ultimis intime approximatis, articulo ultimo acuto. 
Long. 33-4 lin. 
Rio Hondo (Blancaneaus) : GUATEMALA, Yaabal (Sallé), Zapote, San Gerénimo, La 
Tinta, Tamahu, Chiacam, Panima (Champion) ; Nicaraaua, Chontales (Bele). 
Front deeply trisulcate ; interocular space strongly produced, the apical portion of 
its upper surface with a short longitudinal ridge. Antenne nearly half the length of 
the body, rigid, obsoletely thickened towards the apex, the five outer joints very closely 
articulated, the apical one very acute. Thorax transverse, subconic; sides obliquely 
converging from base to apex, bisinuate, obtusely angulate in the middle, anterior angle 
armed laterally with a short acute tooth; upper surface subcylindrical on the sides 
and at the apex, transversely depressed and excavated on the hinder disc, covered with 
coarse but shallow foveolate punctures, the apical margin nearly impunctate. LElytra 
narrowly oblong, parallel, regularly rounded at the apex, finely serrulate, apical border 
with a few spinous teeth ; convex on the sides, flattened along the suture; each elytron 
with ten, at the extreme base with eleven, rows of punctures, the fifth to the eighth rows 
sometimes confused and irregular on the middle disc; second. and fourth interspaces 
strongly and equally costate} the basal portion of the sixth, together with the whole of 
the eighth, less strongly elevated. 
Separated from the two preceding species, to which it is otherwise closely allied, by 
the presence of the additional short row of punctures at the base of the elytra. 
56. Chalepus contubernalis. 
Elongatus, niger, nitidus; pectoris medio, thorace elytrorumque vitta lata laterali, a basi fere ad medium ex- 
tensa, fulvis ; thorace transverso, subconico, lateribus bisinuatis, disco pone medium transversim excavato, 
rude et crebre foveolato-punctato, vitta lata discoidali, apice attenuata, nigra; elytris subelongatis, 
parallelis, apice rotundatis, lateribus tenuiter, apice magis distincte, serrulatis; utrisque decem, basi 
extrema undecim, seriato-punctatis, interstitiis elevato-reticulatis ; interspatiis secundo, quarto et octavo 
totis, nec non sexto basi, costatis.

Hab. GuatemaLa, San Gerénimo (Champion). 
Head nitidous, front strongly trisulcate, the middle groove broad; interocular space 
strongly produced, obtuse. Antenne subfiliform, the second joint slightly shorter than 
the basal one, submoniliform, the third nearly one half longer than the second. Thorax 
transverse, subconic; sides converging from base to apex, bisinuate, the anterior and 
posterior angles subacute ; upper surface transversely convex, transversely excavated on 
the hinder disc, strongly, coarsely, and irregularly punctured. Scutellum quadrate- 
oblong. Elytra subelongate, parallel, rounded at the apex, finely serrulate on the sides, 
the apical margin denticulate ; each elytron with ten, at the extreme base with eleven, 
regular rows of punctures, their interstices thickened, reticulate; the second and fourth
