Longicorn Coleoptera of Tropical America. 31 



19. Ommata Eunomia^ Newman. 

 Odontocera Eunomiaf Newman, Entomologist, p. 92. 



S. Brazil. 



Described by Newman from a single specimen. In colours 

 the species is variable — the upper surface of the thorax being 

 either wholly black, slightly embrowned in the centre, or 

 wholly fulvous ; and the yellow vitta of the elytra sometimes 

 extends to tlie suture, and is sometimes confined to the disk, or 

 wholly wanting. Throughout all the varieties, however, the 

 front of the head, the four anterior femora, and the basal half 

 of the hind pair are bright fulvous. The elytra scarcely pass 

 the base of the antepenultimate segment, and are sharply 

 sinuate-truncate at the apex. The antennaa have the third to 

 sixth joints linear ; and the rest are not thickened, and only 

 slightly serrated. The thorax is somewhat irregularly reticu- 

 late-punctate. The elytra are closely punctate and obscured 

 by soft incumbent silky jtile. 



20. Ommata brachialis, n. sp. 



0. gracilis, fusco-nigra, infra dense cano pubescens; femoribus 

 anticis fulvis, femoribus posticis basi albo-testaceis. Long. 3-4 

 lin. (J. 



Prov. Rio Janeiro, Brazil {coU. Dr. Baden and H. W. Bates). 



Very closely allied to 0. Eunomia. Elytra more elongate, 

 passing the base of the penultimate segment, and obtusely (not 

 sinuate) truncate at the apex. The head is wholly black ; and 

 the anterior thighs only are fulvous, the extreme base of the 

 other pairs being whitish. The eyes (male) are separated by 

 a narrow space on the forehead. The antennae are three fourths 

 the length of the body, and thickened towards the apex ; they 

 are dull black, with bases of seventh to eleventh joints 

 fulvous ; the third to fifth joints are long, slender, and linear. 

 The thorax is narrow, and reticulate-punctate in three longi- 

 tudinal patches, the interstices being scarcely punctured. The 

 elytra are closely punctured. The legs are long, especially 

 the hind pair, and the thighs distinctly clavate.
