50 . PHYTOPHAGA. 
I. Elytra each with eight rows of punctures. 
1. Apices of' the elytra conjointly emarginate at the sutural angle. 
1. Chalepus morio, (Tab. III. fig. 4.) 
Hispa morio, Fabr. Syst. t. 2. f. 60. 
Sat elongatus, niger, subtus nitidus, supra subnitidus; thorace transverso, subconico, disco utringue calloso, 
medio rude foveolato-punctato ; elytris parallelis, ad suturam late subquadrato-emarginatis, utrisque octo- 
seriato-punctatis, interstitiis granulosis, planis, interspatio secundo costato. 
Long. 24 lin. 
Hab. Mexico, Toluca, Guanajuato (Sallé). 
Head moderately produced between the eyes; vertex and front trisulcate. Antenne 
very slightly thickened towards the apex; two lower joints equal in length, the third 
as long as the preceding two united. Thorax transverse, subconic ; sides nearly straight, 
converging from the base to the apex; disc with a longitudinal callosity on either side, 
closely and coarsely punctured. Elytra broader than the thorax, parallel, broadly sub- 
quadrate-emarginate at the suture, the sutural angle acute; lateral margin obsoletely, 
the apical one distinctly, serrulate; each elytron with eight rows of punctures, the 
second interspace, together with the suture, costate; interstices between the punctures 
granulose, plane. 
The original type of Hispa morio, Fabr., is in all probability lost. I have therefore, 
following Dr. Chapuis, adopted the Fabrician name, by which this species is known in 
most collections; the diagnosis given by Fabricius is extremely brief, and the locality 
given merely as South America. 
2. Chalepus championi. 
Elongatus, niger, nitidus ; pectore femoribusque flavis, his ad apicem nigro maculatis; capite fulvo trimaculato ; 
antennis ad corporis longitudinem fere equalibus, articulis intermediis compressis, dorso modice cristatis ; 
thorace crebre foveolato-punctato, utrinque late flavo-fulvo vittato; elytris subparallelis, apicem versus 
leviter ampliatis, apice rotundatis, ad suturam late quadrato-emarginatis; lateribus tenuiter, apice magis 
fortiter, serrulatis ; modice convexis, utrisque octo-seriato-punctatis, interspatiis alternis modice costatis ; 
flavo-fulvis, vitta suturali plagaque magna apicali nigris.

Hab. Panama, Volcan de Chiriqui (Champion). 
Front rather strongly produced between the eyes, irregularly grooved. Vertex smooth ; 
a patch on either side of the neck, together with one on the front, extending downwards 
to the base of the antenne, fulvous. Antenne nearly four fifths the length of the body ; 
first and second joints subovate, equal, the third and the following three compressed, 
cristate, the third equal in length to the first and second united, the sixth and following 
ones cylindrical. Thorax nearly one fourth broader than long at the base, slightly 
converging towards the apex, sides subangulate, anterior angle armed with a short 
oblique tooth; upper surface cylindrical on the sides, flattened on the disc, closely
