Specimen singulum m. in ripis Maha-Oyae fluminis prope Negombo 

 cepi. 



Distinguished by its elongate shape. The head is of a bright 

 green colour, with the labrum and the mandibles of a deep, and 

 the antennae and palpi of a light brown, the latter being darkened 

 towards the end. The thorax is of the same colour as the head, 

 reflecting a copper hue from the back ; its anterior angles are 

 obtuse, the basal ones being right. The elytra are of the same 

 greenish copper colour, but darker ; they are impressed with 

 longitudinal lines, which are bordered on each side by a row of 

 minute hairs; they as well as the abdomen have a yellowish 

 margin.

 nigro-seneis, limbo pedibusque flavis, subtus piceus. Long, corp.

Prsecedenti aflfinis. Caput ante oculos indistinete 2-impressum. 

 Thorax ut in prsecedente sed minor, antice lateribus magis deflexus, 

 linea media impressionibusque basalibus longitudinalibus, praecipue 

 in f. profundioribus. Pedes flavi, trochanteribus spinuhsque castaneis. 

 Elytra pra3cedentis. 



In prov. occid. fluminum lacuumque ripis infrequenter legi. 



Allied to the former, but easily distinguished by size, colour, 

 and sculpture of the thorax. The male is shorter and the 

 female plumper than the former. The thorax is smaller and, 

 as is also the head, of a bright copper colour with greenish 

 sides ; its impressions, especially in the female, are deeper, and 

 its anterior part laterally more deflexed. Moreover the yellowish 

 margin of the abdomen is wanting, and the tooth of the mentum 

 is not excavated. The elytra, antennae and palpi, making allow- 

 ances for size, &c., are the same as those of the former. 



5. Chlcenius rugulosus, N. 



C. subconvexus, subglabratus, thorace occipiteque rugulosis cupreis, 

 elytris nigro-viridibus, pedibus, elytrorum limbo lunulisque api- 

 calibus flavis, subtus piceus, abdomine apice margineque flavis. 

 Long. corp. 6^ lin. 



Caput fronte 2-impressum, subtilissimelongitudinaliter rugulosum. 

 Menti dens laciniis extus rotundatis. Thorax lateribus rotundatus, 

 deflexus, basi sat fortiter angustatus, obsolete 2-impressus, parce 

 punctatus, subtiliter transversim rugulosus. Elytra ut in prse- 

 cedente sed apice utrinque lunula flava signata, ad strias distinctius 

 pilosa, his apicem versus per paria coeuntibus. Pectus abdomeuque 

 picea, hujus segmentis 2 ultimis, prsecedentis dimidio margineque 

 flavis. 



Specimen unicum f. in Ch. pulchri, N. societate cepi.
