EUTOXUS. 361 
somewhat raised at the apex. Beneath sparsely punctate; first ventral segment deeply sulcate, and the 
fifth densely punctate and fulvo-pilose, in the ¢. Prosternum in the ¢ becoming tumid in the middle 
anteriorly and there armed on each side with an outwardly-projecting, smooth, conical tubercle, arcuate- 
emarginate at the base. Anterior tibise ciliate within in both sexes, densely so, and also feebly serrate, 
in the ¢. ‘Tarsi hairy and with large penultimate joint in both sexes. 
Length 114-124, breadth 44-42 millim. (¢ 2.) 
Hab. Panama, Bugaba (Champion). 
One male and two females. ‘This insect agrees very nearly with Lacordaire’s 
amplified description of EZ. reflexus, Boh., from Brazil; but the male differs from a 
specimen of that insect before me in having the rostrum stouter, the prothorax more 
elongate and more gradually narrowed forwards, the elytra deeply foveate near the apex 
and with the interstices flat for about four-fifths of their length and the punctures in 
the strize oblong in shape, and the fifth ventral segment densely pilose. 
2. Eutoxus lacordairei, sp. n. (Tab. XVIII. figg. 17, 17a, 3 ; 18, 2.) 
Somewhat fusiform, shining, nigro-piceous or black, almost glabrous. Head small, closely punctate, trans- 
versely depressed between the eyes; rostrum(¢ ) nearly as long as, or fully two-thirds the length of, the 
body, moderately stout, thickened, almost straight, and coarsely punctate in its basal third, the outer 
portion arcuate and more sparsely punctured, (Q) arcuate from the base and as long as in the smaller 
males, the antenne inserted behind the middle, the scape in the g not nearly reaching the eyes. 
Prothorax about as long as broad, the sides parallel for about their basal third and then abruptly and 
obliquely convergent to the narrow apex, feebly constricted in front, the median basal lobe long 
and nearly covering the scutellum; finely, somewhat closely punctate. Elytra triangular, transversely 
excavate at the base; finely punctate-striate, the interstices flat, convex at the apex, with very minute 
scattered punctures, which are uniseriately arranged towards the sides. Beneath closely punctate 
laterally, sparsely and more finely so down the middle ; first ventral segment flattened along the centre. 
Prosternum rather convex, unimpressed behind the foveolate, transverse subapical groove. Propleura 
transversely tumid and subcostate opposite the very widely-separated coxe. Anterior tibiz densely 
ciliate and crenulate within in the ¢, sparsely ciliate in the Q. 
Length 53-74, breadth 2-3 millim. (¢ Q.) 
Hab. Panama, Volcan de Chiriqui, Bugaba (Champion). 
Three males and one female. Smaller and less elongate than E. foveatus, the 
propleura transversely swollen opposite the anterior coxe, the prothorax abruptly and 
obliquely narrowed from the parallel-sided basal portion, the elytra not foveate near 
the apex. The rostrum of the male varies in length, and it is sometimes not longer 
than in the female. 
3, Eutoxus plicatilis, sp.n. (Tab. XVIII. figg. 19, 194, ¢.) 
Somewhat fusiform, castaneous, shining, glabrous, Head small, finely punctate, transversely depressed between 
the eyes; rostrum strongly arcuate, moderately stout, thickened towards the base, in the ¢ more than 
half the length of the body and sparsely punctate, in the 2 a little shorter and stouter, more coarsely 
punctate, and somewhat gibbous at the base, the antennve inserted far behind the middle, the scape not 
reaching the eyes in the Jd, the club acuminate-ovate, small. Prothorax a little broader than long, conical, 
constricted in front, the sides becoming subparallel at the base, the base itself deeply sinuate and with a 
long median lobe; very sparsely, minutely punctate. Elytra subtriangular, the humeri rounded and
