CEPHALODONTA. 43 
lateribus angustis vittaque discoidali, scutello, elytrorumque vittis tribus, a basi fere ad medium extensis, 
nigris; antennis filiformibus, articulis cylindricis; thorace punctis magnis rotundatis irregulariter dis- 
positis fortiter i impresso, lateribus vix pone medium angulatis; elytris ante medium parallelis, postice 
leviter ampliatis, apice obtuse rotundatis ; angulo postico spina acuta retrorsum spectante armato ; fortiter 
punctato-striatis, interspatio quarto modice costato. 
Long. 4 lin. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Vertex and front smooth, impunctate. Antenne filiform ; joints cylindrical, the basal 
one short, the second to the fifth nearly equal in length, each twice the length of the first, 
the sixth to the tenth rather shorter (the terminal joint is missing in the single specimen 
before me). Thorax rather broader than long; the sides straight and slightly diverging 
from the base to just behind the middle, thence obliquely converging and feebly 
sinuate to the apex, the anterior angle armed with a short oblique tooth ; disc slightly 
excavated behind the middle, impressed with large round punctures, placed irregularly 
over the surface. Elytra parallel before the middle, slightly dilated posteriorly, hinder 
angle armed with a stout acute tooth; apical margin obtusely rounded, entire; upper 
surface flattened along the suture, convex on the sides ; humeral callus laterally produced, 
acute; each elytron with ten, at the base with eleven, rows of large deeply impressed 
punctures ; fourth interspace subcostate; the black vitte are arranged as follows— 
one sutural, the others (one on either side) sublateral and covering the outer ridge of 
the humeral callus. 
19. Cephalodonta scherzeri. 
Cephalodonta scherzeri, Baly, Cat. Hispide, p. 157°. 
Var. A (mas). Elytrorum apice, plagis irregularibus tribus a basi ad medium extensis, suturaque angusta nigris. 
Var. B (mas). Elytris apice nigris. ee oe 
Hab. Guatema.a, Cordilleras’, (Scherzer); Nicaracva, Chontales (Bel¢, var. B); PANAMA, | 5 ee 
Caldera, Bugaba, David, Volcan de Chiriqui 2500 to 4000 feet (Champion, type and Dent, 
var. var. A). 
A specimen in my collection is labelled ‘“‘Amazons,” but I have reason to believe this 
locality to be wrong. The male in this species has the thorax broader, with its sides 
more distinctly angulate 
Mr. Champion informs me that this species is found in dry places in the thinly 
wooded savanna country of the “ tierra caliente.” 
20. Cephalodonta ampliata. 
Elongata, postice valde ampliata, depressa ; subtus nitida, nigro-picea; pectoris medio femoribusque basi flavis, 
abdomine piceo, flavo variegato; supra subopaca, flava; antennis compressis, verticis macula, thoracis 
vitta discoidali scutelloque, nigris; thorace quam longo vix latiori, crebre punctato, lateribus ante medium 
sinuatis; elytris cuneiformibus, a basi apicem versus valde ampliatis, apice rotundatis, ad suturam sub- 
quadrato-emarginatis, angulo suturali dente acuto armato ; angulo postico obsoleto; striato-punctatis, 
sutura et interspatio quarto costatis; limbo ampliato, sulcis numerosis transversis impresso ; vitta brevi
