462 RHYNCHOPHORA. 
METRANIOPSIS, gen. nov. 
Rostrum very long and stout, curved; antenne inserted at about the middle of the rostrum, the funiculus 
7-jointed, joints 1 and 2 subequal in length, the club ovate, with distinct sutures ; prothorax broad, 
angularly dilated at the sides, bisinuate at the base, without distinct ocular lobes, which are replaced by 
long vibrisse, the large, rounded, coarsely facetted eyes remaining almost uncovered in repose ; scutellum 
well-developed, rounded ; elytra wider than the prothorax at the base, each with ten rows of punctures, 
the sides vertical, the humeri prominent, but obtuse, the epipleura visible to the apex; anterior coxe 
moderately, the others a little more widely, separated; rostral canal deep, open behind, reaching the 
apex of the metasternum in the ¢ and that of the first ventral segment in the 2; metasternum short, 
the episterna broad; ventral segments separated by deep sutures, 3 and 4 a little shorter than 2 or 5; 
legs rather elongate; femora sharply dentate; tibie unguiculate at the outer apica] angle; tarsi with 
joint 3 broad and bilobed, the claws long, divergent, and simple. 
This genus is nearly related to Metrania, and has the rostral canal similarly formed ; 
* but it has a short metasternum, a broad, angularly dilated prothorax, mesially inserted 
antenne, &c. 
1. Metraniopsis elatus, sp.n. (Tab. XXII. figg. 23, ¢; 24, 2.) 
Oblong-ovate, broad, flattened above, opaque, alutaceous, black, the antenne and the tips of the tarsi 
sometimes ferruginous; clothed with scattered intermixed fulvous scales and coarse, blunt, erect, 
fulvous and black sete; the fulvous vestiture condensed into a patch on the middle of the disc of the 
» prothorax behind, surrounding an oval whitish spot, which is continued on to the scutellum, and that on 
the elytra into a patch on each side of the scutellum and an indistinct transverse subapical fascia; the 
elytra also each with a minute whitish spot towards the tip and the prothorax with two others at 
the apex; the velvety-black sets: condensed on the front of the head, at the sides and around the dorsal 
patch on the prothorax, and forming various streaks and spots on the elytra; the under surface very 
sparsely, the legs densely, squamose, the latter annulate. Head densely punctate, carinate and trans- 
versely depressed in front, the eyes rather narrowly separated ; rostrum punctato-sulcate and carinate in 
its basal half, almost smooth thence to the tip. Prothorax strongly transverse, angularly dilated at the 
sides and there nearly or quite as wide as the elytra, constricted and much narrowed in front; finely 
punctate on the disc and at the sides. Elytra seriate-punctate, the punctures oblong in shape and 
distant one from another, the interstices flat, the ninth sharply costate. Beneath sparsely, rather 
coarsely punctate, the ventral segments 2-4 and the metathoracic episterna each with a single row of 
punctures. First ventral segment in the Q with two small fascicles of fulvous scales at the apex. 
Length 6-74, breadth 34-4 millim. (¢ 9.)

Four specimens. 
METRANIELLA, gen. nov. 
Head deeply sunk into the prothorax, the eyes lateral, coarsely facetted; rostrum feebly curved, elongate, 
reaching the apex of the first ventral segment; antenna inserted at about one-third from the base of 
the rostrum, the funiculus 7-jointed, joints 1 and 2 subequal in length, 3 much shorter, the club ovate, 
with distinct sutures ; prothorax short, strongly sinuate at the base, without ocular lobes ; scutellum not 
visible ; elytra much wider than the prothorax, closely embracing the sides of the metasternum and 
covering the episterna beneath, 10-striate; metasternum extremely short; ventral segments 2-4 very 
short, equal, 1 longer and almost vertical; legs short and stout; anterior femora dentate; tibie strongly 
unguiculate at the outer apical angle; tarsi with joint 3 broadly bilobed, the claws very small and 
narrowly separated ; rostral canal becoming raised and trough-like posteriorly, projecting over the first 
ventral segment. 
Ihe small species referred to this genus is related to Metrania and Thrasyomus, the
