bo 
somewhat swollen, the disc transversely hollowed at the base; finely punctate-striate, the interstices 
flat, becoming convex at the apex, each with a scattered row of very minute punctures. Beneath very 
sparsely, finely punctate ; first ventral segment excavate down the middle in the g. Prosternum tumid 
between the coxe in both sexes, unimpressed anteriorly, the transverse subapical groove longitudinally 
foveolate. Legs slender, the femora abruptly clavate; anterior tibiz serrate and closely ciliate within 
in the ¢, sparsely ciliate in the Q ; anterior tarsi somewhat hairy in both sexes. 
Length 5-53, breadth 21-22 millim. (d Q.)

One pair. Smoother than £. lacordairei, the rostrum more slender and strongly 
arcuate in both sexes, the prosternum more swollen between the coxe, the propleura 
not plicate, the anterior tibiz of the male serrate and more sparsely ciliate, the body 
entirely castaneous. 
4. Eutoxus fraternus, sp.n. (Tab. XVIII. figg. 20, 20@, o.) 
Subfusiform, robust, shining, faintly alutaceous, black, glabrous. Head closely punctate, transversely grooved 
between the eyes; rostrum arcuate, moderately stout, a little more than half the length of the body, 
slightly thickened at the base, closely punctate, the antenne inserted at about the basal third. Prothorax 
nearly as long as broad, subconical, rapidly and arcuately narrowing from about the basal third, the short 
tubulate apical portion separated by a distinct ridge, the median basal lobe long ; closely, finely punctate. 
Elytra triangular, moderately long, transversely depressed on the disc at the base ; finely punctate-striate, 
the interstices flat, convex at the apex, sparsely, very minutely punctate. Beneath sparsely punctate ; 
first ventral segment depressed down the middle, the fifth with a deep transverse fovea at the apex. 
Prosternum unimpressed, flattened between the very widely-separated anterior cox. Anterior tibiae 
sparsely ciliate within. Third tarsal joint moderately large. 
Length 72, breadth 31 millim. (¢.) 
Hab. Panama, Bugaba (Champion). 
One male. Smaller and less elongate than the same sex of E. foveatus, with a 
comparatively slender, arcuate, much shorter rostrum, the legs shorter, the tarsi less 
dilated, the elytra without subapical fovea, the fifth ventral segment deeply foveate. 
More robust and less shining than E. lacordairei, the prothorax more rounded at the 
sides, and with a sharply-defined “neck” in front, the elytra less excavate at the 
base, &c. The male-characters are less pronounced than in the allied forms, and the 
insect described at first sight appears to be a female. 
PSEUDEUTOXUS, gen. nov. 
Rostrum very slender, flattened, arcuate and much longer than the body in the 2, feebly curved and about 
as long as the elytra in the ¢, the scrobes lateral and very shallow, the antenne inserted at about the 
middle in the g and at the basal third in the Q, the scape not reaching the eyes, the joints of the 
funiculus obconic, the club acuminate-ovate ; mandibles abruptly dilated at the base externally in the 9, 
obsoletely so in the g, the basal portion in the ? crescentiform above (fig. 22a)*; prothorax abruptly 
tubulate in front and with the basal median lobe short ; scutellum free, small, trausverse, emarginate 
behind; elytra oblong-triangular ; pygidium not visible; prosternum unimpressed anteriorly, the broad 
* The crescentiform piece (of which there is no trace in the S), at first sight, appears to be attached to 
the apex of the rostrum ; but, so far as I can ascertain without dissection, it is really part of the mandible.
