Head closely rugose-punctate ; interspaces closely elevate-reti-

 surface very closely punctured, more especially on the sides, where

 more finely punctured on their hinder half; excavation below the

4. Colasposoma nitidum, n. sp. 

 Oblongum, convexum, cupreum, nitidum, ore antennisque 

 nigris, his basi cacruleo-nigris ; fronte crebre punctata, 

 utrinque elevato-strigosS, epistomate rugoso-punctato ; tho- 

 race lateribus rotundatis, a basi ad apicem convergentibus, 

 rude subcrebre punctato, lateribus crebre irregulariter 

 punctatis ; elytris fortiter subseriatim punctatis, infra humeros 

 excavatis, interspatiis disci exterioris elevato-reticulatis. 

 Long. 21—3 lin. 

 Hab. Coup. 



Head very closely and coarsely punctured, an oblong space just 

 above the apex of the epistome smooth, impunctate ; sides of the 

 upper portion of the front obliquely elevate-strigose ; antennee 

 three-fourths the length of the body, their lower half nitidous, 

 steel-blue. Thorax very coarsely, closely and irregularly punc- 

 tured on the sides, less closely punctured on the middle disk. 

 Elytra strongly punctured, the punctures of equal strength to the 

 apex, outer half of disk covered with coarse irregular waived 

 reticulations ; the punctures towards the apex of the inner disk 

 arranged in slightly sulcate longitudinal striae.
