DIORYMERUS. 221 
depressed. Beneath (the ventral segments 3 and 4 excepted) coarsely punctate, the punctures on the 
pro- and mesopleura large and rounded. Legs stout, closely punctate; femora deeply sulcate and 
unarmed beneath, the anterior pair strongly dilated at the base; intermediate and posterior tibia dentate 
and broadly dilated externally near the base, and narrowing thence to the apex, the anterior tibize 
hollowed on the inner edge near the apex and somewhat curved externally. 
Length 24-32, breadth 14-2} millim. (¢ @.) 
Hab. Mexico, Frontera in Tabasco (Hége); British Honpuras (Blancaneaua) ; 
GuaTeMaLa, Teleman in Vera Paz (Champion). 
Six specimens. Easily recognizable by the rufescent upper surface, the dilated 
intermediate and posterior tibize (which are also each armed with a stout, inwardly- 
curved, dentiform projection near the base), and the basally widened anterior femora. 
22. Diorymerus levissimus, sp. n. 
Ovate, shining, black. Head smooth, transversely depressed in front; rostrum stout, strongly arcuate, 
sparsely punctate, rugulose along the sides; joint 7 of the funiculus strongly transverse and forming 
part of the club. Prothorax smooth, feebly constricted in front. Scutellum small, oblong-subquadrate. 
Elytra with the sutural and marginal striz only present, the others obliterated, except at the base, the 
marginal strie shallowly catenulate-punctate. First ventral segment closely punctate, unimpressed, 
the rest of the under surface with a few widely scattered punctures. Femora sparsely punctate, sulcate 
and unarmed beneath. ‘Tibie straight, rather narrow, unarmed within and rounded at the base 
externally. 
Length 3, breadth 2 millim. (2?) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One specimen. A very smooth form, with the sutural and marginal striz of the 
elytra alone visible, the marginal strie catenulate-punctate, the scutellum oblong, 
the legs rather slender, the tibie straight and not angulate externally near the base. 
23. Diorymerus canaliculatus, sp. n. (Tab. XII. figg. 29, 29a; 294, 
anterior leg.) 
Ovate, black, shining. Head with a few minute scattered punctures, transversely depressed between the 
eyes ; rostrum stout, fully as long as the prothorax, sparsely, finely punctate. Prothorax very sparsely, 
minutely punctate, canaliculate down the middle, the base slightly depressed on each side of the median 
lobe. Scutellum small, subquadrate. Elytra finely striate, the strie feebly punctate, becoming deeper 
towards the suture and almost obsolete on the outer part of the disc. Beneath, the flanks of the 
prothorax included, coarsely, sparsely punctate, the ventral segments more finely punctured. Legs 
closely punctate ; femora sulcate beneath, the anterior pair feebly denticulate along the edges of the 
sulcus; tibie almost straight, the anterior pair finely denticulate along their outer edge, the others 
subangulate near the base externally. 
Length 24, breadth 13 millim. (2?) 
Hab. Panama, Bugaba (Champion). 
One specimen. Near D. serrulatus, the anterior (instead of the intermediate and 
posterior) femora feeebly denticulate beneath, the anterior tibiz also denticulate along 
their outer edge (not sharply angulate at the base), the prothorax canaliculate, the 
elytra scarcely depressed along the suture.
