobe only 
with a few rather coarse punctures. Scutellum transverse. LElytra depressed along the suture, the first 
three stria and the marginal one well-defined (the sutural stria deep), the others almost obliterated, 
except at the base and apex, the strie with minute distantly-placed punctures. Beneath sparsely 
punctate. Femora rather coarsely punctate, sulcate and unarmed beneath. Tibie broad, unarmed 
within, all dentate on the outer edge near the base, the anterior pair also angulate near the tip. 
Iength 3, breadth 2 millim. (<?) 
Hab. Mexico (Dupont, in Mus. Brit.). 
One specimen. The large rufous humeral patch and the almost smooth outer 
portion of the dorsal surface of the elytra sufficiently distinguish D. ornatus. The 
minute, scattered, seriate punctures are conspicuous on the rufous portion of the 
surface, showing through from beneath. ‘The anterior tibie are angulate externally 
near the base and apex.
