20 PHYTOPHAGA,. 
Mas. Antennis filiformibus, articulo tertio compresso trigonato, quam secundus distincte longiori ; abdominis 
segmento anali leviter sinuato. 
Fem. Antennis ut in ¢ ; abdominis segmento anali integro, obtuso. 
Long. 33 lin. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Head shining, front minutely punctured, a narrow, slightly raised, longitudinal line 
free from punctures. Antenne more than half the length of the body, filiform; basal 
joint clavate, second short, ovate, the third rather longer than the second, moderately 
compressed, trigonate, its apex obliquely truncate, the inner angle acute. Thorax rather 
longer than broad; sides straight and parallel from the base nearly to the apex, thence 
obliquely converging to the anterior angle, the latter not produced, acute ; apical margin 
truncate; disc slightly convex, smooth and shining, obsoletely excavated and impressed, 
and with a few deep punctures on the sides. Scutellum pentagonal, its apex very acute. 
Elytra parallel, rounded at the apex, convex on the sides and at the apex, flattened 
along the suture, finely punctate-striate. 
The present species may be at once known from any of its near allies by its narrower 
form and also by the more elongate thorax. 
28. Cephaloleia leucoxantha. 
Angustata, parallela, nitida, subtus nigra; prothorace, pectoris medio, abdominis limbo femoribusque [his apice 
exceptis | pallide flavis ; supra pallide flava, scutello capiteque nigris ; facie inferiori oreque flavis; antennis 
filiformibus, articulo tertio compresso et trigonato; thorace subquadrato, lateribus rectis; disco levi, ad 
latera vage excavato et tenuiter punctato, macula trigonata nigra ad apicem adfixa ornato; elytris opacis, 
dorso deplanatis, tenuiter punctato-striatis, utrisque macula parva humerali nigra notatis. 
Fem. Abdominis segmento anali leviter bisinuato. 
Long. 34 lin. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Vertex shining, impunctate. Antenne slender, filiform, nearly half the length of the 
body; the third joint compressed, trigonate. Thorax subquadrate, broader than long ; 
sides straight and parallel; disc transversely convex, obsoletely excavated and finely 
punctured on the sides. Elytra elongate, parallel, flattened along the suture, opaque, 
finely punctate-striate. 
The above insect, of which I have only seen a single specimen, agrees with 
C. stenosoma in its narrow form, but differs in its broader thorax, and in the bisinuate 
apical segment of the abdomen in the female. 
29. Cephaloleia bella. 
Elongata, nigra, nitida; thorace, pectoris medio, femoribus abdomineque flavo-fulvis, hoc piceo limbato ; tibiis 
anticis et posticis piceo-fulvis; capite tenuiter punctato, inter antennas plaga subcuneiformi sordide fulva 
instructo; thorace levi, intra latera remote punctato, basi et apice nigro-piceo maculatis ; lateribus fere 
rectis, apice incurvatis, angulo antico antrorsum producto, obtuso; elytris parallelis, disco subdeplanatis, 
ad latera deflexis, sat fortiter punctato-striatis, striis prope suturam et ad marginem sulcatis ; utrisque vitta 
lata, a basi fere ad apicem extensa, apice fere ad suturam intus curvata, flava ornatis,
