Thirty-five species of this exclusively Tropical-American genus have been described. 
The range is from the province of Parand (a little outside the southern tropic) 
to the tierras calientes of Mexico; but none have yet been recorded from the 
West Indies.

4, Ommata championella. 
Elongata, linearis, nigra, abdomine sanguineo, elytris utrinque vitta abbreviata basali, femoribusque basi flavis; 
thorace cylindrico, crebre alveolato-punctato; elytris abdominis apicem fere attingentibus, apice recte 
truncatis, juxta marginem tenuiter carinatis, dorso crebre punctatis; pedibus gracilibus, femoribus 
clavatis ; antennis dimidium corporis attingentibus, apicem versus incrassatis, nigris. 
Long. 44 lin. 
Hab. Guaremaua, Calderas (Champion). 
Belongs to the subgenus Eclipta of the monograph of Rhinotragine (Ann. & Mag. 
Nat. Hist. vol. xi. 1873, p. 29), and allied to O. prolixa. The general form is 
remarkably elongate and narrow, and bears much resemblance to that of Odontocera 
gracilis (Klug), with which the species agrees in colours and markings. The absence . 
of vitreous spaces on the elytra (a distinguishing character of the genus Odontocera), 
the smaller size of the insect, and the uniform reticulate-punctate surface of the cylin- 
drical thorax at once enable it to be recognized. 
ODONTOCERA. 
Odontocera, Serville, Ann. Soc. Ent. Fr. 1888, p. 546. 
About thirty species of this elegant genus are known, all Tropical-American.
