54 PHYTOPHAGA. 
Head smooth; the interocular space rather strongly produced, its apex angulate. 
Antenne nearly half the length of the body, filiform, moderately robust, slightly attenu- 
ated at the apex; joints cylindrical. Thorax transverse; sides obtusely subangulate- 
rotundate, nearly straight and parallel behind the middle; subcylindrical, slightly 
flattened transversely on the hinder disc, strongly and closely punctured. Elytra 
natrowly oblong; sides straight, slightly diverging from the base towards the hinder 
angle; apex obtusely rounded, finely serrulate; each elytron with eight, at the extreme 
base with nine, regular rows of punctures; the second, fourth, and sixth interspaces, 
together with the suture, moderately costate. 
The apical patch on the elytra varies greatly in size; in var. A, from Guatemala, it 
is entirely obsolete. 
9. Chalepus amicus. (Tab. III. fig. 7.) 
Sat elongatus, subparallelus, niger ; subtus nitidus, femoribus basi fulvo maculatis ; supra minus nitidus, vertice 
fronteque fulvis, levibus; thorace subcylindrico, pone medium transversim excavato, rude punctato, 
fulvo, vitta lata discoidali lateribusque nigris; elytris fere parallelis, minute serrulatis, utrisque octo- 
basi nono-seriato-punctatis, interspatiis secundo, quarto sextoque costatis; vitta lata laterali a basi ad 
ultra medium extensa, postice angusta, linea brevi nigra notata, fulva ornatis. 
Long. 13-2 lin. 
Hab. Panama, David, Bugaba 800 to 1500 feet (Champion). 
Vertex and front smooth, impunctate, the latter obsoletely sulcate. Antenne nearly 
half the length of the body, filiform, slightly thickened towards the apex; joints 
cylindrical, the third short, scarcely longer than the second. Thorax broader than 
long, subcylindrical; sides converging from base to apex, more quickly converging and 
sinuate before the middle, the latter obtusely rounded, anterior angle acute; disc trans- 
versely excavated behind the middle, coarsely and deeply punctured. Elytra nearly 
parallel, conjointly rounded at the apex, minutely serrulate; each elytron with eight, 
at the extreme base with nine, regular rows of punctures, the second, fourth, and sixth 
interspaces costate. 
This species may be separated from C. terminatus by its longer and narrower form, 
by its broader thorax, and by the more strongly raised costz on the elytra; the fulvous 
apical spot is also absent. 
10. Chalepus terminatus. 
Elongatus, niger, subtus nitidus; abdominis basi, femoribus anticis fere totis, posterioribusque basi, flavis ; 
supra subopacus, capite levi, fronte breviter trisulcata, facie inter oculos thoraceque fulvis, hoc subconico, 
crebre punctato, lateribus fasciaque lata discoidali nigris ; elytris parallelis, apicem versus obsolete ampliatis, 
apice obtuse rotundatis, margine ad apicem obsolete serrulatis ; utrisque octo- basi nono-seriato-punctatis, 
interspatiis secundo, quarto sextoque modice costatis; vitta submarginali a basi ad ultra medium extensa, 
callum humerale amplectente, postice angustata, maculaque apicali, fulvis.
