134 -  -RHYNCHOPHORA. 
Oblong, nearly glabrous, not strongly shining, piceous-black or brown with head black. Rostrum rather wide, 
shining, with a subtriangular impression over mouth, fringed at the sides with erect fulvous bristles, vertex 
finely reticulate and punctured; antennal club infuscate, elongate-oval. Prothorax transverse, with the 
sides straight and subdivergent from base to middle, thence strongly rounded to apex but not constricted, 
lateral margin carinate to before the middle; surface with fine and very close strigose punctuation, flanks 
pubescent anteriorly. Scutellum rounded. Elytra a little wider at base than prothorax, and not quite 
twice as long, subparallel-sided to posterior third; surface subimpressed round the scutellum, striate, the 
striee with traces of punctuation, wider posteriorly, interstices finely reticulate and multipunctate, flat at 
base, becoming subconvex about the middle, narrowed on the somewhat flattened declivity, feebly 
tuberculate and set with short decumbent sete. Underside piceous, thinly pubescent. Legs piceous, 
apical process of the anterior tibie conspicuously bifurcate. 
Hab. Guatemata, El Tumbador, Cerro Zunil (Champion). 
Three specimens. The genera of Bothrosterni are not very clearly delimited, and 
this insect presents a curious combination of the features of the three previously. 
described. 
PAGIOCERUS. 
Pagiocerus, Kichhoff, Berl. ent. Zeitschr. 1868, p. 148; Chapuis, Syn. Scol. p. 26 (Mém. Soc. 
Liége, 1873, p. 234). 
The species of Pagiocerus are less elongate than those of allied genera, and have the 
head distinctly rostrate, the rostrum being narrowed and bordered at the sides by the 
acute ridges, marking the anterior limit of the deep antennal fosse. The funiculus is 
widened towards its apex, the club is oval, compact, with curved sutures, the two 
shining basal joints occupying barely half its surface. The prothorax has no acute 
side-margin, and its sculpture consists of rounded or oval punctures, between which the 
interspaces are wrinkled so as to produce a strigose appearance. The spines of the 
anterior tibie are strong; the apical processes of the middle and hinder pairs are 
obsolescent and represented by a small spine only at the upper angle, the middle pair 
has two small teeth, the hinder one on the upper border. 
Two species of Pagiocerus, both Neotropical, have been described, of which one 
has been found in Central America.

Pagiocerus rimosus, Hichh. Berl. ent. Zeitschr. 1868, p. 148°; Chap. Syn. Scol. p. 26 (Mém. 
Soc. Liége, 1873, p. 234)”. 
Ovate, moderately shining, varying in colour from ferruginous to piceous-black, usually piceous-black with the 
apical margin of the prothorax and the elytra brown. Rostrum (¢ ) somewhat longer than broad, deeply 
impressed over the mouth, and armed with a recurved spine, bituberculate at the base and separated by 
an arcuate impression from the front, which is longitudinally impressed and shagreened ; rostrum ( 2 ) 
broader, less deeply impressed, its spine reduced to a tubercle, its lateral ridges set with erect sete, 
becoming longer towards the vertex (indistinct in the male), front subnitid and with a shallower impression 
between the eyes; antennz ferruginous, the club infuscate. Prothorax subtransverse, the sides nearly 
straight behind, strongly rounded in front, and constricted behind the apex; disc convex, with close
