282 RHYNCHOPHORA. 
Hab, Guaremata, San Gerénimo in Baja Vera Paz (Champion). 
Two females. This insect is of about the same size and shape as the Mexican 
G. iners, but the vestiture is much finer, the elytral interstices are flat and closely 
punctate, &c. It is narrower than G. coarctatus, the prothorax is narrowed from the 
base, and the elytral interstices are rugosely punctate, each with two lines of short, fine, 
setiform scales. The prosternum is perhaps spined in the male. 
43, Gerzeus albolineatus, sp.n. (Tab. XV. figg. 15,15 a, 3; 16,16 a, 2, var.) 
Oblong-rhomboidal, very shining, black ; the prothorax with the outer margins and hind angles, the elytra with 
various elongate streaks on the alternate interstices 2, 4, 6, 8 (sometimes extending down their entire 
length) and a spot at the base of the third, and the under surface, densely clothed with coarse, oblong, 
pure white scales, the legs and rostrum with finer white scales, the rest of the upper surface (a few 
scattered scales excepted) in great part bare. Head finely punctate, transversely depressed between the 
eyes; rostrum (¢') long, strongly arcuate, moderately stout, thickly punctate to the tip, (2) more 
elongate, somewhat gibbous at the base, and with the apical two-thirds slender and almost smooth, the 
antenne inserted at (¢) or behind (@) the middle, joint 2 of the funiculus a little longer than 3, the 
club ovate. Prothorax transverse, narrowing from the base, strongly constricted in front; very finely 
punctate, except along a narrow median space, the punctures confluent along the sides and on the flanks. 
Scutellum small, transverse, bare. Elytra moderately long, narrowing from the base; narrowly and 
sharply striate, the strie feebly punctate, the interstices broad and flat, the squamigerous spaces 
punctulate. Beneath densely punctate. 
Var, The white streaks on the elytra less elongate, and tending to form three interrupted fascizae—one at the 
base, another beyond the middle, and a third at the apex; the white scales on the prothorax sometimes 
extending across the base. (Fig. 16.) 
$. Prosternum armed with two moderately long spines and with a deep fovea between them, or with two 
tubercles and a shallow excavation ; first ventral segment depressed down the middle. 
Length 34-44, breadth 13-22 millim. (¢ 2.) 
Hab, Mexico (Truqut, in Mus, Brit.), Toxpam (Sallé: 3 2), Atoyac (H. H. Smith: 
2 ), Oaxaca (Hoge: ¢); GuatEmALa, Capetillo (Champion: 3); Costa Rica, San José 
(U.S. Nat. Mus.) ; Panama, Volcan de Chiriqui (Champion: @ ). 
A variable insect. Of the fourteen specimens seen, nine are from Mexico (four 
having the white lines continuous on the elytra); the others belong to the varietal 
form, the male from Guatemala being a small narrow example with the prosternal 
spines reduced to two tubercles. 
44, Gereus x-notatum, sp.n. (Tab. XV. figg. 17, 17a, 2.) 
Oblong-rhomboidal, narrow, shining, black, the antennal club and the tip of the rostrum ferruginous ; the 
prothorax with a space along the sides, and the elytra with a transverse fascia at the base and a broader 
oblique one beyond the middle, the two fasciz connected along the suture, somewhat thickly clothed 
with narrow white scales ; the under surface, the basal portion of the rostrum, and the legs also clothed 
with small white scales, these becoming coarser and denser on the prosternum and on the meso- and 
metasternal side-pieces. Head finely punctate, transversely depressed between the eyes; rostrum long, 
abruptly bent downward near the base, the basal portion stout, somewhat gibbous, and thickly punctate 
at the sides, the apical portion feebly curved, flattened, rather slender, and almost smooth, the antennez 
inserted behind the middle, joint 2 of the funiculus twice as long as 3, the club short-ovate. Prothorax 
transverse, subconical, constricted in front; closely punctate, except along the middle, the punctures 
coniluent at the sides, Scutellum transverse. Elytra subtriangular, deeply striate, the strie feebly
