214 RHYNCHOPHORA. 
3. Diorvmerus perlevis, sp.n. (Tab. XII. figg. 13, 13a; 134, ant. tibia.) 
Short ovate, very convex, shining, black. Head almost smooth, transversely depressed and faintly foveate 
between the eyes; rostrum short, exceedingly stout, strongly arcuate, sparsely punctate. Prothorax 
smooth, depressed at the base on each side of the median lobe. Scutellum short, transverse, flat. 
Elytra with a shallow sutural and two distinct marginal striw, these striae with fine scattered punctures, 
the others obliterated. Beneath with a few scattered punctures. Legs sparsely punctate; femora 
sulcate and unarmed beneath ; intermediate and posterior tibia almost straight, angularly dilated near 
the base externally ; anterior tibie sinuous, obsoletely denticulate along their inner edge. 
Length 22, breadth 13 millim. (<2?) 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
One specimen. Shorter and smaller than D. levissimus, the scutellum transverse, 
the sutural and marginal striz of the elytra less distinct, the anterior tibiz obsoletely 
denticulate within, the other tibize angulate at the base externally. 
4, Diorymerus levipes, sp.n. (Tab. XII. figg. 14, 14a, g; 144, ant. tibia.) 
Globose-ovate, shining, black. Head smooth, unimpressed ; rostrum short, curved, striate and faintly punctate 
at the base, almost smooth in the 2; antennal club nearly as long as the funiculus. Prothorax depressed 
at the base on each side of the median lobe, feebly constricted in front, smooth ; the disc feebly nodose 
on each side, and the intervening space broadly flattened, in the ¢. Scutellum transverse. Elytra with 
rows of scattered minute punctures, striate at the base and near the suture, the sutural stria more 
coarsely punctate towards the base. Beneath very sparsely punctate, the meso- and metasternal side- 
pieces smooth ; metasternum and first ventral segment broadly excavate down the middle in the ¢. 
Femora and tibize with a few minute scattered punctures ; femora deeply sulcate and unarmed beneath, the 
anterior pair widened at the base ; tibise broad, hollowed for the reception of the tarsi in repose, unarmed 
within, the anterior pair angularly dilated on the outer edge near the base and also near the apex (the 
median third widened), the intermediate and posterior pairs more or less angulate near the base externally. 
Length 43-54, breadth 33-4 millim. (¢ 9.) 
Hab. Nicaracua, Chontales (Belt, Janson: ¢ 2); Panama, Volcan de Chiriqui 
(Champion: 3). 
Four specimens, the one from Chiriqui (a ¢ ) much larger than the others and with 
a distinct rounded prominence on each side of the flattened space on the disc of the 
prothorax. The femora are almost smooth, and the anterior tibie are dilated on their 
outer edge for rather more than the median third. The Chiriqui example is figured. 
5. Diorymerus leviusculus, sp. n. 
Globose-ovate, shining, black, the upper surface with a faint brassy lustre. Head very sparsely, minutely 
punctate, obsoletely foveate in front, without transverse frontal groove; rostrum short, curved, moderately 
stout, very sparsely punctate, smoother in the 2. Prothorax depressed at the base on each side of the 
median lobe, almost smooth. Scutellum transverse. Elytra with rows of minute scattered punctures, 
which become coarser at the base and along the impressed sutural stria. Beneath very sparsely, coarsely 
punctate, the ventral segments 2—4 and the sides of the metasternum with a few scattered fine punctures 
only ; metasternum and first ventral segment broadly excavate down the middle in the ¢. Femora 
sparsely punctate, deeply sulcate and unarmed beneath; the anterior pair widened at the base. Tibia 
broad, unarmed on their inner edge, dentate externally near the base, the tooth on the posterior pair 
long and curved inwards, the anterior pair also dentate near the apex and narrowed thence to the tip. 
Length 33-44, breadth 22-32 millim. (¢ 2.) 
Hab. Mexico, Atoyac in Vera Cruz, Teapa (H. H. Smith); Guatemata, Coban 
(Conradt), Panima and San Juan in Vera Paz (Champion).
