short, equal, the third one half longer than the second, subclavate. Thorax broader 
than long, subconic; sides obliquely converging from base to apex, constricted before 
the middle, anterior angle armed laterally with a short obtuse tooth; subcylindrical, 
flattened and broadly excavated on the hinder disc, impressed with large round punc- 
tures, well defined on the medial disc, shallower and less distinct on the sides. Elytra 
elongate, parallel, the apex regularly rounded, entire; lateral margin serrulate, 
apical border armed with regularly placed acute teeth; above convex, flattened along 
the suture; each elytron with ten, in the middle with nine, rows of large deeply 
impressed punctures; the suture, together with the second, fourth, sixth, and eighth 
interspaces, costate, the sixth interrupted on its middle third; fulvous, the apical third, a 
sutural vitta, together with a short line on the humeral callus, black. Legs elongate, 
the apices of the anterior tibie thickened. 
32. Chalepus vicinalis. 
Elongatus, parallelus ; subtus niger, nitidus, thoracis margine antico prosternoque fulvis; supra minus nitidus, 
fulvus, capite scutelloque nigris; thorace transverso, lateribus bisinuatis, medio distincte angulatis ; 
fortiter subcrebre punctato, lateribus extremis vittaque discoidali nigris; elytris parallelis, apice rotun- 
datis, marginibus obsolete serrulatis, margine apicali dentibus brevibus armato; utrisque decem- prope 
medium nono-seriato-punctatis, interstitiis elevato-reticulatis; interspatiis secundo, quarto octavoque sat 
valde costatis, sexto basi et apice minus distincte elevato; vitta lata suturali, a basi ad medium extensa, 
parteque tertia apicali, nigris. 
Long. 33 lin. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). A single specimen. 
Vertex and front impunctate, the latter trisulcate ; interocular space rather strongly 
produced. Antenne more than one third the length of the body, robust, thickened 
towards the apex ; joints cylindrical, the third nearly one half longer than the second. 
Thorax transverse ; sides angulate, bisinuate, nearly parallel from the base to the 
middle, thence obliquely converging to the apex; disc subcylindrical, transversely 
excavated behind, deeply impressed with large round punctures. lytra parallel, 
regularly rounded at the apex; sides obsoletely serrulate, apical margin denticu- 
late; each elytron with ten, the medial disc with eight or nine, rows of punctures, 
the sixth and seventh rows being more or less obsolete in the middle part of their 
course ; second, fourth, and eighth interspaces rather strongly costate, sixth interspace 
slightly elevated at base and apex. 
Nearly allied to the preceding species. The thorax broader, distinctly angulate on the 
sides, the apical teeth of the elytra shorter, the interspaces between the discoidal coste 
more distinctly elevate-reticulate. 
88. Chalepus consanguineus. (Tab. III. fig. 13.) 
Elongatus, parallelus, niger, nitidus; thorace elytrisque subnitidis, fulvis; illo transverso, lateribus leviter 
angulatis, crebre punctato; margine laterali anguste, vittaque lata discoidali, antice abbreviata, nigris ; 
elytris parallelis, apice rotundatis, margine laterali obsolete, apicali distincte, serrulatis ; utrisque decem-
