DIORYMERUS. 215 
Seven specimens. Extremely like D. fossulatus, but wanting the deep transverse 
frontal sulcus; the rostrum not so stout, smoother, and a little longer; the under 
surface and the femora more sparsely punctate; the anterior tibie dentate externally 
towards the apex, as well as near the base. ‘The legs are not so smooth as in 
D. levipes, and the tibie are more sharply toothed near the base externally; the 
prothorax, moreover, is not flattened across the disc in the male. 
6. Diorymerus erythropterus, sp.n. (Tab. XIT. figg. 15, 15a.) 
Subrhomboidal, very convex, shining, black, the elytra rufo-testaceous. Head somewhat closely punctate, 
shallowly, transversely depressed in front; rostrum short, moderately stout, closely punctate ; antennal 
club as long as the funiculus. Prothorax smooth, the base and apex with a few punctures, the base 
slightly depressed on each side of the median lobe. Scutellum subquadrate. Elytra subtriangular, 
slightly depressed along the suture, the humeri rounded and rather prominent ; with rows of extremely 
minute scattered punctures (the position of each of which is indicated by seriate coarse impressions 
showing through from beneath), the sutural and marginal strie only well-defined, the others obliterated. 
Beneath with very coarse scattered punctures, the ventral segments 2-5 much smoother, 1 broadly 
depressed in the middle. Femora coarsely punctate, deeply sulcate and unarmed beneath. Tibise broad, 
unarmed within, all angularly dilated on the outer edge near the base, the anterior pair also angulate 
near the apex. 
Length 32, breadth 24 millim. (¢.) 
Hab. Guavemata, near the city 500 feet (Salvin). 
One specimen. ‘The only Central-American species known as yet with the elytra 
rufo-testaceous and the rest of the body black. ‘The elytra are almost smooth on the 
surface (though there are rows of coarse punctures showing through from beneath), 
the sutural stria, however, is deeply impressed. 
7. Diorymerus fossulatus, sp. n. (Tab. XII. figg. 16, 16 a, 4.) 
Globose-ovate, shining, black, the upper surface with a distinct brassy lustre, the anterior tibiz fringed with 
short ochreous hairs at the tip. Head minutely punctate, with a very deep transverse frontal groove ; 
rostrum stout, curved, short, about as long as the lateral portion of the prothorax, thickly punctate ; 
antennse short, with a stout, ovate club. Prothorax depressed at the base on each side of the median 
lobe, almost smooth, the anterior lobe finely punctate, the lower part of the flanks, and the lateral 
portions of the meso- and metasternum also, with very coarse scattered punctures. Scutellum very 
small, Elytra with rows of minute scattered punctures, striate at the extreme base and along the 
suture and lower margin, the sutural stria with elongate, contiguous impressions. Intercoxal portion 
of the meso- and metasternum, and ventral segments 1 and 5, densely and coarsely, and ventral segments 
2-4 sparsely, punctate. Femora coarsely, closely punctate, deeply sulcate and unarmed beneath. Tibie 
proad, unarmed on their inner edge, dentate externally near the base, the tooth on the posterior pair 
long and curved inwards, the anterior pair hollowed and shallowly sulcate on their outer face. 
Length 34-4, breadth 23-3 millim. 
Hab, Guaremata, El Jicaro in Vera Paz (Champion). 
Six specimens. Recognizable amongst the allied species with obliterated dorsal 
stris by the very deep transverse frontal excavation, and the short, stout, thickly 
punctate rostrum. The sutural stria is catenulate-punctate; the first ventral segment 
is densely punctured ; and the anterior tibie are shallowly sulcate for the reception. of 
the tarsi In repose.
