424 RHYNCHOPHORA. 
white line on each side of the disc of the prothorax dividing into two posteriorly, and 
continued on to the base of the elytra; the elytra with series of coarse, subquadrate 
punctures and scattered, clubbed, whitish sete, the alternate interstices interruptedly 
costate ; the mesosternum conically protuberant in front, &c. The Guatemalan 
examples (which are dirty) have the prothorax and elytra less coarsely punctate, and 
the vestiture a little closer and finer than those from Mexico. 
149. Conotrachelus punctiventris, sp. n. 
Subovate, robust, shining, black, the elytra and legs more or less mottled with rufo-piceous, the antenne of 
the same colour; the vestiture very sparse on the prothorax and under surface, closer and fasciculate on 
the elytra, becoming denser on the apical declivity, ferruginous or brownish, the elytra with a small 
fulvous or whitish spot at the base of the third interstice and sometimes another on the shoulder, the 
femora not annulate; the upper surface also set with numerous semierect, stiff, pallid sete, the legs 
setulose. Head closely, rugulosely punctate, transversely depressed above the eyes; rostrum (d) 
moderately stout, curved, distinctly longer than the head and prothorax, sharply 5-carinate, ( 9 ) a little 
more elongate and with the tip more sparsely punctate, the antenne inserted towards the apex, joints 1 
and 2 of the funiculus subequal in length. Prothorax transverse, rounded at the sides anteriorly, 
constricted and narrowed in front, deeply bisinuate at the base; coarsely, rugosely punctate, and usually 
carinate. Elytra slightly constricted behind the obliquely truncated humeri, deeply sinuate at the base, 
subparallel anteriorly ; seriate-punctate, the interstices rugulose and obsoletely granulate, 3, 5, 7, and 9 
uninterruptedly costate. Ventral segments coarsely, closely punctate. Mesosternum flattened between 
the cox, conically protuberant in the middle in front. Legs stout, rugose; femora acutely unidentate ; 
posterior tibiz slightly hollowed at the apex within in the ¢ ; tarsal claws with a long tooth. 
Length 3,1,-44, breadth 13-23 millim. (3 2.)

Ten specimens, varying greatly insize. Very like C. parvicollis, but with the rostrum 
longer, not so stout, smoother, and sharply 5-carinate; the vestiture rather sparser, 
the third elytral interstice with a small spot (instead of a rather long streak) at the 
base ; the mesosternum more protuberant in front ; the tarsal claws with a shorter, less 
curved tooth. The sculpture of the prothorax is variable, the median carina being 
sometimes absent. The single example from San Juan, a female, has a more elongate 
rostrum than the others of the same sex before me. ‘The stiffer seta and the 
conically protuberant mesosternum separate it from C. sguamifrons, C. posticatus, Kc. 
150. Conotrachelus uniformis, sp.n. (Tab. XXI. figg. 10, 10a.) 
Broad, robust, shining, rufo-piceous ; the vestiture dense and of a uniform pale brownish colour, each of the 
coarser punctures with a short, fine, decumbent, pallid seta. Head densely punctate; rostrum moderately 
stout, feebly curved, a little longer than the head and prothorax, densely, rugulosely punctate and very 
faintly 5-carinate, the apical portion abruptly becoming bare and sparsely punctate, the antennee inserted 
at about one-third from the apex, joints 1 and 2 of the funiculus equal in length. Prothorax convex, 
slightly broader than long, narrowed and constricted in front, parallel behind, the base moderately 
bisinuate; rather closely punctate, with the interspaces densely, minutely punctate, the disc somewhat 
gibbous at the middle. LElytra broad, triangular, comparatively short, the humeri obliquely truncate in
