CONOTRACHELUS. ol 
punctate and sextuberculate), the first ridge on-the elytra more broadly interrupted 
posteriorly, the outer femoral tooth reduced to a small prominence, the tarsal claws 
with a longer tooth, the general vestiture less dense, that of the under surface much 
shorter and finer. There is an allied form from Colombia in the British Museum. 
89. Conotrachelus unifasciatus, sp.n. (Tab. XX. figg. 1, la, 2.) 
Subovate, opaque, nigro- or rufo-piceous, the antenn and tarsi ferruginous ; the vestiture fine, rather sparse, 
brownish, the prothorax with a condensed, whitish or ochreous, sinuous line on each side of the disc, 
extending on to the humeri of the elytra, and one or two faint lines at the sides, the elytra with a broad, 
common, outwardly narrowed, sordid white transverse fascia beyond the middle, the femora indistinctly 
biannulate with white. Head densely, rugosely punctured, shallowly foveate between the widely 
separated eyes; rostrum (¢) very stout, curved, about as long as the head and prothorax, rugose and 
feebly tricarinate, the apical portion shining and somewhat thickly punctate, (2 ) much smoother beyond 
the middle, the anteunz inserted towards the tip, joint 2 of the funiculus shorter than 1. Prothorax 
transverse, abruptly narrowed in front, the sides subparallel and crenulate, the base rather feebly 
bisinuate ; densely, rugulosely punctate, the disc bituberculate a little before the middle, and sometimes 
obsoletely carinate anteriorly. Elytra constricted and angularly dilated beneath the humeri, and 
narrowing from a little beyond this to the apex, the base feebly sinuate; very coarsely and deeply 
seriate-punctate, the punctures not very closely placed, the interstices 3, 5, 7, and 9 sharply costate, the 
ridge on 3 and 5 twice, and that on 7 once, broadly, abruptly interrupted, the median elevation on 3 
very prominent. Mesosternum flattened between the cox, bituberculate in front. Ventral segments 
sparsely punctate, 5 feebly trifoveate in the ¢. Femora clavate, bidentate, the outer tooth small. 
Tarsal claws with a short tooth. 
Length 43-5, breadth 23-22 millim. (¢ 92.) 
ilab. Mexico, San Andres Tuxtla (Sallé), Oaxaca (Hoge); GuatTeMaLa, Zapote 
(Champion). 
Four specimens. This insect approaches C. discifer, but the eyes are widely separated, 
the rostrum is more rugose at the base, shorter, and stouter, the elevations on the 
anterior half of the disc of the elytra are shorter, the fulvous line on the anterior 
femora is wanting, the prothorax has a sharply defined whitish line on each side of 
the disc, &c. 
90. Conotrachelus albofasciatus, sp.n. (Tab. XX. figg. 2, 2a, ¢.) 
Subovate, somewhat depressed, rather shining, black or piceous, the elytra sometimes with the apex and a 
subapical fascia rufescent, the antenne and tarsi ferruginous ; the vestiture close, fine, grey, slightly 
intermixed with white, the elytra with a broad, dense, irregular, subapical white fascia, extending on to 
the metasternum beneath, the prothorax with an oblique ochreous line on each side of the dise running 
forwards from the hind angles, the two lines nearly meeting at the apex, and continued down the 
rostrum and extending posteriorly on to the humeri of the elytra, the femora densely biannulate with 
white. Head densely punctate, slightly depressed in front; rostrum very stout, arcuate, about as long 
as the head and prothorax, densely rugulose and unicarinate, smoother at the tip in the 2, the antenne 
inserted towards the apex, joint 2 slightly shorter than 1. Prothorax transverse, abruptly narrowed and 
constricted in front, bisinuate at the base; the surface uneven, densely rugulosely punctate, carinate 
anteriorly, the dise with indications of two or four very small prominences. Elytra subparallel anteriorly, 
slightly constricted below the humeri, which are somewhat obliquely truncated in front ; seriate-punctate, 
the interstices rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 3 and 5 each broadly and abruptly 
twice interrupted, that on 7 entire. Mesosternum flattened between the coxa. Ventral segments very
