16 RHYNCHOPHORA. 
the sides almost straight to beyond the middle, the humeri rounded; flattened on the disc, depressed 
behind the scutellum, rather finely seriate-punctate, the interstices flat. Venter depressed along the 
middle towards the base. 
Length 133-15, breadth 43-5 millim. (¢ Q.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Six specimens, apparently including both sexes, some of them having a longer 
ventral depression than others. Distinguishable from all the other Central-American 
forms by the disposition of the white markings on the elytra, these showing no tendency 
to vary. The antennal grooves are only separated by a very narrow ridge at the base 
of the rostrum beneath. 
16. Hilipus albomaculatus, sp. n. (Tab. II. fig. 2, 2.) 
Oblong-oval, moderately shining, piceous ; the prothorax with a broad vitta on each side, narrowing in front, 
this being continued on the elytra to near the middle in the form of a broad, curved, submarginal band, 
and the elytra also with a broad auteapical fascia, not quite reaching the suture, white; the under surface 
and legs with scattered, narrow, white scales. Head deeply foveate between the narrowly separated eyes ; 
rostrum distinctly longer than the prothorax, curved, stout, coarsely, closely punctate and obsoletely 
carinate towards the base, much smoother at the tip, the antennal grooves narrowly separated behind 5 
joints 1 and 2 of the funiculus subequal in length. Prothorax about as long as broad, narrowed in front 
and slightly so behind, sparsely punctate, with a narrow smooth space down the middle towards the apex. 
Elytra moderately elongate, widest a little below the base, conjointly rounded at the apex, the humeri 
broadly rounded and not at all prominent ; rather finely seriate-punctate, the interstices flat, the scutellar 
region depressed. 
Length 14, breadth 34 millim. (9.) 
Hab. Guatemata, Senahu in Vera Paz (Champion). 
One specimen. Very like H. albonotatus, but more robust, with shorter and stouter 
legs, the elytra broader and widest a little below the base, the prothoracic vitte 
continued on to the basal portion of the wing-cases in the form of a broad, curved, sub- 
marginal stripe, which extends inwards to the third row of punctures, and (like the 
subapical fascia) is not excised on either edge. 
17. Hilipus stictopterus, sp. n. (Tab. II. figg. 3, ¢ ; 4, 3, var.) 
Elongate-oval, dull or slightly shining, black or piceous, the head and rostrum usually rufescent; the pro- 
thorax with a broad vitta on each side above and a narrow line in front of the anterior coxe whitish or 
pale ochreous; the elytra with numerous, more or less coalescent, similarly-coloured spots towards 
the sides, extending from the base to the apex; the under surface, legs, and rostrum with scattered, 
narrow, whitish scales. Head very deeply foveate between the eyes, which are narrowly separated ; 
rostrum about as long as the prothorax, stout, curved, thickly and rather coarsely punctured, except at 
the tip, which is much smoother ; antenne inserted a little before the apex of the rostrum, joint 1 of the 
funiculus slightly longer than 2. Prothorax as long as broad, narrowing from the middle forwards ; 
the surface closely punctate in some examples, almost smooth in others, and with indications of a 
smooth, raised, central line anteriorly. Elytra elongate, one-half wider than the prothorax, very 
gradually narrowing from the base, conjointly rounded at the apex, the humeri rounded; flattened on the 
disc, depressed behind the scutellum, seriate-punctate, the interstices broad and faintly transversely 
wrinkled. Ventral segments 1 and 2 with a few scattered punctures, and in the ¢ broadly depressed 
along the middle.
