560 RHYNCHOPHORA. 
1. Ganymela nitida. 
Ganymela nitida, Pasc. Ann. & Mag. Nat. Hist. (5) xvii. p. 4277. 
Hab. Panama}, 
An oblong, robust form, with a subquadrate prothorax, and uneven, oblong elytra. 
The unique type is a male, and it has the first ventral segment broadly excavate in the 
middle. ‘The locality seems to require confirmation. 
Sect. EuToxiDEs. 
Madarides vrais, Lacordaire (part.). 
Under this section are included the “‘ Madarids ” with the pygidium covered by the 
elytra in both sexes—Conoproctus, Madarus, and Dactylocrepis having the pygidium 
fully exposed,—the Eutoxides bearing much the same relation to the Madarides as do 
the Centrinides to the Barides. ‘The typical genus Eutoaus is remarkable on account 
of having the rostrum sometimes greatly elongated in the male, as in Madarus 
4-pustulatus, F.*. Calandromimus is a peculiar flattened form with the under surface 
very broadly excavate and more or less squamose down the middle in both sexes. 
EUTOXUS. 
Euioxus, Schénherr, Gen. Cure. viii. 1, p. 108 (1844) ; Lacordaire, Gen. Col. vii. p. 254. 
A genus including a few conspicuous Tropical-American forms, four of which occur 
in our region. ‘They may be separated thus :— 
Rostrum in ¢ straightened towards the base, and often very elongate in this sex, 
arcuate in 2. 
Prosternumn bispinose near the apex in ; elytra foveate nearapex . . . . foveatus. 
Prosternum unarmed in 3; propleura transversely tumid opposite the coxe ; 
elytra not foveate . . .. - moe ee ee ee ek  . dacordairei. 
Rostrum arcuate in both sexes, not greatly elongated in 3. 
Hilytra deeply excavate at base. . . - - . « . plicatilis. 
Elytra slightly depressed at base . soe ee ee Sraternus 
1. Kutoxus foveatus, sp. n. (Tab. XVIIL. fige. 15, 154, b, ¢ ; 16, 2.) 
Klongate, subfusiform, robust, nigro-piceous or black, shining; glabrous above, the punctures of the under 
surface and legs each bearing a minute whitish scale. Head closely punctate, transversely depressed 
between the eyes ; rostrum (¢ ) almost straight in its basal half and curved thence to the apex, moderately 
stout, longer than the body, somewhat closely punctate, (@) curved from the base, a little stonter and 
scarcely longer than the elytra, the antenne inserted at about the basal third, the scape not feadhing the 
eyes in the g, the club small, acuminate-ovate. Prothorax subconical, longer than broad in the re 
shorter in the 2, constricted just before the apex, the sides becoming subparallel towards the dee ly 
sinuate base, the median lobe long, rounded, and impinging on the scutellum ; closely, finel ane ‘ 
Elytra elongate-triangular, transversely depressed at the base and deeply foy tl fe vi 
: eate on the disc near the 
apex; finely punctate-striate, the punctures oblong, the interstices sparsely, minutely punctate, flat
