CONOTRACHELODES.—METRANIA. 461 
CONOTRACHELODES, gen. nov. 
Rostral canal very deep, abruptly terminating a little before the apex of the metasternum; rostrum long, 
curved, and slender; prothorax with the ocular lobes almost covering the eyes; metasternum moderately 
long, with broad, parallel-sided episterna; ventral segments 3 and 4 rather long, together a little longer 
than 2 or 5, all the sutures straight ; tarsal claws toothed. 
The single species referred to this genus has almost exactly the facies of Cono- 
trachelus serpentinus, Boh., but, following the system of Lacordaire, it must be included 
amongst the “Sophrorhinides,” the rostral canal being long and deep, at least in the 
female, and abruptly terminated behind. 
1. Conotrachelodes octocostatus, sp.n. (Tab. XXII. figg. 21, 21a, 2.) 
Subovate, shining, nigro-piceous, the rostrum and antenne ferruginous; the vestiture fine and close, fulvous, 
slightly intermixed with whitish, the anterior femora with a short, dense, fulvous streak at the base above. 
Head densely rugulose ; rostrum punctato-sulcate at the sides, smooth above, the antenn inserted at 
the middle, joint 2 of the funiculus a little shorter than 1. Prothorax transverse, rather convex, 
subconical, strongly bisinuate at the base, constricted in front ; rugosely punctate and carinate. Elytra 
subtriangular, nearly twice as wide as the prothorax, deeply sinuate at the base, the humeri rounded ; 
coarsely seriate-punctate, the interstices very finely rugulose, 3, 5, 7, and 9 sharply costate, the ridges 
on 3 and 5 not extending beyond the middle forwards, 10 also costate at the base. Beneath very 
sparsely, coarsely punctate, the ventral segments 3 and 4 smooth. Femora unidentate. 
Length 5, breadth 2% millim. ( 2.)

METRANIA. 
Metrania, Pascoe, Journ. Linn. Soc., Zool. xi. p. 481 (1872); Jekel, Ann. Soc. Ent. Fr. 1873, 
p- 27, nota. 
Pascoe’s type of VM. palliata is no doubt a female, the male having a shorter rostrum 
and a correspondingly shorter canal for its reception, the latter not extending to the 
base of the abdomen in this sex. The prothoracic vibrissee are very short.

Eupterus anguliferus and E. pulcher, Jekel, in litt.’. 
Var. 3. The large chocolate-brown dorsal patch on the elytra almost obliterated, the surface mottled all over 
with small condensed patches of whitish scales, as at the sides and apex in the typical form( 2). Rostral 
canal not reaching beyond the apex of the metasternum.
