36. Chalepus rufithorax. 
Elongatus, niger, nitidus, thorace mesosternoque rufo-fulvis ; metasterni medio, abdominis basi scutelloque, 
rufo-piceis ; thorace transverso, lateribus a basi apicem versus convergentibus, leviter trisinuatis, margine 
basali utrinque sat profunde excavato; disco opaco, leviter foveolato, pone medium transversim excavato ; 
elytris basi lobatis ; lateribus parallelis, medio vix constrictis, serrulatis, apice rotundato, breviter spinoso; 
supra granuloso-punctatis, utrisque decem-seriato-punctatis ; interspatiis secundo valde, quarto apice, sexto 
basi et apice extremo, nec non octavo toto, mediocriter costatis. 
Long. 3? lin. 
Hab. Mexico, Tuxtla (Sal/é). 
So closely allied to C. hematoderus, of which species it is possibly only a local form, 
that it will be only necessary to give the principal points of difference: the clypeus is 
rather larger, less distinctly pentangular, and the oblique apical foveee are much smaller 
and narrower ; the sides of the thorax are slightly distinctly trisinuate; the elytra 
are entirely black, and their apical teeth are rather finer; in all other respects it agrees 
with the preceding species. 
37. Chalepus sanguinosus. 
Elongatus, parallelus, niger ; subtus nitidus, supra subopacus ; mesosterno thoraceque sanguineis, scutello piceo ; 
thorace transverso, lateribus trisinuatis, ad apicem convergentibus ; convexo, pone medium sat profunde 
transversim excavato, rude et crebre punctato; elytris parallelis, basi lobatis, apice conjunctim rotundatis, 
denticulatis, lateribus tenuiter serrulatis ; utrisque decem-seriato-punctatis, interstitiis elevato-reticulatis ; 
interspatiis secundo valde, quarto basi et apice, sexto basi, nec non octavo toto, modice costatis. 
Long. 34 lin. 
Hab. Nicaragua (Sallé). 
Very closely allied structurally to the two preceding species. The thorax more 
strongly punctured, its sides distinctly angulate before the middle; the clypeus larger, 
and its apical fovee narrower than in C. hematoderus. 
2. Second, fourth, and eighth interspaces costate, entire. 
38. Chalepus chromaticus. (Tab. III. fig. 22.) 
Elongatus, parallelus ; subtus niger, nitidus ; supra minus nitidus, rufo-fulvus, capite scutelloque nigris ; thorace 
transverso ; lateribus a basi apicem versus convergentibus, subangulato-rotundatis, basi fere rectis; velu- 
tino, vage punctato, lateribus vittaque lata discoidali nigris; elytris parallelis, minute serrulatis, apice 
rotundatis, margine apicali denticulato ; utrisque decem-seriato-punctatis ; interspatiis secundo, quarto 
octavoque, nec non sexto basi et apice, costatis; opacis, costis nitidis; vitta suturali, a basi ad longe pone 
medium producta, postice attenuata, nigra, 
Long. 3-34 lin. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Var. A. Supra flavo-fulvus, elytrorum vitta suturali obsoleta, thoracis vitta discoidali angustata. 
Hab. GuatTemata, San Gerénimo (Champion); Costa Rica (Van Patten). 
Vertex longitudinally grooved; interocular space strongly produced, its apex angu- 
late. Antenne robust, nearly half the length of the body, filiform ; joints cylindrical.
