Hab. Mexico, Playa Vicente (Sallé); Guatemala, Zapote (Champion) ; NICARAGUA, 
Chontales (Janson); Panama, Caldera in Chiriqui 1200 feet, David, Taboga Island 
(Champion). 
Vertex smooth, impunctate ; front longitudinally sulcate ; interocular space moderately 
produced, obtuse. Antenne rather longer than the head and thorax, robust, thickened 
towards the apex; joints cylindrical, the five outer ones forming an ill-defined slender 
club. Thorax broader than long ; sides converging and slightly rounded from base to 
apex, obsoletely angulate; disc transversely convex, excavated transversely behind the 
middle, coarsely and closely punctured ; lateral margin (in some specimens) narrowly 
edged with piceous. Elytra broader than the thorax ; sides slightly enlarged from the 
base towards the apex, the latter obtuse; margin serrulate; each elytron with ten, on 
the anterior disc with nine, rows of punctures, the seventh and eighth rows abbreviated 
posteriorly ; the second, fourth, and sixth interspaces (the last at base and apex) strongly 
costate, the eighth less strongly elevated, its apex cristate, serrulate; the third costa 
arises from the apex of the humeral callus, and runs obliquely downwards to join the 
second one at the termination of its anterior third; its apical portion is confluent with 
the cristate apex of the fourth. 
21. Chalepus subapicalis. 
Anguste oblongus, subcuneiformis, nitidus ; subtus cum capite niger, femoribus anticis basi thoraceque fulvis ; 
supra minus nitidus, piceo-fulvus, elytrorum fascia lata subapicali picea; thorace transverso, subcylin- 
drico, lateribus angulatis, disco postico transversim excavato, subopaco, rude et crebre punctato, margine 
antico lateribusque anguste piceis; elytris oblongis, apicem versus vix ampliatis, apice obtuse rotundatis, 
margine serratis, dorso deplanatis ; utrisque decem- paullo ante medium nono-seriato-punctatis ; interstitiis 
elevato-reticulatis ; interspatiis secundo, quarto et octavo, nec non sexto basi et apice, costatis ; costis 
duabus externis serrulatis. 
Long. 23 lin. 
Hab. Mexico, Juquila, Oaxaca (Sallé). 
Vertex smooth, impunctate; front longitudinally grooved, finely rugose-punctate on 
either side ; interocular space very slightly produced. Antenne slightly longer than 
the head and thorax, robust, slightly increasing in thickness towards the apex. Thorax 
transverse; sides slightly but distinctly angulate, straight and nearly parallel from 
the base to the middle, thence obliquely converging towards the apex; transversely 
convex, excavated on the hinder disc, closely, deeply, and coarsely punctured. Elytra 
broader than the thorax ; sides regularly but only slightly dilated from the base towards 
the apex, the apex itself obtusely rounded, the outer margin rather strongly serrulate ; 
each elytron at the extreme base with ten, just before the middle with nine, rows of punc- 
tures ; second, fourth, and eighth interspaces costate, the sixth also elevated at its base 
and apex.
