36 PHYTOPHAGA. 
This species is apparently rare, as it is not represented in any of the collections from 
Central America now before me.

Elongata, postice sat late ampliata, dorso deplanata ; subtus nigra, nitida ; capite inferiori, thoracis lateribus et 
medio, coxis, femoribus basi abdominisque lateribus sordide fulvis; supra minus nitida, fulva; macula 
verticali, antennis (basi picea excepta) scutelloque nigris; thorace transverso, lateribus basi rectis, 
parallelis, vix pone medium angulatis, hinc ad apicem obliquis, disco transversim convexo, basi excavato, 
crebre et fortiter punctato, nigro trivittato; elytris pone medium valde explanatis, apice late rotundatis, 
ad suturam valde et late emarginatis, serrulatis ; angulo suturali dente brevi ornato, angulo postico obsoleto ; 
disco deplanatis, fortiter punctato-striatis; utrisque bicostatis, limbo profunde punctato ; vitta brevi 
communi basali, bifurcata, nigra ornatis. : 
Var. A. Elytrorum vitta nigra obsoleta. 
Var. B. Elytris apice plagaque subanchoriformi a basi ad medium extensa, nigris. 
Long. 3-4 lin. 
Hab. Panama, Bugaba 800 to 1500 feet, Caldera in Chiriqui 1200 feet (Champion). 
Head rather strongly produced between thé eyes, front coarsely punctured ; inter- 
antennal space with a perpendicular ridge. Antenne half the length of the body, attenu- 
ated at the base and apex, robust; the two lower joints cylindrical, the third (which is 
nearly equal in length to the preceding two united) slightly compressed ; terminal joint 
acute, subuncinate. Thorax about one third broader than long; sides deflexed, 
straight and parallel at the base, distinctly angulate just behind the middle, thence 
straight and obliquely converging towards the apex, anterior angle armed with a small 
obtuse tooth; above transversely convex, deeply and rather broadly excavated on the 
hinder disc, closely and coarsely punctured ;- medial line with a narrow longitudinal 
groove ; a discoidal vitta, together with one on either side, just within the lateral 
margin, black. Scutellum oblong-quadrate. Elytra broader than the thorax, dilated 
from the base towards the posterior angle, the latter broadly rounded; apical margin 
rounded, conjointly emarginate at the suture; sutural angle armed with a short acute 
tooth; lateral margin finely, the apical one more coarsely serrulate; upper surface 
flattened between the humeral calli and also along the anterior two thirds of the suture, 
the calli themselves laterally prominent; disc deeply impressed at the base and apex, 
and with twelve, in the middle with eleven, rows of large round punctures; the third 
and sixth interspaces costate; on the lateral margin of the disc, immediately below the 
humeral callus, is also a short, third costa; dilated limb closely covered with similar 
punctures to those on the disc; at the extreme base, commencing at the scutellum and 
extending downwards for about one fourth the length of the elytron, is a narrow 
sutural black line, its hinder half bifurcate. Legs slender, elongate; thighs more or 
less stained beneath with piceous.
