10 PHYTOPHAGA. 
Head sparingly punctured. Basal joint of the antenne compressed, subclavate; the 
second scarcely more than half the length of the first (the remaining joints in the single © 
specimen before me broken off). Thorax slightly broader than long; sides straight 
and parallel, incurved at the apex; apical angles rounded, distinctly produced ; hinder 
angles slightly produced, acute; disc smooth and shining, sparingly impressed on either 
side with large, round punctures. Scutellum trigonate, slightly longer than broad. 
Elytra parallel, obtusely truncate at the apex, flattened along the suture, finely 
punctate-striate, the striz on the inner side obsoletely sulcate.

Anguste elongata, pallide flava, nitida ; antennis, basi exceptis, scutelloque nigris; thorace subquadrato, levi, 
fere impunctato, plaga magna pentagonata, ab apice fere ad basin extensa, nigra; elytris sat fortiter 
punctato-striatis, punctis pallide piceis; utrisque plaga magna humerali fasciaque vix pone medium, 
communi, nigris. 
Mas. Abdominis segmento anali apice leviter concavo. 
Fem. Abdominis segmento anali obtuso, leviter bisinuato.

Hab. Panama, Volcan de Chiriqui 2500 to 6000 feet (Champion). 
Head smooth and shining, vertex and front impressed with a longitudinal groove. 
Antenne filiform, less than half the body in length, the two lower joints fulvous, more 
or less stained with piceous, the rest black. Thorax subquadrate, scarcely broader than 
long; sides nearly straight and parallel; the anterior angles not produced, obtuse; disc 
smooth and shining, impunctate; a large pentagonal discoidal patch attached by its 
base to the apical margin, its apex extending backwards nearly to the base, black. 
Scutellum longer than broad. Elytra broader than the thorax; sides parallel, very 
slightly dilated near the apex, the latter obtusely rounded ; upper surface moderately 
convex, slightly flattened anteriorly along the suture, regularly and rather strongly 
punctate-striate, the striz faintly sulcate. 
5. Cephaloleia distincta. (Tab. I. fig. 15.) 
Elongata, fulva, nitida ; pectore abdomineque nigro-piceis, pedibus (femoribus basi coxisque exceptis) anten- 
nisque nigris; thorace sparse punctato; elytris parallelis, apice obtuse rotundatis; sat fortiter punctato- 
striatis, punctis piceis. 
Mas. Antennarum articulis basalibus quatuor compressis ; abdominis segmento anali late concavo-emarginato. 
Fem. Antennarum articulis cylindricis ; abdominis segmento anali leviter bisinuato.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet, Bugaba (Champion). 
Head nitidous, very finely and sparingly punctured; face between the antenne with 
a strongly raised longitudinal ridge. Antenne less than half the length of the body, 
joints from the second to the apical one cylindrical in the female, the basal one 
thickened, obliquely compressed at the base; four lower joints in the male compressed 
and dilated, the basal one thickened and subclavate, the following three joints trigonate ; 
the second short, broader than long; the third and fourth less dilated, each longer than
