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 antennse 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 w^ell as the abdomen have a yellowish 

 margin. 



4. Chlanius cupricollis, N. 



C. subconvexus, subglabratus, capita thoraceque cupreis, elytris 

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

 m. 5|, f. 6^ liu. 



Prsecedeuti affiuis. Caput ante oculos indistincte 2-impressum. 

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

 liuea media inipressionibusque basalibus longitudiaalibus, prsecipue 

 iu f. profundioribus. Pedes flavi, trocbanteribus spinulisque castaneis. 

 Elytra praecedeutis. 



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 iu the female, are deeper, and 

 its anterior part laterally more deflexed. IMoreover the yellowish 

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

 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, tborace 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 rugulosura. 

 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, bis apicem versus per paria coeuntibus. Pectus abdomenque 

 picea, hujus segmentis 2 ultimis, prsecedentis dimidio margineque 

 flavis. 



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