22 PHYTOPHAGA. 
In addition to the different pattern of the elytra, this insect is narrower and rather 
more elongate than C. suaveola. 
31. Cephaloleia separata. 
Anguste elongata, nitida ; subtus fulva, thorace utrinque macula, pleuris, genubus, tibiis anticis, dorso, posticis 
quatuor basi et apice, tarsisque nigris; abdominis vitta discoidali plus minusve interrupta nigro-picea; 
supra nigra, fronte tenuiter subcrebre punctata; antennarum articulo tertio trigonato; thorace subquad- 
rato, lateribus rectis, angulo antico obtuso, levi, fulvo, margine apicali medio nigro-piceo; elytris dorso 
deplanatis, subopacis, tenuiter punctato-striatis, utrisque linea marginali basi et apice abbreviata, vittaque 
discoidali a basi fere ad apicem extensa, fulvis, ornatis. 
Mas. Abdominis segmento anali sat profunde sinuato. 
Var. A, Klytrorum linea marginali fulva obsoleta. 
Var. B. Antennis basi piceis, elytris ut in var. A. 
Long. 3 lin. 
Hab. Mexico, Playa Vicente (type), Santecomapam (vars. A and B) (Sailé). 
Front finely and subremotely punctured. Antenne with the second joint short, subtrigo- 
nate ; the third joint rather longer than the second, trigonate, its apex obliquely truncate, 
the inner and upper angle acute. Thorax scarcely broader than long; sides straight and 
parallel, the anterior angle very slightly produced, rounded; disc smooth and shining, 
impunctate ; on the anterior margin is a small ill-defined transverse nigro-piceous patch. 
Elytra parallel, flattened along the disc, very minutely punctate-striate; each elytron 
with a broad fulvous vitta which commences at the base and extends downwards nearly 
to the apex. Medial portion of the apical margin of the abdominal segments more or 
less broadly edged with nigro-piceous. | 
The pattern of the elytra in the typical form of this insect, of which I know only the 
male, is similar to that of C. guadrilineata, but the emargination of the anal segment 
of the abdomen in the male of that species is entirely different; the nigro-piceous 
markings on the abdomen sometimes form a narrow vitta on the medial disc. 
32. Cephaloleia belti. 
Anguste elongata, nigra, nitida; thorace, meso- et metasterno, femoribus [apice exceptis]| tibilisque anticis intus 
flavo-fulvis ; abdomine opaco, disco basali piceo-fulvo; thorace subquadrato, utrinque ad marginem punc- 
tato, vitta lata discoidali, a basi ad apicem extensa, nigra ornato; elytris parallelis, dorso depressis, 
opacis, tenuissime punctato-striatis, utrisque linea marginali, ante apicem abbreviata, nec non vitta lata 
discoidali a basi fere ad apicem extensa, fulvo-flavis. 
Mas. Abdominis segmento anali late sed leviter emarginate, medio obsolete sinuato. 
Fem. Abdominis segmento anali leviter bisinuato. 
Long. 23-3 lin. 
Hab. Nicaracva, Chontales (Belt, Janson). 
Head nitidous, front finely punctured between the eyes. Antenne with the third joint 
slightly longer than the second, compressed, trigonate. Thorax broader than long; 
sides nearly straight and parallel, rounded and converging at the apex, anterior angle 
not produced, rounded ; disc smooth and shining, in some specimens coarsely punctured
