Anguste cuneiformis, nitidus ; subtus niger, abdomine pedibusque flavis, tarsis piceis ; supra sordide piceo-fulvus ; 
antennis nigris, extrorsum piceis; thorace transverso, foveolato-punctato, lateribus vittisque discoida- 
libus duabus nigro-piceis ; scutello nigro; elytris oblongis, a basi apicem versus leviter ampliatis, apice 
obtuse rotundatis, margine serrulatis ; utrisque decem- medio nono-seriato-punctatis, interstitiis elevato- 
reticulatis ; interspatiis secundo, quarto, sexto (basi et apice) nec non octavo costatis, callo humerali 
modice lateraliter producto; nigro-piceis, eneo tinctis, maculis parvis numerosis fulvis ornatis. 
Var, A. Antennis totis nigris, thoracis vittis abbreviatis, elytris rufo-piceo variegatis. 
Long. 24 lin. 
Hab. Mexico, Juquila (Hége). 
Head smooth: vertex and front impressed with a longitudinal groove. Antenne 
scarcely longer than the head and thorax, thickened towards the apex, five outer joints 
forming a slender ill-defined club. Thorax transverse; sides angulate, straight and 
parallel from the base to the middle, thence obliquely converging towards the apex, 
the anterior angle produced, acute; upper surface transversely convex, transversely 
depressed and excavated on the hinder disc, deeply foveolate-punctate; the lateral 
margin, together with two discoidal vitte (the latter confluent at the base), nigro- 
piceous. Elytra broader than the thorax, oblong, gradually but slightly dilated from 
the base towards the apex, the latter obtuse; outer margin distinctly but finely serrulate ; 
each elytron with ten, on the anterior disc with nine, rows of punctures, the second, 
fourth, sixth (at base and apex), and the eighth interspaces costate; humeral callus 
laterally produced, obtuse. Broader, and with the humeral callus more distinctly pro- 
duced than in C. vittaticollis, the elytral costee more strongly elevated. 
23. Chalepus viridanus. (Tab. III. fig. 8.) 
Subcuneiformis, subdepressus; subtus niger, nitidus ; pedibus (tibiis apice tarsisque exceptis) flavis, pectoris 
lateribus obscure fulvis ; supra flavus, minus nitidus, scutello, collo utrinque, antennisque piceis; thorace 
sat crebre punctato; elytris decem- medio nono-seriato-punctatis ; prasinis, late flavo limbatis, limbi 
maculis fasciaque subapicali nigris. 
Long. 2 lin. 
Hab. Panama, Caldera in Chiriqui 1200 feet (Champion). 
Interocular space very slightly produced; vertex and front smooth, impunctate, 
obtuse, fulvous, sides of neck nigro-piceous. Antenne longer than the head and thorax, 
thickened towards the apex, joints cylindrical, the five outer ones forming a slender, elon- 
gate club; eyes black. Thorax transverse 3 sides straight and parallel, converging at 
the extreme apex, anterior angle armed with an obtuse tooth; disc transversely convex, 
transversely depressed behind the middle, closely and coarsely punctured, outer limb 
narrowly edged with piceo-fulvous. Elytra oblong, increasing in width from the base 
towards the apex, the latter obtusely rounded ; lateral margin finely, the apical one more 
strongly, serrulate ; each elytron at the base and apex with ten, the middle disc with nine, 
rows of punctures; the second, fourth, sixth (at base and apex), and eighth interspaces
